Sleep deprivation is known to have serious deleterious effects on executive functioning and job performance. Augmented reality has an ability to place pertinent information at the fore, guiding visual focus and reducing instructional complexity. This paper presents a study to explore how spatial augmented reality instructions impact procedural task performance on sleep deprived users. The user study...
Augmented reality systems commonly employ overt cueing to direct a user's attention and guide their actions. Spatial augmented reality based supraliminal annotations have been shown to improve user performance compared to LCD screens. This paper explores subliminal cues: annotations that exist below the threshold of consciousness. We investigate whether subliminal cueing is technically possible with...
This paper presents a proposal for the use of Spatial Augmented Reality as a tool for 3D data visualizations. The use of traditional display technologies such as LCD monitors provides a fish tank metaphor for the user, i.e. the information is behind a plane of glass. The use of VR technologies allows the user to be immersed in the 3D volume and remove this fish tank problem, but can limit the set...
