A mobile electronic device is provided for use with a headset. A camera outputs digital pictures of a portion of the headset. A display device displays information for viewing by a user wearing the headset. A processor retrieves calibration parameters that characterize at least a pose of the camera relative to the display device, and processes a digital picture from the camera to identify a pose of an optically identifiable feature within the digital picture. A pose of the mobile electronic device is identified relative to the holder based on the identified pose of the optically identifiable feature within the digital picture and based on at least the pose of the camera relative to the display device as characterized by the calibration parameters. The processor controls where graphical objects are rendered on the display device based on the identified pose of the mobile electronic device relative to the holder.

Calibration of mobile electronic devices connected to headsets wearable by users

A method () of controlling a portable device comprising a first camera and a second camera facing in the same direction. The method comprises: selecting () one of the first camera and the second camera as a visualization camera; initializing () a localization algorithm having as an input image data representing images captured by one of the first camera and the second camera; determining () a respective focus score for at least one of the first camera and the second camera, said focus score indicating a focus quality of features identified from images captured by one of the respective camera; selecting (,) one of the first camera and the second camera as an enabled camera based on the at least one focus score; and generating a control signal configured to cause the selected camera to be enabled such that the image data representing images captured by the enabled camera are provided as the input to the localization algorithm.

Method of controlling a portable device and a portable device

A portable electronic device is used with a mixed reality (MR) headset. The MR headset includes a lens and a holder that retains the portable electronic device in a defined orientation relative to the lens. The portable electronic device includes a camera, a display device, and a processor. The camera outputs video frames and is arranged to view the lens. The display device is arranged to display information that is projected on the lens for reflection directly or indirectly toward the user's eyes and the camera. The processor performs operations that include processing the video frames from the camera to identify locations of at least one real-world feature, displaying information on the display device, and controlling at least one of the processing of the video frames and the displaying of the information on the display device to at least partially reduce occurrence in the video frames of the displayed information.
