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.

1 - 8 . (canceled) 
     
     
         9 . One or more computer-readable storage media storing computer-executable instructions that when executed perform operations comprising:
 receiving user input at a digitizer overlaying a display;   determining whether the user input moves beyond a first threshold;   responsive to the user input moving beyond the first threshold, classifying the user input as a stroke; and   in response to the stroke, performing an action on an object or area within proximity to a start of the stroke.   
     
     
         10 . The one or more computer-readable storage media of  9  wherein the user input is caused by the digitizer detecting a user's finger in contact with the digitizer. 
     
     
         11 . The one or more computer-readable storage media of  claim 9  wherein the first threshold includes at least one of: a distance of movement, a rate of movement, an acceleration of movement, or any combination thereof. 
     
     
         12 . The one or more computer-readable storage media of  claim 9  wherein performing the action further comprises:
 when the stroke started within proximity to a draggable object and a drag threshold had been exceeded, performing a function with the draggable object based on the stroke; and 
 when the drag threshold has not been exceeded, maintaining the draggable object at a current state. 
 
     
     
         13 . The one or more computer-readable storage media of  claim 9  wherein performing the action further comprises:
 when the stroke did not start within proximity to a draggable object, determining whether an area under the stroke is inkable; and 
 when the area under the stroke inkable, performing inking based on the stroke. 
 
     
     
         14 - 20 . (canceled) 
     
     
         21 . A method comprising:
 receiving user input at a touch-sensitive display;   determining whether the user input moves beyond a first threshold;   responsive to the user input moving beyond the first threshold, classifying the user input as a stroke; and   in response to the stroke, performing an action on an object or area within proximity to a start of the stroke.   
     
     
         22 . The method of  claim 21 , wherein the user input is caused by detecting a user's finger in contact with the touch-sensitive display. 
     
     
         23 . The method of  claim 21 , wherein the touch-sensitive display comprises a digitizer. 
     
     
         24 . The method of  claim 21 , wherein, if the stroke started within proximity of a draggable object and a drag threshold has been exceeded, the action on the object or area comprises a drag of the draggable object. 
     
     
         25 . The method of  claim 24 , wherein the drag of the draggable object relocates the draggable object to a location within proximity of an end location of the user input. 
     
     
         26 . The method of  claim 24 , wherein, if the drag threshold has not been exceeded, the method further includes maintaining the draggable object at a current location. 
     
     
         27 . The method of  claim 21 , further comprising determining whether an area under the stroke is inkable. 
     
     
         28 . The method of  claim 27 , further comprising, upon determining that the area under the stroke is inkable, performing inking based on the stroke. 
     
     
         29 . A method comprising:
 receiving user input at a touch-sensitive display;   determining whether the user input moves beyond a first threshold representing a stroke;   determining whether the user input ends before an amount of time representing a hold or hold and drag; and   responsive to the user input failing to exceed the first threshold and ending before the amount of time, classifying the user input as a tap.   
     
     
         30 . The method of  claim 29 , wherein the user input is caused by the touch-sensitive display detecting a user's finger in contact with the touch-sensitive display, and the user input ends when the touch-sensitive display no longer detects the user's finger in contact with the touch-sensitive display. 
     
     
         31 . The method of  claim 29 , wherein the user input is caused by the touch-sensitive display detecting a user's finger in proximity to the touch-sensitive display, and the user input ends when the touch-sensitive display no longer detects the user's finger in proximity to the touch-sensitive display. 
     
     
         32 . The method of  claim 29 , wherein the touch-sensitive display includes a digitizer. 
     
     
         33 . The method of  claim 32 , wherein the user input comprises contact of a stylus to the touch-sensitive display including the digitizer. 
     
     
         34 . The method of  claim 29 , further comprising, in response to classifying the user input as a tap, placing an insertion point at a location within proximity of the tap when the location of the tap was within text. 
     
     
         35 . The method of  claim 29 , further comprising, in response to classifying the user input as a tap, selecting an object within proximity of the tap when the object has not already been selected.
