The Effects of Reintroducing Haptic Feedback to Virtual Reality Systems on Movement Profiles When Reaching to Virtual Targets

Chapter


Abstract


  • Virtual reality (VR) has been shown to have significant impacts on the

    efficacy of rehabilitation, improving a patient’s motivation and

    participation, as well as improving scores in functional assessments when

    used to enhance traditional therapy. However, movements in VR have

    been demonstrated to have significant differences in movement profiles

    whilst performing simple reaching tasks compared to their real

    counterparts. The lack of tactile perception in VR systems is often

    attributed to be one of the causes of these differences. Therefore, to

    investigate the degree to which the lack of haptic feedback impacts

    movement profiles in VR, we have reintroduced the sense of touch

    through vibration motors on the fingertips. Participants were required to

    reach to virtual targets, both with and without haptic feedback. Their

    movements were quantified using motion capture, and the virtual targets

    were rendered using the Oculus Rift. The motions to both targets were

    compared using a number of measures to characterize the velocity

    profiles. Preliminary results suggest that the reintroduction of haptic

    feedback improves performance based indicators in virtual reaching

    tasks, such as the time to complete a reach, and the stability of the

    reaching hand whilst touching the virtual target.
