METHOD FOR USING PSYCHOLOGICAL STATES TO INDEX DATABASES
First Claim
1. A method for creating an electronic database of objects that can be converted to sensory stimuli and associated responses, wherein the steps include:
- initializing an electronic database to contain a set of objects to be used as stimuli;
connecting at least one of a set of measurement devices to a user;
selecting at least one object of said set of objects from said electronic database to present to said user;
presenting said at least one object of said set of objects to said user;
measuring physiological response attributes of said user to said at least one object of said set of objects;
associating said physiological response attributes of said user with said at least one object of said set of objects that invoked said physiological response attributes; and
updating said electronic database with associations of each of said at least one of said set of objects with said physiological response attributes.

Abstract
The present invention provides a method for capturing and storing physiological response attributes measured from a user while different stimuli are presented. Each stimulus may be any multimedia object, for example text, picture, or audio/video. The measured physiological response attributes are paired with the input stimulus, and stored conjointly in one or more databases. The physiological response attributes measure an aspect of the user known as emotional valence, and relate to the emotional state of the user, such as angry or sad. The database of physiological responses attributes of multiple users is first established. Then, when the physiological response attributes of a specific user in the future is examined, the system can suggest which objects in the database best correspond. Moreover, the database can be constructed based on the responses of the individual user for their own utilization, and be updated over the course of its continued use.

6. A method for using objects and associated physiological response attributes stored in a database includes the steps of:
-
connecting at least one of a set of measurement devices to a user; measuring physiological response attributes of user; computing a distance between said measured physiological response attributes and stored physiological response attributes in said database; presenting said at least one object of said set of objects to said user that correspond to said measured physiological response attributes, wherein said at least one of said set of objects is presented based on a matching threshold of said distance; and selecting from said set of object at least one object of said set of objects for use by said user. - View Dependent Claims (7, 8)
