Abstract


  • Visually induced illusory self-motion (vection) was facilitated by active breaststroke arm and body

    movements. Optic flow was generated by having the standing observer make these arm movements,

    which were detected by Kinect and incorporated into the display. When generated, this optic flow

    was either expanding (i.e. congruent with the observer's head motion) or contracting (i.e. incongruent

    with his/her head motion). Optic flow generated during these active movement conditions was also

    later played back to the observer during passive viewing conditions. On each of these trials, we

    recorded vection strength (latency, duration and magnitude). We found that: (i) both congruent and

    incongruent breaststroke movements increased vection (i.e. compared to passive viewing conditions);

    and (ii) congruent breaststroke movements increased vection more than incongruent ones. We name

    the enhancement provided by this type of active movement 'virtual swimming'. This demonstration

    shows that even unusual body movements can function as a self-motion signal.
