AUGMENTED REALITY DEVICE AND METHOD FOR DETECTING GAZE OF USER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17903616 titled 'AUGMENTED REALITY DEVICE AND METHOD FOR DETECTING GAZE OF USER
Simplified Explanation
The abstract describes a method for detecting the gaze of a user using an augmented reality (AR) device with a vision correction lens. Here are the key points:
- The method involves obtaining information about the vision correction lens that overlaps a light guide plate in the user's gaze direction.
- Light is emitted for gaze tracking towards a light reflector through a light emitter.
- The emitted light is reflected by the light reflector and directed towards the user's eye.
- A light receiver captures the light reflected by the user's eye.
- An eye image of the user is obtained based on the received light.
- The eye image is adjusted based on the lens characteristic information about the vision correction lens.
- Gaze information is then obtained based on the adjusted eye image.
Potential Applications
This technology has potential applications in various fields, including:
- Augmented reality (AR) devices: The method can be used to accurately track the gaze of users wearing AR devices, enhancing the user experience and enabling more precise interactions with virtual objects.
- Vision correction: By incorporating vision correction lenses into AR devices, users with visual impairments can benefit from improved vision while using AR applications.
- Eye-tracking research: The method can be utilized in eye-tracking studies to gather data on users' gaze patterns and behavior, providing valuable insights for various research fields.
Problems Solved
The method addresses several problems related to gaze detection and vision correction in AR devices:
- Accurate gaze tracking: By using a vision correction lens overlapping the light guide plate, the method ensures that the emitted light is properly directed towards the user's eye, resulting in more accurate gaze tracking.
- Vision correction integration: Incorporating vision correction lenses into AR devices eliminates the need for users to wear separate glasses or contact lenses, providing a more convenient and streamlined experience.
- Lens characteristic adjustment: Adjusting the eye image based on the lens characteristic information ensures that the gaze information obtained is precise and takes into account the user's specific vision correction needs.
Benefits
The method offers several benefits for users and developers of AR technology:
- Enhanced user experience: Accurate gaze tracking allows for more intuitive and natural interactions with virtual objects, improving the overall user experience.
- Improved vision: Users with visual impairments can enjoy improved vision while using AR applications, eliminating the need for additional vision correction aids.
- Streamlined design: Integrating vision correction lenses into AR devices simplifies the user's setup and eliminates the need for multiple devices or accessories.
- Precise gaze information: Adjusting the eye image based on lens characteristics ensures that the obtained gaze information is accurate and reliable, enabling more precise analysis and applications.
Original Abstract Submitted
A method, performed by an augmented reality (AR) device including a vision correction lens, of detecting a gaze of a user is provided. The method includes obtaining lens characteristic information about the vision correction lens arranged to overlap a light guide plate in a gaze direction of the user, emitting light for gaze tracking toward a light reflector through a light emitter, wherein the emitted light is reflected by the light reflector and then directed to an eye of the user, receiving a light reflected by the eye of the user through a light receiver, obtaining an eye image of the user based on the light received, adjusting the eye image of the user based on the lens characteristic information about the vision correction lens, and obtaining gaze information based on the adjusted eye image.
