Telepresence teaching is a very useful mean of allowing university teaching whenever there is a lack of local resources. To be effective it requires a user friendly environment for both teachers and learners. The experience of the technical University of Milan in delivering telepresence courses has promoted investigation and development of effective teleteaching equipment. A layered equipment architecture has been introduced while users requirements and available technologies are intertwined to identify equipment functional specifications. Modular equipment as a Teacher Tracker, a Laser Beam Mouse, a Student Pointer and a Multiplexed Videocodec are among the designed and prototyped equipment. The activity indicates the possibility of applying well established technologies in teleteaching systems by promoting University laboratories where user requirements and a large spectrum of technologies are investigated to anticipate useful products whenever markets specifications are not yet established.
