KnowU social teleprompter: Interaction design applied to intervention therapy for language decline in early AD patients

Art therapy as an intervention has been shown to alleviate social impairment in people with AD. Meanwhile, digital technology (DTS) has been shown to perform well in different degenerative dementias through mobile devices and apps. However, it is unclear whether digital art creation therapy has an impact on the speech function of people with early AD. Therefore, the aim of this study was to confirm whether digital art creation therapy has an ameliorating effect on language decline in AD patients through the KnowU social teleprompter. This study was a controlled trial in which 16 patients with early AD worked with us and were divided into a paper-based art creation therapy group (control group) and a KnowU social teleprompter therapy group for a 6-week intervention. In the digital art creation intervention group we introduced the KnowU digital kit, consisting of a creation plug-in for the Procreate app on a tablet and a wearable device and its app. The entire treatment process is recorded and combined with a quantitative analysis of the McNemar $\chi$2 test to analyze the differences in outcomes of verbal communication function in early AD patients after different therapies. Ultimately, it is shown that early AD patients utilizing​ the KnowU social teleprompter are more effective in the intervention treatment of language decline in the real social domain compared to the paper-based art creation therapy group. The discussion further demonstrates that DTs and art therapy can provide a better social experience, creative approach and emotional recall of language loss in early AD patients, as well as increase the collaborative relationship between early AD patients and their caregivers.
