These high-tech future will replace the keyboard input devices

　1870s, when Christopher Latham. Shoals (Christopher Latham Sholes) invention QWERTY keyboard, he probably would not have thought his basic design philosophy has continued for 150 years, until the current era of digital, high-tech world changing. Computer keyboard never outset become the undisputed king of the input device. 
　　Recently there are foreign media of the future is likely to replace the keyboard input device of the sort, the article analyzes the existing and emerging concepts of what can bring the possibility of post-keyboard era, and were interpreted the gesture, voice, virtual, projection and other keywords.

　　Brain waves

　　Such fantasy future: brain waves and chip direct transmission, cyborg science fiction flavor blowing. Research on BCI (BCI) technology can be traced back nearly 50 years ago, but recent advances have this technology out of the lab. For example, NeuroSky's EEG biosensor allows the user to interact with the computer by simply wanted to trigger. 

　　Smart glasses

　　Perhaps the most promising smart glasses wearable input device, because it is from our main sensory organs - the eyes close, it brought a lot of possibilities of development. Most smart glasses using OHMD (optical head mounted display) technology, can be projected onto a screen in front of the picture, and then combined with other input methods Google glasses used voice commands system, OHMD can provide truly mobile viewing experience. Such as Swedish companies like Tobii eye-tracking system has been used as an input device solutions to use. By tracking the eye movement, the direction of travel is determined eyes, such systems can be used to execute the command, the traditional workstation applications, automotive and even video games. 

　　Smart bracelet

　　France, a small company produced a smart bracelet Cicret Bracelet is a new input device that combines the projection keyboard, wearable computers and mobile technology and other elements, the use of micro-projectors and proximity sensors, the skin as a touch screen. The device is still in the early prototype stage, as of now, the design team said that this bracelet allows the user to operate like other touch screen surface to click and slide the same. Expected bracelet is run independently of the Android system, or connect via Bluetooth and mobile phone with Wi-Fi capabilities and a built-in micro USB port. Oh, but be careful: if caught itch, you might recklessly text messages everywhere. 

　　Smart Ring

　　After the website Kickstarter to raise public appearance, smart ring Ring attracted a lot of attention, also caused a sensation on the Consumer Electronics Show in Las Vegas last year. As wearable input device, such ring via Bluetooth smart phones, smart watches, even after the networking devices are paired, you can allow the user to create some quick swing finger command and accomplish different tasks. For example, wearing a ring in the air, sending a text or write a letter spelling out "TV" to open the living room TV. Ring using gesture recognition, mini lights, tactile feedback technology, allowing users to realize the communication between different devices. LED flashing and vibrating alert if a user has successfully send a text or complete payment. The Japanese company hopes to develop Ring on sale this summer, this product, priced at about $ 30. 

　　Projection Keyboard

　　Usually in combination with a laser projection keyboard devices, sensors and infrared beam, a traditional QWERTY keyboard copy on a flat surface, that is, the virtual keyboard is projected on a surface. Its object is to provide a virtual full-size keyboard for a mobile device, to overcome the physical limitations of the inconvenience and enhance portability. This technique can also be used to project the piano. Last year, Japan launched the "Star Wars" robot R2-D2 prototype projection keyboard, the application of this concept to the extreme. 

　　Virtual Keyboard

　　AirType American creative team developed a virtual keyboard, the keyboard is still in the early prototype stage, the use of a set of sensors surround palm finger gesture input when tracking. The user can at any plane or no plane can be typed, sensor inputs for user-specific learning habits. The keyboard also provides dynamic correction and word prediction help. 

　　Speech Recognition

　　For decades, speech recognition technology has been trying to get involved in areas of the keyboard. Now you can easily say it out loud, why effortlessly Yi Zizi enter it? The answer is simple: For a long time, voice recognition unreliability is well known, the application will be in the software is a difficult task. It's just as accurate count 6-year-old baseball player pitching, as can be imagined ...... but in recent years, speech recognition this embarrassing situation has greatly changed, thanks to artificial intelligence and "deep learning "algorithm amazing progress. Currently these systems use natural language user interaction to promote the development of many technologies, designed for people with disabilities such as hands-free devices, automotive voice and Siri, Huna, Google Now virtual assistants and other mobile devices. Skype has recently been further improved to achieve - the use of machine learning and natural language interactive technology to achieve real-time translation between English and Spanish. 

　　Gesture Recognition

　　Have seen the science fiction movie "Minority Report," "Ender's Game" and "The Avengers," the audience must remember the following scenarios: standing in front of the eyes of the protagonist determination translucent 3D holographic displays, handsome waved palm to bring up the data needed, you can easily access through sliding, stretching and other gestures, zoom in or out. Such technology has been part appeared in the motion control and gesture recognition systems, Microsoft's Kinect somatosensory peripheral devices such as game consoles and high-end artificial intelligence research environment can be seen in this type of technology in sight. Figure Leap Motion is a somatosensory controller, used in conjunction with a standard keyboard to track movement of the finger, the sensitivity of 0.01 mm. But independent 3D holographic devices are still very far from reality.
