Pointing error avoidance scheme
Technologies are generally described for a pointing error avoidance scheme. In some examples, a method performed under control of a computing system with a display, may include detecting an input event applied to the computing system at a pointing location in a first area of the display, determining a first time duration for which the pointing location has been maintained in the first area, determining a second time duration for which the pointing location had been previously maintained in a previous area of the display before the pointing location moved into the first area, and determining an intended pointing location of the input event based at least in part on at least one of the first time duration and the second time duration.
1. A method performed under control of a computing system with a display, comprising:
detecting an input event applied to the computing system at a pointing location in a first area of the display;
determining a first time duration for which the pointing location has been maintained in the first area;
determining a second time duration for which the pointing location had been previously maintained in a previous area of the display before the pointing location moved into the first area; and
determining an intended pointing location of the input event based at least in part on the first time duration being less than the second time duration proportionally weighted by empirical data analyzed from behavior of a user of the computing system.
2. The method of claim 1 ,
wherein the computing system is configured to receive an input signal from an external pointing input device,
wherein the input event is triggered by clicking of a button of the external pointing input device, and
wherein the pointing location is a location on the display to which the external pointing input device is directed.
3. The method of claim 1 ,
wherein the display includes a touch screen display,
wherein the input event is triggered by at least one of touching and gesturing on the touch screen display, and
wherein the pointing location is a location on the touch screen display at which an object contacts.
4. The method of claim 1 , wherein the second time duration is further offset by additional empirical data analyzed from behavior of a user of the computing system.
5. The method of claim 1 , wherein each of the first area and the previous area is associated with a key of a virtual keyboard displayed on the display.
6. The method of claim 1 ,
wherein the computing system comprises a motion sensing input device,
wherein the input event is triggered by at least one of pointing a finger, making a predetermined gesture and speaking a predetermined command, and
wherein the pointing location is at least one of a location pointed to by the finger, predetermined location indicated by a predetermined gesture and a predetermined location indicated by a predetermined spoken command.
7. A computing system, comprising:
a pointing location tracking unit configured to:
track, in terms of time, a change of a pointing location to which an input device is directed,
determine a first time duration for which the pointing location has been maintained in a first area, and
determine a second time duration for which the pointing location had been previously maintained in a previous area before the pointing location moved into the first area,
wherein the input device is configured to interact with the computing system;
an input event detection unit configured to detect an input event applied from the input device to the computing system; and
an intended pointing location determination unit configured to:
determine an intended pointing location of the input event detected by the input event detection unit, based at least in part on the first time duration being less than the second time duration proportionally weighted by empirical data analyzed from behavior of a user of the computing system.
8. The computing system of claim 7 ,
wherein the input device includes an external pointing input device,
wherein the input event is triggered by clicking of a button of the external pointing input device, and
wherein the pointing location is a location on a display of the computing system to which the external pointing input device is directed.
9. The computing system of claim 7 , wherein the second time duration is further offset by additional empirical data analyzed from behavior of a user of the computing system.
10. The computing system of claim 7 ,
wherein the computing system further comprises a motion sensing input device,
wherein the input event is triggered by at least one of pointing a finger, making a predetermined gesture and speaking a predetermined command, and
wherein the pointing location is at least one of a location pointed to by the finger, predetermined location indicated by a predetermined gesture and a predetermined location indicated by a predetermined spoken command.
11. A non-transitory computer-readable medium having stored thereon computer-executable instructions that, in response to execution, cause a computing system to perform operations, comprising:
tracking, in terms of time, a change of a pointing location to which an input device is directed, the input device interacting with the computing system;
detecting an input event applied from the input device to the computing system; determining a first time duration for which the pointing location has been maintained in a first area;
determining a second time duration for which the pointing location had been previously maintained in a previous area before the pointing location moved into the first area;
determining a ratio of the first time duration to a second time duration; and
determining a user-intended pointing location of the input event based at least in part on the first time duration being less than the second time duration proportionally weighted by empirical data analyzed from behavior of a user of the computing system.
12. The non-transitory computer-readable medium of claim 11 , wherein the operations further comprise:
determining whether the input event is made at a user-intended pointing location based at least in part on the tracked change of the pointing location.
13. The non-transitory computer-readable medium of claim 11 , wherein the second time duration is further offset by additional empirical data analyzed from behavior of a user of the computing system.
14. The non-transitory computer-readable medium of claim 11 ,
wherein the computing system comprises a display,
wherein the computing device is configured to receive an input signal from an external pointing input device,
wherein the input event is triggered by clicking of a button of the external pointing input device, and
wherein the pointing location is a location on the display to which the external pointing input device is directed.
15. The non-transitory computer-readable medium of claim 11 ,
wherein the computing system comprises a touch screen display,
wherein the input event is triggered by at least one of touching and gesturing on the touch screen display, and
wherein the pointing location is a location on the touch screen display at which an object contacts.

wherein the computing system comprises a motion sensing input device,
wherein the input event is triggered by at least one of pointing a finger, making a predetermined gesture and speaking a predetermined command, and
wherein the pointing location is at least one of a location pointed to by the finger, predetermined location indicated by a predetermined gesture and a predetermined location indicated by a predetermined spoken command.
