Method and device for delivering visual stimuli with head mounted display during vision training

Abstract

A head mounted display for diagnosing or training vision of a subject. In one embodiment, the head mounted display includes a first display that presents a first visual image to a first eye of the subject in an identified position of regard with respect to a specified zone in the field of view of the subject. This embodiment may also include a second display that presents a second visual image to a second eye of the subject in an identified position of regard with respect to a specified zone in the field of view of the subject. This embodiment may also include an anterior support section coupled to the first and second displays, the anterior support section orienting the display in front of the eyes of the subject and may also include a posterior support section coupled to the anterior support section.

Description

[0001] This application claims priority to U.S. Provisional Patent Application Serial No. 60 / 666,455, filed March 30, 2005, and U.S. Provisional Patent Application Serial No. 60 / 763,589, filed January 31, 2006, both of which Both applications are hereby incorporated by reference in their entirety. technical field [0002] The present invention relates to systems and methods for providing vision training to subjects, including patients with vision impairments. In particular, the invention is directed to providing visual stimuli to a head mounted display worn by the subject as part of visual training. Background technique [0003] The purpose of therapeutic vision training is to improve visual function in visually impaired patients by stimulating the patient's visual system with visual stimuli. For example, the introduction of visual stimuli to the transition and / or unimpaired vision regions of the human visual system can improve a subject's vision as described in U.S. Patent...

AI Technical Summary

Problems solved by technology

A person's natural tendency to move after remaining in an unsupported, fixed position for a substantial period of time may result in a misalignment of the visual stimulus relative to the subject's field of view

This misalignment can limit the effectiveness of training sessions

Even if the subject attempts to fix the position of his head relative to the monitor, identifying the correct position can be difficult, especially for individual subjects outside of the clinic

Additionally, it can take a significant amount of time to properly align the relative position of the monitor with the field of view of the subject
