“Touch Wood” is a touch sensitive pad, with three different panels, each panel triggering a different sound to be played. The primary function of the product is to 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. The limitless amount of knocking patterns, and different sounds available, means that the each user can have a completely original doorbell, and never grow tired of hearing it. 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. With the ever growing popularity of social networking, “Touch Wood” could also be incorporated by using the “check in” feature on Facebook, or to Tweet your location. Each user could have their own pattern of knocks to act as a password and then allow their friends to know where they are.
