An optical illusion phenomenon is used in order to represent the three-dimensional world on two-dimensions of screens in Human Computer Interaction. As for the presentation of depth information represented by "Aero Glass" on Microsoft Vista and the compartment of the information presentation domain that used closed figure (Window), an optical illusion phenomenon about depth perception was used.
Hydet, et al. (1984) suggested that similar reaction in the brain was evoked by subjective contour when an outline shown physically was presented. It was suggested that the subjective contour line was effective as reference line of an point of subjective equality (PSE) judgement in evaluation of length (Takahashi, 2007). In this study, re-cognition performance of the figure which was generated by brightness illusion was examined experimentally.
As a result, as a quantity of a brightness illusion increased, it was suggested that re-cognition performance of visually presented illusory figures deteriorated. In addition, it was suggested that re-cognition performance was low at an amodal figure in comparison with a modal figure.
Therefore, it is important that the reduction a quantity of brightness illusion caused by a figure element is needed in order to improve by re-cognition performance.
