• Evaluating Quality and Comprehension of Real-Time Sign Language Video on Mobile Phones

  Jessica J. Tran, Joy Kim, Jaehong Chon, Eve A. Riskin, Richard E. Ladner, Jacob O. Wobbrock · 2011 · Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2011)

  This paper investigates the relationship between objective video quality metrics (PSNR — peak signal-to-noise ratio), subjective quality preferences, and actual comprehension of American Sign Language (ASL) video transmitted at very low bitrates on mobile phones. At the time of…
