• A Web-Based Intelligibility Evaluation of Sign Language Video Transmitted at Low Frame Rates and Bitrates

  Jessica J. Tran, Rafael Rodriguez, Eve A. Riskin, Jacob O. Wobbrock (2013) — Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper evaluates the perceived lower limits of intelligible sign language video for mobile communication, testing how much video quality can be sacrificed while maintaining comprehensibility for ASL users. The ITU-T recommends sign language video…
