A Study on Visualization of Discussions in Group Work with Students with Hearing Disability and without Hearing Disability in Higher Education

Abstract

We propose a software to visualize the discussion in a group work with students with and without hearing disability. The interview survey revealed the following issues in traditional information support methods in group work: 1) simultaneity of information, 2) increase in the volume of voice information, and 3) mobility of equipment. From the testing of the developed software, it was revealed that the cognitive load of students with hearing disability could be reduced by color-coding each speaker, although the time lag in the discussion could not be eliminated.
