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.
Claims16
A method comprising:
- receiving input from a user as the user takes a test in which the user identifies novel images in a virtual reality environment executing on a computer, if any, and novel quadrant locations of images, if any, among a first ordered set of two or more image panels presented to the user in series relative to a second ordered set of image panels presented to the user in series, wherein an image panel comprises at least three different images, and wherein the input comprises an indication of no change or change between an image panel in the first ordered set and an image panel from a same order position in the second ordered set as an order position of the image panel in the first ordered set;
- measuring performance of the user in the test based at least in part upon the received input;
- and
- using the measured performance of the user on the test in analysis of cognitive status.

A method comprising:
- displaying to a user, in a virtual reality environment executing on a computer, a first ordered set of two or more image panels in series, wherein each image panel includes a plurality of images;
- after the series of the first ordered set of images is displayed, displaying a second ordered set of two or more image panels that correspond to the first set of image panels, wherein at least one of the second ordered set of image panels has one of the images associated therewith in a novel location on the image panel when compared to the first ordered set of images;
- receiving input from the user indicating the novel location;
- and
- measuring performance of the user based at least in part upon the received input to analyze cognitive status.
2 more elements
A system comprising:
- a virtual reality environment executing on a computer including a processor for displaying a first ordered set of two or more image panels in series, wherein each image panel includes a plurality of images and, after the series of the first ordered set of images is displayed, for displaying a second ordered set of two or more image panels that correspond to the first set of image panels, wherein at least one of the second ordered set of image panels has one of the images associated therewith in a novel location on the image panel when compared to the first ordered set of images;
- a user input device for receiving input from the user indicating the novel location;
- and
- the processor for measuring performance of the user based at least in part upon the received input to analyze cognitive status.
