First Claim
Patent Images
1. A method of generating haptic effects on a device, said method comprising:
- detecting the presence of an object near an input area of the device and not in contact with the device;
calculating an approximate contact time when the object will contact the input area;
andinitiating a haptic effect on the device in response to the presence detection;
wherein the initiating comprises energizing an actuator that has a delay time to reach a peak haptic output, and wherein the energizing occurs at a time in advance of the approximate contact time so that the delay time has elapsed by the approximate contact time;
wherein the haptic effect is generated on the device by the approximate contact time when the object contacts the input area.

9. A haptically enabled device comprising:
-
an input area; a proximity sensor coupled to said input area; and a haptic feedback system coupled to said input area; wherein said proximity sensor is adapted to detect the presence of an object near the input area but not touching the input area, and the haptic feedback system is adapted to calculate an approximate contact time when the object will contact the input area and initiate a haptic effect before the object touches the input area; wherein the initiating comprises energizing an actuator that has a delay time to reach a peak haptic output, and wherein the energizing occurs at a time in advance of the approximate contact time so that the delay time has elapsed by the approximate contact time; wherein the haptic effect is output on the device by the approximate contact time when the object contacts the input area. - View Dependent Claims (10, 11, 12)

13. A computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to generate haptic effects on a device, said processor:
-
detecting the presence of an object near an input area of the device and not touching the input area; determining an approximate contact time when the object will contact the input area; and initiating a haptic effect on the device in response to the presence detection; wherein the initiating comprises energizing an actuator that has a delay time to reach a peak haptic output, and wherein the energizing occurs at a time in advance of the approximate contact time so that the delay time has elapsed by the approximate contact time; wherein the haptic effect is generated on the device by the approximate contact time when the object contacts the input area. - View Dependent Claims (14, 15, 16, 17, 18, 19)
