| Description | In one of the sensory characteristics database of elderly persons and persons with disabilities, it is a database that can estimate the legible font size of a letter and a digit by setting design parameters of the display character (font, characters, and luminance contrast between a character and background) and their conditions of use (user’s age and viewing distance). In addition, this database can estimate the legible luminance contrast between a character and background by setting design parameters of the display characters (font, characters, and size) and their conditions of use. |
