AUGMENTED REALITY DEVICE FOR ADJUSTING FOCUS REGION ACCORDING TO DIRECTION OF USER'S VIEW AND OPERATING METHOD OF THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240036288 titled 'AUGMENTED REALITY DEVICE FOR ADJUSTING FOCUS REGION ACCORDING TO DIRECTION OF USER'S VIEW AND OPERATING METHOD OF THE SAME

Simplified Explanation

The abstract describes an augmented reality (AR) device that includes a variable focus lens. The focal length of the lens can be changed by adjusting its refractive power and the position of a focus adjustment region. This adjustment is based on the direction of the user's view, which is determined using an eye tracker. The device can obtain an eye vector indicating the user's view direction, adjust the refractive power of a first focus adjustment region of a first variable focus lens to change the focal length for displaying a virtual image, and complementarily adjust the refractive power of a second focus adjustment lens based on the adjusted refractive power of the first focus adjustment region.

  • The AR device includes a variable focus lens that can change its focal length by adjusting refractive power and the position of a focus adjustment region.
  • The user's view direction is determined using an eye tracker, and the device adjusts the refractive power of the lens and the position of the focus adjustment region accordingly.
  • The device can display virtual images with different focal lengths based on the user's view direction.
  • The refractive power of the first focus adjustment region is adjusted to change the focal length for displaying virtual images.
  • The refractive power of the second focus adjustment lens is complementarily adjusted based on the refractive power of the first focus adjustment region.

Potential Applications

  • Augmented reality devices with variable focus lenses can enhance the user experience by providing clear and focused virtual images.
  • This technology can be used in various industries, such as gaming, education, healthcare, and engineering, to create more immersive and realistic augmented reality experiences.
  • It can also be applied in training simulations, remote assistance, and visualization of complex data.

Problems Solved

  • Traditional augmented reality devices have fixed focal lengths, which can cause discomfort and eye strain for users.
  • This technology solves the problem of fixed focal lengths by providing a variable focus lens that can be adjusted based on the user's view direction.
  • By dynamically changing the focal length, the device ensures that virtual images appear clear and focused, reducing eye fatigue and improving user comfort.

Benefits

  • The variable focus lens allows for a more natural and immersive augmented reality experience.
  • Users can view virtual images with different focal lengths, making them appear more realistic and integrated with the real world.
  • By adjusting the focal length based on the user's view direction, the device provides optimal visual quality and reduces eye strain.
  • This technology improves the usability and comfort of augmented reality devices, making them more suitable for extended use.


Original Abstract Submitted

an augmented reality (ar) device including a variable focus lens of which a focal length may be changed by adjusting refractive power and adjusting the position of a focus adjustment region of the variable focus lens according to a direction of the user's view. the ar device may obtain an eye vector indicating a direction of the user's view using an eye tracker, adjust a refractive power of a first focus adjustment region of a first variable focus lens to change a focal length for displaying a virtual image, and complementarily adjust a refractive power of a second focus adjustment lens with respect to the adjusted refractive power of the first focus adjustment region.
