1. A method for invoking an operation of a communication terminal in response to registering and interpreting a predetermined motion or pattern of an object, the method comprising:
- receiving an indication of a predetermined motion or pattern of a single occurrence of a hand input gesture received from a digital camera of the communication terminal;
identifying at least a first and second centroid in the object;
identifying at least one convex hull in the object;
matching the hand input gesture received from the digital camera with a reference gesture object selected from a set of reference gesture objects based on a positional relationship of the at least first and second centroids in the object and a change in size of the convex hull; and
executing a command related to an item of a display of the communication terminal in response to and upon matching the single occurrence of the hand input gesture received from the digital camera with the reference gesture object.

19. An apparatus comprising:
-
a processor; and a memory including computer program code, wherein the memory and the computer program code are configured to, along with the processor, cause the apparatus at least to perform; invoking an operation of the apparatus in response to registering and interpreting a predetermined motion or pattern of an object; receiving an indication of a predetermined motion or pattern of a single occurrence of a hand input gesture received from an imaging unit; identifying at least a first and second centroid in the object; identifying at least one convex hull in the object; matching the hand input gesture received from the imaging unit with a reference gesture object selected from a set of reference gesture objects based on a positional relationship of the at least first and second centroids in the object and a change in size of the convex hull; and executing a command in the apparatus in response to and upon matching the single occurrence of the hand input gesture received from the imaging unit with the reference gesture object. - View Dependent Claims (20, 21, 22, 23)
