- Abstract
- Background A piece of visual information is recognized as a set of display codes through perception to the cognition cycle of a user. The overlapped meta-image on a transparent display and the background behind the screen increases the complexity of recognized information. Especially the rear-side users will experience the extra workload of left-right reversed information processing.
Methods The normal display code of images has been newly classified into four subcategories: text, geographical image, socio-symbolic image and spatially coded image. The different coded images were used to construct four sets of test screens in a combination of forward directed-reverse directed design. Users were then asked to perform the perception – cognition cycled information processing tasks with a designed screen on a transparent display.
Result The reversed visual information took longer time than the forward direction information for users to recognize. There was a difference amongst users’ cognitive sensitivity onto reverse images in the following order; text – geographical image - socio symbolic image and spatial coded Image. The socio-symbolic image and spatial coded image showed less sensitivity of direction compared to text and geographical images which decreased big performance gap when reversed.
Conclusions The source of reversed visual information problem on the rear side of transparent display UI was analyzed via context based display-coded images which indicated the different level of forwarded - reversed direction sensitivity when transferred to users. The result is applicable for the improvement of transparent display for better user experience on dual surface interaction.
