METHOD AND SYSTEM FOR QUANTITATIVE ASSESSMENT OF FACIAL EMOTION NULLING
A method is presented to address quantitative assessment of facial emotion nulling of a subject, where the method comprises the steps of: ( 1 ) presenting at least one scene, comprising a single facial expressions and a background, to a subject on a display; ( 2 ) adjusting the facial expression on the scene; ( 3 ) receiving feedback from the subject via at least one input device; ( 4 ) quantitatively refining the received feedback; ( 5 ) modulating the adjusted facial expression relative to the accuracy of the quantitatively refined feedback; ( 6 ) transforming the modulated facial expression; ( 7 ) calculating a critical threshold parameter; and ( 8 ) recording a critical threshold parameter onto a tangible computer readable medium. An apparatus for quantitative assessment of facial emotion nulling of a subject comprising a display device, an input device, a control device, and a tangible computer readable medium. In its simplest sense, a quantitative assessment profile of facial emotion nulling by psychophysical responses is generated on a tangible computer readable medium.
1 . A method for assessment of facial emotion nulling of a subject, said method comprising the steps of:
presenting at least one scene to said subject on a display, said scene comprising a single facial expression and a background;
adjusting said facial expression on said scene;
receiving feedback from said subject via at least one input device;
quantitatively refining said received feedback relative to said scene;
modulating said adjusted facial expression relative to accuracy of said quantitatively refined feedback, said modulated facial expression associated with a predetermined target;
transforming said modulated facial expression;
calculating a critical threshold parameter for said subject; and
recording said critical threshold parameter onto a tangible computer readable medium.
2 . The method of claim 1 , further comprising at least one of the additional steps of:
monitoring at least one response error from said subject; and
measuring said response error relative to a predetermined threshold;
3 . The method of claim 1 , wherein said facial expression further comprises a human facial expression.
4 . The method of claim 1 , wherein said facial expression is associated with happiness.
5 . The method of claim 1 , wherein said facial expression is associated with sadness.
6 . The method of claim 1 , wherein said adjusted facial expression is associated with happiness.
7 . The method of claim 1 , wherein said adjusted facial expression is associated with sadness.
8 . The method of claim 1 , wherein said step of adjusting further comprises altering said facial expression from happiness to sadness.
9 . The method of claim 1 , wherein said step of adjusting further comprises altering said facial expression from sadness to happiness.
10 . The method of claim 1 , wherein said critical threshold parameter is implemented in a different functional impairment assessment test.
11 . The method of claim 1 , wherein said modulated facial expression further comprises a change in at least one of the following:
facial gender;
age;
the degree of happiness; and
the degree of sadness.
12 . The method of claim 1 , wherein said transformed facial expression further comprises a change in at least one of the following:
facial gender;
age;
the degree of happiness; and
the degree of sadness.
13 . The method of claim 11 , wherein said transformed facial expression is associated with at least one response error.
14 . The method of claim 12 , wherein said transformed facial expression is associated with at least one response error.
15 . An apparatus for quantitative assessment of facial emotion nulling of a subject comprising:
a display for presenting a scene comprising a facial expression and a background;
an input device for tracking movement from said subject;
a control device, said control device capable of performing the following steps:
adjusting said facial expression on said scene;
receiving feedback from said subject via at least one input device;
quantitatively refining said received feedback relative to said scene;
modulating said adjusted facial expression relative to accuracy of said quantitatively refined feedback, said modulated facial expression associated with a predetermined target;
transforming said modulated facial expression; and
calculating a critical threshold parameter for said subject.
a tangible computer readable medium for recording said critical threshold parameter.
16 . The apparatus of claim 15 , wherein said display presents at least one temporal variation in said scene.
17 . The apparatus of claim 15 , wherein said display presents at least one spatial variation in said scene.
18 . The apparatus of claim 15 , wherein said control device monitors at least one response error from said subject.
19 . The apparatus of claim 15 , wherein said control device measures the response error relative to a predetermined threshold.
20 . A tangible computer readable medium, said tangible computer readable medium containing instructions comprising the steps of:
presenting at least one scene to said subject on a display, said scene comprising a single facial expression and a background;
adjusting said facial expression on said scene;
receiving feedback from said subject via at least one input device;
quantitatively refining said received feedback relative to said scene;
modulating said adjusted facial expression relative to accuracy of said quantitatively refined feedback, said modulated facial expression associated with a predetermined target;
transforming said modulated facial expression; and
calculating a critical threshold parameter for said subject.
