Keijyu Tokutani has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9538947
    Abstract: Method, system and device for assisting diagnosis of autism which enable assistance of early detection and early definite diagnosis of autism (especially in infants) based on objective evaluation, using a conventionally suggested “eye-gaze detection technique”. The method for assisting diagnosis of autism of a subject uses an eye-gaze detecting unit, the unit having at least an imaging camera portion. The method includes displaying, at the position in front of the subject along the direction of the eye gaze of the subject, an illusionary image contained in a plane of an illusion-causing image on a displaying device. The eye-gaze position information of the subject looking at the plane is detected, and the eye-gaze position information of the subject is input into an eye-gaze position information storage portion The eye-gaze positions of the subject can be evaluated using a algorithm for assisting diagnosis of autism.

  • Publication number: 20150050628
    Abstract: An autism diagnosis support method and system, and device capable of providing support to early detection and early definite diagnosis on the basis of objective evaluation, are provided by using a conventionally proposed “eye-gaze detection technique”. The method includes: displaying, on a screen of the display portion, a combination image for sequentially displaying at least two images including a predetermined human image (I) and a predetermined non-human image (II); and evaluating an eye-gaze position of the subject by detecting eye-gaze position information on the subject looking at the combination image in use of the eye-gaze detecting unit, then inputting the eye-gaze position information on the subject in an eye-gaze position information storing portion, and comparing, based on an eye-gaze position evaluation algorithm, the eye-gaze position information on the subject with eye-gaze position information on an individual with autism and/or a typically developing individual.
