Implementing Accessibility Settings in Touchscreen Apps for People Living with Dementia
Open accessAbstract
Background: Accessibility options within apps can enable customisation and improve usability. The consideration of accessibility for people living with dementia has not been explored but is necessary to prevent a “digital divide” in our society. This study set out to examine whether the introduction of accessibility settings for people with dementia in two mainstream gaming apps (Solitaire and Bubble Explode) could improve the user experience. Objectives: To evaluate the effectiveness of tailored accessibility settings for people living with dementia by comparing the gameplay experience with and without the settings and measure the impact on their ability to initiate gameplay, play independently and experience enjoyment. Methods: Thirty participants were recruited to test one of the two apps that had been adapted to include accessibility features. These features were derived from an analysis of gameplay in a previous study, from which the design of the present study was replicated. The results were compared with those from the earlier study (i.e., pre-adapted apps). Results: The accessibility features significantly improved usability in Solitaire, which had been the more problematic of the two apps when evaluated in its pre-adapted form. Bubble Explode retained the high level of usability without further improvements. Initiation of gameplay was significantly improved in the adapted version of Solitaire, with no significant differences to progression or enjoyment for either app. Conclusions: This study represents the first implementation of accessibility settings for dementia in mainstream apps, whilst demonstrating the feasibility and positive impact of the approach. The findings reveal core principles of touchscreen interaction and design for dementia that can inform future app development.

“Compared with surveys, this usage data is especially suited to detect problems and evaluate the status quo [23].”
The quality of automatic speech recognition and synthesis is still a technical issue and has room for improvement, whereas touch screen modality is almost stable and positively used by people living with dementia.
“Unfortunately, our study confirms that the quality of automatic speech recognition and synthesis is still a technical issue and has room for improvement [7-11], whereas touch screen modality is almost stable and positively used by people living with dementia [3,25,26].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
