The purpose of this study was to find out which one is more effective between robot- and computer-based intervention on learning action word symbols of AAC. In detail, robot-based intervention utilized humanoid robot and computer-based intervention utilized laptop. Experimental questions are as follows: 1) Are there any differences between the effect of robot and computer on learning action word symbols of AAC for autism? 2) Will the effect of learning action word symbols of AAC generalize from individual words to words in story context?
Three preschoolers with autism participated in this study. This study used a single subject alternating treatments design to compare the effect of robot and computer on learning action word symbols of AAC. 20 symbols of action words in ‘Korean Ewha-AAC symbols set were selected and divided into two groups which are Set A and Set B. Symbols of Set A and Set B were exposed through robot and computer. To evaluate the understanding of action word symbols, each correct response about graphic symbol was scored as 1 point and each incorrect response was scored as 0 point. The result of this research showed that both robot and computer were effective on learning action word symbols of AAC, although there are some variability between subjects. By comparison, the robot was more effective than computer on learning action word symbols of AAC. Also the robot was more effective in generalization of learning on action word symbols of AAC from individual words to words in story context.
