The Teaching Station is the standard UofT electronic podium
for classrooms over 100 persons. You use it to project your presentation from the ceiling-mounted digital projector, or to amplify your voice through the installed room speakers. The TS is fixed to the floor 5' out from the wall and has a touch-screen and computer.
The TSJr is a smaller platform for medium-sized rooms,
40-100 persons. It is fixed against the wall and has no computer - you hook up your own laptop. It feeds your laptop signal to a ceiling-mounted data projector, with sound and video.
