Abstract

A described computer network includes a first computer system and a second computer system. The first computer system transmits screen image information and corresponding speech information to the second computer system. The screen image information includes information corresponding to a screen image intended for display within the first computer system. The speech information conveys a verbal description of the screen image. When the screen image includes one or more objects (e.g., menus, dialog boxes, icons, and the like) having corresponding semantic information, the speech information includes the corresponding semantic information. The second computer system responds to the speech information by producing an output (e.g., human speech via an audio output device, a tactile output via a Braille output device, and the like). The semantic information conveyed by the output allows a visually-impaired user of the second computer system to know intended purposes of the objects. The second computer system may also receive user input, generate an input signal corresponding to the user input, and transmit the input signal to the first computer system. The first computer system may respond to the input signal by updating the screen image. The semantic information conveyed by the output enables the visually-impaired user to properly interact with the first computer system.
