Touch interaction with mobile phones enable users to have a more natural interaction with the device, since touch is a natural way of direct accessing an ob ject of interest. But one disadvantage is occlusion; i.e., the user loses a high percentage of information presented on the small screen of the mobile phone during the interaction using his big finger . On the other hand, interaction enhanced with accelerometers can react according to the device movements, e.g., while the user is tilting the mobile phone, the UI will be rotated. A drawback is that the user needs to move the whole device while interacting and consequently loses his eye contact on the phone s screen (screen-absence problem). Finteraction (Finger Interaction) is a new interaction concept that solves the occlusion and screen-absence problems. User interact with a large public display using his mobile phone. Moving the index finger in front of the camera at the backside of the mobile phone, the user can interact with the large public display even on the move.
