1. A computing apparatus coupled to a digitizer, the digitizer receiving user input, comprising a processor coupled to the digitizer, the processor being configured to:
- classify the user input as a stroke if the user input satisfies a first move threshold;
classify the user input as a tap if the user input fails to satisfy both the first move threshold and a time threshold;
classify the user input as a hold if the user input satisfies the time threshold but fails to satisfy both the first move threshold and a second move threshold different from the first move threshold;
classify the user input as a hold and drag if the user input satisfies both the time threshold and the second move threshold but fails to satisfy the first move threshold;
responsive to the user input being classified as a stroke, determining whether an object associated with the stroke is draggable;
responsive to the object being draggable, determining whether the user input satisfies a drag threshold; and
responsive to the object not being draggable, determining whether the object is inkable.

Abstract
The present invention relates to a system, method and medium for receiving and acting upon user input. In one embodiment, the user may only have access to a limited input device, like a stylus. Using the present invention, a user is provided with intuitive responses from the system based on inputs from the limited input device.

5. A computer-readable medium storing computer-executable instructions for performing steps comprising:
-
receiving user input to a digitizer; first determining whether the user input moves at least a first distance; second determining whether the user input ends before a certain amount of time; and responsive to the user input failing to move at least the first distance within the certain amount of time and failing to end before the certain amount of time third determining whether the user input moves at least a second distance larger than the first distance, wherein the computer-executable instructions are further for performing a step of responsive to the user input moving at least the first distance as determined by the step of first determining, fourth determining whether the input begins on a draggable object, and wherein the computer-executable instructions are further for performing a step of, responsive to the user input not beginning on a draggable object as determined by the step of fourth determining, fifth determining whether the user input is in an inkable location.
