AUGMENTED REALITY DISPLAY WITH FRAME MODULATION FUNCTIONALITY

Smart overview of the Invention

The patent application describes a head-mounted display (HMD) system that processes images by evaluating motion between the display and environmental features. This involves determining if the display or environmental features have moved or are expected to move. The system also identifies virtual image content locations in the environment, comparing them with a viewing zone to enhance user experience in augmented reality (AR) settings.

Field and Background

The technology pertains to AR, VR, and MR systems, focusing on performance modulation and power-saving in wearable display devices. These systems present digital images as part of the real world, merging virtual and actual environments. The challenge is creating a seamless visual experience that feels natural to the user, which this invention aims to address through advanced image processing techniques.

System Components

The HMD includes a frame-supported display projecting virtual images into the user's eyes while allowing real-world visibility. It incorporates a camera for environmental imaging at adjustable frame rates. Processing electronics assess motion relative to environmental features, adjusting the camera's frame rate or image processing workload based on this assessment, thereby optimizing performance and power usage.

Detailed Functionality

The HMD can render 3D objects using a world map of the environment. It adjusts rendering based on eye movement and head position changes, maintaining realistic presentations even if the device shifts. The system uses inward-facing cameras to track periocular features for accurate image projection, ensuring fit and comfort while optimizing power distribution among device components.

Power Management

The HMD employs sensors to detect whether it is being worn, adjusting modes accordingly to save power. Outward-facing cameras adapt their frame rates based on environmental dynamics and user actions, balancing imaging quality with energy efficiency. This dynamic adjustment ensures optimal performance while conserving battery life within varying usage scenarios.
