Haptic effects with proximity sensing
A method of generating haptic effects on a device includes detecting the presence of an object near an input area of the device and generating a haptic effect on the device in response to the presence detection.
1. A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to generate haptic effects on a device, the generating comprising:
detecting a position of an object relative to a touchscreen of the device, wherein the detecting occurs while the object is hovering over the touchscreen, and the device comprises a plurality of selectable functionality displayed on the touchscreen;
based on the detected position, including the proximity of the hovering to one functionality of the plurality of selectable functionality, determining a functionality of the device; and
generating a first haptic effect on the device while the object is hovering based at least on the determined functionality.
2. The computer readable medium of claim 1 , further comprising:
generating a user interface on the touchscreen that displays a plurality of user interface elements providing the selectable functionality for the device.
3. The computer readable medium of claim 2 , wherein the user interface elements comprise at least one of a virtual button, a virtual jog dial or a series of menus.
4. The computer readable medium of claim 1 , wherein the first haptic effect is a vibrotactile haptic effect and is generated on a housing of the device.
5. The computer readable medium of claim 1 , further comprising:
detecting an operating condition of the device;
generating a second haptic effect based at least on the detected operating condition.
6. The computer readable medium of claim 5 , wherein the detected operating condition comprises a proximity to a user of the device.
7. The computer readable medium of claim 6 , wherein the detected operating condition comprises the device is near a face of the user and wherein the second haptic effect comprises a reduced magnitude haptic effect.
8. The computer readable medium of claim 1 , wherein the detected position is based on a signal from one or more proximity sensors.
9. The computer readable medium of claim 1 , wherein the first haptic effect is generated without the object contacting the touchscreen.
10. A method of generating haptic effects on a device, the method comprising:
detecting a position of an object relative to a touchscreen of the device, wherein the detecting occurs while the object is not contacting the touchscreen, and the device comprises a plurality of selectable functionality displayed on the touchscreen;
based on the detected position, including the proximity of the object to one functionality of the plurality of selectable functionality, determining a functionality of the device; and
generating a first haptic effect on the device while the object is not contacting the touchscreen based at least on the determined functionality.
11. The method of claim 10 , further comprising:
generating a user interface on the touchscreen that displays a plurality of user interface elements providing the selectable functionality for the device.
12. The method of claim 11 , wherein the user interface elements comprise at least one of a virtual button, a virtual jog dial or a series of menus.
13. The method of claim 10 , wherein the first haptic effect is a vibrotactile haptic effect and is generated on a housing of the device.
14. The method of claim 10 , further comprising:
detecting an operating condition of the device;
generating a second haptic effect based at least on the detected operating condition.
15. The method of claim 14 , wherein the detected operating condition comprises a proximity to a user of the device.
16. The method of claim 15 , wherein the detected operating condition comprises the device is near a face of the user and wherein the second haptic effect comprises a reduced magnitude haptic effect.
17. The method of claim 10 , wherein the detected position is based on a signal from one or more proximity sensors.
18. A haptically enabled device comprising:
a proximity sensor;
a processor coupled to the proximity sensor;
a haptic feedback system coupled to the processor; and
a touchscreen coupled to the processor and adapted to display a plurality of selectable functionality;
wherein the processor is adapted to:
detect a position of an object relative to the touchscreen based on a signal received from the proximity sensor, wherein the detecting occurs while the object is hovering over the touchscreen;
based on the detected position, including the proximity of the hovering to one functionality of the plurality of selectable functionality, determine a functionality of the device; and
generate a first haptic effect on the device while the object is hovering based at least on the determined functionality.
19. The device of claim 18 , the processor further adapted to:
generate a user interface on the touchscreen that displays a plurality of user interface elements providing the selectable functionality for the device.
20. The device of claim 19 , wherein the user interface elements comprise at least one of a virtual button, a virtual jog dial or a series of menus.
21. The device of claim 18 , further comprising an actuator and coupled to the processor and a housing, wherein the first haptic effect is a vibrotactile haptic effect and is generated by the actuator on the housing.
22. The device of claim 18 , the processor further adapted to:
detect an operating condition of the device;
generate a second haptic effect based at least on the detected operating condition.
23. The device of claim 22 , wherein the detected operating condition comprises a proximity to a user of the device.
24. The device of claim 23 , wherein the detected operating condition comprises the device is near a face of the user and wherein the second haptic effect comprises a reduced magnitude haptic effect.
