The comfort of the operators in the cabins of vehicles is getting an increasingly important issue. At first glance, the cabins of professional machines (earth-moving equipment, busses, harvesting equipment) might look modern and highly comfortable. However, this does not imply that the cabins actually are comfortable, especially in the long term...

The objectives of this study were to examine the association between work-related upper limb disorders (WRULDs) and duration of computer and mouse use, to investigate differences in these associations between men and women, and to examine whether a possible relationship between duration of computer use and WRULDs was explained by physical or...

The objective of the present study was to gain insight into the effects of precision demands and mental pressure on the load of the upper extremity. Two computer mouse tasks were used: an aiming and a tracking task. Upper extremity loading was operationalized as the myo-electric activity of the wrist flexor and extensor and of the trapezius...

Aim: To compare two different methods for assessment of postural load and duration of computer use in office workers. Methods: The study population existed of 87 computer workers. Questionnaire data about exposure were compared with exposures measured by a standardised or objective method. Measuring true exposure to postural load consisted of an...

This paper describes an intelligent maintenance system for Supporting Crew OPErations (SCOPE). SCOPE supports the astronauts onboard the ISS and helps them to maximize the availability of complex payload systems. SCOPE detects system failures, guides the isolation of the root causes of failure, and presents the relevant repair procedures in...

Elderly users are increasingly becoming active consumers of Internet technologies. Developing websites dedicated to this user group presents several design issues (such as that of 'design for all', participatory design, patient empowerment and cognitive usability assessment methods). SeniorGezond is a health information resource currently under...

One current trend is that content such as e-books, music, videos and now also games and applications are increasingly being distributed across the Internet, and more and more of it is protected by a Digital Rights Management system. Another trend is that this content is consumed using an increasing number and variety of devices, some of which...

This paper examines team work over time in video-mediated non-collocated and traditional face-to-face same-room teams. In a longitudinal between-groups design, 22 three-person teams were tested in 4 1-h test sessions at 2-week intervals. A paper-folding task was designed for the experiment that had the potential to induce differences in team...

Our sensory modalities are specialized in perceiving different attributes of an object or event. This fact is the basis of the approach towards multimodal interfaces we describe in this paper. We rated the match between 20 possible information attributes (common in human computer interaction) and the visual, auditory and tactile sensory systems....

Knowledge of thresholds for perception of inertial motion is needed for the design of simulator motion filters. Experiments have generally been done to measure these thresholds in isolation, one motion at the time. In vehicle simulation however, several motions occur concurrently. In a flight simulator, both inertial and visual cues are provided...

Designers are very well aware of the multi-dimensionality of visual stimuli and extensively use dimensions such as color, form and contrast to encode information. An analogous multi-dimensionality applies to haptic and tactile stimuli. Based on the fact that the human visual system only has two receptor types (cones and rods) while the sense of...

The area of tactile and haptic interactions has produced a number of exemplar systems and an even greater number of research papers. The time has come to systematize the knowledge that has been gained in order to produce guidance. The Ergonomics of Tactile and Haptic Interactions symposium provides an analysis of some of the complexities of...

Smart environments, ambient intelligence and intelligent agents leave the user lost between large amounts of services. Ad-hoc networks, mobile agents and mobile devices make the set of available services dynamic over time and space, increasing the user’s problems to find the service he needs. Earlier, we presented a ServiceMatcher that can find...

Distributed teamwork is not without its difficulties. The detrimental aspects of geographical dispersion of team members on effective teamwork are often invoked to justify reluctance 'to go virtual', despite the fact that for some tasks, and under some conditions, distributed environments may be as good as, or perhaps even better than, meeting...

A long duration of computer use is known to be positively associated with Work Related Upper Extremity Disorders (WRUED). Self-report by questionnaire is commonly used to assess a worker's duration of computer use. The aim of the present study was to assess the validity of self-report and computer use software (WorkPace®) to assess the duration...

On Navy ships, technological developments enable crews to work more efficiently and effectively. However, in such complex, autonomous, and information-rich environments a competition for the users' attention is going on between different information items, possibly leading to a cognitive overload. This overload originates in the limitations of...

Mobile information systems aid first responders in their tasks. Support is often based on mobile maps. People have different preferences for map orientations (heading-up or north-up), but map orientations also have different advantages and disadvantages. In general north-up maps are good for building up situation awareness and heading-up maps...

Tactile and haptic interaction is becoming increasingly important and is no longer restricted to assistive technologies and special purpose computing environments. The technology has gone through numerous breakthroughs and replications and is now entering a period of developing empiricism, the phase in which the first benefits of this new...

In far-side impacts, the time span between the car-to-car impact and the occupant interaction with the interior is longer than 200 ms. In this time span, the reaction of the driver might affect the injury outcome significantly. The objective of this study was to demonstrate the differences between the active and passive human response and the...

To increase police officer awareness of incident locations, the Dutch police developed and implemented a location-based notification system (LBNS). This mobile service notifies police officers proactively to warrants, agreements and police focal points in their current vicinity. To assess the accuracy, efficiency, effectiveness and user...
