Dementia Design Research

Healthy Seating

How might we help elderly people who suffer from dementia with living a healthy life in their own home ?

Healthy Seating for the Elderly

This design project is aimed at enabling the elderly with dementia to live at home independently and safely for longer through a product which preserves the atmosphere of their home. Here, the focus is on improving their sitting posture, as people with dementia usually spend much time sitting, often without adapting their position to maintain a healthy and dynamic posture. This can influence their mental state, as physical discomfort and inactivity lead to restlessness.

The adaptive seating system is suitable for people in all stages of dementia and dynamically complies to the user’s needs. Through physical movements reacting to measurements of the current position, an active and healthy sitting posture is maintained. This product improves elderly’s physical and mental well-being, as well as relieving caregivers of the physically challenging task to adjust their posture manually allowing for more social contact.

Client & Stakeholders

Kempenlef was founded to solve societal problems occurring in “de Kempen”. The drastic aging of the population and the rising number of dementia cases is causing problems in the local community. Kempenlef sets out to solve the problems in healthcare. Healthy seating is one of many projects originating from Kempenlef.

 

The partners participating in these projects are; Summa College, RSZK, Simac, Eindhoven University of Technology, Rabobank, the municipalities of Bergeijk and Bladel and finally the corporation ‘Slimmer leven 2020’.

Case Study

As a part of several field interviews, one particular case needs to be highlighted since it offered a strong inspiration for the design direction that was chosen later on in the process. This case concerns a lady suffering from vascular dementia, a bad back (severe scoliosis) and impaired mobility.

 

She lives with her husband who cares for her all day and night. Although she enjoys answering the questions on her Pickwick tea and watching TV for distraction, she mostly sits in her chair all day which was a theme in more cases. She is, however, unable to remain in a healthy and comfortable upright position, when she falls asleep her upper body falls forward and her head hangs limply to the right. Her husband already bought a different chair, but since the lady keeps losing weight and does not change her seating posture, he has modified the chair with a large number of pillows. The husband cares so much for his wife but has not a moment of rest in the day, continuously needing to check if his wife is still alright in her chair.

This specific case makes all findings resulting from the different types of research altogether more personal which is why it was highlighted here.

From Research...

Findings from desk and field research were synthesized into one clear design case: creating healthy seating for elderly suffering from dementia. Series of brainstorms and exploratory sketching numerous solutions. The most promising combination of solutions were quickly brought to life with multiple prototypes which were tested and validated with real people suffering from dementia.

...To Prototype

The development led to a future proof concept that combines smart heath technologies with the everyday home environment. The seating area captures the users sitting posture and slowly shifts the position to vary the sitting posture over long periods of time. The data collected by the chair can be shared with caretakers and healthcare professionals to spot potential physical problems before they can reach a critical state.

Future Vision on Healthy Sitting

Based on our user tests with prototypes, we adjusted parts of our design and set up requirements for its further realization and implementation. A system of sensor measurements was used for measuring seniors’ posture, and data can be collected and visualized. For the final version, we envision several parts of the chair to automatically and precisely adjust according to this measurement-based analysis of the user’s current posture. These parts will move the user very slowly, almost unnoticeable, to give a smooth and comfortable user experience. 

The sensors will also allow information sharing to healthcare professionals and partners. Attributes like redesigned armrests and a cozy, homely overall look of the chair will gain the users’ trust to support them living at home unobtrusively. 

 

In further development, details, especially regarding the automation of the chair, will need to be elaborated upon. We are confident that this innovative seating system will support and benefit seniors, especially those affected by dementia, allowing them to live in their own home happily for longer.
