Asustek's chairman on Sunday unveiled the company's plans to develop a wearable device that can be controlled using voice commands or customizable hand movements. Jonney Shih said Sunday that Asustek's first wearable device - most probably a smartwatch - will be used to complement a smartphone rather than be launched as a standalone device, Focus Taiwan reported on Sunday.

The company is considering new options for the user interface on the wearable device.

"There would be more natural user interfaces such as voice or movement controls, although more breakthroughs are needed in these areas," Shih said when answering students' questions at a job fair organized by National Taiwan University.

Another key issue to be addressed is power consumption, which should be lowered to about a tenth of that of a smartphone, Shih added.
