Effect of different 360-degree display user-interface on spatial awareness, more specifically object-to-object (allo-centric representation) and object-to-observer (ego-centric representation)

The above figures depict , three display designs and corresponding results. Three Interfaces used in the study from left to right: a. 90x1 Interface with the front 90-degree view only., b. 90x4 Interface consisted of 4 views each covering 90-degree view (from top clockwise, left, front, right and rear view around the UGV)., c. 180x2 Interface with 2 views each covering 180degree (the top view is front 180-degree and below is 180-degree behind the UGV).

We used multiple measures to evaluate the effect of three different 360-degree user-interfaces on ease of spatial understanding by measuring their exploration duration (time taken to complete the exploration), their spatial knowledge about the explored environment by employing survey on perspective taking tasks and object-object relationship. The trends indicated an advantage for 180x2 display designs compared to the other 360-degree UI designs.

360-degree Vision: Eye-tracking while exploring different User-Interfaces

The images depict the trends in eye-movement while interacting with two different user-interfaces to display the 360-degree field of view.

Path Logging while exploring 360-degree

The figure is depicting the layout and area of interests in a given 2D virtual environment. In addition, the two navigational walk through across Male and Female Sex, that were used while exploration.
