Resumo
With this study we aim to assess if the touch screen input device can be a more usable option for digital interaction by
people with intellectual disabilities, when compared to a traditional mouse input. In previous studies, we observed that
many users with intellectual disabilities struggle to interact with digital content when using traditional input devices, such
as the keyboard or mouse. This can lead to a decrease in their motivation to access digital content. Therefore, it is
important to evaluate other options, such as touch screens, in order to present a more usable option of interaction for this
specific group. For that, we present a case study where the participants were invited to perform primitive selection tasks
in a colouring activity, using a painting Web application. The results showed that this group presented a better
performance and made less errors when interacting with the touch screen, rather than when compared with the traditional
mouse input. We also registered an increase regarding their motivation and satisfaction, when using the touch screen as
the input device.
