Chinese hardware vendor Lenovo has dreamt up a smartphone concept that may create the kind of industry disruption that pundits have been baying for: a mobile handset equipped with a projector that can turn any surface into a touch screen.

Lenovo unveiled the idea at its Tech World conference in Beijing. The Smart Cast phone, which will be equipped with a focus-free laser projector, is nowhere near being market-ready, but the technology is not new. The only question that remains is how the company plans to miniaturise existing tech to place it in a 5- or 6-inch smartphone.

Lenovo released a promotional video of the proposed projector phone. The 1m 20s film showed a teardown and some footage of the device in action, projecting home movies on living-room walls and turning bare table tops into keyboards. Being focus-free allows the laser projector to render sharp images at any angle.

At the time of writing there are no details on how far Lenovo is from bringing the concept to market. It is also unclear how the company proposes to get the touchscreen aspect to work. The human hands featured in the promotional video are not adorned with any gloves, rings bracelets or other items that could serve as peripheral hardware.
