摘　　要：讨论了手写笔电子白板系统中协同工作开发需要解决的并发控制、协同感知和协同记录与再现问题及解决途径,在系统实现中使用有人管理的悲观加锁并发控制、光标标识法协同感知和基于手写笔交互参数的协同记录再现及截图记录归档,较好地完善了手写笔电子白板系统中协同工作机制．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.
