A Study on Perception and Operation Using Free Form Projection Display
A Free Form Projection Display using a distortion-eliminating algorithm was constructed. In the system, an object in the curved surface is used and the virtual object is represented by image projection. The virtual object is shown as if it fixed in the curved screen surface and gives the user a sense of motion parallax. Using this construction, the virtual object can be handled directly by the user’s hand and examined.
This system seems to be effective in manual operation and shape recognition of virtual object.
In order to evaluate the effectivity, we performed the experiments to compare FFPD and conventional flat display monitor with mouse from the viewpoint of depth perception and manual operation.
