NTU debuts new touch-sensing technology
Singapore's Nanyang Technological University (NTU) has just unveiled a new touch-sensing technology. Called
STATINA or "speech touch and acoustic tangible interfaces for next-generation application", this technology is
designed to transform large surfaces into low-cost touchscreens. Statina is the brainchild of a team of
researchers lead by NTU assistant professor Andy Khong and has been in development for over four years.

Unlike conventional capacitive touchscreens with embedded electrical sensors, STATINA uses low-cost vibration
sensors and Webcams. It pinpoints a position by detecting vibrations, which are created when a user touches
the screen. Meanwhile, the Webcams add multi-touch and continuous tracking support. This unique approach
makes STATINA highly scalable and can be easily adapted for various screen sizes.

To date, STATINA has been successfully tested on a variety of surfaces, ranging from wood to metal and glass.
With a high tracking precision in the millimeter range, this technology is said to be just as accurate as most
capacitive touchscreens. More importantly, it costs roughly one tenth of the latter, according to Khong, though he
was quick to add that STATINA is most cost effective for 50-inch and larger screens.

STATINA is expected to be commercialized in the next 1.5 to 4 years and a retail version will be available for
consumers. Some of its commercial applications include both electronic white boards and interactive digital
signage. In homes, STATINA could be incorporated into furniture and electronic products, such as a TV. There're
non-display usages as well, including the idea of a target board that can detect bullet hits.
