The issue of multiuser interaction with a single device is addressed in a typical situation of educational entertainment: the visit to a museum. To allow for these multiuser interactions, the museum is equipped with stationary systems, so called Virtual Windows, which are distributed throughout the museum. While each visitor may rent a mobile information system, based on a personal digital assistant, the number of stationary systems is significantly lower than the number of visitors in the museum. Hence, to maximize the benefit of the visitors, it is necessary to allow several users to interact with a Virtual Window at the same time. Since these multiuser interactions are uncommon to most users, a virtual character is used to support the users in their interactions.
