Triggered by a hand against the glass of a door or window

Modern engineering can be subdivided into the disciplines of mechanical, electrical/electronic, software and socially-beneficial. This project is in the latter category. When Chris, the author’s girlfriend, opened a retail art gallery, compliance with the Disability Discrimination Act (1995) was a problem. Mobility-impaired people would have trouble with the steps and right-angle turn into the shop and, being a Grade Two listed building, structural alteration was not possible.

This project permits a disabled person to attract attention through a glass window.
