There are numerous complex tasks that can not be solved by a single human but can be easily solved if multiple humans interact. This concept can also be applied to telepresence systems. In such a multi-user-telepresence system several operators control several teleoperators and perform a collaborative task.

Such a system poses new difficulties for controller design and performance evaluation. One question that is being investigated is what control structure to use in order to achieve high performance interaction and maintain stability. Also, suitable performance criteria are being investigated.
