Abstract
One example provides a head-mounted display (HMD) device comprising a display system, a logic subsystem, and a storage subsystem comprising instructions executable by the logic subsystem. The instructions are executable to project images at a first frame rate using the display system, detect a change in a stimulus attribute of the images that modifies a critical flicker fusion (CFF) threshold of a human eye, and in response, adjust a frame rate of the display system to project the images at a second frame rate.

A head-mounted display (HMD) device comprising:
- a display system;
- a logic subsystem;
- and
- a storage subsystem comprising instructions executable by the logic subsystem to
- project images at a first frame rate using the display system,
- detect a change in a stimulus attribute of the images that modifies a critical flicker fusion (CFF) threshold of a human eye, the stimulus attribute being a characteristic of the images that is discernable by the human eye, wherein the stimulus attribute is one of a plurality of stimulus attributes,
- in response, adjust a frame rate of the display system to project the images at a second frame rate,
- receive an input indicating that the HMD device has entered a power saving mode, and
- in response, modulate a selected stimulus attribute of the plurality of stimulus attributes of the images to decrease the CFF threshold.
On a head-mounted display (HMD) device comprising a display system, a method comprising:
- projecting images at a first frame rate using the display system,
- detecting a change in a stimulus attribute of the images that modifies a critical flicker fusion (CFF) threshold of a human eye, the stimulus attribute being a characteristic of the images that is discernable by the human eye, wherein the stimulus attribute is one of a plurality of stimulus attributes,
- in response, adjusting a frame rate of the display system to project the images at a second frame rate,
- receiving an input indicating that the HMD device has entered a power saving mode, and
- in response, modulating a selected stimulus attribute of the plurality of stimulus attributes of the images to decrease the CFF threshold.
