Patent ID: 7765260

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