People with dementia living in Long-term Care (LTC) are gradually experiencing diminished functional abilities caused by this brain disease. The declined cognitive functioning, decreased mobility, loss of memory and inner motivation provides inevitable challenges in engaging this group in activities. Lack of engagement are associated with disruptive behavioral and psychological symptoms of dementia (BPSD) such as agitation, wondering, apathy, passivity and depression. With no known cure in sight, developing and evaluating meaningful activities that foster and sustain engagement is critical for promoting quality of life for seniors with dementia in LTC.



Within dementia study, researchers find that one promising way to effectively achieve enhanced engagement is to actively engage people with dementia in activities that can still stimulate their remaining functions. Multi-sensory stimulation provides senses stimulation (visual, audio, tactile, olfaction and taste) without the need for complex reasoning, therefore are ideally for any stages of people with dementia.

Interactive Systems for Seniors with Dementia in Long-term Care are derived from interdisciplinary research between Occupational Therapies and Design. The project aims to engage people with dementia in designed meaningful activities, in order to achieve enhanced engagement and reduced behavioral and psychological symptoms of dementia. It investigates how multi-sensory stimulation and levelled interactivity within interactive system influence users’ engagement while interacting.

An interactive installation CtN was developed and built in the public hallway of Vitalis for on-site user testing and research development. The original design aims to connect residents with outdoor life through an indoor interactive experience, due to their limited access to real nature.

It shows relaxing farm scenery from a Dutch child farm displayed by a high definition screen. A physical old-time style water pump that pumps real water into the water trough was built for interacting purpose and sensory enhancement. When the system detects a resident is interacting with the pump, it sends a video feed of animals being fed.
