Abstract: Various examples described herein relate to an HMD which comprises an HMD body positioned against a face of a user which includes an IMU to track user location data in an environment. The HMD also comprises a detachable headband assembly including a tracking feature module to construct a map of the environment based on the user location data. The HMD further includes a mechanical mount feature attaching the detachable headband assembly to the HMD body. The mechanical mount feature includes a connection interface to exchange the user location data between the IMU in the HMD body and the tracking feature module in the detachable headband assembly.

Abstract: Various examples described herein relate to a head mountable device (HMD) which comprises an input device to receive captured user data, a connection interface to exchange the user data with a host device, a privacy data switch to route the user data between the input device and the connection interface in the HMD, and a controller. The controller determines whether the user data is restricted data, directs the privacy data switch to block the exchange of the user data when it is determined that the user data is restricted data, and directs the switch to allow the exchange of the user data when it is determined that the user data is not restricted data.
