EYEWEAR WITH INTER-PUPILLARY DISTANCE ESTIMATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240341591 titled 'EYEWEAR WITH INTER-PUPILLARY DISTANCE ESTIMATION
The eyewear device described in the patent application includes a sensor that measures the deformation of the eyewear frame to estimate the inter-pupillary distance (IPD) of the user. The sensor is also used to determine the head breadth (HB) of the user, which helps in estimating the IPD accurately. A processor then displays an image on the eyewear display based on the estimated IPD to enhance the virtual object rendering for an improved augmented reality (AR) viewing experience, while reducing vergence accommodation mismatch (VAM). User profile data, such as age and gender, can be utilized to generate a more precise estimated IPD of the user.
- Sensor measures deformation of eyewear frame
- Estimates inter-pupillary distance (IPD) of user
- Determines head breadth (HB) of user
- Processor displays image on eyewear display based on estimated IPD
- Enhances virtual object rendering for improved AR experience
- Reduces vergence accommodation mismatch (VAM)
- User profile data used to generate accurate estimated IPD
Potential Applications: - Augmented reality (AR) applications - Virtual reality (VR) applications - Eyewear customization based on user's IPD - Optometry and vision care
Problems Solved: - Inaccurate IPD estimation in eyewear devices - Vergence accommodation mismatch (VAM) in AR/VR experiences
Benefits: - Improved AR/VR viewing experience - Customized eyewear for better fit and comfort - Enhanced accuracy in IPD estimation
Commercial Applications: Title: Enhanced Augmented Reality Eyewear for Accurate IPD Estimation This technology can be used in the development of advanced AR/VR glasses for various industries such as gaming, healthcare, and education. It can also be integrated into optometry practices for precise IPD measurements.
Questions about the technology: 1. How does the sensor in the eyewear device measure the deformation of the frame? 2. What are the potential implications of using user profile data to estimate the IPD accurately?
Original Abstract Submitted
an eyewear device including a sensor used to measure deformation of an eyewear frame to estimate an inter-pupillary distance (ipd) of an eyewear user. the sensor is used to determine head breadth (hb) of the user and to estimate the ipd of the user. a processor displays an image on a display of the eyewear as a function of the estimated ipd to improve virtual object rendering for an improved augmented reality (ar) viewing experience while reducing vergence accommodation mismatch (vam). user profile data, such as age and gender, can be used to generate a more accurate estimated ipd of the user.
