The Multitaction-technology behind OC Multiuser Multitouch
The human-user-interface continously improves with the multitouch-technology. Fingers and hands have become the expected navigational-tools of handheld devices, but for larger surfaces from 30-100 inches, this technology is quite new.
One Communication is proud to present the software and content-integrational optimized OC Multiuser Multitouch with 55 inch surface - it is in a league of its own.
Size matters, but the large mutltitouch installations also add some challenges in comparison to handheld devices.
The large installations allow multiple simultaneous users, so that effective collaborative applications can be developed. To meet these needs, Multitouch Ltd. developed MULTITACTION ®-technology and a platform for building large multi-user multitouch LCD screens in all sizes.
MULTITACTION literally takes a new angle on the multitouch. Multitouch Ltd's patented Computer Vision Through Screen (CVTS) optical image processing technology allows, not only tracking of an unlimited number of touch points, but also discover all the hands as well as objects and markers placed on the screen for sophisticated augmented reality applications. MULTITACTION uses multiple infrared cameras positioned behind the LCD screen, and with the new Matrix Tracking System (MTS), increases the number of cameras to anywhere between 4 and 100. The development of Integrated Backlight Emitter Camera (IBEC) modules, allows for thin displays, allowing us to just increase the amount of camera modules according to screen size increase.
MULTITACTION contains several other innovations, including Extensible Hybrid Tracking Engine (EHTE)-software that is built into the display. Hybrid Tracking aims to reduce the biggest pitfall for optical multitouch technologies: their susceptibility to external light sources. By alternating trace of reflection and shadows, this issue is corrected continuously.
To conclude, MULTITACTION supports all common standards to provide multitouch tracking data to applications that requesting it through the Multi-Format Tracking Output (MFTO) over ethernet.
