FIGURE 1.

The participant’s view from the HMD. (A) For both groups, a gender-matched virtual body was seen from 1PP with the same posture with the real body, as if they were spatially coincident. Participants were asked to look around and describe what they see (1 min). (B) For both groups, a virtual ball touched the right virtual hand various times while the real hand was physically touched at the same timings (2 min). (C) For the amputation group, part of the right virtual arm disappeared, as if amputated (3 min). (D) Following, the virtual ball touched the area previously occupied by the right virtual hand and part of the forearm (i.e., the table surface) without triggering any physical touch to the participant’s right hand (10 min).
