Naturally, when we first laid our eyes on the LucidTouch prototype from Microsoft back in October, we were intrigued by the transparent multi-touch interface that allows users to control the device from behind the screen. Now, five months later, Microsoft has unveiled some artist mock-ups of what the device could look like as a final product. When compared to the prototype, it is readily apparent that they have a long way to go (especially with that bulky camera), but at least it is still an ongoing project. Whether users will prefer the UI to a traditional touchscreen remains to be seen. [LucidTouch via Pocket-Lint via DVICE]
