US Patent 10423237 Gesture-based control and usage of video relay service communications

A method and system are disclosed for enabling members of the deaf, hard of hearing, or speech-impaired (D-HOH-SI) community to start and control communications conducted through a video relay service (VRS) without the need for a remote-control device. A combination of standard-ASL and non-ASL hand commands are interpreted using “hand recognition” (similar to “face recognition”) to control the operation of a VRS system through multiple operating modes. The “hand recognition” process employs a camera/codec connected to a CPU which executes commands which may be stored in a non-volatile computer-readable storage device.
