Scientists to improve the tactile feedback in an interactive holographic – Inter
How can so picture circling in the sky? How can I avoid these images have not appeared within a short time disappear? Recently, scientists at the University of Tokyo team to achieve a breakthrough on this issue, their interactive holographic Technology The tactile feedback technology to do an effective improvement of the names of these scientists were TakayukiHoshi, MasafumiTakahashi, KeiNakatsuma and HiroyukiShinoda.
Mentioned above, this technology also known as "touch holography," which is the team of Tokyo University of Science and technology providers Provision Interactive California Cooperation Part of product development technology. In order to achieve 3D holographic images, Japanese scientists team applied the Provision of holographic display products, "Holo", which is a mirror reflection rendering flat panel display using image technology. Prior to this, projection screen can be suspended in the display interface than 30cm Office, users can also be wireless access to these images, and can try to touch the screen with your fingers. Of course, these virtual finger touch screen, of course there is no sensory experience.
For the holographic display technology, scientists have once again developed the "airborne Overclocking touch display technology." This ensures the user remote display access to these virtual screen, tactile feel, which is based on nonlinear phenomena overclocking transmission, or an acoustic radiation pressure.
In other words, once the object interrupting the transmission of ultrasonic pressure field acting on the object will be above the objects mentioned here is that we the majority of users of a body part. New Orleans in 2009 in the United States Computer Drawing fairs, Tokyo University of the scientific team for this new technology on a detailed introduction.
Pressure wave transmission direction and ultrasonic transmission direction is the same, we also believe that ultrasound can "blow" to block objects. The user's finger touch to these holographic images, or is the ultrasound, they will feel a slight finger pressure, which before the touch of holographic technology in the fingers feel the air is completely different.
Order to better track the movement of finger position, University of Tokyo scientists have also applied the Wiimote (Nintendo), which is a simple technique based on infrared cameras. It Pjtime.com understanding, reverse transmitter used to track the user's middle finger, apply two Wiimote is to lock the finger at the top of the 3D position. With the help of this finger tracking technology, users can use their fingers to touch the screen suspended in the air.
Not just the visual experience, which improved holographic touch program also gives customers a real tactile feel, the tactile feel or the establishment of the digital data based on changes. This video game, 3DCAD, digital signage and many other industries are helping greatly.
"Scientists with the University of Tokyo team is very historic, this holographic technology to improve our product line is also a great help", Provision CurtThornton said of CEO, "We are innovative and improved the tactile feedback technology to make holographic images can react with the user's finger. collaborators University of Tokyo, for the birth of this improved technology to pay a great deal of effort for the development of holographic technology has opened up a new way, and make the majority of users were watching the hologram interactive experience.
