Abstract

Claims (47)

1 . A method for detecting and responding to a user input in a device comprising a touch detection area and one or more determining sensors arranged to determine a position or relative movement of the user input at least outside the touch detection area, the method comprising:

detecting the user input at a perimeter of the touch detection area,

wherein the step of detecting user input at a perimeter of the touch detection area comprises receiving, from the touch detection area, information relating user activity in a direction toward a perimeter of the touch detection area;

activating the one or more determining sensors from a low energy state to a higher energy state, which is operative to determine position or relative movement of the user input, in response to detecting the user input at the perimeter of the touch detection area; and

causing a seamless transition between the touch detection area and an activity domain excluding the touch detection area, wherein causing the seamless transition comprises:

i. when the detected user input transits out from the perimeter of the touch detection area into the activity domain, causing the device to respond to the user input performed in the activity domain and of which the position or the relative movement is determined by the one or more determining sensors; and

ii. when the detected user input transits into the touch detection area from the activity domain, causing the device to respond to the user input performed in the touch detection area, and deactivating the one or more determining sensors from the higher energy state to the low energy state,

wherein the step of causing seamless transition between the touch detection area and the activity domain comprises:

determining device associated intrinsic reference points for the detected user activity, wherein the device associated intrinsic reference points are determined in a device reference system relative to the touch detection area of the device and the user activity is a touch activity performed on the touch detection area;

mapping individual ones of the extrinsic reference points in the activity domain, determined using the one or more determining sensors, to respective ones of the intrinsic reference points based on a predefined functional correspondence between off-screen and on-screen input modalities, wherein the extrinsic reference points are comprised in the activity domain located outside the touch detection area of the device;

tracking user activity relative to the extrinsic reference points in the activity domain;

identifying respective ones of the intrinsic reference points that are mapped to the extrinsic reference points corresponding to the tracked user activity; and

controlling an application in the device responsive to the identified respective ones of the intrinsic reference points that are mapped to the extrinsic reference points corresponding to the tracked user activity so as to effectuate a functionally continuous user interaction across the touch detection area and the activity domain.

2 . The method of claim 1 , wherein the device reference system comprises an intrinsic domain corresponding to the physical boundaries of the device and wherein the activity domain excludes the intrinsic domain.

3 . The method of claim 1 , further comprising associating the at least one intrinsic reference point to a respective finger or pointing device position on the touch detection area.

4 . The method of claim 3 , further comprising associating the at least one extrinsic reference point to a position of the respective finger or pointing device in the activity domain and activating the device to respond to user activity of the respective finger or pointing device.

5 . The method of claim 1 , further comprising:

enabling user control of one or more computer applications of the device based on user activity; and

presenting the user activity on a display connected to the touch detection area.

6 . The method of claim 1 , further comprising:

activating at least one connected device in response to detecting a user activity in the activity domain,

wherein the at least one connected device comprises a head mounted display (HMD) device with augmented reality capabilities to the device, and

wherein activating the at least one connected device comprises activating a menu of the HMD device, so that the menu becomes visible for a user in the HMD device.

7 . The method of claim 1 , wherein the device reference system is a one-, two- or three-dimensional reference system.

8 . The method of claim 1 , wherein the touch detection area is a touch pad connected to a display.

9 . The method of claim 1 , wherein the touch detection area is comprised in a touch panel.

10 . The method of claim 1 , wherein user activity comprises web-browsing, list scrolling, moving a cursor on the display, and activating functionality associated with computer applications.

11 . The method of claim 1 , wherein the step of causing the device to respond to user input from the touch detection area comprises:

receiving, from the touch detection area, information relating to renewed user activity in the touch detection area; and

de-activating the device from responding to user activity detected by the one or more motion detection sensors.

12 . A computer program product comprising a non-transitory computer readable medium, having thereon a computer program comprising program instructions, the computer program being loadable into a processing circuitry and configured to cause execution of the method according to claim 1 when the computer program is run by the processing circuitry.

13 . A device for detecting and responding to a user input, the device comprising a touch detection area, one or more determining sensors, and processing circuitry, wherein the processing circuitry is configured to perform operations comprising:

detecting the user input at a perimeter of the touch detection area,

wherein the step of detecting user input at a perimeter of the touch detection area comprises receiving, from the touch detection area, information relating user activity in a direction toward a perimeter of the touch detection area;

activating the one or more determining sensors from a low energy state to a higher energy state, which is operative to determine position or relative movement of the user input, in response to detecting the user input at the perimeter of the touch detection area; and

causing a seamless transition between the touch detection area and an activity domain excluding the touch detection area, wherein causing the seamless transition comprises:

i. when the detected user input transits out from the perimeter of the touch detection area into the activity domain, causing the device to respond to the user input performed in the activity domain and of which the position or the relative movement is determined by the one or more determining sensors; and
