Low Cost Portable Touch Screen Technology Applied to University Teaching

This article describes an implementation of low-cost portable touch screen technology, applied to university teaching, using as a base the remote control of the Nintendo Wii console (known as Wiimote), a normal projector, a computer and free software. The purpose is to show the feasibility of such implementation to improve teaching/learning processes, without incurring high costs associated with unaffordable technological equipment, special infrastructure in classrooms, or expensive computer programs. Also included is a summary of a test of the system in two college courses.
