First Claim
Patent Images
1. A method comprising:
- receiving input from a user as the user interacts with software presenting a virtual reality environment that includes a first-person, three-dimensional graphical rendering of the virtual reality environment;
measuring performance of the user in the virtual reality environment based at least in part upon the received input; and
using the measured performance of the user in the virtual reality environment in analysis of cognitive status;
wherein the measured performance includes one or more of distance traversed in the virtual reality environment, time elapsed before reaching a target in the virtual reality environment, percentage of successful trials, time spent in a target area of the virtual reality environment, and velocity of movement in the virtual reality environment.

Abstract
Techniques and tools for measuring cognitive ability and/or detecting cognitive impairment or decline. For example, techniques and tools are described that can be used to diagnose or test susceptibility to cognitive impairments in children or in elderly people (such as cognitive impairments associated with Alzheimer'"'"'s Disease). Techniques and tools are described that can be used to evaluate treatment effects and/or measure cognitive decline over time.

34. A method comprising:
-
receiving input from a user as the user interacts with software presenting a virtual reality environment that includes a first-person, three-dimensional graphical rendering of the virtual reality environment; in a first round, measuring performance of the user in navigating in the virtual reality environment to a target indicated by at least a first visual cue in the virtual reality environment based at least in part upon the received input; in a second round that lacks the at least first visual cue, measuring performance of the user in navigating to the target in the virtual reality environment based at least in part upon the received input; using the measured performance of the user in the virtual reality environment for the first and second rounds in analysis of cognitive status.

35. A method comprising of correlating genotype with cognitive status, the method comprising:
-
receiving input from a user known to have a first genotype as the user interacts with software presenting a virtual reality environment that includes a first-person, three-dimensional graphical rendering of the virtual reality environment; measuring performance of the user in navigating to a target in the virtual reality environment based at least in part upon the received input; using the measured performance in analysis of cognitive status for the user known to have the first genotype, wherein the analysis comprises a comparison of the measured performance of the user in the virtual reality environment relative to measured performances for a user group for the first genotype. - View Dependent Claims (36)
