Research into design for the ageing population
Currently I am developing a product aimed at increasing the safety of the elderly when mobile in reduced lighting. This is a retrofittable attachment for aids such as walking sticks, zimmer frames and wheelchairs. It improves the definition of the ground in front of the user by projecting a laser grid.
As the light surrounding the attachment decreases the brightness of the LEDs increases. This will reduce the chances of trips and falls. Fractures following falls in the elderly are a major cause of pain, disability and even death. Falls cost the NHS over £350 million every year. Arduino (open source programming platform) has been used to control the sensors and lights. The idea came from a conversation with an elderly couple during my research.
