World-locked display quality feedback

A head-mounted display device operatively connected to a computing device, the head-mounted display device comprising:

• a tracking system executed by a processor of the computing device, the tracking system configured to:
• receive sensor data from one or more sensors of the head-mounted display device;
• using the sensor data, determine an estimated pose of the head-mounted display device;
• determine one or more of input uncertainty values of the sensor data and pose uncertainty values of the estimated pose;
• map one or more of the input uncertainty values and the pose uncertainty values to an estimated quality level of a world-lock display mode in which a position of one or more virtual objects appears to be fixed relative to real-world objects viewable through the head-mounted display device;
• and
• communicate feedback to a user via the head-mounted display device of the estimated quality level;
• and
• a display program executed by a processor of the computing device, the display program configured to display the one or more virtual objects using the estimated pose in either the world-lock display mode or in a body-lock display mode in which the position of each of the virtual objects appears to be fixed relative to the user of the head-mounted display device.

A method for communicating to a user of a head-mounted display device an estimated quality level of a world-lock display mode in which a position of one or more virtual objects appears to be fixed relative to real-world objects viewable through the head-mounted display device, the method comprising:

• receiving sensor data from one or more sensors of the head-mounted display device;
• using the sensor data, determining an estimated pose of the head-mounted display device;
• using the estimated pose, displaying the one or more virtual objects via the head-mounted display device in either the world-lock display mode or in a body-lock display mode in which the position of each of the virtual objects appears to be fixed relative to the user of the head-mounted display device;
• determining one or more of input uncertainty values of the sensor data and pose uncertainty values of the estimated pose;
• mapping one or more of the input uncertainty values and the pose uncertainty values to the estimated quality level of the world-lock display mode;
• and
• displaying one or more graphical representations of the estimated quality level to the user via the head-mounted computing device.
