Abstract

The research project on the development of a three-dimensional sign language metahuman technology in online learning media for hearing-impaired students aimed to study and compare the learning outcomes of online lessons using a human sign language interpreter and a three-dimensional sign language metahuman that used Inertial Sensor Modules technology and to measure the satisfaction of hearing-impaired students towards the use of a three-dimensional sign language metahuman in online lessons. The research findings were as follows: 1. Comparing the learning outcomes of both groups of students through pretests and post-tests, the scores from using the three-dimensional metahuman showed that the average post-test score was higher than the pre-test score. The scores from using a real person as an interpreter showed that the average post-test score was lower than the pre-test score. 2. Comparing the learning outcomes of students in the same group using Wilcoxon Signed Rank Test, it was found that the learning outcomes of students from using a human interpreter did not differ and the learning outcomes of students from using a three-dimensional metahuman differed with higher scores, but not statistically significant. 3. Comparing the learning outcomes of students between groups using MannWhitney statistics, it was found that the median of the pre-test scores of the students in the group that used a human interpreter and the group that used a three-dimensional metahuman differed, but not statistically significant. 4. The results from the satisfaction evaluation showed that the respondents had more satisfaction towards the human interpreter than the three-dimensional avatar in every aspect, except for the aspect of clear and easy-to-understand sign language expression, which the satisfaction of the three-dimensional metahuman was higher than the human interpreter.
