Abstract

Disclosed herein are methods, devices, and systems that may enable a touch-based interface to receive dynamic user inputs based on pressure. An exemplary method may involve: (a) detecting a touch interaction including an increase in pressure greater than a first threshold pressure-increase followed by a reduction in pressure greater than a threshold pressure-reduction; and (b) responsive to detecting the touch interaction, initiating an operation based on a region of the touch-based interface that corresponds to the touch interaction, wherein the operation is associated with the touch interaction.

Claims

1. A system comprising:

a non-transitory computer-readable medium; and

program instructions stored on the non-transitory computer-readable medium and executable by at least one processor to;

receive an input signal corresponding to one or more touch interactions on a touch-based interface;

determine a pressure level of a given touch interaction at a given time;

detect a first touch interaction comprising a reduction in pressure level greater than a first threshold pressure-reduction;

responsive to detecting the first touch interaction, initiate a first operation based on a region of the touch-based interface that corresponds to the first touch interaction;

detect a second touch interaction comprising an increase in pressure level greater than a first threshold pressure-increase followed by a reduction in pressure level greater than a second threshold pressure-reduction; and

responsive to detecting the second touch interaction, initiate a second operation based on a region of the touch-based interface that corresponds to the second touch interaction.

2. The system of claim 14:

wherein the increase in pressure level greater than the first threshold pressure-increase comprises an increase in the pressure level by at least a second predetermined percentage.

3. The system of 14, wherein the reduction in pressure level greater than the second threshold pressure-reduction comprises a decrease in the pressure level by at least a third predetermined percentage.

4. The system of claim 14, wherein the system further comprises a head-mounted display, wherein the head-mounted display comprises at least one lens element, and wherein a graphic display is integrated into the at least one lens element.

5. The system of claim 17, wherein the touch-based interface is attached to the head-mounted display.

6. The system of claim 18, wherein the head-mounted display further comprises at least one extending side-arm, and wherein the touch-based interface is attached to one of the at least one extending side-arm.

7. A computer-implemented method comprising:

detecting a touch interaction including an increase in pressure greater than a first threshold pressure-increase followed by a reduction in pressure greater than a threshold pressure-reduction; and

responsive to detecting the touch interaction, initiating an operation based on a region of the touch-based interface that corresponds to the touch interaction, wherein the operation is associated with the touch interaction.

8. The method of claim 21, further comprising:

detecting another touch interaction on a touch-based interface, wherein the other touch interaction is a tap interaction comprising a reduction in pressure greater than a threshold pressure-reduction; and

responsive to detecting the tap interaction, initiating an operation based on a region of the touch-based interface that corresponds to the tap interaction, wherein the operation is associated with the tap interaction.

9. A computer-implemented method comprising:

detecting a first touch interaction comprising contact with a given region of the touch-based interface for a given period of time;

determining whether or not the given period of time is less than a threshold period of time;

if the given period of time is less than the threshold period of time, then initiating a first operation based on the region of the touch-based interface that is contacted; and

if the given period of time is greater than the threshold period of time, then initiating a second operation based on the region of the touch-based interface that is contacted.
