Predictive executive functioning models using interactive tangible-graphical interface devices
A method of diagnosing attention deficit hyperactivity disorder (ADHD). The method employs a tangible graphical interactive game wherein the interactive game employs a plurality of tangible graphical cubes. The game induces stimuli, measures responses and accumulates the responses using a predefined set of variables into a predefined set of metrics, wherein the variables are determined using an interactive machine learning feedback algorithm.
1. A method of diagnosing Attention Deficit Hyperactivity Disorder (ADHD), comprising:
providing a tangible-graphical interactive game with a patient, the tangible-graphical interactive game comprising providing at least four cubes, one being a mallet cube, and the others being object cubes on which the images of rabbit, birds, a groundskeeper or a gopher are selectively and electronically displayed, the game comprising a fixed period over which measurement data are recorded, the measurement data comprising the location of the object and mallet cubes, and further comprising the continuous location and orientation of the mallet cube; and wherein the object of the game is for a patient to strike the object cube displaying a gopher with the mallet cube, and if successful, sounding a bonk noise;
playing the game in at least three sessions comprising three levels of increasing spatial distraction, the three sessions comprising:
arranging the object cubes in a row having a first spacing and then playing the game in a first session and generating first measurement data;
generating from the first measurement data from the first session using a predefined set of variables, a set of first measured metrics;
arranging the object cubes in a diagonal having a first spacing and then playing the game in a second session and generating second measurement data;
generating from the second measurement data from the second session using a predefined set of variables, a set of second measured metrics;
arranging the object cubes in a diagonal having a second spacing greater than the first spacing and then playing the game in a third session and generating third measurement data;
generating from the third measurement data from the third session using a predefined set of variables, a set of third measured metrics;
generating from the first, second and third measured metrics a signal that indicates whether there is a likelihood that the patient has ADHD.
2. The method of claim 1 wherein the game employs a plurality of tangible-graphical interactive cubes having electronic displays.
3. The method of claim 1 wherein the variables are determined iteratively employing a machine learning feedback algorithm.
4. The method of claim 1 wherein the generating steps comprise employing a Random Forest algorithm.
5. The method of claim 1 wherein the predetermined stimuli further comprises various levels of distraction within each of said visual, audio and spatial distractions.
