MobileASL: Intelligibility of Sign Language Video as Constrained by Mobile Phone Technology
This paper presents MobileASL, a video compression research project aimed at enabling Deaf people to communicate in American Sign Language (ASL) over mobile phone networks. In 2006, Deaf people in the US were limited to text messaging on mobile phone…

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

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

Evaluating Intelligibility and Battery Drain of Mobile Sign Language Video Transmitted at Low Frame Rates and Bit Rates
This paper investigates the lower limits of intelligible sign language video on mobile devices, seeking to determine the minimum frame rate and bit rate that still allow deaf users to understand ASL video conversations. Mobile video communication is …
