METHOD AND SYSTEM FOR SELECTING ITEMS USING PHYSIOLOGICAL PARAMETERS
First Claim
1. A method for selecting items, the method comprising the steps of:
- measuring (21) a pre-stimulus level of a physiological parameter of a user,selecting (22) an item based on a user profile and the pre-stimulus level of the physiological parameter,measuring (23) a post-stimulus level of the physiological parameter,determining (24) a stimulus effect by calculating a difference between the post-stimulus level and the pre-stimulus level,correcting (25) the stimulus effect using a model of an effect of the pre-stimulus level on the physiological parameter, andupdating (26) the user profile, using the corrected stimulus effect.

Abstract
A method for selecting items, the method comprising the steps of measuring (21) a pre-stimulus level of a physiological parameter of a user, selecting (22) an item based on a user profile and the pre-stimulus level of the physiological parameter, measuring (23) a post-stimulus level of the physiological parameter, determining (24) a stimulus effect by calculating a difference between the post-stimulus level and the pre-stimulus level, correcting (25) the stimulus effect using a model of an effect of the pre-stimulus level on the physiological parameter and updating (26) the user profile, using the corrected stimulus effect. The method may, e.g., be used for selecting media items in a music player or digital TV.

7. A system (10) for selecting items, the system (10) comprising:
-
means (11) for measuring a level of a physiological parameter of a user, a storage means (12) for storing a user profile, a processor (13) being operative to; measure a pre-stimulus level of the physiological parameter, select an item based on the user profile and the pre-stimulus level of the physiological parameter, measure a post-stimulus level of the physiological parameter, determine a stimulus effect by calculating a difference between the post-stimulus level and the pre-stimulus level, correct the stimulus effect using a model of an effect of the pre-stimulus level on the physiological parameter, and to update the user profile, using the corrected stimulus effect.
