DEVICE AND METHOD FOR CORRECTING USER'S VISION AND PERFORMING CALIBRATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17436465 titled 'DEVICE AND METHOD FOR CORRECTING USER'S VISION AND PERFORMING CALIBRATION
Simplified Explanation
The patent application describes a device and method for correcting the vision of a user and performing calibration using an augmented reality device. Here are the key points:
- The method involves calibrating the gaze tracking sensor of an augmented reality device.
- The device outputs a preset-sized character through a waveguide.
- It obtains input from the user based on the displayed character.
- The device also detects gaze information through the gaze tracking sensor.
- The method compares the displayed character with the user's input.
- Based on the comparison result, it determines the refractive power of the varifocal lens of the augmented reality device.
Potential applications of this technology:
- Correcting vision and providing a personalized viewing experience through augmented reality devices.
- Improving the accuracy and effectiveness of gaze tracking sensors in augmented reality systems.
- Enhancing the user experience by ensuring precise calibration of the device.
Problems solved by this technology:
- Inaccurate calibration of gaze tracking sensors can lead to incorrect eye-tracking data and affect the overall performance of augmented reality systems.
- Varifocal lenses need to be properly adjusted to provide optimal vision correction for users.
Benefits of this technology:
- Provides a more accurate and personalized vision correction experience for users of augmented reality devices.
- Improves the performance and reliability of gaze tracking sensors in augmented reality systems.
- Enhances the overall user experience by ensuring precise calibration and optimal vision correction.
Original Abstract Submitted
Provided are a device and method for correcting the vision of a user and performing calibration. A method, performed by an augmented reality device, of performing gaze tracking sensor calibration based on a gaze of a user includes outputting at least one first character in a preset size through a waveguide of the augmented reality device, obtaining at least one first input for the at least one first character, obtaining at least one piece of first gaze information detected through a gaze tracking sensor of the augmented reality device at a time point at which the at least one first input is obtained, comparing the at least one first character with the at least one first input, and determining a first refractive power to be a refractive power of the varifocal lens of the augmented reality device, based on a result of the comparing.
