Since the computer appeared in a clumsy form of a giant, until now, it has become more and more integrated into people's daily life, and has been recognized as an indispensable important for solving major social problems such as medical care, education, scientific research, and environmental protection. tool. In the process of interaction from people gradually adapting to computers to computers constantly adapting to people, human-computer interaction technology is no longer limited to keyboard input and handle operation, but appears in a more novel way: tiny movements of fingers, sound waves in the air The vibration, the rotation of the eyes and the rotation of the tongue can realize the information transmission and complete the "conversation" between the person and the machine.
What is human-computer interaction technology?Human-Computer InteracTIon Techniques refers to the technology that enables people to talk to computers in an efficient way through computer input and output devices.
The human-computer interaction technology includes the machine providing a large amount of relevant information and prompting instructions through the output or display device, and the person inputting relevant information to the machine through the input device, answering questions and prompting instructions, and the like. Human-computer interaction technology is one of the important contents in the design of computer user interface. It is closely related to the fields of cognition, ergonomics, and psychology.
It also refers to the technology of connecting the neural signal and the electronic signal through the electrode to reach the human brain and the computer. It can be foreseen that the computer can even become a medium in the future, reaching the communication between the human brain and the human brain consciousness, that is, the soul. induction.
In 2008, Microsoft CEO Bill Gates proposed the concept of "natural user interface" and predicted that the human-computer interaction mode will be greatly improved in the next few years. The keyboard and mouse of the computer will gradually be more Natural, more intuitive touch, visual and voice-activated interfaces. With the advancement of technology, the "organic user interface" (organicuser interface) has begun to rise quietly - biometric sensors, skin monitors, and even the direct connection between the brain and the computer will undoubtedly have a major impact on human life. The article published in the May/June issue of Futurist magazine has taken stock of various types of human-computer interaction technologies that are currently being developed or put into commercial use.
Touch displayTouch-screen displays have been widely used in many fields. The most well-known is the Kiosk self-service device installed at the airport or shopping mall. Visitors or shoppers can check the relevant information, check-in, or even purchase by manually touching the screen. newspaper.
In 2007, Microsoft introduced the "Surface" computer, bringing a new touch-based human-computer interaction model. This tablet, which looks like a coffee table desktop, completely eliminates the mouse and keyboard, and can be edited, browsed, or ordered directly by voice, pen or touch. Its display screen is hidden under the hard plastic board, relying on a camera system to capture the command actions issued by the person, then analyze, understand and execute. What's even more amazing is that the computer can automatically recognize and transfer files as long as the phone, player and other items are placed on the surface. Since the "desktop" computer's screen can be split and multi-touch technology is used, it can be used by up to 10 users at the same time.
In June of this year, "Desktop" will usher in a strong rival, Sony plans to launch a coffee table computer called AtracTable with one of the higher. AtracTable can also interact with devices such as mobile phones placed on its surface. In addition, the computer also integrates age, gender, emotion and other analysis systems to intelligently identify the objects used. Sony's goal is to promote it to a variety of environments, including the gaming industry, industry, medical markets and retail.
Flexible displayThe ultra-thin, ultra-light flexible display has already left the lab and will soon enter the market to “play the mountainsâ€. Many commentators believe that e-books made with flexible displays that fold at random can be the future of paper.
At present, there are many types of flexible displays for e-book readers, including organic light-emitting diode (LOED) displays that can actively emit light but cause irritation and damage to the eyes of the reader, and liquid crystal displays that require background light ( LCD), and electronic paper manufactured by E-Ink Corporation of the United States using electrophoretic display technology on the Amazon Kindle e-book reader.
Different display technologies have their own advantages and disadvantages, so they have different application markets. For example, LOED displays have faster refresh rates, while E-Ink's electronic papers are more energy efficient. In the future, newspapers, magazines and even clothing and walls can be turned into display screens to show us a dynamic picture.
3D displayAlthough 3D movies have been around since 90 years ago, 2010 is the real "3D first year". Sony, Panasonic and other manufacturers have announced that their 3D TVs will be available for sale within the year, and 3D images will be available from the cinema. Moving into the living room is just around the corner.
Current 3D TV sets still require viewers to wear special glasses to watch the show. The specifications of the glasses are roughly classified into active shutter 3D glasses and polarized 3D glasses, and there is no general industrial standard, which is developed by each manufacturer.
Although the industry believes that the recent 3D movie sales in the global box office, indicating that the family market is ready to meet 3D, but whether the average audience can endure for several hours wearing special glasses to watch TV is still unknown. According to experts, 3D TVs that can watch programs without wearing glasses will probably wait another 10 years before they are introduced to the market.
Retina displayThe retina display can directly project images onto the user's retina through low-intensity lasers or light-emitting diodes, and has the feature of not blocking the field of view.
This concept was introduced more than 20 years ago, but until recent years, technological advances have made various retinal displays feasible. For example, a side-emitting LED, which has a higher light output power than a surface-emitting LED, but has a lower power requirement than a laser, and is applied to a retina display to provide a higher brightness and lower cost option. Compared to conventional displays, the retina display has a higher brightness-to-power ratio and a correspondingly lower power consumption.
The application prospects of retinal imaging are very broad. For example, a car head-up display can project important driving information on the front windshield of the car, and the driver can see it in a flat view, thereby improving driving safety. In addition, soldiers can perform military tasks. Provides optimal path and tactical information, and also has a lot to do in medical surgery and immersion games. The Japanese brother company showed the world's first retina display at the 2005 Aichi Expo in Japan. The company recently announced plans to release a commercial retinal imaging display using red, green and blue laser diodes this year.
Geospatial trackingThe application potential of geospatial tracking is just beginning to show, and huge technological advances are expected in the next few years. Smartphones equipped with GPS, directional meters and accelerometers provide enough information to help the user determine the approximate location and direction. Improvements in technology will make it possible to increase the accuracy of tracking to no more than 1 mm.
Many real-world enhancements for mobile phone development, such as location-based marketing, travel assistance, and social networking, use geospatial data to provide relevant information based on the user's location. In the next few years, this market will grow substantially as tracking accuracy is further improved and wireless networks are further accelerated.
Action recognition Motion recognition is a developing technology that can be applied in many ways, such as wearable computers, stealth technology, immersive games, and emotional computing (a way to detect, classify, organize, and analyze human emotions). The system or application that responds can help users get an efficient and intimate feeling). In the past, most motion recognition systems focused on facial and hand movements, but now researchers have begun to shift their focus to body posture, gait and other behaviors.
