In general, most people cannot resist the temptation of new things and the pursuit of novelty can be seen as the instinct of human beings. When people are excited about the news that they can see shows on TV, which is just like a small box, they’ve never expected that one day they should touch the screen by their own hands to play games, order meals and tickets and many other things. The touchscreen technology leads us to the electronic society and brings lots of convenience to us which saves us large quantities of time. The society and we common people welcome the new technology.
Touchscreen monitors have become more and more commonplace as their price has steadily dropped over the past decade. There are three basic systems that are used to recognize a person’s touch:
- Resistive
- Capacitive
- Surface acoustic wave
The resistive system consists of a normal glass panel that is covered with a conductive and a resistive metallic layer. These two layers are held apart by spacers, and a scratch-resistant layer is placed on top of the whole setup. An electrical current runs through the two layers while the monitor is operational. When a user touches the screen, the two layers make contact in that exact spot. In the capacitive system, a layer that stores electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases. On the monitor of a surface acoustic, two transducers (one receiving and one sending) are placed along the x and y axes of the monitor’s glass plate.
The development of touchscreen opens a new era in human society and marks a big step in its progress. It is the achievement of the progress of science and technology, and strengthens our confidence in keeping on moving forward. As it develops step by step, the technology penetrates into more and more areas.
Multi Touch is a leading developer of interactive display systems, based on proprietary software and hardware designs. Multi touch displays are Full HD LCDs, stackable into any size table or wall and support multiuser environments. Software provides unlimited touch points, hand recognition, and object recognition on Windows, Linux and OS X. Multi Touch products are currently in use in more than 40 countries around the world. The products are designed for retail, exhibition, marketing, museum, public information, hospitality, research, education, art, design and other professional uses. George Harrison’s widow Olivia hopes to add more perspective on the reticent Beatle with her new digital book, and fill in the blanks left by Martin Scorsese’s recent documentary. Based on Scorsese’s “George Harrison: Living in the Material World,” the multi-touch book of the same name is available Tuesday on iBookstore. It includes audio, video material from the film along with personal photographs, letters, and memorabilia never seen by the public (a traditional print edition of the book has been in stores).
It’s obviously that the multi touch technology represents a giant leap and brings us lots of surprise. In modern times, everything develops at a striking speed. Of course, the touchscreen technology is of no exception. The appearance of the multi touch wall is the best proof of human wisdom.
Apple iPhone and Microsoft Surface have recently brought the multi touch wall technology into the spotlight, though research and development in connection with multi-touch have been around since the 80s. Our aim is to create a prototype through which we can research and develop new modes of users’ interaction. These interfaces have a great transforming potential for larger scale collaborative public interfaces, as well as for cell phones. This technology has been in the spotlight in the recent months as several products have claimed some sort of authorship about it, even touch research about multi touch has been around for decades.
With the rapid development of touchscreen and multi touch wall technology, we get the idea that new products are based on the old ones. Every little improvement represents a little progress. We are willing to experience the new products and expect better ones. The rapid development of science and technology brings our human beings into a whole new world. And we have to marvel at the creativity of human beings. As we all know, the modern society is a fast paced society. One who keeps on updating his brain, then he will be succeeded and not fall behind. We have enough reasons to believe that our future will be better.
