Patent number: 11139066Abstract: The present disclosure relates to methods and tools for enhancing cognition in an individual. The methods involve presenting to the individual multiple sets of stimuli. Each set of the multiple set contains two or more stimuli and at least one set of the multiple sets contains a target stimulus. The method then receives an input from the individual, and informs the individual as to whether the input is a correct response. The methods encompass iterations of stimuli presentation, receiving of the input, and lastly, generation of feedback to the individual until the individual learns and retains what the target stimulus is.Type: GrantFiled: May 29, 2020Date of Patent: October 5, 2021Assignee: The Regents of the University of CaliforniaInventors: Etienne de Villers-Sidani, Xiaoming Zhou, Jyoti Mishra-Ramanathan, Michael Merzenich, Adam Gazzaley

Patent number: 11074714Abstract: A method for training a neural network for determining a gaze position of at least one eye in an initial image comprising the at least one eye. A plurality of training initial images are obtained, of which at least one training color component image is extracted, each of the training initial images respectively comprising at least one eye and a known gaze position. Those are fed into a neural network outputting a respective internal representation for each one of the at least one component image. The neural network is trained by readjusting weights in the neural network to have the respective internal representation for each one of the at least one training color component image more consistent with a respective one of the known gaze position. Once trained, the neural network is used to determine the estimated gaze position relative to a screen of an electronic device.Type: GrantFiled: June 5, 2020Date of Patent: July 27, 2021Assignee: INNODEM NEUROSCIENCESInventors: Etienne De Villers-Sidani, Paul Alexandre Drouin-Picaro

Patent number: 10713814Abstract: A computer-implemented method for determining a gaze position of a user, comprising: receiving an initial image of at least one eye of the user; extracting at least one color component of the initial image to obtain a corresponding at least one component image; for each component image, determining a respective internal representation; determining an estimated gaze position in the initial image by applying a respective primary stream to obtain a respective internal representation for each of the at least one component image; and outputting the estimated gaze position. The processing of the component images is performed using a neural network configured to, at run time and after the neural network has been trained, process the component images using one or more neural network layers to generate the estimated gaze position. A system for determining a gaze position of a user is also provided.Type: GrantFiled: June 7, 2019Date of Patent: July 14, 2020Assignee: INNODEM NEUROSCIENCESInventors: Etienne De Villers-Sidani, Paul Alexandre Drouin-Picaro
