Method and apparatus for using physical characteristic data collected from two or more subjects

A method for providing feedback, comprising:

• receiving data indicative of a physical characteristic of each of a plurality of subjects, wherein said physical characteristics of said subjects are indicative of responses of said subjects to a presentation;
• determining a desired course of action associated with said plurality of subjects based, at least in part, on said data indicative of a physical characteristic of each of said plurality of subjects;
• and
• providing a notification based, at least in part, on said course of action.

A method for providing feedback, comprising:

• determining a desired action associated with a group of subjects;
• receiving data indicative of a physical characteristic of at least one of said group of subjects, wherein said physical characteristic of said at least one of said group of subjects is indicative of a response of said at least one of said group of subjects to a presentation;
• determining a course of action expected to lead to said desired action based, at least in part, on said physical characteristic and said desired action;
• and
• providing a notification based on said course of action.

A system for facilitating feedback, comprising:

• a memory;
• a communication port;
• and
• a processor connected to said memory and said communication port, said processor being operative to:
• receive first data indicative of a physical characteristic of a first subject and second data indicative of a physical characteristic of a second subject;
• determine an evaluation of said first data and said second data, wherein said evaluation is representative of a state associated with both said first subject and said second subject;
• and
• provide a notification regarding said evaluation to device.

A computer program product in a computer readable medium for using feedback, comprising:

• first instructions for obtaining receiving first data representative of a physical characteristic of a first subject and second data representative of a physical characteristic of a second subject;
• second instructions for preparing an evaluation of said first data and said second data, wherein said evaluation is representative of a state associated with both said first subject and said second subject;
• and
• third instructions for sending third data indicative of said evaluation of said first data and said second data to a device.

A method for providing feedback, comprising:

• receiving first data indicative of a physical characteristic of a first subject from a first device associated with said first subject and second data indicative of a physical characteristic of a second subject from a second device associated with said second subject;
• determining an evaluation of said first data and said second data, wherein said determining said evaluation includes comparing said physical characteristic of said first subject to at least one record of behavior associated with said physical characteristic of said first subject;
• and
• providing a notification regarding said evaluation to a device.
