“…Expanding on this, another study conducted under controlled conditions developed a new reminder system for people with dementia which primarily used a Virtual Agent user interface – i.e. a “chat bot” or simulated person who conversed with the person with dementia – as well as a touch screen graphical user interface (Tokunaga et al, 2016). The device was trialled with 17 hospital patients with dementia and their carers, and the study found that participants could use it and interact with the Virtual Agent, at least to some degree (Tokunaga et al, 2016).…”

However, this study did not assess the usefulness of the device for prospective memory, evaluate outcomes for users, or trial its usefulness in home environments.…”

This paper details a review of the literature on the use of electronic aids for prospective memory for people with dementia. Key findings of the review are that: electronic memory aids show potential for supporting people's prospective memory but the devices and software applications need further development in order to function reliably; sample sizes of studies are often very small, limiting the generalisability of their findings; few studies of devices are conducted in users' home environments; and most of the studies focus on the effectiveness of the electronic memory aid, rather than outcomes for users, such as improved daily functioning, quality of life, or social connectedness. The review concludes that future studies with robust devices are required that explicitly focus on the varying needs and capacities of people with dementia, in order to generate additional evidence for the effectiveness of electronic memory aids for this cohort.

“…In 4 studies, the user could only give yes or no or a few other short commands [ 24 , 33 , 34 , 40 ]. The user verbal command options in the studies by Tokunaga et al [ 19 , 32 ] were unclear. Only the studies by Ali et al [ 30 ] and Razavi et al [ 31 ] report a short (3-5 turns) open dialogue on a range of topics such as weather, pets, retirement, life goals, growing older, and spirituality.…”

“…Wargnier et al [ 24 ] and Tsiourti et al [ 33 ] did not use existing usability questionnaires from the literature, such as the System Usability Scale, but created new usability questionnaires. The studies by Tokunaga et al [ 19 , 32 ] were more oriented toward the functional performance of the agent, whereas Oliveira et al [ 35 ] did not report clear usability measurement methods and results. A comparison between the usabilities is difficult to make because of the difference in the methods and scales used.…”

Voice-Enabled Intelligent Virtual Agents for People With Amnesia: Systematic Review

et al. 2022

View full text Add to dashboard Cite

Background Older adults often have increasing memory problems (amnesia), and approximately 50 million people worldwide have dementia. This syndrome gradually affects a patient over a period of 10-20 years. Intelligent virtual agents may support people with amnesia. Objective This study aims to identify state-of-the-art experimental studies with virtual agents on a screen capable of verbal dialogues with a target group of older adults with amnesia. Methods We conducted a systematic search of PubMed, SCOPUS, Microsoft Academic, Google Scholar, Web of Science, and CrossRef on virtual agent and amnesia on papers that describe such experiments. Search criteria were ( Virtual Agent OR Virtual Assistant OR Virtual Human OR Conversational Agent OR Virtual Coach OR Chatbot ) AND ( Amnesia OR Dementia OR Alzheimer OR Mild Cognitive Impairment ). Risk of bias was evaluated using the QualSyst tool (University of Alberta), which scores 14 study quality items. Eligible studies are reported in a table including country, study design type, target sample size, controls, study aims, experiment population, intervention details, results, and an image of the agent. Results A total of 8 studies was included in this meta-analysis. The average number of participants in the studies was 20 (SD 12). The verbal interactions were generally short. The usability was generally reported to be positive. The human utterance was seen in 7 (88%) out of 8 studies based on short words or phrases that were predefined in the agent’s speech recognition algorithm. The average study quality score was 0.69 (SD 0.08) on a scale of 0 to 1. Conclusions The number of experimental studies on talking about virtual agents that support people with memory problems is still small. The details on the verbal interaction are limited, which makes it difficult to assess the quality of the interaction and the possible effects of confounding parameters. In addition, the derivation of the aggregated data was difficult. Further research with extended and prolonged dialogues is required.
