Evaluation of 360o vision interfaces while performing spatial task under timed conditionAuthors: Anirudh Ravipati,Ambika Shahu Conference: The 16th IFIP TC.13 International Conference on Human-Computer Interaction - INTERACT 2017 Location Mumbai, India Date: 2017-09-25 Report no: IIIT/TR/2017/125 AbstractThe current study aims to evaluate the efficacy and efficiency of desktop 360o display designs, specifically navigation and direction judgment in an unknown environment. Based on previous studies, which showed an advantage of gaming experience on spatial abilities, we further tested the gaming experience and its relationship with speed of understanding space by varying the visibility of timer on screen. We conducted an eye-tracking experiment with three factors: interface type, gaming and timer visibility as mixed-group design. Participants were divided based on their gaming experience(gamers vs. non gamers) as well as timer visible condition(timer vs. no-timer). This resulted in four different groups of participants. The results show a significant effect of timer on the angle estimation across the three interfaces. Further, we found that gamers did outperformed non-gamers in angle estimation and total time taken to complete the task. Eye tracker data with twelve selected participants showed, comparatively lesser ‘fixation counts’ in left AOIs across all 360o display designs indicating the preferences in visual field. Further, the panoramic (360x1) interface showed longer time to first fixation suggesting either more exploration is required before making decision or too big FOV to scan to make the decision. The current results favors the 360o displays ”with visual boundaries” compared to the display ”with out visual boundaries” independent of the previous experience (gaming) or speed of processing (timer visibility).
