Method for user based application grouping under multi-user environment and table top display apparatus for performing the same

A table-top display apparatus performing a method for user-based application grouping in a table-top multi-user environment where a plurality of users execute applications individually, comprising:

• a geometric information collecting unit collecting geometric information of each window of a plurality of applications displayed on a table-top display, each window of the plurality of applications having different geometric information according to the position at which each user uses the table-top display;
• and
• a clustering algorithm processing unit using the collected geometric information as a criterion for classifying the plurality of applications and classifying geometric information of each window of the plurality of applications for each user by applying a clustering algorithm.

A method for user-based application grouping in a multi-user environment, comprising:

• collecting geometric information of each of a plurality of displayed applications, each of the plurality of applications having different geometric information for each user;
• and
• using collected geometric information of each of the plurality of applications as a criterion for classifying the plurality of applications and classifying the plurality of applications for each user by using a clustering algorithm.

A method for user-based object grouping in an augmented reality multi-user environment, comprising:

• collecting geometric information of each of a plurality of displayed objects, each of the plurality of objects having different geometric information for each user;
• and
• using collected geometric information of each of the plurality of collected objects as a criterion for classifying the plurality of objects and classifying the plurality of objects for each user by using a clustering algorithm.
