BIMANUAL COMPUTER GAMES SYSTEM FOR DEMENTIA SCREENING
First Claim
1. A system of screening a patient for cognitive impairment comprising:
- a computer;
a videogame executing on the computer;
a display portraying action from the videogame, the action being viewable by the patient;
a game controller connected to the computer having one or more hand-held components with a button or trigger, wherein the hand-held components can be moved independently from one another;
the game controller adapted to send to the computer one or more signals representative of a position of the hand-held component and a position of the button or trigger on the hand held component;
the game controller adapted to send the one or more signals as the patient changes the position of the hand-held component and the position of the button or trigger on the hand-held component in response to action from the videogame;
the computer adapted to quantify a measure of cognitive impairment based on the one or more signals received by the controller and by compounding performance in one or more games.

Abstract
The majority of cognitive virtual reality (VR) applications have been for therapy, and not cognitive screening/scoring. Provided herein is the BrightScreener™ and its first pilot feasibility study for evaluating elderly with various degrees of cognitive impairment. BrightScreener is a portable (laptop-based) serious-gaming system which incorporates a bimanual game interface for more ecological 3D interaction with virtual worlds. A pilot study determined that BrightScreener is able to differentiate levels of cognitive impairment based solely on game performance, as well as to evaluate the technology acceptance by the target population. Subsequent group analysis of the Pearson correlation coefficient showed a high degree of correlation between the subjects'"'"' MMSE scores and their Composite Game Scores (0.90, |P|<0.01). Despite the small sample size (n=11), results suggest that serious-gaming strategies can be used as a digital technique to stratify levels of Cognitive Impairment. This may be an alternative to conventional standardized scoring for Mild Cognitive Impairment and Dementia, especially for patients with hearing and speech deficits.

10. A method of screening a patient for cognitive impairment comprising the steps of:
-
executing a video game on a computer and portraying action from the videogame on a display, the action on the display being viewable by the patient; the patient holding a game controller comprising one or more hand-held components having a button or trigger, wherein the hand-held components can be moved independently; the patient performing an action in the video game by moving the relative position of the hand-held component and manipulating the button or trigger on the hand-held component; the computer receiving a signal from the controller representative of the position of the hand-held component and the manipulation of the button or trigger; the computer calculating a degree of cognitive impairment by quantifying the movement of the hand-held component and quantifying manipulation of the button or trigger on the hand-held component as they map to avatars in the games. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
