Virtual Prisms Using Augmented Reality Displays

Patent Status

Brief Description

UC Berkeley researchers have developed a sophisticated method and apparatus for dynamically correcting ocular misalignment using pass-through augmented reality (AR) goggles. The system employs orientation sensors to track the user's gaze vectors and cameras to capture the surrounding environment in real time. A specialized processor calculates the specific magnitude of ocular misalignment for each eye and generates a computer-rendered version of the surroundings. By digitally shifting the images presented to each display based on these gaze vectors, the system acts as a "virtual prism," aligning the visual input with the user’s actual gaze to provide a clear, unified field of view. This technology offers a programmable, non-invasive alternative to traditional corrective lenses or surgery for individuals with complex vision impairments.

Suggested uses

• Clinical Vision Therapy: Providing a dynamic tool for treating strabismus (crossed eyes) and diplopia (double vision) without the need for physical prism lenses.

• Post-Surgical Rehabilitation: Assisting patients in adapting to visual changes following corrective eye surgeries through gradual digital adjustments.

• Precision HUDs for Operators: Enhancing situational awareness for pilots or heavy machinery operators by correcting minor ocular fatigue or misalignment in real time.

• Daily Vision Assistance: Creating wearable assistive devices for individuals with chronic ocular motility disorders to improve their quality of life.

• Diagnostic Tools: Using the integrated sensors to track and log the progression of eye movement disorders for ophthalmologists and optometrists.

Advantages

• Real-Time Adaptation: Unlike static physical prisms, this digital solution can adjust the degree of correction instantly based on where the user is looking.

• Non-Invasive Solution: Provides a significant visual improvement for complex alignment issues without the need for surgical intervention.

• Customized Multi-Eye Correction: Independently renders and adjusts images for each eye, allowing for precise correction of asymmetrical misalignments.

• Data-Driven Insights: The system can monitor and record gaze patterns and misalignment magnitudes, providing valuable diagnostic data for long-term care.

• Seamless Pass-Through Experience: Utilizes high-resolution cameras to ensure that the computer-generated surroundings feel natural and responsive to the user.
