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.
Claims15
A head mountable display (HMD) comprising:
- an HMD body positioned against a face of a user which includes an inertial measurement unit (IMU) to track user location data in an environment;
- a detachable headband assembly including a tracking feature module to construct a map of the environment based on the user location data;
- and
- a mechanical mount feature attaching the detachable headband assembly to the HMD body, wherein 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.
An augmented reality (AR) device comprising:
- an optical engine;
- an inertial measurement unit (IMU) to measure user position data;
- a mechanical mount feature to attach the AR device to a removeable head strap device;
- and
- a communication interface to transfer the user position data to the removeable head strap device, wherein the removeable head strap device includes a tracking feature module for constructing a map of a user environment based on the user position data.
A removeable head strap device comprising:
- a camera to capture image data of a user environment;
- a connection interface to receive the user position data from an inertial measurement unit (IMU) in a connectable Augmented Reality (AR) device;
- and
- a simultaneous localization and mapping (SLAM) module to process the user position data and the captured image data to construct a map of the environment.
