Feedback via an input device and scribble recognition
Feedback via an input device associated with an interaction with a point of interest (POI) and scribble recognition is provided. When using an input device to navigate a GUI, various POIs may be determined as elements beneficial for a user to notice, pay attention to, or avoid. When an input is received that may be associated with a POI, feedback may be provided. Feedback may include haptic, visual, or audible feedback. Scribble recognition may also be provided. When using an input device (e.g., digital pen), a user may “scribble” in a margin to test pen attributes. Upon recognizing a scribble, alternative pen attributes may be presented in a contextual menu. In addition, the scribble may be automatically erased upon selection of a pen attribute or upon receiving input in another area of the UI or alternatively, feedback may be provided prior to erasure of the scribble input.
1. A method for providing feedback via an input device, the method comprising:
receiving a first input on an input surface 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 the input surface being in the margin of the electronic document and a length of time associated with drawing the received first input, determining if the received first input is associated with a scribble input intended to test pen attributes;
in response to determining that the received first input is associated with the scribble input intended to test pen attributes, 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;
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
in response to making the determination to erase the scribble input, providing feedback via the input device that the scribble input is about to be erased.
2. The method of claim 1 , wherein providing feedback via the input device comprises providing one or more of:
a haptic feedback;
a visual feedback; or
an audible feedback.
3. The method of claim 2 , wherein providing the haptic feedback includes providing a vibration.
4. The method of claim 2 , wherein providing the haptic feedback includes providing a change in a friction level between an input portion of the input device and the input surface for receiving the input via the input device.
5. The method of claim 2 , wherein providing the haptic feedback includes providing a movement of the input device via an internal gyroscope.
6. The method of claim 1 , wherein if the received first input is associated with the scribble input, further comprising erasing the scribble input after a predetermined amount of time after receiving the scribble input.
7. The method of claim 1 , wherein no portion of the second input overlaps the received first input.
8. The method of claim 1 , wherein the determination that the received first input is scribble input is further based on the received first input not being recognized as an alphanumeric character, a symbol, or a shape.
9. 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.
10. The system of claim 9 , wherein the processing unit is further operative to, upon determining the received first input is scribble input intended to test pen attributes, provide one or more selectable alternative pen attributes for further input.
11. The system of claim 10 , wherein the processing unit is further operative to receive a selection of an alternative pen attribute and apply the selected alternative pen attribute to the input device.
12. The system of claim 9 , wherein the processing unit is further operative to determine if the received first input is scribble input based on one or more of:
a configuration of the input; or
a length of time associated with receiving additional input after receiving the input.
13. 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.
14. The method of claim 13 , wherein making the determination to erase the scribble input further comprises receiving an indication of receiving the second input via the input device away from the scribble input.
15. The method of claim 13 , wherein making the determination to erase the scribble input further comprises detecting a passing of a predetermined amount of time after receiving the scribble input without receiving additional input.
16. The method of claim 15 , further comprising receiving an indication to cancel erasing the scribble input and cancelling erasing the scribble input.
17. The method of claim 16 , wherein receiving the indication to cancel erasing the scribble input includes receiving the second input on the input surface via the input device.
18. The method of claim 13 , wherein providing feedback via the input device comprises providing one or more of:
a haptic feedback;
a visual feedback; or
an audible feedback.
19. The method of claim 13 , wherein receiving each input on the input surface via an input device comprises receiving each input via a digital pen device.
20. The method of claim 13 , wherein the location of the received second input is in the body of the electronic document.
