Subject: Waiting for Godot, er, Bluetooth
I am writing in response to the article "Waiting for Godot, er, Bluetooth," Dec. 13, 2001.
The article says: "For example, a man in a wheelchair puts on a pair of goggles embedded with Bluetooth chips and opens a supermarket door by glancing at it."
But here's an alternative....
You put a motion sensor above the door. It detects someone approaching the door and opens it. No need for the expensive goggles, the Bluetooth radio infrastructure and all the associated software.
A lot of supermarkets in the U.K. have had this motion sensor technology for a while now, and it works pretty well.
