Abstract

An embodiment takes the form of a computer-implemented method comprising causing a field-sequential color display of a wearable computing device to initially operate in a first color space; and based at least in part on data from one or more sensors of the wearable computing device, detecting movement of the wearable computing device that is characteristic of color breakup perception. The method further comprises, in response to detecting the movement that is characteristic of color breakup perception, causing the field-sequential color display to operate in a second color space.

Claims

1. A computer-implemented method comprising:

causing a field-sequential color display of a wearable computing device to initially operate in a first color space;

based at least in part on data from one or more sensors of the wearable computing device, detecting movement of the wearable computing device;

determining that the movement of the wearable computing device corresponds to an identified type of persistent physical activity that is characteristic of color breakup perception within the field-sequential color display of the wearable computing device; and

in response to determining that the movement of the wearable computing device corresponds to the identified type of persistent physical activity that is characteristic of color breakup perception, causing the field-sequential color display of the wearable computing device to switch from the first color space to a second color space, wherein the second color space is chosen in order to mitigate color breakup perception resulting from operation of the wearable computing device in the first color space; and

continuing to operate the wearable computing device in the chosen second color space during the identified type of persistent physical activity.

2. The method of claim 1, wherein causing the field-sequential color display of the wearable computing device to switch from the first color space to the second color space comprises causing the field-sequential display to switch from a polychromatic color space to a monochromatic color space in order to mitigate color breakup perception resulting from operation of the wearable device in the polychromatic color space.

3. The method of claim 2, wherein the polychromatic color space comprises a red-green-blue (RGB) color space.

5. The method of claim 1, wherein the second color space is a polychromatic color space.

6. The method of claim 5, wherein the polychromatic color space is a color space selected from a group of color spaces consisting of a white-red color space and a cyan-magenta-yellow color space.

7. The method of claim 1, wherein the field-sequential color display is initially operating at a first frame rate, the method further comprising:

in further response to determining that the movement of the wearable computing device corresponds to the identified type of persistent physical activity that is characteristic of color breakup perception, causing the field-sequential color display to operate at a second frame rate.

8. The method of claim 1, wherein the movement sensor is a sensor selected from a group of sensors consisting of an accelerometer and a gyroscope.

20. The method of claim 1, wherein determining that the movement of the wearable computing device corresponds to the identified type of persistent physical activity that is characteristic of color breakup perception comprises detecting an amount of movement of the field-sequential color display that is greater than a threshold amount of movement.

21. The method of claim 1, wherein the identified type of persistent physical activity that is characteristic of color breakup perception comprises an athletic activity.

22. The method of claim 1, wherein the identified type of persistent physical activity that is characteristic of color breakup perception comprises at least one of running, jogging, eating, and riding a bike.
