Abstract:
360-degree video streaming for high-quality virtual reality (VR) is challenging for current wireless systems because of the huge bandwidth it requires. However, millimeter wave (mmWave) communications in the 60 GHz band has gained considerable interest from the industry and academia because it promises gigabit wireless connectivity in the huge unlicensed bandwidth (i.e., up to 7 GHz). This massive unlicensed bandwidth offers great potential for addressing the demand for 360-degree video streaming. This paper investigates the problem of 360-degree video streaming for mobile VR using the SHVC, the scalable of High-Efficiency Video Coding (HEVC) standard and PC offloading over 60 GHz networks. We present a conceptual architecture based on advanced tiled-SHVC and mmWave communications. This architecture comprises two main parts. (1) Tile-based SHVC for 360-degree video streaming and optimizing parallel decoding. (2) Personal Computer (PC) offloading mechanism for transmitting uncompressed video (viewport only). The experimental results show that our tiled extractor method reduces the bandwidth required for 360-degree video streaming by more than 47% and the tile partitioning mechanism was improved by up to 25% in terms of the decoding time. The PC offloading mechanism was also successful in offloading 360-degree decoded (or viewport only) video to mobile devices using mmWave communication and the proposed transmission schemes.

Abstract:
To support 360 virtual reality video streaming services, high resolutions of over 8K and network streaming technology that guarantees consistent quality of service are required. To this end, we propose 360 virtual reality video player technology and a streaming protocol based on MPEG Dynamic Adaptive Streaming over HTTP Spatial Representation Description to support the player. The player renders the downsized video as the base layer, which has a quarter of the resolution of the original video, and high-quality video tiles consisting of tiles obtained from the tiled-encoded high-quality video (over 16K resolution) as the enhanced layer. Furthermore, we implemented the system and conducted experiments to measure the network bandwidth for 16K video streaming and switching latency arising from changes in the viewport. From the results, we confirmed that the player has a switching latency of less than 1000 ms and a maximum network download bandwidth requirement of 100 Mbps.

Abstract:
360∘ panorama video displayed through Virtual Reality (VR) glasses or large screens offers immersive user experiences, but as such technology becomes commonplace, the need for efficient streaming methods of such high-bitrate videos arises. In this respect, the attention that 360∘ panorama video has received lately is huge. Many methods have already been proposed, and in this paper, we shed more light on the different trade-offs in order to save bandwidth while preserving the video quality in the user’s field-of-view (FoV). Using 360∘ VR content delivered to a Gear VR head-mounted display with a Samsung Galaxy S7 and to a Huawei Q22 set-top-box, we have tested various tiling schemes analyzing the tile layout, the tiling and encoding overheads, mechanisms for faster quality switching beyond the DASH segment boundaries and quality selection configurations. In this paper, we present an efficient end-to-end design and real-world implementation of such a 360∘ streaming system. Furthermore, in addition to researching an on-demand system, we also go beyond the existing on-demand solutions and present a live streaming system which strikes a trade-off between bandwidth usage and the video quality in the user’s FoV. We have created an architecture that combines RTP and DASH, and our system multiplexes a single HEVC hardware decoder to provide faster quality switching than at the traditional GOP boundaries. We demonstrate the performance and illustrate the trade-offs through real-world experiments where we can report comparable bandwidth savings to existing on-demand approaches, but with faster quality switches when the FoV changes.

This visual essay deconstructs a four-second experience within a dance performance, In and out of time, which was performed at Dancehouse (Melbourne, AUS) in 2018. It captures the body’s movement as still moments and re-presents them through a tiled image and a video ‘flip-book’ work. Together with language, the visual essay aims to reveal how, over time, the memory of this experience has become magnified and thickened, drawing out new ways of knowing in relation to an embodied experience each time it is recollected.

Abstract:
Inspired by the brain’s structure, we have developed an efficient, scalable, and flexible non–von Neumann architecture that leverages contemporary silicon technology. To demonstrate, we built a 5.4-billion-transistor chip with 4096 neurosynaptic cores interconnected via an intrachip network that integrates 1 million programmable spiking neurons and 256 million configurable synapses. Chips can be tiled in two dimensions via an interchip communication interface, seamlessly scaling the architecture to a cortexlike sheet of arbitrary size. The architecture is well suited to many applications that use complex neural networks in real time, for example, multiobject detection and classification. With 400-pixel-by-240-pixel video input at 30 frames per second, the chip consumes 63 milliwatts.

Abstract:
Numeric hydrologic models can aid in water resource management by providing predictive simulations of water behavior. As computers become more advanced, the models developed also become more complex using more data to represent larger areas for forecasting hydrologic behavior. Unfortunately, as the simulations use more data, the output often becomes difficult to manage and share without investing time and effort into setting up server environments or decreasing the quality of the output to compensate for an efficient and effective user experience. A proposed solution to facilitate the accessibility of massive hydrologic model output is through the web-based visualization tool developed at Carnegie Mellon University called Time Machine. For a more efficient and automated workflow, a Python tool named TMAPS was developed from this research for rendering hydrologic model results, geoprocessing the rendered output, and generating Time Machines seamlessly. The tool can be installed from the CI-WATER GitHub repository and allows the user to 1) select the output parameters and visualization settings desired to be rendered, 2) run the code on a local or HPC setup, and 3) use a web browser interface to view the tiled transient results seamlessly while maintaining high quality. Currently, the only hydrologic model supported is ADHydro - a large-scale high-resolution multi-physics watershed simulation. In an effort to facilitate organizing the library of Time Machine products, an app was created through Tethys - a server-based Django application designed to aid in the development and sharing of water resource engineering apps.

Abstract:
Les dispositifs d'enregistrement vidéo sont souvent équipés de capteurs (smartphones par exemple, avec récepteur GPS, gyroscope, etc.) ou utilisés dans des systèmes où des capteurs sont présents (par exemple, caméras de surveillance, zones avec capteurs de température et/ou d'humidité). Par conséquent, de nombreux systèmes traitent et distribuent la vidéo avec des flux de métadonnées temporels, souvent sous forme de contenu généré par l'utilisateur (UGC). La diffusion vidéo a fait l'objet d'études approfondies, mais les flux de métadonnées ont des caractéristiques et des formes différentes, et il n'existe en pratique pas de méthode cohérente et efficace pour les traiter conjointement avec les flux vidéo. Dans cette thèse, nous étudions les moyens d'améliorer les applications vidéo grâce aux métadonnées temporelles. Nous définissons comme métadonnées temporelles toutes les données non audiovisuelles enregistrées ou produites, qui sont pertinentes à un moment précis sur la ligne de temps du média. ”L'amélioration” des applications vidéo a une double signification, et ce travail se compose de deux parties respectives. Premièrement, utiliser les métadonnées temporelles pour étendre les capacités des applications multimédias, en introduisant de nouvelles fonctionnalités. Deuxièmement, utiliser les métadonnées chronométrées pour améliorer la distribution de contenu pour de telles applications. Pour l'extension d'applications multimédias, nous avons adopté une approche exploratoire et nous présentons deux cas d'utilisation avec des exemples d'application. Dans le premier cas, les métadonnées temporelles sont utilisées comme données d'entrée pour générer du contenu, et dans le second, elles sont utilisées pour étendre les capacités de navigation pour le contenu multimédia sous-jacent. En concevant et en mettant en œuvre deux scénarios d'application différents, nous avons pu identifier le potentiel et les limites des systèmes vidéo avec métadonnées temporelles. Nous utilisons les résultats de la première partie afin d'améliorer les applications vidéo, en utilisant les métadonnées temporelles pour optimiser la diffusion du contenu. Plus précisément, nous étudions l'utilisation de métadonnées temporelles pour l'adaptation multi-variables dans la diffusion vidéo multi-vues et nous testons nos propositions sur une des plateformes développées précédemment. Notre dernière contribution est un système de buffering pour la lecture synchrone et à faible latence dans les systèmes de streaming en direct
Video recording devices are often equipped with sensors (smartphones for example, with GPS receiver, gyroscope etc.), or used in settings where sensors are present (e.g. monitor cameras, in areas with temperature and/or humidity sensors). As a result, many systems process and distribute video together with timed metadata streams, often sourced as User-Generated Content. Video delivery has been thoroughly studied, however timed metadata streams have varying characteristics and forms, thus a consistent and effective way to handle them in conjunction with the video streams does not exist. In this Thesis we study ways to enhance video applications through timed metadata. We define as timed metadata all the non-audiovisual data recorded or produced, that are relevant to a specific time on the media timeline. ”Enhancing” video applications has a double meaning, and this work consists of two respective parts. First, using the timed metadata to extend the capabilities of multimedia applications, by introducing novel functionalities. Second, using the timed metadata to improve the content delivery for such applications. To extend multimedia applications, we have taken an exploratory approach, and we demonstrate two use cases with application examples. In the first case, timed metadata is used as input for generating content, and in the second, it is used to extend the navigational capabilities for the underlying multimedia content. By designing and implementing two different application scenarios we were able to identify the potential and limitations of video systems with timed metadata. We use the findings from the first part, to work from the perspective of enhancing video applications, by using the timed metadata to improve delivery of the content. More specifically, we study the use of timed metadata for multi-variable adaptation in multi-view video delivery - and we test our proposals on one of the platforms developed previously. Our final contribution is a buffering scheme for synchronous and lowlatency playback in live streaming systems

Abstract:
In modern times, procedural content generation sees frequent use in video games, producing anything from graphics to maps and quests. This study focuses on how these techniques can be used to produce forest maps for tactical role-playing games, and how this is applied in particular to Starshard, one such game. The main points addressed are how well the forestry growth simulation algorithm previously implemented in Starshard compares to algorithms based on other popular techniques, how to utilise evaluation and optimisation to produce correct and strategically interesting maps without human interference, and whether or not players can easily perceive a difference between procedural maps and maps designed by humans. With high demand for new algorithms to automate content generation in order to help smaller teams of developers and maintain interest in content post release, there is much value in delving further into less frequently explored aspects such as tile-based maps or player perception of procedural content. In order to answer the research problems, a controlled experiment comparing four forestry generation algorithms was performed, in addition to a study of literature to implement evaluation and optimisation algorithms, and a survey to gauge player reactions to the produced maps. Ultimately, the growth simulation proves to be more successful than alternative algorithms in reducing number of errors in maps. In addition, the results of the survey showed that while players are capable of reliably picking out human created maps, their ratings for procedurally generated maps were not much lower than these and they could frequently mistake procedural maps as being produced by humans.

Abstract:
Esta dissertação de mestrado propõe um algoritmo adaptativo que é capaz de dinamicamente definir partições tile para quadros intra- e inter-preditos com o objetivo de reduzir o impacto na eficiência de codificação. Tiles são novas ferramentas orientadas ao paralelismo que integram o padrão de codificação de vídeos de alta eficiência (HEVC – High Efficiency Video Coding standard), as quais dividem o quadro em regiões retangulares independentes que podem ser processadas paralelamente. Para viabilizar o paralelismo, os tiles quebram as dependências de codificação através de suas bordas, gerando impactos na eficiência de codificação. Este impacto pode ser ainda maior caso os limites dos tiles dividam regiões altamente correlacionadas do quadro, porque a maior parte das ferramentas de codificação usam informações de contexto durante o processo de codificação. Assim, o algoritmo proposto agrupa as regiões do quadro que são altamente correlacionadas dentro de um mesmo tile para reduzir o impacto na eficiência de codificação que é inerente ao uso de tiles. Para localizar as regiões altamente correlacionadas do quadro de uma maneira inteligente, as características da imagem e também as informações de codificação são analisadas, gerando mapas de particionamento que servem como parâmetro de entrada para o algoritmo. Baseado nesses mapas, o algoritmo localiza as quebras naturais de contexto presentes nos quadros do vídeo e define os limites dos tiles nessas regiões. Dessa maneira, as quebras de dependência causadas pelas bordas dos tiles coincidem com as quebras de contexto naturais do quadro, minimizando as perdas na eficiência de codificação causadas pelo uso dos tiles. O algoritmo proposto é capaz de reduzir mais de 0.4% e mais de 0.5% o impacto na eficiência de codificação causado pelos tiles em quadros intra-preditos e inter-preditos, respectivamente, quando comparado com tiles uniformes.
This Master Thesis proposes an adaptive algorithm that is able to dynamically choose suitable tile partitions for intra- and inter-predicted frames in order to reduce the impact on coding efficiency arising from such partitioning. Tiles are novel parallelismoriented tools that integrate the High Efficiency Video Coding (HEVC) standard, which divide the frame into independent rectangular regions that can be processed in parallel. To enable the parallelism, tiles break the coding dependencies across their boundaries leading to coding efficiency impacts. These impacts can be even higher if tile boundaries split highly correlated picture regions, because most of the coding tools use context information during the encoding process. Hence, the proposed algorithm clusters the highly correlated picture regions inside the same tile to reduce the inherent coding efficiency impact of using tiles. To wisely locate the highly correlated picture regions, image characteristics and encoding information are analyzed, generating partitioning maps that serve as the algorithm input. Based on these maps, the algorithm locates the natural context break of the picture and defines the tile boundaries on these key regions. This way, the dependency breaks caused by the tile boundaries match the natural context breaks of a picture, then minimizing the coding efficiency losses caused by the use of tiles. The proposed adaptive tiling algorithm, in some cases, provides over 0.4% and over 0.5% of BD-rate savings for intra- and inter-predicted frames respectively, when compared to uniform-spaced tiles, an approach which does not consider the picture context to define the tile partitions.

Abstract:
A atual problemática da disposição de resíduos eletroeletrônicos estimula a realização de pesquisas visando o reaproveitamento desse tipo de resíduo na fabricação de novos produtos ou na utilização dos mesmos em processos já existentes. O descarte de monitores de computadores e TVs com a tecnologia de tubos de raios catódicos (CRT) não é simples, pois os mesmos contêm metais pesados e há poucas alternativas de reciclagem estabelecidas, o que gera um passivo ambiental ainda sem solução. O CRT corresponde a 80% do peso de um monitor de computador e é constituído por três tipos de vidro, com diferentes composições. A relação aproximada (em % peso) é: 65% painel, 30% funil e 5% pescoço. Entre os diferentes vidros dos quais é fabricado os CRTs, o painel tem altas porcentagens de óxidos de metais alcalino e alcalino-terrosos e assim grande potencial para ser aproveitado como substituto de fritas na formulação de esmaltes cerâmicos. Uma vantagem adicional é o fato de que os metais pesados são estabilizados na forma de óxidos, tendo a mínima dissolução após a sinterização e vitrificação. Neste trabalho as composições químicas do vidro de painel de CRT e da frita foram caracterizadas pela técnica de FRX e ICP-AES. Depois os valores do coeficiente de expansão térmica e a viscosidade como função da temperatura foram calculados usando modelos empíricos que relacionam essas propriedades com a composição química do vidrado, através do software e banco de dados SciGlass®. Substituições parciais de frita por vidro de painel de CRT foram experimentalmente testadas na formulação de um esmalte transparente típico. Suspensões com 10 a 40% em peso de vidro de painel de CRT como substituto da frita tradicional foram preparadas e aplicadas sobre a superfície de substratos de argila conformados por prensagem. Subsequentemente, as placas foram queimadas seguindo um ciclo térmico similar ao utilizado industrialmente. Os valores do coeficiente de expansão térmica foram caracterizados por dilatometria. A viscosidade do esmalte foi medida a temperaturas elevadas (viscosidades baixas). A cor e a transparência dos esmaltes após a queima foram caracterizadas por colorimetria. Em uma análise comparativa, a substituição de 20% em peso de frita por vidro de painel de CRT resultou em revestimentos com propriedades equivalentes as de esmaltes comerciais.
The current problem of disposal of electronic waste stimulates research aiming at the reuse of this type of waste in the manufacture of new products or existing processes. The disposal of computer monitors and televisions based on the technology of cathode ray tube (CRT) is not simple, since they contain heavy metals and there are few recycling alternatives nearby the consumer center, generating an unsolved environmental liability. The CRT corresponds to approximately 85 wt% of a computer monitor, and is composed by three silicate glasses with different compositions, in the approximate proportions (wt%): 65% panel, 30% funnel and 5% neck glass. Among the different glasses of which the CRT\'s are made, the panel has higher percentages of alkali and alkaline earth metal oxides, which thus give them potential to be used as frits substitute in the formulation of ceramic glazes. An additional advantage is the fact that these heavy metals are stabilized in the form of oxides, presenting minimal dissolution after sintering and vitrification. In the present work, the chemical compositions of a CRT\'s panel glass and glaze frits were characterized by XRF and ICP-AES. Then, the value of thermal expansion coefficients and viscosity were calculated as a function of temperature using empirical models that relate such properties with the glass chemical composition, aided by the SciGlass software. The partial replacement of frits for CRT\'s panel glass was experimentally tested in the composition of a typical transparent ceramic glaze. Aqueous suspensions containing 10 to 40 wt% of CRT\'s panel glass as a substitute for the traditional frit were prepared and applied on the surface of substrates formerly obtained by pressing a clay raw material into plates. Subsequently, the plates were fired following a thermal treatment similar to the used industrially. The resulting thermal expansion coefficients were characterized by dilatometry. The glaze viscosity was measured at high temperatures (low viscosities). The color and transparency of the glazes after firing were characterized by colorimetry. In a comparative analysis, the substitution of 20 wt% of frit by CRT\'s panel glass resulted in ceramic tiles with properties equivalent to those of the commercial glazes.

In this thesis, an advanced nighttime video surveillance system is established. The MIIR video capturing is the source that can guarantee clear objects at all distances. Then it will be separated in to channels with the same illumination condition. Those channels can be further utilized for different purposes. For storage purpose, the raw MIIR video can be compressed by simulcast HEVC, MV-HEVC, or 3D-HEVC. All these proposed compression methods are specialized for coding with channels and thus can provide higher compression ratio than the standard HEVC compression. For monitoring purpose, a video summary method for MIIR video is proposed to generate a compact video in which every foreground objects in the image frames are clear and the blinking phenomenon of the raw MIIR video is eliminated for comfortable viewing and surveillance. The summarized video can also streaming via network for remote surveillance. For streaming the MIIR video, the proposed scheme combines multiple connection transmission and HEVC tile coding to achieve a full parallel processing of encode/transmission/decode, and an adaptive tile boundary (ATB) coding method with switch control is applied to minimize the whole playback delay. A database is also established for MIIR video researches.

Dissertação de Mestrado Integrado em Engenharia Electrotécnica e de Computadores apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra
A norma de codificação de vídeo HEVC (High Efficiency Video Coding) surge como sucessora da norma H.264/AVC, em resposta ao rápido aumento do volume de informação em vídeo com resoluções HD e UHD. A nova norma inclui ferramentas para suportar implementações paralelas, como slices, tiles e wavefront parallel processing. Este trabalho propõe um método que ajusta automaticamente a geometria das tiles durante o processo de codificação de vídeo, para equilibrar a distribuição de carga entre as unidades processadoras , num cenário em que cada tile é processada por uma unidade distinta. A solução baseia-se em quatro métodos de estimação de complexidade e um algoritmo que ajusta dinâmicamente as tiles de acordo com a complexidade estimada. Os resultados mostram que o método proposto é capaz de aumentar a eficiência de paralelização, quando comparado com tiles com tamanhos iguais, obtendo-se em média uma redução do tempo de processamento de 6.1% com um aumento de BD-rate entre 0.82% e 1.67%.
The High-efficiency Video Coding (HEVC) standard arises as the successor to the H.264/AVC standard, in response to the rapid increase in HD and UHD digital video information volume. The new standard includes tools to support parallel implementations, such as slices, tiles and wavefront parallel processing. This work proposes a method that automatically adjusts the tile geometry during the video encoding process, to balance the workload distribution among the processing units, assuming that each tile is processed by a different unit. The solution comprises four complexity estimation methods and an algorithm to dynamically adjust the tile geometry. Results show that the proposed method is able to improve the parallelization efficiency compared to the use of same-sized tiles, saving on average 6.1% of the processing time at the cost of an increase in BD-rate between 0.82% and 1.67%.

Abstract:
Existem vários jogos actuais que usam algoritmos para gerar procedimentalmente os seus níveis mas, todos eles, usam mecanismos simples para criar alguma variedade na jogabilidade ou, então, usam sistemas tão complexos que são complicados de compreender e difíceis de reutilizar. Um exemplo recente é o jogo No Man Sky que usa um sistema tão complexo que poucos programadores são capazes de realmente o entender, e portanto, tanto mais difícil de serem capazes de aplicar essa mesma abordagem num projeto próprio. Os sistemas mais simples de geração procedimental são adoptados com mais frequência, seja para criar itens aleatórios, inimigos com comportamentos inprevisiveis ou variações na disposição dos níveis, deixando os entusiastas desta área tecnológica frustrados. O objectivo desta dissertação consistiu na investigação das origens da geração procedimental de niveis com o recurso ao uso de grelhas, o seu uso ao longo dos anos e de que modo essas técnicas podem ser aplicadas a jogos 3D. Para criar uma prova de conceito, o motor gráfico Unity foi usado como base para o desenvolvimento de uma ferramenta — Rubik Mapper— que aplica um algoritmo de criação procedimental de níveis baseado na combinação de módulos.

This chapter considers how girls and boys view the conflict between media consumption and learning in class, focusing on uses of portable media in classroom that take place mostly in secret in the classroom. It compares listening practices in school and at home to bring the institutional structure of kids’ listening practices into relief, and it compares kids uses of portable video gamed devices with MP3 players to explore the gendering of kids’ media consumption. The contrast between discourses of “multitasking” that are volunteered differently by boys and girls suggest that each group sees the fine-grained details of their media interactions as deeply tied up in their social identities in school.

Abstract:
Face-to-Face: The Persistent Power of Cities In a Post-Pandemic Era, is about the way that people and firms are adapting to the world of always-on and everywhere digital access, and what that means for cities and regions. Twenty years after The Death of Distance—and in the midst of a pandemic that has led some to question the future of cities—many people still think that we are on track for ‘business anywhere’. The book shows why that's not the case, and provides a structure for thinking about the next twenty years of social and economic upheaval. It shows how the changing fortunes of cities are tied to the ongoing importance of face-to-face contact to our most valuable industries, and thus why the ‘human touch’ will continue to be crucial in the cities of tomorrow. Drawing on interviews with artists and advertisers, bankers and bakers, software devs and property developers, across some forty interviews we home in on what people actually do and why. ‘Contact’, in all its forms, is shown to still matter hugely to companies and individuals, even in a world with high-quality video conferencing and free online calling. And when the pandemic hit, a further digital survey explored interviewees’ experiences of an ‘e-only’ world, gaining ‘front-line’ insights into the short- and long-terms. The book seeks to provide guidance for city leaders, businesses, policymakers and students of urban and regional planning on how to think about 21st Century urban change.

Abstract:
In intellectual collaborative works with participants between remote sites via WAN, CSCW have been used as general communication tools. Especially, the sharing of various, high-quality digital contents such as various materials, computer graphics or visualization contents, and video streaming by between remote places is important to recognize or analyze to easily refer to these contents. However, the image magnification by general projector and large-sized display equipment is low-resolution, and sufficient quality of contents is not obtained. In this research, the author has constructed a tele-immersive collaborative environment with a tiled display wall. In this environment, the author has implemented an application to display high-resolution real video streaming on a tiled display wall in remote place. By using the application, the author displayed the clear video image of remote place over a wide range. Then, the author conducted experimental verification on the effect for eye-to-eye contact by changing the position of camera on frame of LCDs on tiled display wall, and has collected a lot of knowledge. Moreover, the author has tried realistic display processing of high-resolution astronomical observation image and movie data, and it has enabled observation of the entire image of observation data all over tiled display wall.

Abstract:
Chapter 15 features Abu Bakr al-Baghdadi’s final speech which appeared in an Islamic State video titled ‘In the Hospitality of Amirul-Mu’minin’ on 29 April 2019. Three features are particularly noteworthy. First, Baghdadi uses the speech to demonstrate that he is closely monitoring not only global events and issues but the fortunes of the personnel within his organization. Second, his physical appearance in the video was markedly different to his last appearance in 2014. He was now the guerrilla caliph managing a global insurgency on the run. Third, Baghdadi was projecting his authority as not just Islamic State’s leader but ‘amirul-mu’minin’ (commander of the faithful). Less than six months later, Baghdadi would be killed in a special forces leadership decapitation raid on his hideout in northern Syria. Under his leadership, the Islamic State had become the flagship of the global jihad with provinces around the world.

Abstract:
People can use computationally-enhanced furniture to interact with distant friends and places without cumbersome menus or widgets. We describe computing embedded in a pair of tables and a chair that enables people to experience remote events in two ways: The TeleTables are ambient tabletop displays that connect two places by projecting shadows cast on one surface to the other. The Window Seat rocking chair through its motion controls a remote camera tied to a live video feed. Both explore using the physical space of a room and its furniture to create “bilocative” interfaces.
