What are the general research directions of HCI?

HCI (full name in English): human-computer interaction, means: human-computer interaction.

HCI is a discipline related to people, computers, and design.

HCI is about people. To a large extent, it focuses on the science and cognition of human behavior (rather than psychology in the traditional sense). HCI does not study the psychological dynamics of a single person, but rather why people do specific things in a broad sense.

In the early and mid-design phases, all decisions are made by studying user behavior.

HCI is about computers. Without inputs and outputs, without computer graphics, without algorithms, there would be no HCI.

HCI is all about design. But it's a mistake to think that human-computer interaction is learning to design pages, so that human-computer interaction is directly equivalent to design.

HCI is application-oriented, and it is essentially a multidisciplinary engineering application technology field. From the perspective of business applications, HCI can do the following aspects: software, hardware, interactive environment, Internet, life applications, integrated interactive systems, etc.

The research directions are general

1.Hardware equipment, including eye trackers, brain wave machines, sensing instruments, evaluation instruments, and equipment that can participate in and assist HCI research and practice.

2.Humanities research, after all, the ultimate goal of HCI is to maximize the good experience of human beings, and all branches and applications are inseparable from the study of users, so the study of users and cultural influences, and even includes some new evolutions and the essence behind the gradual overlapping trend of the triple network (Internet, communication network, and interpersonal network).

3.Another is the design direction, which mainly focuses on the comprehensive user experience design, as well as the specific design of application products and services, as well as the theoretical research on design, the combination with other factors of HCI, the framework system, monitoring and evaluation, process methods, tools and methods, etc.

What are the directions of HCIA? Let's find out.

HCIA certification is divided into many directions, including data communication, security, cloud computing, storage, big data, Internet of Things, artificial intelligence, network unified communication, cloud services, data center infrastructure, intelligent computing, public safety industry, financial industry, SDN operation and maintenance, wireless local area network, and routing and switching.

What books to use to learn HCIATo learn HCIA, see Huawei Switch Study Guide, Huawei Switch Study Guide (2nd Edition), Huawei Router Study Guide, Huawei Router Study Guide (2nd Edition), Huawei VPN Study Guide, Huawei MPL S Technical Pants Friend Key Learning Guide, and Huawei MPLS VPN Study Guide.

Huawei HCIA question types and scoresHCIA certification exam question type for single choice questions, multiple choice questions and judgment questions, the test form is a computer-based test, the language of the exam is Chinese and English, but the default in China is Chinese, the test score is 1000 points, up to 60% of the pass, the answer must be carried out in order, after the exam, the test center will give the results on the spot.

Many friends want to know what is the difference between HCIA and HCIE, let's take a look.

1. The difference between certification levels.

The HCIE certification is an advanced ICT certification and an expert-level certification, and the HCIA certification is a Huawei junior certification and a Huawei certified engineer.

2. The difference in the difficulty of the certification exam.

HCIE certification exam includes pen world hidden excavation test + experiment + interview, the exam is difficult and time-consuming, HCIA certification exam only has one written test, the difficulty of the test is small, you can brush the question bank to pass the test search test.

3. The difference in the gold content of certification.

HCIE certification is an expert-level certification, which is the highest level certification in the ICT field, with a high gold content, and HCIA certification is a junior certification exam with low difficulty, so the certificate is not very valuable, and it can be said that it is just a qualification certificate to enter the IT industry.

HCIE certified gold content

HCIE is the highest level of ICT technology certification in Huawei's certification system, and is one of the most respected and highest-value certificates in the industry.

HCIE Exam Fees

The examination fee for HCIE certification is composed of three aspects: written test, experiment and interview, regardless of the direction, the written test registration fee is 300 US dollars, but the cost of experiment and interview is not unified, of which the experiment plus interview fee in the two directions of operator IP and data center facility design is 1200 US dollars, and the experiment plus exam fee in the remaining direction is 8000 RMB.

HCI stands for Human Capital Index.

The Human Capital Index is a method invented by Watson Wyatt Wordwide, a world-renowned human resources company, to calculate the correlation between human capital and shareholder value. The significance of the human capital index is that if the company's human capital is well managed, the shareholder return will be correspondingly higher.

Since the end of the last century, Wyatt has been tracking the relationship between human capital investment and shareholder returns for 400 listed companies in North America, and found that the human capital investment index is directly proportional to shareholder returns.

Application of the Human Capital Index:

After surveying hundreds of companies in 12 countries and regions including Australia, Singapore, and China, Huaxin Wyatt Company has come to the following conclusions:

1. Superior human resource management is equivalent to good shareholder value. In the Asia-Pacific region, companies with relatively sound human capital management systems can create more than twice as much shareholder value as those with poor human capital systems.

2. Sound human capital management has similarities all over the world. These systems include: a clear and standardized reward and remuneration system and division of rights and responsibilities, the ability to select, recruit and retain talents, and an equal and flexible working environment.

3. Human resources will become a competitive advantage in the Asia-Pacific region. In the Asia-Pacific region, the returns on effective investment in human resources are much higher than in other regions. Having a sound human resources system and efficient human resources functions that meet the company's business needs will enable companies in this region to obtain rich returns.

HCI is a human-computer interaction major. Human-computer interaction (English: Human Computer Interaction or Human Machine Interaction, abbreviated as HCI or HMI) is a study of the interaction between the system and the user.

Systems can be a wide variety of machines, as well as computerized systems and software. A human-computer interface usually refers to the part that is visible to the user. The user communicates with the system through the human-computer interface and operates.

As small as the keys on a radio, as large as a dashboard on an airplane, or in the control room of a power plant. The design of the human-computer interface should include the user's understanding of the system (i.e., the mental model), that is, for the usability or user-friendliness of the system.

Human-computer interaction (HCI) refers to the process of information exchange between humans and computers in a certain way of interaction to complete a certain task using a certain dialogue language. There are a lot of well-known companies and academic institutions that are working on human-computer interaction.

In the history of computer development, little attention has been paid to the ease of use of computers.

Now, many computer users complain that computer manufacturers don't put enough effort into how to make their products "user-friendly." On the other hand, these computer department directors are also complaining, their reasoning is that designing and manufacturing computers is a very complicated job, and the problem of how to apply computers in new fields has already taken up most of their energy, and they really don't have any extra energy to study how to improve the ease of use of computers.

What is the difference between HCIE and HCIA? Let's find out.

1. Different nature: HCIE certification is Huawei certified ICT engineer, and HCIA certification is Huawei certified ICT expert.

2. Different levels of difficulty: HCIE certification exam includes written test + experiment + interview, which is difficult, while HCIA certification exam has only one written test, and the difficulty of the exam is small.

3. Different gold content: HCIE certification is an advanced certification in Huawei's certification system, with a high gold content, while HCIA certification is a primary certification, and the gold content of the certificate is not large.

HCIE application requirements

The registration conditions for the HCIE exam are very relaxed, and there are no requirements for the candidate's academic qualifications, majors, etc., and candidates can directly register for the exam, but the HCIE certification exam is difficult, it is recommended to learn the HCIP certification in the corresponding direction first, and it is recommended that people with more than 5 years of relevant work experience take the exam, but normally speaking, you can also learn from scratch.

HCIE Exam Considerations:

There are many things to pay attention to when taking the HCIE, the main ones are:

1. Candidates need to arrive at the test center 15 minutes in advance, and they are not allowed to be late.

2. Candidates need to provide two valid identity documents, both of which must be original and within the validity period;

3. Candidates are not allowed to bring any personal belongings into the examination room without the permission of the test organizer, including but not limited to backpacks, mobile phones, stools, walkie-talkies, watches, wallets, books, documents, notebooks, notes, papers, etc.
