Device processing method and electronic device

An electronic device, comprising:

• a processor;
• a memory device that stores instructions executable by the processor to:
• receive user input comprising a predetermined gesture;
• determine a first set of coordinates associated with the predetermined gesture;
• receive, after the user input, another user input comprising the predefined gesture;
• determine a second set of coordinates associated with the predetermined gesture of the another user input, wherein the second set of coordinates is different than the first set of coordinates;
• compare the first and second set of coordinates;
• and
• determine, based on the comparing, an offset between the first and second set of coordinates.

A product, comprising:

• a storage device that stores code, the code being executable by a processor and comprising:
• code that receives user input comprising a predetermined gesture;
• code that determines a first set of coordinates associated with the predetermined gesture;
• code that receives, after the user input, another user input comprising the predetermined gesture;
• code that determines a second set of coordinates associated with the predetermined gesture of the another user input, wherein the second set of coordinates is different than the first set of coordinates;
• code that compares the first and second sets of coordinates;
• and
• code that determines, based on the comparing, an offset between the first and second set of coordinates.
