Prediction of visually perceived location using reaching action and effect of reaching distance on it

We examined what effect the reaching distance had on the prediction of a visually perceived location using reaching action. A system presenting a virtual object must execute the process of interaction when a body is directly at the visually perceived location of the virtual object to enable direct interaction between an observer's body and the virtual object. Conventional techniques assume that the visually perceived location is the same as the location defined by binocular disparity. However, both locations are often different. We proposed a new technique in our previous studies to predict the visually perceived location using an observer's action. We also demonstrated prediction using an action where an observer reached out to a virtual object. This study was an examination into the range of applications of our proposed approach. An observer in an experiment reached out to a virtual object, and the reaching distance was the experimental variable. The results did not support the effect of the reaching distance on prediction. We demonstrated that our technique could be applied to a wide range of reaching distances.
