| Abstract: | Some basic issues and approaches of collaborative work were discussed in developing electronic whiteboard with tablet, such as concurrency control, collaborative awareness and recording and redisplaying of collaborative information. Then efficiency methods, which are pessimistic lock managed by man for concurrency control, cursor indicator for collaborative awareness , redisplaying of collaborative information based on tablet's operation parameter and archieved cut images, are applied to the implementation of system and improved collaborative working feature. |
