Abstract: Techniques for operating a depth sensor are discussed. A first sequence of operation steps and a second sequence of operation steps can be stored in memory on the depth sensor to define, respectively, a first depth sensing mode of operation and a second depth sensing mode of operation. In response to a first request for depth measurement(s) according to the first depth sensing mode of operation, the depth sensor can operate in the first mode of operation by executing the first sequence of operation steps. In response to a second request for depth measurement(s) according to the second depth sensing mode of operation, and without performing an additional configuration operation, the depth sensor can operate in the second mode of operation by executing the second sequence of operation steps.

Abstract: Techniques for determining a user's IPD are described. A first stimulus is displayed on a first display, and a second stimulus is displayed on a second display. A stimulus separation distance is a distance that exists between the first and second stimuli. The stimulus separation distance is progressively increased by progressively moving, in opposing directions relative to one another, the first and second stimuli. While that distance is being progressively increased, at least one of the user's eyes is tracked. While the distance is being progressively increased, a change in a rate of eye movement for the user's eye is detected. When the change is detected, a value for the stimulus separation distance is recorded. The recorded value is set as a baseline for the user's IPD.

Abstract: A head mounted display system can process images by assessing relative motion between the head mounted display and one or more features in a user's environment. The assessment of relative motion can include determining whether the head mounted display has moved, is moving and/or is expected to move with respect to one or more features in the environment. Additionally or alternatively, the assessment can include determining whether one or more features in the environment have moved, are moving and/or are expected to move relative to the head mounted display. The image processing can further include determining one or more virtual image content locations in the environment that correspond to a location where renderable virtual image content appears to a user when the location appears in the display and comparing the one or more virtual image content locations in the environment with a viewing zone.

Abstract: Techniques for adjusting a separation distance between stimuli generated by a pair of rendering cameras to accommodate an IPD of a user who is viewing the stimuli are disclosed. The IPD of the user is determined. A first stimulus, which is generated by a first one of the rendering cameras, is accessed. A second stimulus, which is generated by a second one of the rendering cameras, is accessed. The separation distance between the first stimulus and the second stimulus is determined. The separation distance is then reduced, resulting in the separation distance being narrower than the user's IPD. The first and second stimuli are then displayed in accordance with the reduced separation distance.

Abstract: A system and method for operating a depth sensor. A configuration operation can be performed by storing a first sequence of operation steps which define a first depth sensing mode of operation, and a second sequence of operation steps which define a second depth sensing mode of operation, in the memory. In response to a first request for depth measurements according to the first depth sensing mode of operation, the depth sensor can be operated in the first mode of operation by causing it to execute the first sequence of operation steps. In response to a second request for depth measurements according to the second depth sensing mode of operation, and without performing an additional configuration operation, the depth sensor can be operated in the second mode of operation by causing it to execute the second sequence of operation steps.

Abstract: Techniques for correcting a vertical angular image misalignment in stereoscopic images generated by an extended reality (ER) system are disclosed. A hologram is identified. This hologram is displayed in a scene of the ER system. A spatial frequency of the hologram is determined. A determination is made that the spatial frequency exceeds a spatial frequency threshold. The spatial frequency of the hologram is reduced until the spatial frequency is below the spatial frequency threshold. Such an operation results in a compensation being performed for a vertical angular image misalignment that exists between the stereoscopic images.

Abstract: Techniques for linking a distance used during a reprojection operation with a focal length of a sensing system are disclosed. As a result, modifications to the focal length result in corresponding modifications to the distance. A focal length of the sensing system is adjusted. An image generated by the sensing system is accessed. A particular distance is selected based on the adjusted focal length of the sensing system. The distance is used to reproject the image.

Abstract: Techniques for facilitating calibration of an IPD for an ER system are disclosed. A current IPD setting for the ER system is determined. An object in a scene is selected. A first distance between the ER system and the object is determined. A hologram is generated, where this hologram includes at least one boundary region that corresponds to at least one boundary region of the object. The hologram is displayed in the scene. The hologram is displayed based on the current IPD setting for the ER system. User input adjusts the current IPD setting such that a new IPD setting is provided to the ER system. The hologram is displayed in the scene based on the new IPD setting. Based on the new IPD setting, the hologram is caused to align with the object, thereby calibrating the IPD setting.

Abstract: A power profile library includes a plurality of power profiles with each power profile having a plurality of maximum clock speeds for respective processors. The maximum clock speeds of each power profile are selected to limit a maximum amount of heat per unit time generated by the processors in combination. A developer computer system selects sections of an eventual application for a consumer device and a target intent for each section. A power profile lookup uses the target intents to determine a power profile for each section.

Abstract: Examples are disclosed that relate to methods, computing devices, and head-mounted display (HMD) devices for regulating a surface temperature of a device. In one example, a method comprises determining the surface temperature of a surface of the device, determining an energy accumulator value indicating cumulative energy received by a user via the surface of the device, and using a dynamic temperature limit function to calculate a temperature limit as a function of the energy accumulator value. The method also comprises comparing the surface temperature to the temperature limit. When the surface temperature has not reached the temperature limit, the method comprises incrementing the energy accumulator value. When the surface temperature has reached the temperature limit, the method comprises initiating a thermal mitigation action to cool the surface.
