I will look into technology designed to help seniors with hearing, sight and mobility impairments. I have very little knowledge in this field. After browsing the Internet for quite sometime, I found  an online Canadian company with a range of products . If  you look at the section showing the most popular products, you may find something of interest to you.

Go to https://www.specialneedscomputers.ca, they have a very large inventory.

On all topics covering special needs I would appreciate your advice. In other words if you have information that could be useful to some of my readers simply send me your observations and comments along with any corroborating links to websites covering the topic. I will post only information that I have verified and authenticated.
