System for testing and/or training the vision of a user

A system for testing and/or training the vision of a user, said system comprising:

• at least one camera, the at least one camera configured to capture a plurality of images of a head of a user during a vision test or vision training routine;
• a visual display device having an output screen, the visual display device configured to display one or more visual objects on the output screen so that the one or more visual objects are visible to the user;
• and
• a data processing device, the data processing device operatively coupled to the at least one camera and the visual display device, the data processing device being programmed to:
• generate and display one or more configurations of a visual object on the output screen of the visual display device during the vision test or vision training routine;
• determine a head velocity or head speed of the user during the vision test or vision training routine from the plurality of images of the head of the user captured by the at least one camera;
• and
• determine whether or not the user correctly identifies the one or more configurations of the visual object displayed on the output screen of the visual display device;
• wherein the data processing device is further programmed to determine the head velocity or the head speed of the user from the plurality of images of the head of the user captured by the at least one camera by performing the following additional steps:
• extracting features from the plurality of images of the head of the user for providing inputs to a trained neural network;
• determining one or more head poses and/or head movements of the user using the output of the trained neural network;
• and
• determining the head velocity or the head speed of the user from the one or more head poses and/or head movements of the user.
