Feedback via an input device and scribble recognition

A system for recognizing scribble input intended to test pen attributes, the system comprising:

• a memory storage;
• and
• a processing unit coupled to the memory storage, wherein the processing unit is operative to:
• receive first input via an input device, wherein the first input is received at a location corresponding to a margin of an electronic document;
• based on the location of the received first input on an input surface being in the margin of the electronic document and a length of time associated with drawing the received input, determine if the received first input is scribble input intended to test pen attributes;
• determine whether to erase the scribble input by:
• receiving a second input via the input device;
• determining that the second input is not in the margin of the electronic document;
• evaluating a size of the second input relative to the scribble input;
• and
• determining, based on the second input not being in the margin and the size of the second input, that the second input is not a continuation of the scribble input;
• and
• erase, when the second input is determined not to be a continuation of the scribble input, the scribble input upon receiving the second input away from the scribble input.

A method for testing input device attributes, the method comprising:

• receiving first input on an input surface via an input device;
• determining if the received first input is associated with a scribble input for determining attributes of the input device based on a location corresponding to a margin of an electronic document of the received first input on the input surface;
• in response to determining that the received first input is associated with the scribble input, making a determination whether to erase the scribble input, wherein making the determination to erase the scribble input comprises:
• receiving a second input via the input device;
• evaluating a location of the second input to the scribble input;
• determining that the location of the second input to the scribble input is not in the margin of the electronic document;
• and
• determining, based on the location of the second input, that the second input is not a continuation of the scribble input;
• and
• based on the received first input being associated with the scribble input, erasing the scribble input, but not the second input, after a predetermined amount of time after receiving the scribble input.
