Active feedback interface for touch screen display
An active feedback interface for a touch screen display that includes display of visual cues to indicate when and where the display was touched by a user. The visual cues may change over a period of time in accordance with a particular active or inactive area of the touch screen contacted by a user finger.
1. A method of providing active feedback to a user of an interface for a touch screen display, comprising:
detecting a touch to at least one of an active area and an inactive area of a touch screen display;
starting a timer upon detection of the touch;
displaying a first visual cue of the touch screen display upon detection of the touch;
terminating the first visual cue upon expiration of a period controlled by the timer; and
executing a function activated, by a symbol displayed on the touch screen prior to the detection of the touch, upon release of the touch on the symbol and prior to expiration of period controlled by the timer,
wherein displaying includes displaying the first visual cue at a first location on the touch screen, and subsequently displaying the first visual cue at a second location without releasing the touch;
detecting a release of the touch from the second location without activating a function controlled by the second location, and
after releasing the touch from the second location, touching and releasing the touch from the second location thereby activating the function controlled by the second location.
2. The method of claim 1 , further comprising displaying a second visual cue on the touch screen display when the detected touch is in an active area of the touch screen display.
3. The method of claim 2 , further comprising terminating the second visual cue upon expiration of period controlled by the timer.
4. The method of claim 1 , wherein terminating includes terminating a period started by the timer upon detection of the touch.
5. The method of claim 1 , wherein terminating further includes terminating the first visual cue upon expiration of period controlled by the timer and before the touch is removed from the touchscreen.
6. A non-transitory computer readable medium including program segments for, when executed on a computer device, causing the computer device to:
detect a touch to at least one of an active area and an inactive area of a touch screen display;
start a timer upon detection of the touch;
display a first visual cue of the touch screen display upon detection of the touch;
terminate the first visual cue upon expiration of a period controlled by the timer; and
execute a function activated, by a symbol displayed on the touch screen prior to the detection of the touch, upon release of the touch on the symbol and prior to expiration of period controlled by the timer, wherein
causing the computer device to display further includes display of the first visual cue at a first location on the touch screen, and subsequent display of the first visual cue at a second location without releasing the touch, and wherein when executed on a computer device, the program segments further cause the computer device to:
detect a release of the touch from the second location without activating a function controlled by the second location, and
after detecting the release of the touch from the second location, detecting touching and releasing of the touch from the second location thereby activating the function controlled by the second location.
7. The non-transitory computer readable medium of claim 6 , further comprising program segments for, when executed on a computer device, causing the computer device to display a second visual cue on the touch screen display when the detected touch is in an active area of the touch screen display.
8. The non-transitory computer readable medium of claim 7 , further comprising program segments for, when executed on a computer device, causing the computer device to terminate the second visual cue upon expiration of period controlled by the timer.
9. The non-transitory computer readable medium of claim 6 , wherein the program segment that causes the computer device to terminate the first visual cue further causes the computer to terminate a period started by the timer upon detection of the touch.
10. The non-transitory computer readable medium of claim 6 , wherein the program segment that causes the computer device to terminate the first visual cue upon expiration of period controlled by the timer and before the touch is removed from the touchscreen.
11. A computing system for active feedback in a touch screen display, comprising:
a touch screen display;
a display driver;
a touch detector;
a timer;
a processor;
a data storage device including instructions that, when executed by the processor, cause the touch screen display to detect a touch to at least one of an active area and an inactive area of a touch screen display; start the timer upon detection of the touch; display a first visual cue on the touch screen display upon detection of the touch; terminate the first visual cue upon expiration of a period controlled by the timer; and execute a function activated, by a symbol displayed on the touch screen prior to the detection of the touch, upon release of the touch on the symbol and prior to expiration of period controlled by the timer, wherein
causing the display further includes causing the display of the first visual cue at a first location on the touch screen, and subsequent display of the first visual cue at a second location without releasing the touch, and wherein the data storage device further includes instructions that, when executed by the processor, cause the touch screen display to:
detect a release of the touch from the second location without activating a function controlled by the second location, and
after detecting the release of the touch from the second location, detecting touching and releasing of the touch from the second location thereby activating the function controlled by the second location.
12. The computing system of claim 11 , wherein the data storage device further includes instructions that, when executed by the processor, cause the touch screen display to display a second visual cue on the touch screen display when the detected touch is in an active area of the touch screen display.
13. The computing system of claim 12 , wherein the data storage device further includes instructions that, when executed by the processor, cause the touch screen display to terminate the second visual cue upon expiration of period controlled by the timer.
14. The computing system of claim 11 , wherein the data storage device further includes instructions that, when executed by the processor, cause the touch screen display to terminate a period started by the timer upon detection of the touch.
15. The computing system of claim 11 , wherein the program segment that causes the computer device to terminate the first visual cue further causes the computer to terminate the first visual cue upon expiration of period controlled by the timer and before the touch is removed from the touchscreen.
