Patent number: 11869386Abstract: Techniques for generating and administering an oculo-cognitive addition test. Some aspects include identifying, by a system, a set of numbers that are to be displayed to a user during a trial of a cognitive test. The set of numbers includes at least two numbers. The system can administer the trial of the cognitive test, including, for each number in the set of numbers: displaying the number at a particular position of a display environment; tracking, by the system and using one or more optical sensors, eye movement of the user seeking the number in the display environment; and receiving, by the system and after having displayed the number for a time, a command that is to advance or end the cognitive test.Type: GrantFiled: October 30, 2017Date of Patent: January 9, 2024Assignee: Mayo Foundation for Medical Education and ResearchInventors: Gaurav N. Pradhan, Michael J. Cevette, Jan Stepanek, Kenneth H. Brookler

Patent number: 10628979Abstract: A method for operating a computer system to generate and display multidimensional data. A set of multidimensional data points and a selected deviation range is received at a processor. The processor processes each data point to determine its value about the selected deviation range. Display data representative of data point indicia of the determined data point values at circumferentially spaced locations and with respect to an origin in a coordinate system is generated and stored by the processor. The data point indicia for the multidimensional data points are at circumferentially spaced locations, and a radial distance of the indicia with respect to the origin represents the determined data point values. A visual display of the display data can be produced on a printer or monitor.Type: GrantFiled: November 4, 2015Date of Patent: April 21, 2020Assignee: Mayo Foundation for Medical Education and ResearchInventors: Jan Stepanek, Gaurav N.
