Résumé :

Este artículo plantea un análisis de Protest-$1 como proyecto artístico-tecnológico multiusuario, interactivo y relacional que permite al usuario un acercamiento cognitivo a la protesta sociopolítica, siendo parte de una manifestación simulada en contra de los bombardeos de Israel sobre Palestina. La instalación se compone de una proyección frontal, dos altavoces y tres dispositivos compuestos de un megáfono y un smartphone, cada uno. El interactor elige las acciones que desea hacer acontecer en el evento de protesta pulsando los botones de la pantalla táctil del teléfono móvil y posteriormente, agita el megáfono con el fin de materializar en la manifestación, mediante el esfuerzo, la acción escogida. A su vez, Protesta-$1 permite a los usuarios luchar para evitar que otro usuario consiga sacar adelante la acción de protesta elegida creando un marco en el que el querer de la mayoría somete siempre a la minoría. Los altavoces emiten la voz de los medios de comunicación que relatan la protesta en forma de noticiario y a tiempo real, permitiendo a los interactores articular la protesta siendo conscientes de la imagen global que se está emitiendo.Palabras clave: INTERACCIÓN MULTIUSUARIO; ARTICULACIÓN; PROTESTA SOCIOPOLÍTICA; MEDIOS DE COMUNICACIÓN; CONECTIVIDAD Simulating socio-political protestAbstractThis paper presents an analysis of Protest-$1: an artistic-technological, multi-user, interactive, relational project that provides the user with a cognitive approach to the socio-political protest by being part of a simulated demonstration against the Israeli bombing of Palestine. The installation comprises a front projection screen, two loudspeakers and three devices each consisting of a megaphone and a smartphone. The person who is interacting selects the actions that he/she wants to make happen during the protest event by pressing the buttons on the touch screen of a mobile phone and then shaking a megaphone so that, through this effort, the chosen action can be implemented in the demonstration. Likewise, by creating a framework in which the wishes of the majority always prevail over those of the minority, Protest-$1 allows the users to fight and thus prevent another user from managing to implement their own chosen protest action. The loudspeakers broadcast the voice of the mass media reporting on the protest in the form of a news bulletin and in real time, thus allowing those interacting to articulate the protest while remaining aware of the global image that is being broadcast.Keywords: INTERACTION; MULTI-USER; ARTICULATION; SOCIO-POLITICAL PROTEST; MASS MEDIA; CONNECTIVITY

Résumé :

Our motivation comes from the need of a tailored computational tool for simulation and prediction of forest fire propagation, to be used by firefighters in Patagonia, Argentina. Based on previous works on Graphic Processing Units (GPU) for fitting and simulating fires in our region, we developed a visualization interface for real time computing, simulation and prediction of fire propagation. We have the possibility of changing the ensemble of raster maps layers to change the region in which fire will propagate.The visualization platform runs on GPUs and the user can rotate and zoom the landscape to select the optimal view of fire propagation. Opacity of different layers can be regulated by the user, allowing to see fire propagation at the same time that underlying vegetation, wind direction and intensity. The ignition point can also be selected by the user, and firebreaks can be plotted while simulation is going on.After the performance of a high number of stochastic simulations in parallel in GPUs, the application shows a map of the final fire surface colored according to the probability that a given cell burns. In this way the user can visually identify the most critical direction for fire propagation, a useful information to stop fire optimizing resources, which is specially important when they are scarce like is the case of our Patagonia region.

Résumé :

Real-time collaborative programming enables a group of programmers to edit shared source code at the same time, which significantly complements the traditional non-real-time collaborative programming supported by version control systems. However, one critical issue with this emerging technique is the lack of integration with non-real-time collaboration. Specifically, contributions from multiple programmers in a real-time collaboration session cannot be distinguished and accurately recorded in the version control system. In this study, we propose a scheme that integrates real-time and non-real-time collaborative programming with a novel workflow, and contribute enabling techniques to realize such integration. As a proof-of-concept, we have successfully implemented two prototype systems named CoEclipse and CoIDEA, which allow programmers to closely collaborate in a real-time fashion while preserving the work's compatibility with traditional non-real-time collaboration. User evaluation and performance experiments have confirmed the feasibility of the approach and techniques, demonstrated the good system performance, and presented the satisfactory usability of the prototypes.

Résumé :

Approved for public release; distribution is unlimited
This thesis explores the accuracy and utility of a framework for recognizing a speaker by his or her voice called the Modular Audio Recognition Framework (MARF). Accuracy was tested with respect to the MIT Mobile Speaker corpus along three axes: 1) number of training sets per speaker, 2) testing sample length and 3) environmental noise. Testing showed that the number of training samples per speaker had little impact on performance. It was also shown that MARF was successful using testing samples as short as 1000ms. Finally, testing discovered that MARF had difficulty with testing samples containing significant environmental noise. An application of MARF, namely a referentially-transparent calling service, is described. Use of this service is considered for both military and civilian applications, specifically for use by a Marine platoon or a disaster-response team. Limitations of the service and how it might benefit from advances in hardware are outlined.

Résumé :

Scientific visualization is primarily concerned with the visual presentation of three-dimensional phenomena in domains like medicine, meteorology, astrophysics, etc. The emphasis in scientific visualization research has been on the efficient rendering of measured or simulated data points, surfaces, volumes, and a time component to convey the dynamic nature of the studied phenomena. With the explosive growth in the size of the data, interactive visualization of scientific data becomes a real challenge. In recent years, the graphics community has witnessed tremendous improvements in the performance capabilities of graphics processing units (GPUs), and advances in GPU-accelerated rendering have enabled data exploration at interactive rates. Nevertheless, the majority of techniques rely on the assumption that a true three-dimensional geometric model capturing physical phenomena of interest, is available and ready for visualization. Unfortunately, this assumption does not hold true in many scientific domains, in which measurements are obtained from a given scanning modality at sparsely located intervals in both space and time. This calls for the fusion of data collected from multiple sources in order to fill the gaps and tell the story behind the data. For years, data fusion has relied on machine learning techniques to combine data from multiple modalities, reconstruct missing information, and track features of interest through time. However, these techniques fall short in solving the problem for datasets with large spatio-temporal gaps. This realization has led researchers in the data fusion domain to acknowledge the importance of human-in-the-loop methods where human expertise plays a major role in data reconstruction. This PhD research focuses on developing visualization and interaction techniques aimed at addressing some of the challenges that experts are faced with when analyzing the spatio-temporal behavior of physical phenomena. Given a number of datasets obtained from different measurement modalities and from simulation, we propose a generalized framework that can guide research in the field of multi-sensor data fusion and visualization. We advocate the use of GPU parallelism in our developed techniques in order to emphasize interaction as a key component in the successful exploration and analysis of multi-sourced data sets. The goal is to allow the user to create a mental model that captures their understanding of the spatio-temporal behavior of features of interest; one which they can test against real data measurements to verify their model. This model creation and verification is an iterative process in which the user interacts with the visualization, explores and builds an understanding of what occurred in the data, then tests this understanding against real-world measurements and improves it. We developed a system as a reference implementation of the proposed framework. Reconstructed data is rendered in a way that completes the users' cognitive model, which encodes their understanding of the phenomena in question with a high degree of accuracy. We tested the usability of the system and evaluated its support for this cognitive model construction process. Once an acceptable model is constructed, it is fed back to the system in the form of a reference dataset, which our framework uses to guide the real-time tracking of measurement data. Our results show that interactive exploration tasks enable the construction of this cognitive model and reference set, and that real-time interaction is achievable during the exploration, reconstruction, and enhancement of multi-modal time-variant three-dimensional data, by designing and implementing advanced GPU-based visualization techniques.

Résumé :

A new approach is proposed to transparently share familiar single-user editors without modifying their source code. This approach tweaks a classic diff algorithm to derive edit scripts between document states. Concurrent edit scripts are merged to synchronize states of coauthoring sites. Our concept-proving prototype currently works with familiar, heterogeneous text editors such as GVim and WinEdt that can be adapted to support two basic interfaces, GetState and SetState. The adaption is less expensive and more robust than recent approaches such as ICT and CoWord, which must understand and translate editing operations at the operating system level. Experimental data show that our approach is able to provide sufficient performance for near-realtime group editing.

Résumé :

AbstractThis paper introduces a proof of concept software reasoner that aims to detect whether an individual user is in need of cognitive assistance during a typical Web browsing session. The implemented reasoner is part of the Easy Reading browser extension for Firefox. It aims to infer the user’s current cognitive state by collecting and analyzing user’s physiological data in real time, such as eye tracking, heart beat rate and variability, and blink rate. In addition, when the reasoner determines that the user is in need of help it automatically triggers a support tool appropriate for the individual user and Web content being consumed. By framing the problem as a Markov Decision Process, typical policy control methods found in the Reinforcement Learning literature, such as Q-learning, can be employed to tackle the learning problem.

Résumé :

Abstract The Microsoft® Windows NT™ operating system is inappropriate for “hard” real-time applications that require a deterministic response as might be required in a closed-loop control system where safety is an issue. There are third party development packages that extend NT so that it can be used in a “hard” real-time system. These tools cost several times more than the cost of the PC hardware and this is too expensive for most educational purposes. An example of how “soft” real-time applications can be run under Windows NT using only the Visual C compiler is presented in this article. The multimedia timer and the high performance counter are used in the example to provide a user mode “pseudo-interrupt”. The example is an animated, second order, spring-mass-damper system with a frame time of 25 milliseconds. A circular buffer is used for data storage. The example program can be modified for other “soft” real-time applications and access to the source code is provided.

Résumé :

Tube Hydroforming (THF) is a metal-forming process that uses a pressurized fluid in place of a hard tool to plastically deform a given tube into a desired shape. In addition to the internal pressure, the tube material is fed axially toward the die cavity. This process has various applications in the automotive, aerospace, and bicycle industries. Accurate coordination of the fluid pressure and axial feed, collectively referred to as a loading path, is critical to THF. Workable loading paths are currently determined by trial and error, which can be time consuming. This paper discusses an innovative technique for developing an interactive, real-time database that would be able to predict loading paths for typical classes of THF products and hence, reduce the computational time required. By classifying most of the commercial THF parts into families, parameters such as material properties, part geometry, and tribological factors were simulated by category and stored in the database. Multidimensional cubic spline interpolation was implemented to enable an end user to request from the database a loading path for a wide range of conditions. Test results from the database for different THF families were shown to approximate the simulated results. In addition, by reducing the computation time, the use of interpolation techniques eliminates the need for carrying out multiple simulations for similar THF parts.

Résumé :

This paper describes the results of real-time, on-line performance monitoring of two gas turbines over a period of five months in 1997. A commercially available software system is installed to monitor, analyze and store measurements obtained from the plant’s distributed control system. The software is installed in a combined-cycle, cogeneration power plant, located in Mass., USA, with two Frame 7EA gas turbines in April 1997. Vendor’s information such as correction and part load performance curves are utilized to calculate expected engine performance and compare it with measurements. In addition to monitoring the general condition and performance of the gas turbines, user-specified financial data is used to determine schedules for compressor washing and inlet filter replacement by balancing the associated costs with lost revenue. All measurements and calculated information are stored in databases for real-time and historical trending and tabulating. The data is analyzed ex post facto to identify salient performance and maintenance issues.

Résumé :

Abstract Natural gas has become one of the major sources of energy for homes, public buildings and businesses, therefore gas storage is particularly important to ensure continuous provision compensating the differences between supply and demand. Stogit, part of Snam group, has been carrying out gas storage activities since early 1960's. Natural gas is usually stored underground, in large storage reservoirs. The gas is injected into the porous rock of depleted reservoirs bringing the reservoir nearby to its original condition. Injected gas can be withdrawn depending on the need. Gas market demands for industries and homes in Italy are mostly guaranteed from those Stogit reservoirs even in periods when imports are in crisis. Typically, from April to October, the gas is injected in these natural reservoirs that are "geologically tested"; while from November to March, gas is extracted from the same reservoirs and pumped into the distribution networks to meet the higher consumer demand. Thirty-eight (38) wells, across nine (9) depleted fields, are completed with downhole quartz gauges and some of them with fiber-optics gauges. Downhole gauges are installed to continuously measure and record temperature and pressure from multiple reservoirs. The Real Time data system installed for 29 wells is used to collect, transmit and make available downhole data to Stogit (Snam) headquarter office. Data is automatically collected from remote terminal units (RTUs) and transferred over Stogit (Snam) network. The entire system works autonomously and has the capability of being remotely managed from anywhere over the corporate Stogit (Snam) IT network. Historical trends, including fiber optics gauges ones, are visualized and data sets could be retrieved using a fast and user-friendly software that enables data import into interpretation and reservoir modeling software. The use of this data collection and transmission system, versus the traditional manual download, brought timely data delivery to multiple users, coupled with improved personnel safety since land travels were eliminated. The following pages describe the case study, lessons learned, and integrated new practices used to improve the current and future data transmission deployments.

Résumé :

"USER-CHI is a H2020 research and innovation project, aimed at unlocking the massive potential of electromobility in Europe. This will be achieved by integrating different innovative charging technologies with a holistic perspective, putting the user at the centre and empowering it, and exploiting the synergies between electromobility and the process of greening and smartification of the grid. This process is taking place for achieving the energy transition in Europe, that together with the integration of novel technological tools, business models and regulatory measures, will transform the current scenario. This transformation will generate a financially attractive ecosystem, which improves the user experience of EV drivers. The integrated smart solutions, novel business models and new regulatory framework conditions will be demonstrated and validated in 5 urban areas all along the European territory: Barcelona metropolitan area (Spain), Rome (Italy), Berlin (Germany), Budapest (Hungary), and Turku (Finland). In addition, these 5 sites act as connecting nodes of the key Mediterranean and Scandinavian-Mediterranean TEN-T corridors, which will also be part of demonstration actions. During the project’s first year, The Instituto de Biomecánica (IBV) is leading the generation of the technical specifications for defining new charging infrastructures. This process will be addressed following the user experience principles, achieving a deep knowledge of EV drivers' charging preferences and patterns in order to increase their acceptance. EV supply equipment specifications will be generated both, for slow charging and ultrafast charging applications, proposing a framework for the definition and implementation of USER-CHI solutions, ensuring that they are well-aligned with users’ needs and expectations. This paper will focus on the presentation of the results generated along qualitive user research. These results point out that the EVs acceptance and the technology maturity are closely related to the charging infrastructure broaden, mainly in inter-urban areas. Real time information, usage regulation of charging points and the improvement of charging system’s using experience (time cost reduction and plug standardisation), also arise as key factors."

Résumé :

Abstract With the development of industrial automation and artificial intelligence, robotic systems are developing into an essential part of factory production, and the human-robot collaboration (HRC) becomes a new trend in the industrial field. In our previous work, ten dynamic gestures have been designed for communication between a human worker and a robot in manufacturing scenarios, and a dynamic gesture recognition model based on Convolutional Neural Networks (CNN) has been developed. Based on the model, this study aims to design and develop a new real-time HRC system based on multi-threading method and the CNN. This system enables the real-time interaction between a human worker and a robotic arm based on dynamic gestures. Firstly, a multi-threading architecture is constructed for high-speed operation and fast response while schedule more than one task at the same time. Next, A real-time dynamic gesture recognition algorithm is developed, where a human worker’s behavior and motion are continuously monitored and captured, and motion history images (MHIs) are generated in real-time. The generation of the MHIs and their identification using the classification model are synchronously accomplished. If a designated dynamic gesture is detected, it is immediately transmitted to the robotic arm to conduct a real-time response. A Graphic User Interface (GUI) for the integration of the proposed HRC system is developed for the visualization of the real-time motion history and classification results of the gesture identification. A series of actual collaboration experiments are carried out between a human worker and a six-degree-of-freedom (6 DOF) Comau industrial robot, and the experimental results show the feasibility and robustness of the proposed system.

Résumé :

Abstract PTTEP's natural gas fields in Gulf of Thailand, has encountered losses in Condensate yield due to suboptimal operating conditions as variation in feed compositions occurs when production line up changes. As a result of this suboptimal operation, some light Condensate is lost into gas phase resulting in lower overall profitability. As part of company's Digital Transformation initiatives, a Condensate Stabilizer Optimization (CSO) solution has been implemented to minimize or eliminate these losses. The objective of CSO is to provide real-time recommended operating conditions to maximize condensate production while maintaining sale condensate specification using optimization technology that considers all relevant condensate stabilization process parameters. The CSO solution leverages Multivariable Predictive Control or Model Predictive Control (MPC) technology and communicates the obtained results to offshore teams via an online web user interface. Besides the dynamic models and MPC technology, the solution also includes an important component of the CSO solution which is the web based online dashboards as they are the key to communicate between the solution and the users. The dashboards include the following key features: – Key operating parameters of Condensate Stabilizer Units including Controlled, Manipulated, and Disturbance Variables – Recommended optimal values of Manipulated Variables to achieve maximum condensate production – Difference between actual vs predicted RVP. This is to visualize current model accuracy – Captured Benefit As of December 2021, the CSO solution has been fully utilized for 5 months, i.e. Go-Live since August 2021. During this period, it has successfully delivered not only safe operating window but also benefits which adds up to 1.49 MUSD/year. As the benefits of the solution have been proven, a plan to proceed with Phase 2 of this project, in which the CSO solution will be integrated with the Distributed Control System (DCS) allowing MPC Controller to automatically adjust process parameters to achieve the most optimal conditions, has been set. Apart from process optimization, the CSO solution can be used to evaluate operating scenarios based on given simulated process parameters, thus becoming a true "Digital Twin" of the Condensate Stabilizer that can replicate its operation at different operating conditions.

Résumé :

Enbridge Pipelines remotely controls the flow of approximately two-thirds of Canada’s crude oil and refined products produced from the Western Canadian Sedimentary basin through the Enbridge mainline pipeline system. These various products divided into batches run though multiple terminal systems. Each terminal site is unique and requires a multitude of specialized control systems to maintain its various flow patterns. To efficiently control these terminals Enbridge operators use the custom built PROCYS SCADA system. This system contains a graphical user interface containing schematics and panels that allow operator view and control. As part of this system a subset of control panels were developed and labeled swing panels. Swing panels allow operators to safely and efficiency run product through the various systems within a terminal. Swing panels have been in successful operation for over 10 years, however their development and maintenance cycles were less than optimal for operators and SCADA support staff. For this reason the Enbridge Terminal swing panel system was redesigned. These second generation swing panels were designed to use XML input files and Perl scripting to allow for automated construction. By encapsulating terminal swings in XML the swing panels are easier to maintain and build. This re-design resulted in a system of more functional, usable, and maintainable swing panels. The following paper will discuss this project in more detail.

Résumé :

[Extract from Executive Summary] The competition for space from competing sectors in the coastal waters of Scotland has never been greater and thus there is a growing a need for interactive seascape planning tools that encompass all marine activities. Similarly, the need to gather data to inform decision makers, especially in the fishing industry, has become essential to provide advice on the economic impact on fishing fleets both in terms of alternative conservation measures (e.g. effort limitations, temporal and spatial closures) as well as the overlap with other activities, thereby allowing stakeholders to derive a preferred option. The SIFIDS project was conceived to allow the different relevant data sources to be identified and to allow these data to be collated in one place, rather than as isolated data sets with multiple data owners. The online interactive tool developed as part of the project (Work Package 6) brought together relevant data sets and developed data storage facilities and a user interface to allow various types of user to view and interrogate the data. Some of these data sets were obtained as static layers which could sit as background data e.g. substrate type, UK fishing limits; whilst other data came directly from electronic monitoring systems developed as part of the SIFIDS project. The main non-static data source was Work Package 2, which was collecting data from a sample of volunteer inshore fishing vessels (<12m). This included data on location; time; vessel speed; count, time and position of deployment of strings of creels (or as fleets and pots as they are also known respectively); and a count of how many creels were hauled on these strings. The interactive online tool allowed all the above data to be collated in a specially designed database and displayed in near real time on the web-based application.

Résumé :

The Indiana Department of Transportation (INDOT) operates a fleet of nearly 1100 snowplows and spends up to $60M annually on snow removal and de-icing as part of their winter operation maintenance activities. Systematically allocating resources and optimizing material application rates can potentially save revenue that can be reallocated for other roadway maintenance operations. Modern snowplows are beginning to be equipped with a variety of Mobile Road Weather Information Sensors (MARWIS) which can provide a host of analytical data characterizing on-the-ground conditions during periods of wintry precipitation. Traffic speeds fused with road conditions and precipitation data from weather stations provide a uniquely detailed look at the progression of a winter event and the performance of the fleet. This research uses a combination of traffic speeds, MARWIS and North American Land Data Assimilation System (NLDAS) data to develop real-time dashboards characterizing the impact of precipitation and pavement surface temperature on mobility. Twenty heavy snow events were identified for the state of Indiana from November 2018 through April 2019. Two particular instances, that impacted 182 miles and 231 miles of interstate at their peaks occurred in January and March, respectively, and were used as a case study for this paper. The dashboards proposed in this paper may prove to be particularly useful for agencies in tracking fleet activity through a winter storm, helping in resource allocation and scheduling and forecasting resource needs.

Résumé :

Although nitrate fertilizers are critical for enhancing crop production, excess application of nitrate fertilizer can result in ground water contamination leading to the so called "nitrate problem". Health and environmental problems related to this "nitrate problem" have led to serious concerns in many parts of the world including the United States and Israel. These concerns have resulted in legislation limiting the amount of nitrate N in drinking water to 10mg/g. Development of a fast, reliable, nitrate sensor for in-situ application can be extremely useful in dynamic monitoring of environmentally sensitive locations and applying site-specific amounts of nitrate fertilizer in a precision farming system. The long range objective of this study is to develop a fast, reliable, real-time nitrate sensor. The specific objective of this one year feasibility study was to explore the possible use of nitrate sensor based on mid-IR spectroscopy developed at UCD along with the silver halide fiber ATR (i.e. attenuated total internal reflection) sensor developed at TAU to detect nitrate content in solution and soil paste in the presence of interfering compounds. Experiments conducted at Technion and UCD clearly demonstrate the feasibility of detecting nitrate content in solutions as well as soil pastes using mid-IR spectroscopy and an ATR technique. When interfering compounds such as carbonates, bicarbonates, organic matter etc. are present special data analysis technique such as singular value decomposition (SYD) or cross correlation was necessary to detect nitrate concentrations successfully. Experiments conducted in Israel show that silver halide ATR fiber based FEWS, particularly flat FEWS, resulted in low standard error and high coefficient of determination (i.e. R² values) indicating the potential of the flat Fiberoptic Evanescent Wave Spectroscopy (FEWS) for direct determinations of nitrate. Moreover, they found that it was possible to detect nitrate and other anion concentrations using anion exchange membranes and M1R spectroscopy. The combination of the ion-exchange membranes with fiberoptices offers one more option to direct determination of nitrate in environmental systems.

Résumé :

The Indiana Department of Transportation (INDOT) uses about 600 digital cameras along populated Indiana highways in order to monitor highway traffic conditions. The videos from these cameras are currently observed by human operators looking for traffic conditions and incidents. However, it is time-consuming for the operators to scan through all video data from all the cameras in real-time. The main objective of this research was to develop an automatic and real-time system and implement the system at INDOT to monitor traffic conditions and detect incidents automatically. The Transportation and Autonomous Systems Institute (TASI) of the Purdue School of Engineering and Technology at Indiana University-Purdue University Indianapolis (IUPUI) and the INDOT Traffic Management Center have worked together to research and develop a system that monitors the traffic conditions based on the INDOT CCTV video feeds. The proposed system performs traffic flow estimation, incident detection, and the classification of vehicles involved in an incident. The goal was to develop a system and prepare for future implementation. The research team designed the new system, including the hardware and software components, the currently existing INDOT CCTV system, the database structure for traffic data extracted from the videos, and a user-friendly web-based server for identifying individual lanes on the highway and showing vehicle flowrates of each lane automatically. The preliminary prototype of some system components was implemented in the 2018–2019 JTRP projects, which provided the feasibility and structure of the automatic traffic status extraction from the video feeds. The 2019–2021 JTRP project focused on developing and improving many features’ functionality and computation speed to make the program run in real-time. The specific work in this 2021–2022 JTRP project is to improve the system further and implement it on INDOT’s premises. The system has the following features: vehicle-detection, road boundary detection, lane detection, vehicle count and flowrate detection, traffic condition detection, database development, web-based graphical user interface (GUI), and a hardware specification study. The research team has installed the system on one computer in INDOT for daily road traffic monitoring operations.

Texte intégral

Résumé :

This toolkit provides guidance on using Oxfam’s Household Care Survey (HCS) methodology, which was developed by Oxfam as part of the WE-Care initiative to transform the provision of unpaid care and domestic work (UCDW). UCDW underpins all our lives yet is overwhelmingly provided by women and girls. Recognising UCDW is essential for any initiative that aims to understand and address gender inequality. The HCS is a quantitative survey tool that generates context-specific evidence on how women, men and children spend their time, how care is provided, by whom, and the main factors that affect people’s responsibilities for UCDW, such as access to care services, infrastructure and social norms. The HCS can be used to generate a baseline, or to measure the impact of a specific policy or programme. The methodology can be integrated into different projects with different objectives and adjusted for use in various contexts. The HCS toolkit is designed to be used by development practitioners, policy makers, employers, academics and researchers. Part A provides guidance for planning, collecting, analysing and using HCS data. Part B provides guidance for understanding, adjusting and using the HCS questions. Both sections should be read before undertaking the survey.
