New technology and trend of touch screen

--A simple, convenient and natural human-computer interaction mode

Introduction

The popularity of touch screen applications has successfully opened the door to the era of human-computer interaction. As a simple, convenient and natural human-computer interaction mode, it has been widely used in many fields, such as public information query, industrial control, military command, multimedia teaching, etc., and has become an important tool for people to obtain information in daily life. The rapid expansion of the application market scale has directly driven the enthusiasm of manufacturers, and new technologies and trends are emerging.

New technology • technology upgrading brings diversified forms

With the continuous improvement of the market's recognition of human-computer interaction concept, the application of touch screen is no longer satisfied with primary touch and sliding. More intuitive and amazing use effect has become the goal of technology research and development of touch screen enterprises.

1. 3D haptic feedback screen--Microsoft R&D launched in 2013 for medical and gaming
   It combines an LCD flat display screen, a force sensor and a mechanical arm that moves the screen back and forth. By controlling the resistance to the user's fingertips, it simulates the shape and weight of the object on the screen, and adjusts the position of the screen to match the contour of the virtual object, so that people can feel the shape of the object. Then, the computer will adjust the size and angle of the image on the screen to form a 3D effect, and the user can obtain a stereoscopic visual effect through special glasses.
   
2. Touch screen projected on water vapor--Russian R&D launched environmental protection and low energy consumption in 2013
   Its principle is to display the image through air humidification, which can respond to the interactive gestures read by the sensor in the display screen. Users can operate the transparent touch screen through gestures, which can complete image processing. Moreover, the screen can be preconfigured to use format application programs. Moreover, humidified air is good for skin.
   
3. Double touch technology -- Hanwang launched a user-friendly experience of easy page turning
   This technology was introduced by Hanwang, which can realize the third generation of electromagnetic pen and finger double operation, making up for the previous blank of E-INK screen finger touch technology, meeting the user's needs of turning pages with fingers and pen, and bringing users a more humanistic interactive experience.
   
4. Floating touch screen -- Sony R&D launched free control in 2012
   It can detect the instructions issued when the finger touches the screen, and can also recognize the actions carried out by suspending the finger above the screen. As long as the finger is suspended within 20 mm above the user interface, it is not necessary to touch the screen to realize various operations on the screen display content. It is worth mentioning that the screen can sense non-conductive fabric, and can still be freely manipulated even after wearing gloves in winter.
   
5. Somatosensory interaction -- realize page turning, sliding, confirmation and other operations
   The somatosensory interaction is to sense the viewer standing in front of the window through the hardware interaction device, the somatosensory interaction system software and 3D digital content. When the action of the viewer changes, the screen displayed in the window changes at the same time. In actual operation, the operator can control the system through his/her own limbs to realize operations such as page turning, sliding and confirmation.
   
6. Double sided touch screen technology
   It is newly developed by the Korean Academy of Science and Technology, meeting the requirements of simultaneous touch operation by multiple people. This touch screen is named Transwall. Its shape is similar to a transparent white board, and it is fixed by a T-shaped frame. An infrared touch sensor is added to the frame to detect touch operations from users. The information detected by the sensor is then sent to a computer, which will process the data and project the operations back to the screen through a projector installed on the frame, so as to achieve the effect of double-sided touch.
   
7. Tactile feedback technology
   The haptic feedback technology is developed by Disney. With the help of the touch screen of this technology, users can really feel the display objects in the touch screen. The basic principle of this technology is that when the user's finger crosses the image of the touch screen, the mechanical friction sensitive point on the skin will detect the real-time change of the image surface, and then the change of friction between the finger and the touch image will make the user feel like touching the real object.
   
8. UltraHaptics system
   Traditional touch systems are different. With the UltraHaptics system, users can achieve touch operations without actually touching the touch screen. Essentially, it is a force field that allows touch feedback with interactive technology, which mainly depends on sound radiation. The ultrasonic vibration makes the user's hand in the air feel touched.
   
   

Summary

In essence, the emergence of touch technology is to better meet people's needs for human-computer interaction experience, so that the screen display can change from one-way communication to two-way interaction, and achieve a more intelligent application experience. It is precisely because of this, with the continuous progress of science and technology and the continuous improvement of people's human-computer interaction needs, touch technology is constantly upgrading, while the form is more and more diversified.

New trend • diversified forms support the expanding market

In the realized display field, whether it is consumer electronic display represented by smart phones and tablets,  or commercial large screen display represented by interactive digital signs, touch display has become a trend. With thde increasing investment of manufacturers and the increasing awareness of industry users, the touch application market has become a veritable "potential stock".
