Virtual reality learning software for individuals with intellectual disabilities: comparison between touchscreen and mouse interactions

The aim of this article is to analyze the impact of two user interfaces a tactile interface and a computer mouse on a virtual environment allowing self-learning tasks as dishwashing by workers with mental deficiencies. We carried out an experiment within the context of a design project named “Apticap”. The methods used were an experiment, an identification questionnaire and a post-experimentation interview, with six disabled workers. The results of this study demonstrate the interest of a virtual reality tool associated with a tactile interaction for learning of real tasks by workers with mental deficiencies.
