From the Nokia site:

- Neuscreen (APAC) - This application utilizes the drawing, touch-screen and camera functionalities of a Nokia N95 device connected to a normal television set to track the motion of a simple pen light and enable "virtual" drawing, as well as projection and manipulation directly on the TV screen of images stored on the mobile device.

Never knew my N95 had touch screen!!! Mine must be a faulty one then.
