Abstract
Methods and systems for receiving an erasure gesture input and accordingly deleting content in a viewable area of a multi-touch input display device are disclosed. A touch gesture can be detected on a touch screen. One or more direction changes associated with the touch gesture can be detected and the angle of each of the direction changes can be determined to meet a predetermined threshold. The touch gesture can be detected as no longer touching the touch screen and a polygon can be generated based on each of the direction changes associated with the touch gesture.
Claims24
A computer implemented method, comprising:
- detecting, by a processor, a touch gesture on a touch screen;
- detecting that a pressure of the touch gesture exceeds a predetermined threshold pressure value;
- identifying one or more direction changes of the touch gesture;
- determining that an angle of each of the one or more direction changes of the touch gesture exceeds a predetermined angle threshold value wherein the predetermined angle threshold value depends on the pressure of the touch gesture;
- detecting that the touch gesture has terminated;
- identifying content on the touch screen associated with the touch gesture in response to determining that the angle of each one of the one or more direction changes exceeds the predetermined angle threshold value;
- and
- removing the content associated with the touch gesture.
A system, comprising:
- one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, cause the one or more computers to perform operations comprising:
- detecting a touch gesture on a touch screen;
- detecting that a pressure of the touch gesture exceeds a predetermined threshold pressure value;
- identifying one or more direction changes of the touch gesture;
- determining that an angle of each of the one or more direction changes of the touch gesture exceeds a predetermined angle threshold value wherein the predetermined angle threshold value depends on the pressure of the touch gesture;
- detecting that the touch gesture has terminated;
- identifying content on the touch screen associated with the touch gesture in response to determining that the angle of each of the one or more direction changes meets the predetermined angle threshold value;
- and
- removing the content associated with the touch gesture.
A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:
- detecting a touch gesture on a touch screen;
- detecting that a pressure of the touch gesture exceeds a predetermined threshold pressure value;
- identifying one or more direction changes of the touch gesture;
- determining that an angle of each of the one or more direction changes of the touch gesture exceeds a predetermined angle threshold value wherein the predetermined angle threshold value depends on the pressure of the touch gesture;
- detecting that the touch gesture has terminated;
- identifying content on the touch screen associated with the touch gesture in response to determining that the angle of each of the one or more direction changes exceeds the predetermined angle threshold value;
- and
- removing the content associated with the touch gesture.
