- Input Technologies and Techniques

The barometer has fallen and a brisk wind blows. Input and interaction are not what they used to be. Gusts drift over the line in the sand that separates input from output. The academic division between input and output as topics of study was never a principled one to begin with. But this is perhaps clearer now than ever before: Many people now primarily experience computing by direct-touch input on their displays. The shifting sands are rapidly unearthing a future where any surface on which we can display information will also serve as a surface that sees, hears, feels, and otherwise senses all our interactions. As some would have it, the encroaching dunes have all but buried the mouse, keyboard, and other indirect-input devices as archeological curiosities to be unearthed by a future generation of researchers, explorers, and scoundrels.
