Patent number: 11169604Abstract: A method for determining gaze calibration parameters for gaze estimation of a viewer using an eye-tracking system. The method comprises obtaining a set of data points including gaze tracking data of the viewer and position information of at least one target visual; selecting a first subset of the data points and determining gaze calibration parameters using said first subset. A score for the gaze calibration parameters is determined by using the gaze calibration parameters with a second subset of data points, wherein at least one data point of the subset is not included in the first subset. The score is indicative of the capability of the gaze calibration parameters to reflect position information of the at least one target visual based on the gaze tracking data. The score is compared to a candidate score and if it is higher, the calibration parameters are set to the candidate calibration parameters and the score to the candidate score.Type: GrantFiled: November 16, 2020Date of Patent: November 9, 2021Assignee: Tobii ABInventors: Patrik Barkman, David Molin

Publication number: 20200225745Abstract: A gaze tracking model is adapted to predict a gaze ray using an image of the eye. The model is trained using training data which comprises a first image of an eye, reference gaze data indicating a gaze point towards which the eye was gazing when the first image was captured, and images of an eye captured by first and second cameras at a point in time. The training comprises forming a distance between the gaze point and a gaze ray predicted by the model using the first image, forming a consistency measure based on a gaze ray predicted by the model using the image captured by the first camera and a gaze ray predicted by the model using the image captured by the second camera, forming an objective function based on at least the formed distance and the consistency measure, and training the model using the objective function.Type: ApplicationFiled: December 16, 2019Publication date: July 16, 2020Applicant: Tobii ABInventors: David Molin, Erik Lindén

Patent number: 9464994Abstract: Highly sensitive and tunable RF sensors that provide detection and analysis of single cells and particles are provided. The tunable RF sensors are configured as tunable interferometers, wherein cells or particles to be analyzed are passed through a channel, such as a microfluidic channel, across waveguides corresponding to reference and test branches of the interferometers. A network analyzer coupled to the interferometers can be configured to measure a plurality of scattering parameters, such as transmission scattering coefficients (S21) of the reference and test branches, to evaluate characteristics of cells passing through the channel. A plurality of tunable interferometers may be employed, each interferometer operating in different frequency bands such that information obtain from the plurality of interferometers may be combined to provide further information.Type: GrantFiled: July 29, 2014Date of Patent: October 11, 2016Assignee: Clemson UniversityInventors: Pingshan Wang, Yan Cui, Yuxi He, David Moline, Jiwei Sun

Publication number: 20050274470Abstract: The fluid intake rate of a tissue product having at least one hydrophobic exterior layer can be increased significantly by the addition of apertures through the hydrophobic exterior layer to the tissue product's hydrophilic interior layer. The apertures allow for fluid to be absorbed by the hydrophilic interior layer, while leaving the hydrophobic exterior layer dry to the touch. The size, number and spacing of the apertures can be controlled to manage the absorbent properties of the tissue product. In one embodiment, a three-ply tissue product has two exterior hydrophobic plies each having a plurality of apertures extending from the surface of both exterior plies through the plies to a hydrophilic interior ply.Type: ApplicationFiled: June 10, 2004Publication date: December 15, 2005Inventors: Thomas Shannon, David Moline, Tammy Balzar, Jeffrey Mathews, John Urlaub
