Head-mounted display for performing ophthalmic examinations
First Claim
1. A head-mounted display (HMD) for conducting eye examinations, the HMD comprising:
- a frame that rests upon a head of a patient during use;
a left optical display surface configured to present digital images to a left eye;
a right optical display surface configured to present digital images to a right eye;
an image display system that is able tovisibly present digital images only to the left eye on the left optical display surface while visibly presenting nothing to the right eye on the right optical display surface,visibly present digital images only to the right eye on the right optical display surface while visibly presenting nothing to the left eye on the left optical display surfaces, andvisibly present digital images to the left eye and the right eye simultaneously on the left and right optical display surfaces,wherein the frame is designed such thatnothing can be seen by the right eye when digital images are presented only to the left eye, andnothing can be seen by the left eye when digital images are presented only to the right eye,so as to enable examining the left and right eyes individually;
an audio sensor configured to be able to autonomously record an audible response given by the patient during an eye examination;
a speaker configured to be able to autonomously pose an audible question that can be heard by the patient;
a speech recognition module configured to be able to autonomously identify one or more relevant keywords within the audible response; and
an analysis module configured to be able to autonomouslycompare the one or more relevant keywords to a master set of keywords known to represent a correct response to the audible question,determine that at least one relevant keyword does not match the master set of keywords, andadapt the eye examination in real time in response to the keywords.

Abstract
Various embodiments relate to systems and methods for performing eye examinations using an HMD that is able to present an image to each eye individually and then to both eyes simultaneously. Because the HMD, rather than a patient, controls conditions (e.g., glare, brightness) during the examination, test results are more likely to be accurate and reliable. In some embodiments, the HMD employs voice recognition to replicate the conversational exchange that would typically occur between the patient and the ophthalmologist or optometrist. The HMD may also be configured to change the visual environment experienced by the patient during testing. Further yet, the HMD, or another distinct computing system, may be configured to identify abnormal test results in real-time and, in some embodiments, the examination is modified accordingly. For example, tests scheduled to be performed during the examination can be modified or removed and new tests can be added.

13. A head-mounted display comprising:
-
a frame that rests upon a head of a patient during use; an optical display surface configured to present digital images; an image display system configured to generate digital images for display to the patient; a speaker configured to autonomously pose an audible question that can be heard by the patient; an audio sensor configured to autonomously record an audible response given by the patient during an eye examination; a processor; and a memory including instructions that, when executed by the processor, cause the processor to autonomously; identify one or more relevant keywords within the audible response; determine whether the audible response is indicative of a correct response to the audible question by comparing the one or more relevant keywords to a master set of keywords known to represent the correct response; determine that at least one relevant keyword does not match the master set of keywords; and adapt the eye examination in real time in response to the keywords. - View Dependent Claims (14, 15, 16, 17, 18)
