Abstract

An electronic meeting is attended by participants with touch-sensitive display devices. An electronic meeting server allows a group of selected participants to edit a shared document during the meeting. Another group of participants may cast votes during the meeting using objects at least partially created during the meeting. Each participant has an active stylus for interfacing with a touch-sensitive display device during the meeting. The active stylus has a stylus identification signal associated with each participant. The stylus identification signal allows for selection and management of the editing and voting groups and allows multiple participants to share a touch-sensitive display device.
