Multi-touch Monitors For Presentations
Interactive whiteboards have become popular for use in classrooms. However, these are expensive, limited to use by a small number of people. They have proved less popular in university teaching spaces. An interesting alternative is a touch sensitive LCD monitor, such as the HP 2310t, 23 Inch Monitor. This looks like an ordinary wide screen monitor, but has a multi-touch interface surface, like a large tablet computer. At about $550 this is less than an interactive whiteboard. It could be placed out the front of a tutorial room or lecture theatre, in place of a conventional monitor and used with a mouse and keyboard. When the touch interface was needed the screen could be tilted almost horizontal and used by one or two people, with the display relayed to a large projection screen for the class to see.
