The theory of Around Device Interaction (ADI) has recently gained a lot of attention in the field of Human-Computer Interaction (HCI). As an alternative to the classic data entry methods, such as keypads and touch screens, ADI founds a 3D user interface that extends to the peripheral area of a device. In this project we introduce a revolutionary interaction framework that is based on the idea of ADI. The proposed method constitutes a touchless data entry system that is based on the interaction between the magnetic fields around a device and a properly shaped magnet. The magnetic field that surrounds the device is generated by a magnetic sensor (compass) that is embedded in the new generation of mobile phones such as Apple iPhone 3Gs and 4G, and Google Nexus one. The user movements of the properly shaped magnet in front of the device, then, deforms the sensor's original magnetic field pattern whereby we can constitute a new means of communication between the user and the device. Thus, the magnetic field encompassing the device plays the role of a communication channel and encodes the hand-movement patterns of the user into temporal changes of the sensor's magnetic field. In the back-end of the communication, an engine such as a mobile phone or a Personal Digital Assistant (PDA) samples the momentary status of the field during a trial and recognizes the user's pattern by matching it against some pre-recorded templates.
