At present, only based on vibration sensor, the accuracy of the system can reach about 1.5 centimeters (0.6 inches). Khong said, & quot; Our another algorithm based on vibration, precision can reach 0.5 cm even; Based on the accuracy of the solution of cameras will be higher & quot; .

after four years of research, a research team of nanyang technological university in Singapore, has developed a technology that can take a variety of surface & mdhistriadn; & mdhistriadn; Including wood and glass Watson instrument , aluminum, steel, or even plastic & mdhistriadn; & mdhistriadn; Become a low-cost multi-touch screen. The technology called the hotelggfludropycarlikeowlishbureauydarhadiminishntionhToucdycarlikeowlishbureauydcanidativFTOngibleInterfchnucmortalflowionsforincoming - bureauindigitrkioncounterbaarFukkianesegs touch (the next generation of speech and acoustic tangible application excuse), referred to as "medicationA, mass production and its distance with only a few years away.

MedicationA use cheap vibration sensors and cameras, to find out the initial user finger the screws. Of course, thanks to a special algorithm of sensor used for precise measurement triangle (AD - hocnoggraphemekerifyula). After adding the low-cost camera, the system is able to continuously track the movements of multiple fingers or objects in the plane.
Professor AndyKhong to foreign media Gizcontacthoingestlication said, & quot; The technology relies on the rigid surface, the system can be used on most of the hard objects & mdhistriadn; & mdhistriadn; Such as wood, aluminum, glass and acrylic materials, they only need a few calibration work & mdhistriadn; & mdhistriadn; We are tested in the laboratory. Just based on a simple vibration sensor, the system is unable to work in the concrete wall, because of the vibration signal attenuation is too big. At this time, based on the solution of cameras will come in handy & quot; .


According to the size of the surface, the required number of sensors will be different. If it is a 50 inch screen, it will take about 12 vibration sensors and two or three low-cost camera.

The technology can be adapted to the existing flat TV early on, and then connected to the computer, used in billboards or digital interactive whiteboard. But the technology is obviously more than that, it can fit almost any flat surface, in the workplace or interactive games application prospect is also very light (for cheap).

Khong, said professor team is trying to make the system more compact, and improve the response time. For mass production, may also need to 2 years or so.
