Abstract
In described techniques, a depth of an object may be determined with respect to a head-mounted device (HMD). A gaze duration with respect to the object may be determined, relative to a gaze duration threshold. Then, based on the depth and on the gaze duration exceeding the gaze duration threshold, virtual content may be rendered at a virtual depth with respect to the HMD that is different than the depth.
Claims18
A computer program product, the computer program product being tangibly embodied on a non-transitory computer-readable storage medium and comprising instructions that, when executed by at least one computing device, are configured to cause the at least one computing device to:
- determine a depth of an object with respect to a head-mounted device (HMD);
- determine a first duration of a first gaze with respect to the object, relative to a first threshold;
- render, based on the depth and on the first duration relative to the first threshold, virtual content at a virtual depth with respect to the HMD that is different than the depth;
- determine a second duration of a second gaze with respect to the virtual content at the virtual depth, relative to a second threshold;
- and
- render additional virtual content, based on the second duration failing to exceed the second threshold.
A head-mounted device (HMD) comprising:
- at least one frame for positioning the HMD on a face of a user;
- at least one display;
- at least one processor;
- and
- at least one memory, the at least one memory storing a set of instructions, which, when executed, cause the at least one processor to:
- determine a depth of an object with respect to a head-mounted device (HMD);
- determine a first duration of a first gaze with respect to the object, relative to a first threshold;
- render, using the at least one display and based on the depth and on the first duration relative to the first threshold, virtual content at a virtual depth with respect to the HMD that is different than the depth;
- determine a second duration of a second gaze with respect to the virtual content at the virtual depth, relative to a second threshold;
- and
- render additional virtual content, based on the second duration failing to exceed the second threshold.
