Recent research indicates that users consistently underestimate depth judgments to Augmented Reality (AR) graphics when viewed through optical see-through displays. However, to our knowledge, little work has examined how AR graphics may affect depth judgments of real world objects that have been overlaid or annotated with AR graphics. This study begins a preliminary analysis whether AR graphics have...
Haptic shared control is a powerful way of combining the best of humans and intelligent vehicles, keeping humans in the loop while avoiding many automation issues. Literature has shown that haptic shared control can support drivers to increase performance at reduced control effort, but also points out that even then, subtle conflicts occur between driver and shared controller. This paper hypothesizes...
This study describes how an algorithm was developed from a vision theory, so that the algorithm can quantify an amount of a specific type of eye movements, called saccadic intrusions. The second half of the paper describes the strong positive relationship between mental workload and saccadic intrusions. The results imply that the person's cognitive demand level can be accurately estimated from the...
Thirty participants who aged from 21 to 37 years old were recruited for this study and divided into two groups depending on driving license. The cognitrone, visual pursuit and tachistoscopic traffic tests were conducted by Vienna Test System. The total hits, total correct rejection and mean time were recorded in Cognitrone test. Further, forty items of visual pursuit test were performed and the scores,...
General Systems Performance Theory (GSPT) was initially motivated by problems associated with quantifying different aspects of human performance. It has proved to be invaluable for measurement development and understanding quantitative relationships between human subsystem capacities and performance in complex tasks. It is now desired to bring focus to the application of GSPT to modeling of cognitive...
Sixty-three participants who aged from 22 to 65 years old were recruited for this study and divided into three age stratifications. Assessment of participants' abilities and self-rating were conducted by tests of traffic regulations, visual abilities and digital type speed anticipation reaction. Results of MANOVA showed that self-rating scores, test scores of traffic regulations, visual acuity, depth...
The distribution of tasks and stimuli across multiple modalities has been proposed as a means to support multitasking in data-rich environments. In particular, the tactile channel and, more specifically, communication via the use of tactile/haptic icons have received considerable interest in recent years. Past research has examined primarily the impact of concurrent task modality on the effectiveness...
