Hi Sumin, Nice bibliography. I am very interested in the question of how products can be used to help people with dementia to continue functioning as independently as possible. There is quite a bit of work going on right now to develop home monitoring system that can silently watch a person to try to determine if something is wrong and if they need help. For example, a system of cameras might be used to track a person's position in their apartment. If they do something unexpected, like stay in the bathroom for four hours, the system will place a call to a family member of other caretaker, who can then try to find out if there is a problem. While this is an expensive system, the alternative of having a full-time nurse, or placing the person in a nursing home are much more expensive. So, there is a strong economic incentive to make things that really work. Also, almost everybody would prefer to live in their own home, independently, rather than move to some institution or have a stranger live with them.
Another interesting product idea for helping deal with the increasing rates of dementia (due to the aging population) is people getting lost. I have seen signs that people put up on bus stops to alert people that someone they know has gotten lost and may need help. Some work has been done in this area, where people who are risk are "tagged" in some way to make it easier for people to find or help them if they get in trouble. Take a look at this article for more information on tagging, and [this one[(http://www.sarinfo.bc.ca/alzheimerSOP.htm) that discusses what to do when someone does get lost. Steven
