Modern electronic devices are equipped with all the new features that are designed to facilitate their use. Each characteristic has its own name. For example, you can find the word "multitouch" in the technical description of the tablet or phone. What it is?
Term meaning
First of all, it's worth noting that this is the name of the touch screen. Such a monitor responds to easy finger tapping and does not have a physical keyboard. In English, the term means "multiple touches".
History of occurrence
The first experiments on the creation of touch screens were carried out back in the 1960s. Later they found their application at CERN. They were equipped with an accelerator of elementary particles. In the 1970s, the screen of the touchscreen was presented at the University of Kentucky. Modern technology, which once seemed fantastic, appeared in New York. It was developed by Jeff Khan. This happened eight years ago. It can be said that the new possibilities for creating touch screens of "many touches" arose precisely at the beginning of the 21st century. The inventor organized his company, which he called "Perceptive Pixel". Very quickly, she merged with Microsoft and began to develop programs that are part of the Office suite.
What commands does the touch screen perform?
First of all, let's define the multi-touch features: what is it and what is the difference between the usual touch screen and it. The first is able to recognize the coordinates of the point of one touch, and the second - of the set. This circumstance makes it possible to make work with an electronic device more comfortable and productive. A lot of special gestures for device management have been developed. If you have a smartphone, you should remember that with just two fingers that converge or diverge on the monitor of the electronic gadget, you can set the command to zoom in or out. They also allow you to open folders, files, minimize, move them, rotate, scroll pages. You can enter text using the virtual keyboard. Manufacturers of mobile electronic devices (particularly smartphones) indicate that their screen is capable of recognizing up to twenty touches. To test the multitouch screen for the accuracy of this statement, there is a special test program. It is free and is freely available on the Internet. It is often used by owners of devices with the operating system "Android".
Electronic devices with multitouch
Typically, this technology is supported by many modern mobile electronic devices: smart phones, telephones, e-books, iPad and even laptops. They are produced by popular companies, for example, companies such as Apple, Dell, Microsoft, Hewlett-Packard and others. There are several options for manufacturing touch screens. The most popular technology used resistive technology. It was developed by Sam Hurst. Its biggest plus is the low cost of production. This continued until 2008. Other options for creating similar displays: optical, strain-gauge, inductive touchscreens. Now create a projection capacitive touch screen. They are used by Apple in their iPhones and iPads.
Display Device
What does the multitouch screen consist of? A capacitive monitor is a glass panel covered by a resistive layer. At the corners of the display there are four electrodes. An alternating voltage passes through them. When the finger touches the touch screen, a leakage current occurs. Large screens with multi-touch support the function of tracking multiple touches of multiple users simultaneously. It can have displays created by various technologies. Developed and launched in the production of IR-frames - screens with different diagonal, with the use of infrared illumination and camera. Consumers in electronics are in demand with special sensory films, as well as glass. They cover the displays, their sizes can be from seventeen to fifty inches or more.
Where are touch screens applied?
Modern technology has become familiar and convenient multitouch technology. That this is part of the interface of the best novelties in electronics, even children know. It is considered a big plus if the device is controlled by touching. Very actively carried out the development, which is designed to improve this popular technology. In everyday life, touch panels can be found in shopping centers, medical centers, universities, schools, railway stations. They are used as a means of advertising services and informing customers. And, the visitor of an institution can choose, browse the catalog of goods, rotate, move files. Similar panels are manufactured by Philips. This multitouch system is equipped with speakers and a microphone. The monitor features high contrast, its surface is resistant to damage and the appearance of scratches. The panel works in two modes: streaming (video, flash graphics, animation) and interactive (online management). For a company that uses such devices, this is a great opportunity to raise your prestige in the eyes of partners and customers.
What are their advantages?
Firm "Apple" used in its phones and iPhones the technology of multiple touch. As a result, gadgets equipped with touch screens have become very popular with buyers. Microsoft is using multitouch on the desktop of its operating systems and considers this direction to be the most promising. If you use devices with a multitouch display, what it is and what is its advantage, you will soon be able to answer independently. First of all, it's easy to manage multiple finger touches. As a rule, the screen of electronic gadgets is large. The lack of physical buttons does not interfere with their operation. On the contrary, it allows making electronic devices the most comfortable, it is a pleasure to use the Internet, to start audio or video files. If there are special programs, there is a possibility of simultaneous operation of the device by several users. This interface makes management intuitive. Therefore, touch screens are suitable for children, and for advanced youth, and for the elderly.
Customer Reviews
Users of electronics with a touch screen are left with only the best impressions of communicating with it. After all, this monitor allows you to expand the ability to manage files, gadget functions. The company "Apple" produces a tablet, which, in addition to the mass of positive characteristics, also has a screen that is protected from the appearance of fingerprints. This is promoted by the oleophobic coating. Therefore, the device is not only comfortable, but also beautiful. Having communicated with him one day, the buyers lose the desire to look for something else. Very convenient capacitive multi-touch for fans of games.
The future of technology
The inventor of touch screens Jeff Hahn believes that at present there are several directions on which this technology can develop. Developers still have to create giant-sized displays, controlled by touch. This will make them available to multiple users at the same time. Probably, a touch multi-touch with the pen will be connected. This will solve problems that require a more subtle approach. After all, human fingers sometimes act fairly rudely. And with the help of a special object you can draw on the display. In this case, both hands of the person will be involved. So, the left one can affect the scale of the image, resize the windows, move them, and right write with a pen. Presently existing tablets equipped with touch screens do not meet the above requirements and are not yet sufficiently adapted to make it convenient to work with a pen and touching fingers simultaneously. First of all, their monitors are not large enough, it is inconvenient to work with both hands. The combination of two options for managing files (touch and pen) is not yet available. At the same time, the interfaces react very slowly to the effect of a special object. When the first multitouch touch screen appeared, many users had a feeling of discomfort when using devices equipped with a similar display. Many lacked a physical keyboard. Another step in the development of technology is the development of icons, objects, relief and texture which can be felt. Undoubtedly, it can be concluded that the future is for touch-sensitive displays. They personify the face of modern electronics.
