SYSTEM AND METHOD FOR MANIPULATING AN OBJECT IN A THREE-DIMENSIONAL DESKTOP ENVIRONMENT

An electronic device, method and interface for the device, for performing an action with a processor through a three-dimensional desktop environment is disclosed. A three-dimensional desktop environment is generated by a display and projected into a real space. At least one ultrasonic transducer propagates an ultrasonic pulse into the real space and receives a reflection of the ultrasonic pulse from a user object in the real space. A user action of the user object within the three-dimensional desktop environment is determined using the reflection of the ultrasonic pulse. The processor performs the action based on the determined user action.
