Problems solved by technology

This technique can be acceptable for certain applications, but has limitations.
One is that high user skill may be required.
However, a user controlling a drone with a joystick or other manual interface while watching the camera view on an HMD can find the experience unsettling.
However, technical issues in this technique can make it unsuitable for various applications.
This might be unsettling or otherwise unsatisfactory for the user.
However, the camera 108 lags the user's head because of system delays as described above.

Embodiment Construction

[0017]In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the disclosed subject matter. It will be apparent to persons of ordinary skill, upon reading this description, that various aspects can be practiced without such details. As will be understood by persons of skill upon reading this disclosure, benefits and advantages provided and enabled by disclosed subject matter and its various implementations can include, but are not limited to, a solution to the technical problem arising in head motion control of drone supported or other remote articulated or movable cameras, arising from mismatches between the user's head motion and images on the user's head-mounted display (HMD). Technical features include 1:1 matching the motion of the camera on the drone to the user's head movement, and “1:1” includes tracking the head motion and using a result to render at least a portion of the camera image...

Abstract

Tracking a user head position detects a change to a new head position and, in response, a remote camera is instructed to move to a next camera position. A camera image frame, having an indication of camera position, is received from the camera. Upon the camera position not aligning with the next camera position, an assembled image frame is formed, using image data from past views, and rendered to appear to the user as if the camera moved in 1:1 alignment with the user's head to the next camera position.

Description

TECHNICAL FIELD[0001]This disclosure relates generally to telepresence via remote user control of movable cameras, and, more particularly, to matching of remote user head motion and rotation to the video presented to the user.BACKGROUND[0002]A user can operate a joystick or other manual interface to remotely control a camera equipped drone, while watching the drone's camera image on a display. This technique can be acceptable for certain applications, but has limitations. One is that high user skill may be required. Another is that for some applications and users, watching the camera view on a head mounted display (HMD) may be preferable. However, a user controlling a drone with a joystick or other manual interface while watching the camera view on an HMD can find the experience unsettling. This can be due to changing orientation of the view on the HMD without any inner ear sense of a corresponding changing of head orientation.[0003]The HMD can be provided with a controller or senso...
