Claim Text:
1. An electronic device for determining a first positional information and a second positional information regarding a user input object, such as at least one user hand or at least one stylus, the electronic device comprising: a touch-sensitive surface; contact-free detection unit; and a controller that is operatively connected with the touch-sensitive surface and with the contact-free detection unit; a gesture recognition module that is a separate module or an integral part of the controller, wherein the first positional information depends on where the user input object contacts the touch-sensitive surface, and wherein the second positional information depends on the spatial configuration of the user input object above the touch-sensitive surface, wherein the controller is adapted for simultaneously and/or alternately determining the first positional information via the touch-sensitive surface and the second positional information via the contact free detection unit, wherein the controller is further configured to determine a gesture performed by the user input object while the input object touches the touch sensitive surface; wherein the gesture recognition module is adapted for identifying the gesture as belonging to a predefined gesture category from tracking at least the second positional information, wherein the gesture belongs to the predefined category if the first position is determined by at least one finger of a hand, and remaining parts of the hand perform the gesture while the first position remains substantially constant; and wherein the electronic device is adapted for transitioning from a first state into a second state when or after the gesture is identified as belonging to the predefined gesture category by the gesture recognition module.
