Usability of a touchscreen assessment tool (TATOO) prototype for clinicians and typically developing children.

The TATOO is a user-friendly tool. Researchers and clinicians can benefit from the availability of an objective and low-cost assessment tool to promote their evaluation and intervention by providing more focussed individualized recommendations and adaptations. The study also suggests a model to follow when developing applications and evaluating their usability through a mixed-method approach to deepen understanding of the user's needs.Implications for rehabilitationTouchscreen Assessment Tool (TATOO) shows a user-friendly tool for assessing the different skills required to operate touchscreens interface.TATOO has the potential to become an essential objective and low-cost assessment tool for the clinician, in which the spread of touchscreens constantly increases.Researchers and clinicians can benefit from the availability of such tools to promote their evaluation and intervention by providing more focussed individualized recommendations and adaptations.TATOO will complement the assessment needs, as traditional fine motor assessment tools cannot capture the skills necessary to operate a touchscreen deviceThe study suggests a model to follow when developing applications and evaluating their usability through a mixed-method approach in order to deepen understanding of the user's needs.
