Outline of Final Research Achievements

We have develop a design method for the design of an environmentally reflective mid-air image method. Specifically, in designing environmentally reflective mid-air images, we can design what kind of reflective glossy material can be used to display mid-air images with what brightness and blurriness, and how easy the images are to see. Using the optical properties of the reflective surface, we worked on and verified three mid-air image methods with respect to the representation of blurring and one with respect to the calculation of luminance. As a result, we succeeded in obtaining a PSF-like relation that shows a non-anisotropic spread from the line spread function that expresses the blurring, and in expressing the blurring of an environmentally-reflective mid-air image, and in estimating the luminance by calculating the gloss, which is one of the characteristics of the reflective surface.
