Title:
SOFT FOLLOW AND PITCH ANGLE EFFECTS FOR VR/AR INTERFACE
Document Type and Number:
WIPO Patent Application WO/2022/261013
Kind Code:
A3
Abstract:
The user interface of an electronic eyewear device tracks a user's head movement to keep the user interface in front of the user's eyes. A position forward vector, a rotation forward vector, and an up vector are defined to enable the system to individually adjust the rates of translation and rotation of the user interface as the user's head moves through space. By disconnecting the translation and rotation of the user interface from the head forward vector, the rates of translation and rotational movement of the user interface are separated from the rate of movement of the user's head to enable a delay in user interface movement relative to head movement for a more realistic VR/AR 3D presentation. The pitch angle is monitored to maintain the user interface in front of the user's eyes in the correct orientation even at difficult pitch angles such as straight up or straight down.
