Knobs have been put on the IEEE endangered list. They’re being replaced by cheaper, smaller components in most consumer electronics products. But Girton Labs’ SenseSurface prototype will let them make a comeback, as an accessory for your laptop screen. Apply a special backing to your laptop’s LCD, and place as many of these magnetic knobs and such wherever you want on the screen. Then pinch and twist as much as you want — real physical devices for real physical control and feedback. Ahh, it feels good to have a body again!
Such a system may allow visually impaired users to navigate audio recording interfaces will confidence and ease (although we all know the software should be fully navigable by keyboard).
