“…Similar to the more comprehensive 'nighttime wandering system' of Radziszewski et al, that encouraged people with dementia to go back to bed in a soothing way with lighting and the use of media at night, we are interested in an interactive system that can be used during the day to gently steer people in an entertaining and playful way [28]. Nudging interventions (i.e.…”

Many nursing homes for dementia patients struggle with residents that wander towards the exit with the intention of leaving. Several types of interventions have been used to deal with this issue. Unfortunately, many of them are quite forceful, or are unsuitable for the specific context of certain nursing homes. In this paper, we investigate the possibility to using a more playful persuasive intervention. The design itself is in the form of a lost puppy, equipped with several actuators and sensors, that has to be brought 'home', in order to steer residents unknowingly away from the exit. Our first pilot indicated that residents noticed the puppy and showed interest in the device, and might be distracted from the exit. However, the puppy in its current form did not yet lead the residents away from the exit. Based on our contextual analyses, related work, and received feedback, we share our design insights which could be helpful for creating playful interventions for people with dementia.

“…Boumpa et al 10 propose a system that provides audio cues for a PWD to help them identify a familiar visitor, but the system has not been field tested. Finally, Radziszewski et al 11 describe a custom-assembled system that operates in two phases: two weeks of "analyzing" night-time behavior, followed by an "assistive phase" that is purported to decrease the stress associated with wandering. They suggest the system was field tested but do not provide clinical results.…”

Introduction More than half of persons with dementia will experience night-time wandering, increasing their risk of falls and unattended home exits. This is a major predictor of caregiver burnout and one of the major causes of early institutionalization. Methods Using smart home technologies such as sensors, smart bulbs, pressure mats and speakers, the Night-time Wandering Detection and Diversion system is designed to assist caregivers and persons with dementia that are at risk of wandering at night. Being placed in homes around Ottawa for a 12-week trial, the system allows caregivers to rest peacefully in the night, as it detects when the person with dementia gets out of bed and automatically provides cue lighting to guide them safely to the washroom. The system also uses prerecorded audio prompts, if they venture from the bedroom, only waking the caregiver when the person with dementia opens an exit door. Results Thus far, the average depression and anxiety in caregivers have been improved after the 12 weeks, and most have said that they sleep more peacefully. Conclusion The system has proven successful in supporting the safety of persons with dementia as well as their caregivers.

Objectives: This work presents an ambient-assisted living application that encourages seniors during nocturnal wandering episodes to return to bed in calm and comfort reassurance. Methods: Structuring knowledge by designing a software architecture capable of delivering high-level analysis and processing. A senior's home has been upgraded into a smart home enabling the gathering of habits for two weeks and set up for personalized assistance over four weeks. Home automation devices associated with Actigraph monitors and self-reported sleep were used for more accuracy.Results: The architectural model can be used in ambient-assisted living applications for which data collection is permanent and continuous. Its layered organization facilitates the management of specific and general activities of daily life. The results of the home experience show that the system gave a notification whenever the need arose. On the other hand, it allowed the caregiver to get more information about the lifestyle of the senior. Conclusions: Future work should focus on providing more services to contextualize assistance. Ontology is used to structure all the ambient knowledge of the smart home. We also plan to do more home experiments.
