After much alteration in the direction of the project, a final concept and design had been decided upon. The product will be a touch sensitive pad, with three different panels, each panel triggering a different sound to be played. The primary function of the product will be a “doorbell”. The pad will be placed on the wall next to, or on the users front door. When a visitor approaches the door, instead of ringing a bell, or knocking on the door, they will knock on the pad, and each different area knocked upon will play a different sound throughout the house to alert the home owner. People who live in the house will soon be able to recognise who is at the door without actually seeing them, all because each individual will have their own personal knock.
