LAST-LEVEL PROJECTION METHOD AND APPARATUS FOR VIRTUAL AND AUGMENTED REALITY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240046544 titled 'LAST-LEVEL PROJECTION METHOD AND APPARATUS FOR VIRTUAL AND AUGMENTED REALITY

Simplified Explanation

The patent application describes an apparatus and method for efficient image reprojection in a virtual reality system. It involves collecting motion data from sensors, rendering image frames, generating motion transform data to adjust the frames, performing in-line reprojection, and displaying the reprojected frames.

  • Sensor interface collects motion data from one or more sensors during a virtual reality session.
  • Graphics circuitry executes graphics program code to render an image frame during the virtual reality session.
  • Processor generates motion transform data using the motion data, specifying how the image frame is to be adjusted prior to display.
  • Reprojection engine performs an in-line reprojection of the frame using the motion transform data to generate a reprojected image frame.
  • Display circuitry displays the reprojected frame.

Potential applications of this technology:

  • Virtual reality gaming: The efficient image reprojection can enhance the immersive experience in virtual reality games by reducing motion sickness and improving visual quality.
  • Virtual training simulations: This technology can be used in various training simulations, such as flight simulators or medical training, to provide realistic visuals and accurate motion tracking.
  • Architectural visualization: Architects and designers can use this technology to create virtual walkthroughs of their designs, allowing clients to experience the spaces before they are built.

Problems solved by this technology:

  • Motion sickness: By adjusting the image frames based on motion data, this technology can help reduce motion sickness commonly experienced in virtual reality.
  • Visual quality: The reprojection technique improves the visual quality of the image frames by minimizing artifacts and distortions caused by head movements.

Benefits of this technology:

  • Enhanced user experience: The efficient image reprojection improves the overall virtual reality experience by providing smoother visuals and reducing motion sickness.
  • Realistic simulations: The accurate motion tracking and reprojection enable more realistic simulations, making virtual reality applications more immersive and effective.
  • Cost-effective: By optimizing the rendering process and utilizing motion transform data, this technology can potentially reduce the computational resources required for virtual reality systems.
