Lens Distance Test for Head-Mounted Display Devices - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240105046 titled 'Lens Distance Test for Head-Mounted Display Devices
Simplified Explanation
The patent application describes systems and methods for performing a lens distance test in head-mounted displays (HMDs) to determine the distance between a user's eye and the lens of the HMD. The HMD captures eye images to determine the eye's pose and calculate the distance from the cornea to the lens. Alerts are generated if the distance is incorrect, prompting adjustments for better distancing and user experience.
- The HMD captures eye images to determine the eye's pose.
- The distance from the cornea to the lens is calculated based on the eye's pose.
- Alerts are generated if the distance is incorrect, prompting adjustments for better distancing and user experience.
- The lens distance test can be repeated during a user session to monitor and reevaluate the lens distance.
Potential Applications
This technology can be applied in various fields such as virtual reality, augmented reality, gaming, medical training, and simulation.
Problems Solved
This technology helps in reducing the risk of eye injury and improving the overall user experience by ensuring the correct distance between the user's eye and the lens of the HMD.
Benefits
The benefits of this technology include enhanced user comfort, improved visual experience, and reduced eye strain or potential injuries.
Potential Commercial Applications
Commercial applications of this technology include VR/AR devices, gaming headsets, medical training simulators, and other HMD products.
Possible Prior Art
Prior art in this field may include existing methods for measuring eye-lens distance in optical devices or medical equipment.
Unanswered Questions
1. How does the system account for variations in eye anatomy among different users? 2. Are there any potential privacy concerns related to capturing and analyzing eye images for this purpose?
Original Abstract Submitted
systems and methods are disclosed to enable performance of a lens distance test in head-mounted displays (hmds) to determine the distance between a user's eye and a lens of the hmd (e.g. the display lens in a virtual or augmented reality device). in embodiments, the hmd is configured to determine a current pose of the eye based on a series of captured eye images. the pose information is used to determine the distance from the apex of the cornea to a closest point on the lens. if the determined distance is too small or too large, an alert or notification is generated instructing to adjust the hmd or change the light seal to achieve better distancing, in order to reduce the risk of eye injury and/or improve user experience. in embodiments, the lens distance test may be repeated during a user session to reevaluate and/or monitor the lens distance.
