38. A method for building and utilizing tax preparation system related models using biometric data comprising: providing a tax preparation system; defining biometric data to be obtained and analyzed; providing one or more biometric data collection systems to obtain the defined biometric data; monitoring two or more users' interaction with the tax preparation system and obtaining user interaction activity data indicating the users' interaction with the tax preparation system at defined times; using the one or more biometric data collection systems to obtain biometric data associated with the users at defined times as the users interact with the tax preparation system; correlating the biometric data associated with the users with the users' interaction activity data at the defined times; obtaining baseline data associated with the users, the baseline data including data indicating when the baseline data was obtained; analyzing the biometric data associated with the users and correlated to the users' interaction activity data and the baseline data from the users, to generate emotional pattern predictive model data representing an emotional pattern predictive model associated with each of the users; analyzing the emotional pattern predictive model data representing the emotional pattern predictive models associated with each of the users to identify one or more user categories; identifying one or more user categories; for each user category identified, aggregating and analyzing the emotional pattern predictive model data associated with each of the users of that identified user category to generate user category emotional pattern profile data for that user category; determining that a current user of the tax preparation system is a user of one of the identified user categories and associating that user category with the current user; monitoring the current user's interaction with the tax preparation system and obtaining current user interaction activity data indicating the current user's interaction with the tax preparation system at defined times; using the one or more biometric data collection systems to obtain biometric data associated with the current user at defined times as the current user interacts with the tax preparation system; correlating the biometric data associated with the current user with the current user's location and/or activity within the tax preparation system; comparing the biometric data associated with the current user correlated to the current user's interaction activity data with the user category emotional pattern profile data for the user category associated with the current user; and if a deviation is found between the biometric data associated with the current user correlated to the current user's interaction activity data with the user category emotional pattern profile data for the user category associated with the current user, modifying one or more features and/or supporting systems associated with the tax preparation system to customize an tax preparation system user experience to the current user; and presenting the customized tax preparation system user experience to the current user.
