The invention described in this article essentially involves combining a stationary bicycle with Google Street View, for the benefit of patients with Alzheimer's disease. As I read the article, I realized that the benefit of such a combination could go way beyond Alzheimer's disease. I could imagine this being of benefit to many people with Parkinson's disease, and even disease-free elderly people in general.

More recently, I came across a research paper that seems to lend support to the idea that this invention could be of use in the treatment of Parkinson's disease [1].
