Abstract:     A motorized wheel-chair is equipped with one or more sensors for detecting obstacles. The detection method may be either radar or sonar (or both). An on-board computer processes these echoes and presents a visual or auditory display. With the benefit of these displays, the user issues voice commands (or exerts manual pressure) to maneuver appropriately the motorized wheelchair. One or more microphones pick up the sounds of the user's voice and transmit them to a computer. The computer decodes the maneuvering commands by speech-recognition techniques and transmits these commands to the wheelchair to effect the desired motion. In addition to speech recognition for decoding commands, voice (speaker) recognition is employed to determine authorized users.

First Claim:
Show all 7 claims
Having thus described our invention, what we claim as new and desire to secure by Letters Patent is as follows:     1. A motorized wheelchair for a user with severely limited mobility and with auditory and/or visual deficits comprising:
  • sensing means mounted on the wheelchair for detecting obstacles and generating an output signal indicating a distance, a size and a direction of a detected obstacle;
  • a first computer responsive to the output signal of the sensing means for processing the signal to generate visual and auditory displays;
  • a visual and auditory display device responsive to the first computer for providing the user with a warning, the distance size, and direction of an obstacle;
  • a microphone mounted on the wheelchair for generating signals in response to the user's voice commands based on signals from the visual and auditory display device; and
  • a second computer responsive to the microphone generated signals for processing the signals using a speech recognition program, the second computer generating output control signals to the wheelchair in response to recognized commands from the user.
