memory glasses
n. Eyeglasses that include a small video camera attached to a wearable computer that has been programmed to recognize certain faces and objects and then tell the memory-impaired user who or what they are seeing.
Newfangled "memory glasses" will help anyone suffering from memory loss caused by Alzheimer's disease, stroke and other neurological damage to identify once-familiar family, old friends and neighbourhoods.

Some of these projects are just beginning, while several are in progress, and creation of a few prototype devices is expected soon. Among the tools in development:

"Memory glasses" that a person with early dementia or memory problems might wear which automatically detect certain patterns (loved ones, street signs, grocery items, for example) and then offers audio instructions such as "The person you're looking at is your brother Bill"; "You have bought milk and eggs, but you forgot the bread"; "This is Oak Street; turn left if you want to go home." One goal: Allowing such patients to live independently longer.
