If people realise they are being watched then their behaviour is different. There is potential for remote video cameras in suitable locations that allow people to be observed remotely. Building a remote lab Figure 18. A remote laboratory. The diagram shows a generic modular design for a remote laboratory.
Remote equipment is connected to a computer via some electronic interface.
Each piece of equipment has a driver which translates instructions from the simulator into commands that the equipment can understand, and translates the signals coming back from the equipment into meaningful results. A piece of software mediates between these drivers and the user interface. We have borrowed the terminology of the Multiverse project again to call this the mapping layer. It is possible for a remote laboratory to incorporate a model of the remote system, as discussed in the next section. The lab provides students with a virtual representation of actual mechanical systems that can be modelled.
