Is there a way to provide another method of interaction with your mobile device that expands the capabilities of touch? Another sensor that can be used for alternative methods of interaction is a magnetometer. The magnetometer senses changes in the magnetic field in all three axes (x,y,z). If the magnetic field can be detected, would there be a way to alter the magnetic field? This can be accomplished by using an external magnet. The external magnet will alter the magnetic field thus producing different (x,y,z) values.   This new user interaction requires the use of a magnet attached or placed on a finger or embedded in a ring. The use of a magnet and a magnet sensor will increase the area of user interaction around and above the phone. Gestures and taps in 2D and 3D space can be recognized and attached to certain actions. One would also be able to interact with a mobile device without physical contact with that device. For example, interacting with our your  phone while its in your pocket or purse. These are just a few use possibilities of interacting with your phone by using a magnet. Using the magnet based interactions described above, we will be building a photo browser + drawing application that will allow you to flip through, select, and annotation/draw on photos using magnets and touch. Magnets will be embedded on to physical objects (e.g. styluses) to represent paintbrushes. This will allow the user to have a more natural interaction with the app.
