This study evaluates the usefulness and efficacy of three different continuous input devices - Makey Makey, Tobii Eye Tracker 4C, and Leap Motion - in promoting computer engagement for people with disabilities. A preliminary pilot study was conducted with the participation of one person with several disabilities. They were given various tasks to accomplish using each continuous input device, and their performance was assessed. To conduct the study, an experimental environment including two computers and a designed interface had to be setup. The findings showed that Leap Motion had poor perceived usability and that Makey Makey had the best usability, followed by Tobii Eye Tracker 4C. The pilot study also emphasizes the difficulties and modifications needed for people with disabilities to use these input devices in an efficient manner. These results highlight how crucial it is to create inclusive interfaces and technologies in order to improve accessibility for a range of user demographics
