The Research of Visual Characteristics for the Deaf Wearing AR Glasses

In order to design AR (Augmented Reality) glasses for the deaf, this paper studies the virtual display interface of AR glasses. It is found that 89.8% of the deaf have willingness to use AR glasses based on questionnaires of 1900 deaf people. An experiment with 10 deaf subjects and 10 hearing subjects was done to calculate times of completing specific tasks. The results show that: (1) 80% of the deaf subjects have 3 to 5 zones in the interface with significant differences on cognitive efficiency, compared with the 6 to 7 zones from 80% of the hearing subjects. (2) The heat maps of the cognitive efficiency distribution shows that there is an obvious difference on the distribution patterns of regional sensitivity between the two groups. (3) The significant difference on cognitive efficiency of the deaf shown in different display zones is less than that of hearing people.
