Abstract

Detecting a touch includes receiving image data of a touching object of a user selecting selectable objects of a target surface, determining a rate of movement of the touching object, in response to determining that the rate of movement satisfies a predetermined threshold, modifying a touch detection parameter for detecting a touch event between the touching object and the target surface, and detecting one or more additional touch events using the modified touch detection parameter.

First claim

1 . A non-transitory computer readable medium comprising computer readable code executable by one or more Processors to:
cause a device to capture sensor data of a first portion of a body of a user and a second portion of the body of the user; determine, based on the sensor data, a velocity of one of the first portion of the body of the user and the second portion of the body of the user; and detect one or more touch events between the first portion of the body of the user and the second portion of the body of the user using a touch event parameter selected based on the velocity, wherein the one or more touch events occur apart from the device.

2 . The non-transitory computer readable medium of claim 1 , wherein the first portion of the body of the user comprises a first finger, and wherein the second portion of the body of the user comprises a second finger.

3 . The non-transitory computer readable medium of claim 1 , wherein the computer readable code to determine the velocity comprises computer readable code to determine a velocity of the first portion of the body of the user in relation to the second portion of the body of the user.

4 . The non-transitory computer readable medium of claim 1 , wherein the touch event parameter comprises a threshold hover distance between the first portion of the body and the second portion of the body, and
wherein the computer readable code to modify the touch event parameter comprises computer readable code to modify the threshold hover distance in accordance with the velocity of the one of the first portion of the body of the user and the second portion of the body of the user.

5 . The non-transitory computer readable medium of claim 1 , wherein the computer readable code to modify the touch event parameter comprises computer readable code to modify a touch probability threshold value for determining that a touch event has occurred.

6 . The non-transitory computer readable medium of claim 1 , wherein the computer readable code to detect one or more touch events comprises computer readable code to:
detect a touch event in one or more additional frames of sensor data based on the modified touch event parameter; and determine that a first frame of the one or more frames of sensor data at which the touch is determined to occur is associated with a make touch event.

7 . The non-transitory computer readable medium of claim 6 , further comprising computer readable code to:
determine that a last frame of the one or more frames of the additional sensor data is associated with a break touch event.

8 . A method comprising:
capturing, by a device, sensor data of a first portion of a body of a user and a second portion of the body of the user; determining, based on the sensor data, a velocity of one of the first portion of the body of the user and the second portion of the body of the user; and detecting one or more touch events between the first portion of the body of the user and the second portion of the body of the user using a touch event parameter selected based on the velocity, wherein the one or more touch events occur apart from the device.

9 . The method of claim 8 , wherein the first portion of the body of the user comprises a first finger, and wherein the second portion of the body of the user comprises a second finger.

10 . The method of claim 8 , wherein determining the velocity comprises determining a velocity of the first portion of the body of the user in relation to the second portion of the body of the user.

11 . The method of claim 8 , wherein the touch event parameter comprises a threshold hover distance between the first portion of the body and the second portion of the body, and
wherein modifying the touch event parameter comprises modifying the threshold hover distance in accordance with the velocity of the one of the first portion of the body of the user and the second portion of the body of the user.

12 . The method of claim 8 , wherein modifying the touch event parameter comprises modifying a touch probability threshold value for determining that a touch event has occurred.

13 . The method of claim 8 , wherein detecting one or more touch events comprises:
detecting a touch event in one or more additional frames of sensor data based on the modified touch event parameter; and determining that a first frame of the one or more frames of sensor data at which the touch is determined to occur is associated with a make touch event.

14 . The method of claim 13 , further comprising:
determining that a last frame of the one or more frames of the additional sensor data is associated with a break touch event.

15 . A system comprising:
one or more Processors; and one or more computer readable media comprising computer readable code executable by one or more Processors to: cause a device to capture sensor data of a first portion of a body of a user and a second portion of the body of the user; determine, based on the sensor data, a velocity of one of the first portion of the body of the user and the second portion of the body of the user; and detect one or more touch events between the first portion of the body of the user and the second portion of the body of the user using a touch event parameter selected based on the velocity, wherein the one or more touch events occur apart from the device.

16 . The system of claim 15 , wherein the first portion of the body of the user comprises a first finger, and wherein the second portion of the body of the user comprises a second finger.

17 . The system of claim 15 , wherein the computer readable code to determine the velocity comprises computer readable code to determine a velocity of the first portion of the body of the user in relation to the second portion of the body of the user.

18 . The system of claim 15 , wherein the touch event parameter comprises a threshold hover distance between the first portion of the body and the second portion of the body, and
wherein the computer readable code to modify the touch event parameter comprises computer readable code to modify the threshold hover distance in accordance with the velocity of the one of the first portion of the body of the user and the second portion of the body of the user.

19 . The system of claim 15 , wherein the computer readable code to modify the touch event parameter comprises computer readable code to modify a touch probability threshold value for determining that a touch event has occurred.

20 . The system of claim 15 , wherein the computer readable code to detect one or more touch events comprises computer readable code to:
detect a touch event in one or more additional frames of sensor data based on the modified touch event parameter; and determine that a last frame of the one or more frames of sensor data at which the touch is determined to occur is associated with a break touch event.
