Can you still call a touch screen a touch screen if you don't have to physically touch the panel to register a command? Apparently, yes. Cypress' new hover-detection feature for capacitive touch screens lets you do exactly that. In other words, you don't actually need to touch the display to zoom in on a Web page or enlarge certain points of interest on a map. As your finger moves closer to the screen, the corresponding onscreen bubble (magnifying glass of sort) grows bigger.
This whole proximity sensor concept looks eerily similar to what Apple patented recently. Then again, Apple patents almost everything, so we're not sure how this will pan out in the near future. On our end, it feels like a rather awkward interface. In hindsight, BlackBerry's clickable touch screen sounds like a better solution, for now anyway.
