Abstract:
This study examined two subjective mental workload assessment scales, the Subjective Workload Assessment Technique (SWAT) and the Modified Cooper-Harper (MCH) Scale. The purpose of this study was to make a direct comparison of the two scales in order to determine if both scales were equally sensitive to changes in task difficulty hence, workload. Forty introductory psychology non-aviator students were trained on an aviation like psychomotor dual-task experiment. Task difficulty was manipulated by presenting the subjects with three (low, moderate, high) levels of wind gust disturbance (turbulence) and requiring them to maintain an assigned altitude and airspeed, while responding to a visual choice reaction time secondary task. The data was analyzed using multivariate statistics. The results of the analysis found that both the SWAT and MCH were sensitive to changes in task difficulty. However, the MCH appeared to be less sensitive than the SWAT.

Abstract:
This study was designed to evaluate the symbiosis of human-machine systems with varying levels of automation. This paper focuses on the protocol methodology employed in the study. The approach required the use of both qualitative and quantitative techniques to derive a comprehensive evaluation of the human-machine system. Protocol Analysis supported by ethnographic software was used to evaluate the verbal transcripts. A qualitative process of code mapping and analysis was developed. The Modified Cooper-Harper scale was used to evaluate mental workload and objective measures of performance provided quantitative data of the system. The results confirmed the usefulness of a proposed classification scheme for human-machine systems. Using the methodology, human capabilities could be assessed against system demands for various configurations of a human-machine system. The importance of understanding the human's role in increasingly automated systems was again demonstrated.

Abstract:
This paper describes an investigation of a workload measurement technique based on pilot control movements. The Dynamic Interface Modeling and Simulation System Product Metric (DIMSS PM) assumes that pilot control activity can be used to evaluate pilot workload. Three qualified test pilots flew the fly-bywire NRC Bell 205 helicopter in a short test program that compared the DIMSS PM with subjective workload ratings and handling qualities ratings. The pilots performed a variation of an ADS-33E bob-up with varying levels of simulated turbulence and modified cyclic control characteristics. Good agreement was found for most in-flight test conditions between DIMSS Workload Metric scores and subjective workload ratings from the Bedford Workload Scale and Cooper-Harper handling qualities ratings. While, the DIMSS Workload Metric did not accurately reflect workload increases due to variations in the cyclic stick characteristics, the metric shows promise as an objective measurement tool of pilot workload in well-defined tests.

Abstract:
Temprina Media Grafika Gresik merupakan perusahaan percetakan yang bergerak di Web Rotary Offset Printing. Perusahaan mampu mencetak 30.000 eksemplar koran dengan jam kerja pukul 20.30-02.00 WIB. Tingkat tekanan kerja tinggi sering dialami operator, dikarenakan deadline cetak koran pendek dan mesin sering mengalami trouble. Selain itu, setiap tahun jumlah operator tetap. Oleh sebab itu, beban kerja merupakan hal utama yang perlu diperhatikan. Penelitian ini menggunakan metode Defence Research Agency Workload Scale (DRAWS) dan Modified Cooper Harper (MCH) dalam pengukuran beban kerja. Dengan DRAWS dapat diukur beban kerja secara umum. Lalu dianalisa lebih lanjut aktivitas (tahapan) kerja yang memiliki beban kerja tinggi dengan MCH. Berdasarkan metode DRAWS, didapat beban kerja sebesar 68,33% (kategori overload) dengan sebaran kerja fisik 44,44% dan mental 55,56%. Variabel Time Pressure mendominasi beban kerja (31,24%). Analisa lanjutan dengan metode MCH didapat bahwa dari 17 aktivitas (tahapan) kerja, 10 berkategori overload, 6 berkategori optimal load, dan 1 berkategori underload. Dari 10 aktivitas (tahapan) kerja berkategori overload (metode MCH) merupakan penyebab kerja mental dominan (sebesar 55,56%) dan berdampak pada variabel Time Presurre sehingga menyebabkan beban kerja tinggi pada operator cetak koran sebesar 68,33% (metode DRAWS). Perbaikan sistem kerja, kondisi lingkungan kerja, juga sistem maintenance dirasa perlu sebagai usulan perbaikan guna menghasilkan proses produksi yang lebih baik.

 ABSTRACT
 Temprina Media Grafika Gresik is a printing company engaged in Web Rotary Offset Printing. The company is able to print 30,000 copies of the newspaper with office hours at 08.30 p.m. - 02.00 a.m. The high level of work pressure is often experienced by the operator, due to the short newspaper print deadlines and the machine often experiences trouble. In addition, every year the number of operators is fixed. Therefore, workload is the main thing that needs attention. This research uses the Defense Research Agency Workload Scale (DRAWS) and Modified Cooper Harper (MCH) methods in measuring the workload of newspaper print operators. With DRAWS general workload can be measured. Then further analyzed work activities (stages) that have a high workload with MCH. Based on the DRAWS method, the value of workload is 68.33% (overload category) with the distribution of physical work 44.44% and mental work 55.56%. Time Pressure variable that dominates workload (31,24%). Further analysis using the MCH method found that out of 17 activities (stages) of work, 10 are categorized as overloads, 6 are categorized as optimal load, and 1 is categorized as underload. Of the 10 activities (stages) of work categorized as overload (MCH method) is the dominant mental work cause (55.56%) and has an impact on the Time Presurre variable, causing a high workload on the newspaper print operator of 68.33% (DRAWS method). Improvement of work systems, working environment conditions, and maintenance systems are felt necessary as a proposed improvement in order to produce a better production process.

Abstract:
Four operator workload (OWL) scales were retrospectively applied to crewmembers of a mobile air defense missile system, LOS-F(H), following a candidate-selection field evaluation: NASA TLX, SWAT, Overall Workload (OW), and the Modified Cooper-Harper (MCH). Jackknife factor analysis revealed the presence of only a single factor (explaining 79.6% of the total variation) and indicated a significant ( p<.0075) ordering of the mean factor loadings: TLX (.935) and OW (.927) were significantly greater than MCH (.862) and SWAT(.860). Comparison with an earlier field test of a remotely piloted vehicle revealed a significant ( p<.00005) interaction of test and ordering of the OWL scales, but TLX and MCH consistently had the respectively highest and lowest loadings across the two field tests. Multiple correlation also revealed a significant ( p < .0001) relationship, R = 0.66, between system performance and TLX. These findings and lessons learned are discussed in the context of the development and validation of a methodology for assessing OWL.

Abstract:
Four empirical operator workload (OWL) scales were applied to ground control operations of the Aquila RPV during a recent field test: NASA TLX, SWAT, Overall Workload (OW), and the Modified Cooper-Harper (MCH). Seventeen sets of individual assessments of mission segments were made by the four members of each of four crews and one replacement crewman. Jackknife factor analysis revealed the presence of only a single factor and indicated that the mean factor loadings formed a consistent ordering ( F(3,48) = 503.5, p < .00005): TLX (.910) > SWAT (.893) > OW (.869) > MCH (.833). ANOVAs also examined the effects of various variables on the composite workload factor scores; significant findings were found which reflected both upon the system and its test. These findings as well as informal lessons learned are discussed in the context of the development and validation of a methodology for assessing OWL.

Abstract:
Operator workload (OWL) scales were used to obtain ratings of generic mission scenarios and tasks for a mobile air defense missile system (LOS-F-H) following a candidate-selection field evaluation. NASA TLX, SWAT, Overall Workload (OW), and the Modified Cooper-Harper (MCH) ratings were obtained from both crew and Subject Matter Experts (SMEs). Jackknife factor analysis revealed the presence of only a single “OWL” factor for both crew and SMEs (explaining 75.9% and 82.6% of the respective total variances) and indicated a significant ( p < 0.00005) ordering of the mean factor loadings: TLX (0.924) was significantly greater than OW (0.905) and MCH (0.904), which were greater than SWAT (0.778). Subsequent analysis of OWL factor scores indicated that the crew and SMEs yielded essentially equivalent evaluations of OWL for the system variables investigated. This analysis also indicated that the highest levels of OWL were obtained for the track-to-intercept task during dual Rotary-Wing (RW) and Fixed-Wing (FW) attacks, although the ID/IFF task during a dual RW attack was almost as high. These findings are discussed in the context of a methodology for assessing OWL.

Abstract:
Den tekniska utvecklingen har lett till att massiva mängder av information sänds, i högahastigheter. Detta flöde måste vi lära oss att hantera. För att maximera nyttan av de nyateknikerna och undkomma de problem som detta enorma informationsflöde bär med sig, börinteraktionskvalitet studeras. Vi måste anpassa gränssnitt efter användaren eftersom denneinte har möjlighet att anpassa sig till, och sortera i för stora informationsmängder. Vi måsteutveckla system som gör människan mer effektiv vid användande av gränssnitt.För att anpassa gränssnitten efter användarens behov och begränsningar krävs kunskaperom den mänskliga kognitionen. När kognitiv belastning studeras är det viktigt att en såflexibel, lättillgänglig och icke-påträngande teknik som möjligt används för att få objektivamätresultat, samtidigt som pålitligheten är av största vikt. För att kunna designa gränssnittmed hög interaktionskvalitet krävs en teknik att utvärdera dessa. Målet med uppsatsen är attfastställa en mätmetod väl lämpad för mätning av interaktionskvalitet.För mätning av interaktionskvalitet rekommenderas en kombinering av subjektiva ochfysiologiska mätmetoder, detta innefattar en kombination av Functional near-infraredspecroscopy; en fysiologisk mätmetod som mäter hjärnaktiviteten med hjälp av ljuskällor ochdetektorer som fästs på frontalloben, Electrodermal activity; en fysiologisk mätmetod sommäter hjärnaktiviteten med hjälp av elektroder som fästs över skalpen och NASA task loadindex; en subjektiv, multidimensionell mätmetod som bygger på kortsortering och mäteruppfattad kognitiv belastning i en sammanhängande skala. Mätning med hjälp av dessametoder kan resultera i en ökad interaktionskvalitet i interaktiva, fysiska och digitalagränssnitt. En uppskattning av interaktionskvalitet kan bidra till att fel vid interaktionminimeras, vilket innebär en förbättring av användares upplevelse vid interaktion.<br>Technical developments have led to the broadcasting of massive amounts of information, athigh velocities. We must learn to handle this flow. To maximize the benefits of newtechnologies and avoid the problems that this immense information flow brings, interactionquality should be studied. We must adjust interfaces to the user because the user does nothave the ability to adapt and sort overly large amounts of information. We must developsystems that make the human more efficient when using interfaces.To adjust the interfaces to the user needs and limitations, knowledge about humancognitive processes is required. When cognitive workload is studied it is important that aflexible, easily accessed and non assertive technique is used to get unbiased results. At thesame time reliability is of great importance. To design interfaces with high interaction quality,a technique to evaluate these is required. The aim of this paper is to establish a method that iswell suited for measurement of interaction quality.When measuring interaction quality, a combination of subjective and physiologicalmethods is recommended. This comprises a combination of Functional near-infraredspectroscopy; a physiological measurement which measures brain activity using light sourcesand detectors placed on the frontal lobe, Electrodermal activity; a physiological measurementwhich measures brain activity using electrodes placed over the scalp and NASA task loadindex; a subjective, multidimensional measurement based on card sorting and measures theindividual perceived cognitive workload on a continuum scale. Measuring with these methodscan result in an increase in interaction quality in interactive, physical and digital interfaces.An estimation of interaction quality can contribute to eliminate interaction errors, thusimproving the user’s interaction experience.
