Device and method for providing visual perceptual training

A method for providing visual perceptual training for improving cognitive ability, the visual perceptual training being performed by a visual perceptual training device, the method comprising:

• outputting an instruction message informing a trainee of a rule related to the visual perceptual training;
• providing a training session for the visual perceptual training;
• and
• storing a result in the training session for evaluating the cognitive ability of the trainee,
• wherein the providing of the training session includes:
• sequentially displaying a plurality of orientation indicators, which are a plurality of visual objects each moving in an individual orientation;
• checking a type of a response of the trainee;
• determining whether the checked response is correct according to the rule including a first condition and a second condition based on an attribute of a visual object of the plurality of visual objects, a display order of the visual object, and the type of the checked response;
• and
• outputting a feedback indicating that the checked response is correct,
• wherein the first condition is to provide an identification task to the trainee in the training session, and request, from the trainee, a first response when the visual object having a first attribute is displayed and a second response when the visual object having a second attribute is displayed,
• wherein the second condition is to provide a cognitive task together with the identification task such that the training session requests a cognitive load from the trainee, and when the order of the displayed visual objects is a predetermined number, request a third response from the trainee,
• wherein the second condition have a higher priority than the first condition, and
• wherein the providing of the training session further includes:
• adjusting a difficulty level of the visual perceptual training in the training session based on the trainee's response, by varying motion coherence, which is a ratio of consistently moving visual objects among the plurality of visual objects.
