A growing aging population and a longer lifespan have contributed to the increase in the number of people living with dementia. The total number of people with dementia worldwide is expected to triple by 2050, meaning 131 million people will be living with the disease.

Dementia is a term used to define a group of symptoms associated with the decline of cognitive abilities like memory, thinking, calculation, etc., that are severe enough to affect a person’s ability to perform everyday activities. Memory loss, the most common symptom of these conditions, causes the affected person to forget things easily and often get lost or lose track of conversation. Research has shown that people with dementia in the early stages long for independence and social interaction. Thus, there is an increased need to support the requirements and concerns of people with dementia to maintain their independence as long as possible.

Developing a multi-sensory wayfinding system could help people with mild cognitive impairments, like early-stage dementia, navigate their neighborhoods independently and help them stay physically and mentally active.
