“…The visual ability to focus and to converge are popular parameters for providing proper stereoscopic vision. It is important to design HMD optics with less discrepancy to focus and for convergence [16] [18]. Therefore, the HMD focal length is usually designed approximately 1 m from the view position.…”

“…It is important to consider latency as well as frequency width to be able to reproduce a user's head movement. Watanabe et al constructed a six DoF robot head designed with a minimum of weight [18]. As a result, the robot head achieves much less latency and wide frequency width when realizing a user's voluntary head behavior.…”

“…The pupillary distance is 65 mm. This setup is similar to the previous research [18]. A black soft form shield is attached to the HMD to cover all peripheral areas of the lens so that participants cannot see their hand even when looking down.…”

“…To obtain FPV, we use a robot camera head. The robot head called TORSO has two small binocular cameras at a regular pupillary distance of 65 mm, which is 7 mm in diameter [18]. The horizontal FOV is 46 degrees and its resolution is 768 × 494 pixels.…”

“…The visual transfer system TORSO [18] is placed 1 m behind the participants to provide visual feedback when they look at themselves from behind. This distance was determined based on several factors: the HMD FOV, the distance of the virtual screen, and the length of the stick.…”

Rubber Hand Illusion (RHI) is known to provide a proprioceptive drift toward the direction where the rubber hand is tapped. On the other hand, Out-of-Body Experiences (OBEs) induce an entire body shift from a third-person Point of View (PoV) . These experiences are known to trigger external passive tactile cues. Telexistence allows an entire body shift from a first-person PoV, compared to RHI and OBE. However, the precise origin of the entire localization is not revealed when we actively provide the internal voluntary tactile cue. Therefore, in this paper, we focus on the effects of tactile cues to determine self-localization during the action of self-tapping. Participants viewed and tapped their own body on the back, and evaluated where on their body they perceived the tapping. The experiments show that the localized position tends to shift forward when an individual is tapped by a third-person; in contrast, the localized position tends to shift backward when an individual is tapping his own back. The subjective report indicates that participants perceived themselves as leaving their own bodies, or that someone appeared in front of them suddenly. Thus, we consider that self-produced tactile cue induces telexistence experience.
