Interactive experience in past and present life

After dinner to go for a walk, see the downstairs children holding the ipad stamp to delimit, sigh now the child is really happy. And do not say that silk foot food nutrition surplus, in the entertainment, education means, also unprecedented rich. The popularity of tablets and touch devices, while entertaining, has also contributed to the evolution of current interactive devices. By watching the kids play the ipad compared to how we used to play games as a kid, we can find that from simple child's treasure transformers, Rubik's Cube and other children's toys, radio TV and other media products, controller connected to the game machine, and then through the keyboard and mouse operation of the PC, now to touch screen flying mobile devices, The interactive experience of the product has also been changing.

From the early interactive devices such as perforated paper tape, panel switch and display lamp, the interactive devices, such as sight tracing, speech recognition, touch feedback, augmented reality (augmented reality), and so on, are developed to the future virtual reality. The development of user interaction interface after batch processing, command line, graphic interface three stages, will gradually disappear, the artificial human-computer interaction will be more direct, without a special interface as a medium, into the human brain interaction phase.

"If someone pulls the plug, I'll disappear." "Film ' The Thirteenth Floor ' in a classic line, describes the virtual world of sensual pleasures behind the glitz, computer chips and computer programs, the cold combination of the plot to sound even if very sad, because all around the bustling beauty and criss-cross are virtual, But it is still the most extreme experience in people's imagination. Countless sci-fi movies are looking forward to the ultimate experience of the future world will be after the brain intubation or matrix virtual Reality (reality), the requirements of the interactive device, but also gradually from the use of screen controller to throw all peripherals, feel the experience of the line.

According to my personal understanding, I divide the development of the interaction into the following three stages:

1. Interactive character

2. Human-Computer Interaction

3. Human brain Interaction

The current Internet product interaction design is mainly focused on the second stage, this article focuses on this, the other two stages is simply introduced.

1. People interaction

Character interaction means that people interact with the product itself, the object of interaction is the product itself, such as hardware tools, toys and equipment. This kind of interaction is more intuitive, more direct physical contact Product ontology, people and product interaction is also more in line with the cognitive habits, so generally will not occur interaction barriers. Take the hammer will go to knock, hold the screwdriver to go to twist, magnifying glass can be seen through the lens to see the magnified object, lock buckle close that can be locked, shopping cart light push can move forward ... This part of the interactive design is a hardware design or industrial design category, considering whether the shape conforms to people's use habits and operating comfort, the product process and metaphor mapping also have certain requirements.

2. Human-Computer Interaction

Human-Computer interaction is the process of transferring and exchanging information between people and electronic products by means of communication between people and electronic products. Because the electronic product has the Man-machine interface, so the basic interaction is the process of input and output through it. This is an indirect interaction, the media is the human-computer interface, human consciousness and instruction through the Man-machine interface input, the product received by the Man-machine interface output feedback.

We expand the human-computer interaction by the distance of the input and output distances, the following several ways:

Interacting through the product ontology

Because the distance of the interaction object, interactive effect is the most direct, the learning cost is relatively low, belong to the user more easy to master the way. Especially for electronic products, the presentation of all its content and the function of the play are dependent on the I/O interface, generally with the product on the I/O interface as an interactive object, the physical interface of the product as an interactive interface, leading people to find the manipulation of the law and achieve interaction. such as calculators, meters, mobile phones and other electronic products on the switch, buttons, touch screen and so on.

Switch interaction is single and effective, the purpose is strong, but not rich enough, and many functions can not be a simple 0 and one judge. Wouldn't it be tedious to ask you to open a switch to complete a function of dialing a family call?

Keys can provide a direct and effective way to start the command, not easily ambiguous, but the keys can not quickly meet the high-precision positioning requirements. Do you have the courage to try to determine a specific landmark in a vast map by pressing the key?

Touch screen has greatly improved the user interaction experience, not only the performance content will change with the screen, and whether the finger or touch pen, positioning is more convenient, easy to get started. As a result, many portable devices now use touch as their preferred mode of interaction.

Touch screen also has some deficiencies,

1, the finger in the operation of blocking the line of sight.

2, only visual feedback and lack of tactile feedback led to cold touch screen force feedback feel bad.

3. The touch accuracy needs to be improved.

4, the lack of meta-key support led to a lot of fast function missing.

In addition, because the human-computer interaction is spread out on a flat surface, and the screen range is limited, touch-screen products give people a sense of lack of space when interacting. And how to realize three-dimensional interactive operation on two-dimensional plane, including the smooth switching of different visual angle, the visual display of different angle, has put forward the high request to the interactive design. The experience of playing the first person shooter on the touchscreen has haunted me so far, let me feel as an outsider, through a bad control way, to try to pay attention to the human-machine control of the game, the confusion of space and drag the target of the obscure hand, so I abandoned most of the touch platform 3D game.

Interacting with a control device connected to a product

The appearance of the control equipment connected with the product frees people from the product itself and pays more attention to the experience of using. Such methods include remote consoles, handles, remote controls, keyboards and mice, and so on.

To everyone common keyboard mouse for example, the keyboard is the main input tool, especially in the text information input has other interactive mode incomparable advantages, while the mouse is the graphical control interface the most convenient and efficient interactive tools, through simple learning, Anyone who has no experience in computer use can master the basic operation and interactive mode of the mouse very well. Although in 2008, Bill Gates introduced the concept of "natural user Interface" (Natural user interface), predicting that the mode of human-computer interaction will be greatly improved in the next few years, the keyboard and mouse will gradually be more natural, more intuitive touch-type, Visual and voice-activated interfaces instead. But architects need to use this equipment for building accurate modeling, database experts need to use this equipment for complex data entry, writers need to use this device for long-term writing, engineers need to use this set of equipment design and programming ... So at the moment, the keyboard and mouse in the personal computer interactive mainstream status can not be shaken for several years. This kind of traditional controller has a certain distance with the display content, this kind of distance feels with the good control feeling sometimes can produce a joyful experience, also lets the person unforgettable.

The disadvantage is that, due to the deviation caused by distance, the human-computer interaction process is not natural, and the long-term repeated operation of the controller is easy to cause the mouse hand, handle refers to the operation of computer and other diseases caused.

Direct remote interaction with the product through the human body

The human individual has common perceptual characteristics. By studying user behavior and analyzing the main tasks of interactive design, we are familiar with the basic sensory perception of human beings, which can be divided into sight, hearing, smell, taste and touch. Human beings identify the various attributes of the outside world by feeling, such as sound, movement, material, weight, smell and so on, to form a complex cognitive process. It can be said that the ultimate human-computer interaction is transmitted through the induction, the main manifestations of eye movement tracking, motion recognition, voice control, tactile interaction, geo-spatial tracking and other body sense of interaction. Through infrared scanning, thermal induction, sound image recognition analysis, image tracking algorithm and space physical location technology, it can make people better use their actions to send instructions to the machine to achieve the perfect state of human-machine unity.

The interactive pursuit of body sense, the game industry always go in the first row, following Nintendo launched on November 19, 2006 with the body Sense controller game host Wii,sony in September 2010 launched a high-precision dynamic body sensing controller PlayStation Move, Microsoft on November 4, 2010 launched the XBOX360 gaming console peripheral Peripherals Kinect. Kinect completely abandons any outside device, and in a revolutionary way, interacts with the physical sense of the player's life. Not only can identify the player's body movements, but also can identify the player's voice, as Microsoft's slogan "You are the controller" said, you are the controller, you will never sit on the sofa, do not need to adapt to the game handle on the joystick and buttons, With the body and language can directly control the game, easy to use, easy and direct, without restraint.

In addition, augmented reality (augmented reality), which has arisen in recent years, is also a way to see the real world with virtualization technology. By providing deep information that is not directly visible in the real world, augmented reality has led to a clearer display of the diverse world in front of people. The University of Columbia Graphics and user Interface Lab website helps American Marine to apply augmented reality technology to armored turret-assisted maintenance, which enables maintenance personnel to obtain more useful ancillary information in maintenance through a head-and-wear monitor.

In other areas, augmented reality has also been developed in a significant way:

Education: Establish the direct interaction between students and teachers in the online classroom.

Entertainment: Playstation EyeToy has demonstrated the great impact of augmented reality on entertainment, whether it is ' eyepet ' intimate interaction with a virtual pet or a ' judgment eye ', which combines the virtual role and the card in a perfect combination, allowing people to feel the interactive evolution brought about by technological progress.

Medical: Doctors can use augmented reality to remotely instruct patients to solve problems.

Navigation: Cyclopedia is an app that uses augmented reality to enhance real-world display on iOS, and has dropped a camera, and what you see here is from Wikipedia, a powerful message that is useful for enhancing virtual navigation.

Even though there are still not enough precision, from time to error recognition, fatigue and other defects, body sense of interaction is the highest experience of the human-computer interaction phase.

3. Human brain Interaction

Including mind control (Mind controls) and virtual reality in the brain.

Mind control mainly uses brain wave detection technology to build brain-machine interaction, machines to detect the brain's thoughts, predicting the next step. Common in science fiction movies or game fields, such as the movie Ant Empire, the ants use white gas to control humans, the game ' StarCraft ' inside the Protoss dark Archon (Protoss Dark Archon) 's mind control ability allows him to control enemy units freely.

Virtual reality in the brain is the ultimate experience mode in many sci-fi movies, that is, the use of computer to produce a variety of human organs sensory function, people immersed in the virtual world. In this case, the main interaction occurs between the human brain and the sensory functions of each organ, and the electron pulses or sensors transmit different sensations through the brain to the human body, thus creating all sorts of wonderful lifelike experiences. In this case, people do not need to use physical entities to interact with it in the brain, bring the illusion also true on-the-spot experience is the ultimate goal of the user experience pursuit. This is a new technology that has just started and has far-reaching potential applications. The matrix in the matrix is a huge network, where the system is assigned to different roles, and the human body is placed in a container full of nutrients, filled with plugs to receive a computer's sensory stimuli. Humans rely on these signals to live in a completely virtual computer vision ...

Human brain interaction is still in its infancy, because of its technical complexity and ethical controversy, so we can only in science fiction, movies, video games, entertainment to see their figure. It is its own double-edged sword effect, the technology in the diplomatic, war, political and religious areas of the future can not be estimated, but in the civil, living, communications and other areas of development is still worth looking forward to.

Summarize

Character interaction

The most basic direct way of interaction, easy to learn. Long-time use of fatigue, misoperation will bring some risks, such as the use of knives will accidentally cut hands, objects will have physical loss to shorten the service life.

Interactive

Indirect interaction through a human-computer interface makes it easy for computers to recover from faulty operations and to help with repetitive tasks. The indirect interaction makes the reality feel lower, while the interaction mode is limited, and many interactive ways need to be learned.

Human brain Interaction

It is the ultimate stage of interactive experience to interact with the center of thinking, to make many forms of interaction which are impossible in reality and not to operate the risk of misoperation. At present, the development only starts, the key technology is not formed, the equipment cost is high, many virtual interaction behaviors are restrained by moral and ethical disputes.

Three kinds of interactive ways can not replace each other, but coexist, constantly interwoven development.
