1. A method for recognizing a gesture of a gesture object in a plurality of recorded data objects, the recorded data objects being recorded over time, the method comprising:

  • determining at least one set of gesture angles using the plurality of recorded data objects, wherein each of the gesture angles in the at least one set of gesture angles comprises an angle measurement between two positions of the gesture object, the two positions recorded in successive data objects of the plurality of recorded data objects, wherein the at least one set of gesture angles further comprises a first subset of gesture angles and a second subset of gesture angles;

    determining a first histogram representing a frequency of angles based on the first subset of gesture angles and a second histogram representing a frequency of angles based on the second subset of gesture angles;

    recognizing the gesture based on a comparison of the first histogram and the second histogram to a respective first model histogram and second model histogram, each model histogram representing a frequency of angles of a subdivision of gestures of a gesture model; and

    modifying a behavior of the device in response to the recognizing the gesture.
