Interactive System for Vision Assessment and Correction

Abstract

Systems and methods for assessing vision and correcting vision problems are provided. A head-mountable virtual reality display controlled via a computing device can be worn by a user to display virtual reality images to the user. The images can be displayed as part of an interactive and engaging activity that can be used to determine a value of a certain parameter of the user's eyes. The activity can also be intended as a treatment procedure during which user's eyes are trained to perceive objects having certain properties that unassisted eyes of the user are normally not able to perceive. User input is acquired to determine user's perception of the displayed virtual reality images. The computing device can be a smartphone configured to perform the vision tests or treatment under control of a remote computing device operated by a trained clinician.

         29 . A system for vision assessment or correction, the system comprising:
 computing hardware configured to perform operations comprising:   displaying a virtual reality environment on a virtual reality display of a head-mountable virtual reality device, the virtual reality environment comprising a first portion of an object displayed to a user wearing the head-mountable virtual reality device such that the first portion is presented to a right eye of the user, and a second portion of the object displayed to the user wearing the head-mountable virtual reality such that the second portion is presented to a left eye of the user, wherein the second portion is displayed at a distance from the first portion;   receiving user input with respect to the first and second portions, the user input indicative of adjustment of at least one property of the first and second portions;   adjusting the at least one property of the first and second portions on the virtual reality display and in the virtual reality environment in response to the received user input;   iteratively performing the receiving and adjusting steps until a user input is received indicating that the user perceives the first and second portions merged into a single representation of the object; and   determining alignment of the right and left eyes of the user based on the user input received during the iterative performance of the receiving and adjusting steps.   
     
     
         30 . The system of  claim 29 , wherein determining alignment of the right and left eyes of the user comprises determining an angle of binocular disparity. 
     
     
         31 . The system of  claim 29 , wherein the at least one property of the first and second portions comprises a position of each of the first and second portions. 
     
     
         32 . The system of  claim 30 , wherein receiving the user input comprises receiving user input indicative of movement of the first and second portions. 
     
     
         33 . The system of  claim 32 , wherein the movement comprises at least one of a linear movement and rotation of the first and second portions. 
     
     
         34 . The system of  claim 29 , wherein the first portion differs from the second portion by a predetermined amount of binocular disparity. 
     
     
         35 . The system of  claim 34 , wherein the first portion and the second portion have at least one of a same angular size and a same shape. 
     
     
         36 . The system of  claim 29 , wherein the at least one property of the first and second portions comprises a size of each of the first and second portions, and wherein receiving the user input comprises receiving user input indicative of adjustment of the size of the first and second portions. 
     
     
         37 . The system of  claim 36 , wherein the adjustment of the size of the first and second portions comprises rescaling at least one of the first and second portions. 
     
     
         38 . The system of  claim 29 , wherein determining alignment of the right and left eyes of the user comprises determining at least one of an angle of deviation, scale deviation, and rotational deviation of the right and left eyes of the user. 
     
     
         39 . The system of  claim 29 , wherein the first and second portions comprise separate parts of an image of a scene. 
     
     
         40 . The system of  claim 29 , wherein the first and second portions comprise visually distinct parts of the object. 
     
     
         41 . The system of  claim 29 , wherein the user input is received from at least one input device selected from the group consisting of a mouse, a keyboard, a gesture and motion tracking device, a microphone, at least one camera, an omnidirectional treadmill, and a game pad. 
     
     
         42 . The system of  claim 29 , wherein the user input comprises eye tracking information acquired by at least one eye tracking sensor of the head-mountable virtual reality device, the at least one eye tracking sensor being configured to track the right and left eyes of the user wearing the head-mountable virtual reality device and viewing the virtual reality environment on the virtual reality display. 
     
     
         43 . The system of  claim 29 , wherein the operations performed by the computing hardware further comprise determining, based on the received user input, that the user is not able to use the right and left eyes simultaneously, and wherein adjusting the at least one property of the first and second portions comprises displaying the first and second portions such that the first and second portions are to be viewed by only one of the right and left eyes. 
     
     
         44 . The system of  claim 29 , wherein the head-mountable virtual reality device comprises glasses. 
     
     
         45 . The system of  claim 29 , wherein the user input is received using at least one sensor selected from the group consisting of a head tracking sensor, a face tracking sensor, a hand tracking sensor, a body tracking sensor, a voice recognition sensor, a heart rate sensor, a skin capacitance sensor, an electrocardiogram sensor, a brain activity sensor, a geolocation sensor, at least one retinal camera, a balance tracking sensor, a body temperature sensor, a blood pressure monitor, and a respiratory rate monitor. 
     
     
         46 . The system of  claim 29 , comprising a mobile computing device including the computing hardware. 
     
     
         47 . The system of  claim 29 , wherein the operations performed by the computing hardware further comprise providing a result relating to determining alignment of the right and left eyes of the user.
