Abstract

Embodiments that relate to communicating to a user of a head-mounted display device an estimated quality level of a world-lock display mode are disclosed. For example, in one disclosed embodiment a sensor data is received from one or more sensors of the device. Using the sensor data, an estimated pose of the device is determined. Using the estimated pose, one or more virtual objects are displayed via the device in either the world-lock display mode or in a body-lock display mode. One or more of input uncertainty values of the sensor data and pose uncertainty values of the estimated pose are determined. The input uncertainty values and/or pose uncertainty values are mapped to the estimated quality level of the world-lock display mode. Feedback of the estimated quality level is communicated to a user via device.
