Background

In usability testing, evaluators often face uncertainty as to whether they have collected sufficient user data to identify any underlying problems. Because, some users may not fully engage in the testing process, and the recruited user group may not be representative of the intended user population. In this research, we propose a novel approach to address these challenges by utilizing tracked user interactions to assess the "task coverage" performed during usability testing, thus enabling more reliable and comprehensive testing results.

Background

The immersive nature of VR often results in decreased eye blink and movement, putting users at risk of developing conditions such as dry eye syndrome and eye strain. In this research, we propose visual techniques to induce temporary eye blinks or movements by drawing users' attention temporarily, to mitigate the negative effect of VR on eye health.
