Baanto’s multi-touch ShadowSense technology to open up new possibilities for software developers and consumers


Baanto International (www.baanto.com), a Canadian developer of 2D and 3D position sensing technologies, has launched 19-inch ShadowSense E Series touchscreen assemblies, which the company says is poised to redefine the touchscreen landscape.

This new technology, according to the company’s Wednesday announcement, expands multi-touch capabilities for the kiosk, gaming, ATM, PC, PC monitor and additional markets by providing a robust and cost-effective touchscreen solution to support the development of innovative new applications.

“We believe ShadowSense is a better and more cost-effective touchscreen technology than any mid-size touch currently on the market. It is a high performance multi-touch solution competitively priced to single-touch technologies,” says Baanto chief technology officer and founder Av Utukuri. “This breakthrough technology supports up to four simultaneous touch inputs and provides multi-touch performance and gesture recognition in applications currently using ELO 1939L touchscreens. We expect this technology to replace single-touch SAW technology in the near future.”

The 19″ E Series touchscreens are available with two, three, or four touch points enabled. This is the first time that touch point size detection (Tsense) is available in a midsize touchscreen environment. Other firsts include the ability to recognize accidental touches, static object detection, and durability – significant improvements over existing touchscreen technology.

Utukuri says ShadowSense overcomes many of the shortcomings of other touch technologies such as ghosting, obscuration and “dead zones”, all common in imager or camera-based solutions. Using patented technology and position sensing algorithms, he says, ShadowSense that contribute to low cost, high performance sensor architectures that scale well, are easy to integrate, and do not require constant recalibration.

ShadowSense boasts a touch response time of less than six milliseconds and a touch detection of objects as small as two millimeters in diameter. As a perimeter-based technology, the ShadowSense touch sensor is independent of the protective glass, resulting in brighter displays, immunity to casual scratches and debris on the screen, and vandal resistant operation, while IP65 sealing resists dust and moisture intrusion.

Baanto CEO Joe Kotas notes that cell phones and touch pads have led to the dissemination and wide adoption of touch technologies. “These touch technologies, although used successfully for small displays, are often prohibitively expensive for displays larger than eight inches and require a bare finger touch,” he says. “ShadowSense technology scales exceptionally well to much larger displays, and it recognizes numerous touch mechanisms including, but not limited to, a pen, credit card, and gloved finger.”

By offering robust multi-touch functionality and a larger touchscreen at or below the cost of existing surface acoustic wave or SAW technology, ShadowSense is expected to appeal to the next generation developers and consumers to create and make use of the new applications made possible by this technology.
