In this paper we investigate whether Virtual Reality (VR) and Augmented Reality (AR) offer potential for the training of manual skills, such as for assembly tasks, in comparison to conventional media. We present results from experiments that compare assembly completion times for a number of different conditions. We firstly investigate completion times for a(More)
Human error is a significant contributor to product failure. However, it is uncommon for designers to explicitly consider the potential for human error in the design of products. In this chapter, it is proposed that ‘human error’ arises as a consequence of the interaction between user and product, and that modeling this interaction can allow insight into(More)
This paper presents a tool to measure the comfort of wearable computers. The comfort rating scales (CRS) measure wearable comfort across 6 dimensions. These dimensions are Emotion, Attachment, Harm, Perceived change, Movement and Anxiety. This paper also presents two studies in which the CRS have been used to assess the comfort of two types of wearable(More)
In this paper, current applications of wearable computers are reviewed and categorized according to dimensions of “time” and “reference.” The time dimension is based on whether the system uses information that is stored, information that is current, or information that can help in predicting future events. The reference dimension is concerned with the type(More)
This paper is concerned with the application of context -aware computing to museums and art galleries. The paper reports three studies addressing this issue. The first study involved a survey of visitors to an art gallery and focused on visitor activity and information requirements. This led to the conclusion that one could define visitor types and relate(More)
C4i is defined as the management infrastructure needed for the execution of a common goal supported by multiple agents in multiple locations and technology. In order to extract data from complex and diverse C4i scenarios a descriptive methodology called Event Analysis for Systemic Teamwork (EAST) has been developed. With over 90 existing ergonomics(More)
