Abstract/Summary

INTRODUCTION: Accessibility options within apps can enable customisation and improve usability. This study set out to examine whether the introduction of accessibility settings for people with dementia in touchscreen apps could improve the user experience. METHODS: Thirty participants were recruited to play on three occasions, one of two apps adapted with the inclusion of accessibility features derived from an analysis of gameplay in a previous study. The results were compared with those from the earlier study (i.e. pre-adapted apps). RESULTS: The accessibility features significantly improved usability in the previously more difficult app (Solitaire) and maintained playability with marginal improvements in the previously more accessible app (Bubble Explode). DISCUSSION: This first study of implementing accessibility settings for dementia in mainstream apps demonstrate their feasibility and impact. The findings reveal core principles of touchscreen interaction and design for dementia that can inform future app development.
