Enhancing Vision

This project aims to evaluate the effect of 360 degree display designs on constructing as real as possible local area and local situational awareness around the remote unmanned vehicle or robot.

More specifically the project has two major goals:

  1. Evaluate the effect of 360 degree display designs on constructing remote local area awareness - funded by CSRI, DST from April 2016 - March 2019.
  2. Assess Soldiers’ Cognitive and Ergonomic Profile and develop intervention protocols for effective training to use the optimal 360 degree user-interface- funded by INMAS, DRDO, from July 2016 - March 2019.

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.
