P4‐149: EVALUATING THE EFFECT OF GROUP MOTION‐BASED TECHNOLOGY ON MOVEMENT CONFIDENCE AND BALANCE IN PEOPLE WITH DEMENTIA, MILD COGNITIVE IMPAIRMENT AND PHYSICAL IMPAIRMENT

independence. Households were given the devices for ten weeks, and then a follow up interview was carried out and all ‘Alexa interactions’ (Figure 2) were mined from Amazon using the ESCAPE protocol [1]. Results:We observed from qualitative interview data that the Amazon Echo was generally well received and that it facilitated independence for participants. Contrary to our initial hypothesis, independence was in the majority facilitated by the entertainment functionality more than the practical task-related features of the device. Using the Echo devices as a method of data collection proved to be highly successful, with an average of over 3000 recordings per household (Figure 1). These data support findings from the qualitative interviews about how the devices were used (Figure 2). These data also highlight groupwise differences between the PCA and control groups, for example the PCA group was significantly more likely to repeat the wake word when using the devices (p< 0.034, U1⁄424877238). Conclusions: For this group of people with PCA the Amazon Echo facilitated independence overall. The Echo is also a useful device for collecting large, rich datasets from people with dementia in a naturalistic setting. We hope that findings from this proof of concept trial can inform further research into voice-assistive technologies for people with dementia. Reference: Firth et al, arXiv:1706.06176 [cs.HC.
