Patent ID: 8010604

Claim:
A method of enabling conferencing using encoded forms, the method comprising: receiving, in a computer system, indicating data generated by a sensing device through interaction with first coded tags printed on a first conferencing encoded form, each first coded tag encodes data on an identity of the first conferencing encoded form associated with a form description in the computer system and the location of that first coded tag on the first conferencing encoded form, the indicating data is generated to include the data encoded by at least one of the first coded tags sensed by the sensing device when placed in operative position relative to the first conferencing encoded form; determining, in the computer system and from the indicating data and form description, conference information; and outputting, from the computer system, a second conferencing encoded form with second coded tags, the determined conference information and a hierarchical tree of form versions, the computer system producing the hierarchical tree of form versions by associating an identity of the second conferencing encoded form with said form description by determining each second coded tag encoding data on the second conferencing encoded form identity and the location of that second coded tag on the second conferencing encoded form.
