Human-Computer InteracTIon (HCI) is mainly to study the exchange of information between humans and computers. It mainly includes two parts: human to computer and computer to human information exchange. It is a comprehensive discipline closely related to cognitive psychology, ergonomics, multimedia technology, and virtual reality technology. The exchange of information between people and computers mainly depends on interactive devices, mainly including (1) human-to-computer interaction devices: keyboard, mouse, joystick, joystick, data clothing, eye tracker, position tracker, data gloves And pressure pens, etc.; (2) computer-to-human interaction devices: printers, plotters, displays, head-mounted displays, and speakers. Interactive technology classification of human-computer interaction: (1) basic interaction technology; (2) graphic interaction technology; (3) voice interaction technology; (4) somatosensory interaction technology.
2. Three revolutions in human-computer interaction: mouse--"multi-touch"--soso-sense technologyThree revolutions in human-computer interaction under the two-wheel drive of technology and demand. With the rapid development of information technology, human-computer interaction technology has achieved three major revolutions, (1) mouse; (2) multi-touch; (3) somatosensory technology.
Mouse: Apple designed the world's first popular mouse "Lisa", which is better than position indication
The keyboard is more humanized and is the ancestor of "natural human-computer interaction". Then the mouse gradually becomes the standard of the computer; multi-touch: Apple pushes multi-touch to the public. Subverting the traditional "interaction mode" brings a new gesture-based interactive experience.
Somatosensory technology: Kinect is hailed as the epoch-making product of the third generation of human-computer interaction. It utilizes functions such as instant dynamic capture, impact recognition, microphone input, and voice recognition to achieve a new experience that does not require any handheld device for human-computer interaction.
From the previous human-computer interaction revolution to predict the development trend of human-computer interaction, the development of human-computer interaction is mainly reflected in the change of interaction concept and the upgrade of interactive equipment. (1) Interaction concept: 1 passively accept information--active understanding of information; 2 Meet the basic functions - "emphasize the user experience. (2) Interactive equipment: mainly depends on changes in input and output, 1 mode is naturalized; 2 content is diversified. Intelligent interaction technology: Human-computer interaction technology driven by big data and cloud computing is a major development trend. Through the massive processing of interactive data, a “interactive material†database is formed to build a smart interactive cloud platform. Under this platform, users and computers pass Various devices implement natural interactions.
4. Development trends and prospects of interactive devices : The explosive growth opportunities in the gradual standardization of somatosensory devicesSomatosensory interaction device: It is a kind of interaction with a surrounding device or environment through gestures, limb movements, etc. of the user without using any complicated control device. The actions performed by the limbs are sensed by the somatosensory sensing device, and the specific motion trajectories of the human body are known through data processing and algorithms and reflected in the device or the environment, and the virtual space can be interacted with by the somatosensory device without contact.
Concern 2: Wearable devices enter the tens of billions of dollars market in the next few yearsWearable device classification: Wearable devices are mainly divided into four categories: wearable consumer devices, wearables and general devices, wearable healthcare devices, wearable industries and military devices. Currently, wearable device products are mainly concentrated in the fields of fitness and health care, information, medical and health care, and industrial and military.
The global wearable devices are frequent, and the production chain will continue to be booming: wearable smart devices are an important innovation direction after smart terminals such as smartphones and tablets, along with Google Glass, iwatch, smart wristbands, and wearable heart monitoring. The launch of star products such as equipment has gradually attracted attention and become a hot spot in the market.
Concern three: the development trend of multi-modal interactive devices
The multi-modal interaction device is a parallel interaction device of multiple interaction modes, such as voice interaction, somatosensory interaction, and touch interaction. Human-computer interaction based on multi-modal interaction devices: collecting user information through various tracking modules (face, gesture, posture, voice, and rhythm) in the interactive device, and understanding, processing, and managing to form a virtual user expression module , interactive dialogue with the computer, can greatly enhance the user's interactive experience.
Google Glass leads the era of multi-modal interaction. In April 2012, Google released an "Expanding Reality" glasses that has the same functions as a smartphone, allowing you to control photos, video calls and directions, as well as surfing the Internet, processing text messages and e-mails. The eyes choose a variety of functions.
