Optimizing the information transfer of near-eye displays
Abstract
Near-eye displays (such as Head-Mounted Displays or HMDs) are increasingly replacing head-down displays for information display. However, the amount of information on a head-mounted near-eye display is significantly limited by crowding or visual clutter: the inability to resolve visual details in the presence of other (flanking) visual elements. Color, polarity, temporal asynchronicity and 3D stereo have been identified as promising features that can be used to counter this effect, i.e. to ‘declutter’ the display. The addition of these features to a near-eye display may therefore enhance the amount of information that can instantaneously be perceived. In the proposed study we will compare the effectiveness of these different features to declutter HMD symbology. Specifically, we will investigate to what extent the addition of color, polarity, temporal asynchronicity and 3D stereo to display symbology can increase the amount of useful information that can be perceived on a near-eye display. By varying experimental parameters like information density, task duration, and display FOV the proposed study will provide information about (1) the information an operator can take in via a near-eye display, (2) the largest ‘useful FOV’ for an average operator, and (3) the value of orthoptic screening under stressful conditions, i.e. the degree to which the useful FOV varies among individuals. The results of the proposed study will be used to construct a model that computes an upper limit for the amount of useful information that a user can take in for a given combination of FOV, detail (e.g., letter) size, color, polarity and viewing conditions (stereo/mono). Such a model will be useful for the design and evaluation of near-eye information display systems.
