Project Goal

Aiming to enrich the positive multi-sensory experience of people with dementia who need a sensory focused activity with the co-designed textile-based sensory tool.

The Growth in Numbers of People with Dementia

The prevalence rates of dementia in Hong Kong is estimated to be at 5%~8% among persons aged over 65, and at 20%~30% among those aged over 80.

Benefits of Stimulating Multi-senses

“Stimulation and activity suitable and appropriate for the individual with dementia will help keep the person active and included which also helps both to maintain function and cognition, and to manage and moderate mood and behaviour.”

Interviews in Dementia Community

I conducted the group interviews and rapid ideation workshop with the social workers, occupational therapist and care director to understand the current status of the elderly community centre and their expectations to improve the service. I also had informal interviews with family members and informal caregivers in the dementia community. Throughout these activities, I was able to extract the stakeholder's map of the centre and personas.

"We normally use the child toys to lead the cognitive training activity for the clients with dementia because of lack of time and skills to make activity tools professionally."

User Journey of Social workers to Provide the Dementia Activity Service

Throughout the interview with the social workers, I understand the user journey of providing dementia activity services at the elderly community centre.

To understand their existing dementia activities at the centre, I attended their activity sessions. I observed how to communicate with people with dementia and how the dementia activity influence on dementia community, including a focus group with dementia, informal caregivers and family members.



I conducted the colour and material preference survey with focus groups with dementia to understand 

their preferred colour and materials. I designed the survey that people with dementia who have cognitive impairment a straightforward way of engaging.


How might we help more people with dementia to have the benefits of cognitive training activity as well as multi-sensory stimulation?

User Scenario with Sensory Wall

The first function of the Sensory Wall embedded an infrared sensor into each wall panel to sense users by the wall panel, and it illuminated each time a user passes by. In the second interactive function, touching a specific part of the wall panel would trigger the touch sensor, and the board reacted with sound and illumination.
