1. A method for multi-user recognition for a multi-touch display joined to a processor comprising the steps of:
- providing a multi-touch display joined to a processor;
providing a processor having a database with stored user data therein, the stored user data for each user comprising user hand metrics and other user data;
identifying a hand press on the multi-touch display;
generating hand metrics from the identified hand press wherein the generated hand metrics comprise multi-touch display location, hand orientation, hand configuration, and hand dimensions;
comparing generated hand dimensions with user hand metrics in the database to determine if the hand metrics match those in the database;
requesting further user identification if the hand metrics fail to match those in the database;
identifying the hand press as a hand press from a recognized user if the hand metrics match the hand metrics for the user in the database with a specified tolerance;
retrieving other user data from the database based on the recognized user;
identifying an additional hand press on the multi-touch display;
generating additional hand metrics from the identified additional hand press wherein additional hand metrics include additional multi-touch display location, additional hand orientation, additional hand configuration, and additional hand dimensions;
determining if the additional hand metrics indicate an additional user or an additional hand of the recognized user;
associating the additional hand press with the recognized user if the additional hand metrics indicate an additional hand of the recognized user;
comparing generated hand dimensions if the additional hand metrics indicate an additional user to determine if the additional hand metrics match those in the database;
requesting further user identification if the additional hand metrics fail to match those in the database;
identifying the additional hand press as a hand press from a recognized additional user if the additional hand metrics match the hand metrics in the database with a specified tolerance;
determining an additional user data record in the database based on the recognized additional user; and
retrieving other user data from the database based on the recognized additional user.

Abstract
A method for multi-user recognition for a multi-touch display is provided. The method identifies a user by using metrics from a hand touch on the display. A hand based menu system is provided on the display in response. Menu system can be oriented in accordance with the hand touch. Stored user preferences can be retrieved for the identified user. The display can recognize an additional hand from the same user or an additional user'"'"'s hand. These can be used to provide a collaborative display. Optionally additional metrics can be utilized for user identification.
