With the advancement of technology, the human-computer interaction technology integrated by smart TV has become more and more diverse, such as voice recognition, face recognition, and gesture and somatosensory control, which can be widely used, and can be combined with TV application (App) and peripheral devices. To create a simpler intuition for users, and to take into account the information security and privacy protection of the control experience. Since the advent of television, it has become synonymous with home entertainment. Even though many 3C products have TV-like entertainment functions, they still cannot replace the status of TV. There are two important milestones in the history of television development. The first is the evolution of black-and-white television into a color TV and remote control. These two evolutions have also laid an important foundation for the development of human-computer interaction technology. Due to the popularity of the network and the increase of the transmission speed, along with the digitization of the signal, the TV gradually evolved into a two-way human-computer interaction by a one-way interaction mode of receiving and playing video and sound. The MIC predicts that by 2015, the penetration rate of the smart TV market that supports networking will be close to 50%, and the key to the success of three smart TVs: the intuition and simple human-machine interface (UI), the number of applications With the quality, and the ability to interact with other smart devices, these three key factors are related to human-computer interaction. Borrow the mirror popular 3C smart TV UI function imagine unlimited In the past 10 years, many 3C products have made breakthroughs, including smartphones, tablet devices, TV game instruments, etc., as well as personal computer hardware performance and operating systems are constantly improving. However, in contrast to the development of television in the last 10 years, until 2010, smart TV took off slowly. The following will discuss the most popular 3C products today, which human-computer interaction technology can be used for smart TV - Figure 1 lists the personal computer (PC), TV game and mobile devices for smart TV to borrow all kinds of human-computer interaction technology. Figure 1 Personal computer, TV game and mobile device for human-computer interaction related technology. 3C product design concept comes from PC Although it has entered the post-PC era, many modern 3C products are inspired by personal computers, such as the remote control with Qwerty keyboard and trackpad. The Sony NSZ-GS7 and Vizio Co-Star Google TV set-top box remote control combines the touchpad with the Qwerty keyboard on the back. Also worth noting is LEAP MOTION, which supports both Windows and Mac operating systems and connects to a computer via Universal Serial Bus (USB) 3.0. Through it, you can use your fingers to command the computer, as if you were taking drugs from the air, and its accuracy can achieve the accuracy of drawing lines within 1 square centimeter area; plus no contact with the screen, so there will be no fingerprints. The problem. Another feature of personal computers is the powerful computing and networking capabilities, the ability to connect different peripherals, and the ability to easily install software applications; the peripheral hardware and software applications can extend the functionality of the computer itself. The App Store is basically derived from the concept of software installation, but the App Store is installed through the network, which enhances convenience. The connection between the personal computer and the surrounding is also the most diverse. The wired connection methods for smart TV include USB, Ethernet, high-definition multimedia interface (HDMI), etc., while wireless communication technology, There are wireless area networks (Wi-Fi), Bluetooth, infrared, and so on. TV game instrument sense / community interaction popular market When it comes to the human-computer interaction of TV game instruments, you must mention the Wii released by Nintendo in 2006. Its nunchaku-like analog controller allows users to play TV games no longer just Moving the finger, it enters the somatosensory control, which introduces the concept of operation that moves the whole body. Wi-Fi to some peripherals to add different somatosensory operating experience, like the Wii Fit is a typical representative, it is a board with sensors, through which you can add more interaction in the game, also The user's actions can be scored through the sensor, and it is believed that the smart TV will introduce similar concepts to increase the human-computer interaction experience. Wii U also incorporates the GamePad controller with touch screen. In addition, it also has built-in three-axis acceleration sensor and three-axis gyroscope, camera, infrared sensor strip, and supports Bluetooth and Near Field Communication (NFC) transmission technology. . It can also be combined with Wii's controller and Wii Fit to give users a full multi-screen interactive experience. Smart TVs can also use similar concepts to combine smartphones and tablets to achieve multi-screen interaction. Another breakthrough development of the somatosensory controller is the Kinect, which was released in 2010. It is the periphery of Microsoft's Xbox 360 TV game. The word Kinect is derived from KineTIcs plus ConnecTIon. . The Kinect has three lenses, the middle lens is a color camera, and the left and right lenses are respectively a three-dimensional (3D) structured light depth sensor composed of an infrared emitter and an infrared complementary metal oxide semiconductor (CMOS) camera. In addition, it is also equipped with tracking focus technology, the base motor will follow the focus object to move together. Microsoft released the Xbox One in 2013 with an upgraded Kinect featuring a 1,080p high-definition wide-angle photographic lens and a more accurate sensing device that can simultaneously track up to six people, including detecting gestures and even detecting Muscle activity and heartbeat. Sony's PS 4 also joins the PlayStaTIon 4 Eye, a Kinect-like device that uses a high-resolution dual-lens lens to capture images from two sets of lenses and uses stereoscopic algorithms to calculate the distance between the object and the Kinect. It also has 3D depth front and rear detection functions, but they are equipped with different technologies and are equipped with radio microphones. Therefore, there must be more video recognition applications in the future. The network connection of TV game instruments and community interaction is also a smart TV. The latest 8th generation TV game instruments (Wii U, PS4 and Xbox One), in addition to the host company's exclusive social networking site, also support Public social networking sites like YouTube or Facebook, such as PS4, can broadcast live through Ustream, and upload broken screens to YouTube or Facebook. When the game is closed, the control authority can be handed over to the remote expert to assist in the break. Similar instant sharing and interaction can also be used by smart TV. Mobile device set networking / video / UI Dacheng Mobile devices mainly include smartphones and tablet devices. 2007 and 2008 are the key to the development of mobile devices. The advent of the iPhone and iPad has created a whirlwind of smartphones and tablet devices. Some of its human-computer interactions are attributed to the wireless network and the cloud ecosystem. The most important thing in the cloud ecosystem is the App Store, which allows mobile phones to expand their capabilities by simply connecting to the App Store to download applications over the wireless network. Therefore, 3C products only need to be smart with two words. In simple terms, they have networking capabilities, and the App Store can download applications or related digital content (such as movies or e-books) to expand the functions of the device. Another iPhone and iPad is the most talked about, because its user interface is compared to the earlier smartphones and tablet devices, in addition to aesthetics, it also takes the humanized mobile phone and tablet device as the starting point, instead of The graphical interface of the desktop is reduced and moved to a smartphone or tablet, and simplified to the point where people can intuitively operate with their fingers. Anyone who has written a program for an iPhone or iPad knows that Apple has an iOS Human Interface Guidelines that define the optimal button size and the best human-computer interactive graphical interface. Design rules. So the same, if the human-computer interaction of smart TV is to be more simplified, we must pay attention to every detail to be successful. Voice control is also an important part, because the most efficient way of communication for human beings is to talk directly. Siri introduced by iOS 5 is the representative of intelligent voice assistant; Siri of iOS 6 starts to support Chinese, but the service of Chinese is better than The United States is obviously limited. To use the power of the voice assistant, it must be integrated with the database on the cloud to provide the most effective and immediate information. Another point is that Siri can only identify the single language that is set. It is impossible to identify the sounds of the two languages. It may be possible to support the mixed recognition between Chinese and English in the future. Smartphones and tablet devices can mirror the technology projected on the screens of other devices. Apple's AirPlay is a representative that can output iPhone and iPad images to the Mac screen. If the TV is connected to Apple TV, it will be able to The iPhone and iPad video is projected onto the TV, and there are also apps that support AirPlay on Android. Sony Touch TV's One Touch Mirroring function is similar to AirPlay, and as long as the NFC function on the Sony Xperia phone is turned on and the phone is placed close to the back of the smart TV remote control, the screen content of the phone can be projected onto the smart TV to the smart TV. The human-computer interaction model that integrates 3C devices for the center will be more popular.
