Student’s stick helps people with dementia to live independently
SMART WALKING DEVICE TRACKS MOVEMENTS FOR ‘BEHAVIOUR MAP’
A student at Loughborough University has created a mobility device to help people with dementia live independently and safely in their home for longer.
Final year industrial design student James Bayliss designed AIDE, which comprises a smart walking stick, a wall charger and a series of Bluetooth beacons, placed around the home.
The product works by tracking a person’s daily movements in their home and identifying any actions that are out of the ordinary.
As the person moves around the house with the walking stick, the stick communicates data to the beacons.
Using pattern recognition software and mach ine learning, this data is turned into a behaviour map.
AIDE can identify unusual behaviour and then alert the care network via an app so someone can make contact with the person with dementia. This could include if a person is in the bathroom for much longer than usual, or if the stick moves in a certain manner, which may suggest a fall.
“This system allows the care network to be able to intervene if something goes wrong without having to be present the whole time. It’s about creating a safety net”, said James.
“In my early research, it became very clear from speaking to members of care networks for people with dementia that a cohesive approach to care is what allows people with dementia to feel comfortable in their own space and allow them to continue to align with their sense of self and, as an extension of this, their own independence.
“Currently, the undertaking required to orchestrate and organise all of the independent actors that make up a care network is massively stressful for the primary carers and can feel very disjointed for the person with dementia.
“AIDE aims to streamline this.” Several aspects of the electronic and mechanical functions have been prototyped and tested by James, including an adjustable code for fall detection and a chip that allows the system to understand the orientation and movement of the walking stick.
He now hopes to bring all the technology together into a fully functioning prototype and perfect the behavioural mapping and app.
He said: “This project is a product of a large amount of research and design development that has allowed me to understand and explore the problems and pain points that are experienced by people trying to retain independence within their own home while dealing with the progression of dementia.
“I would hope that this rigorous process has yielded a product proposal that could genuinely make a difference for both those who have dementia and the care network they have around them.”
According to Alzheimer’s Research UK, one million people in the UK will have dementia by 2025 and this will increase to two million by 2050.
This allows the care network to be able to intervene if something goes wrong without being present the whole time
