What is a junior criminal technical assistant? What are the job responsibilities?

What is a junior criminal technical assistant? What are the job responsibilities? Strictly speaking, this statement is incorrect. My judgment should be to ask questions about criminal technical titles. The junior title is assistant engineer. For example: trace inspection assistant engineer, file inspection assistant engineer, etc. Job responsibilities are mainly responsible for on-site investigation, physical evidence inspection and basic inspection and appraisal. The sequence of professional titles can be roughly divided into junior (assistant engineer), intermediate (engineer) and senior (senior engineer).

What are the responsibilities of the interface design assistant? It refers to the overall design of human-computer interaction, operation logic and beautiful interface of software. Good UI design not only makes the software personalized and tasteful, but also makes the operation of the software comfortable, simple and free, which fully reflects the positioning and characteristics of the software. UI is actually the abbreviation of user interface, which means user interface. Wikipedia defines UI as follows: User interface is a system in which people (users) interact with machines. The user interface includes hardware (physical). And software (logic) components. Generally speaking, the goal of human-computer interaction engineering is to produce a user interface, which makes it easy, effective and pleasant to operate the machine and produces the expected results. This usually means that the operator needs to provide the least input to achieve the desired output, and it also means that the machine minimizes the uncertain output to people. User interface is a man-machine interaction system, including hardware (physical layer) and software (logical layer). Generally speaking, the goal of human-computer interaction engineering is to create a simple and convenient operation interface for users. So in other words, UI refers not to simple users and interfaces, but to the interaction between users and interfaces. Then, as a UI designer, what you need to do is not only to design a beautiful interface, but also to design an interface that makes users comfortable and easy to operate. According to the traditional classification, web technology is divided into two parts: design and development, which are called web design and web development in English. Since the UI designer is called design, it definitely belongs to design, and design is generally divided into front-end design and back-end design. The front-end is called front-end and the back-end is called back-end. For a simple analogy, the front end is responsible for drawing blueprints, the back end is responsible for building tall buildings, and the UI designer belongs to the front end design. I think these two explanations are incomplete now. As a UI designer, you can't be limited to front-end design. This doesn't mean that you only design the appearance of the building, not Gai Lou, or even Gai Lou. You must always monitor it. Imagine that your great design is out of shape because of a bad construction team. You can only blame the poor supervision, not the construction team. Of course, the premise is that you have the right to find a capable construction team. You should also understand the task of finding a construction team. If you only speak out and splash ink, regardless of the feelings of the construction team, you will also become the target of public criticism. For example, if you design a gorgeous interface or human-computer interaction function, and the result goes bankrupt because the technology can't be realized, then you can only say that you are ignorant and don't consider reality. Let's take a look at the responsibilities of UI designers: Source: Offidea Design UI design studio should follow a routine Internet product project process: 1. Make MRD (market demand document) and market demand document. After obtaining the approval of the project initiating department, the product needs to be realized first, and the market and competitors need to be analyzed in more detail, which functions are used to achieve business objectives, which functional/non-functional requirements are divided, and the priority of functions is needed. In practical work, the possible outputs of PD at this stage include Mind Manager's mind map, Excel's feature list and so on. 2. Formulate PRD (Product Requirements Document). Product requirements document. As soon as the progress is refined, this part is written by PM the most, that is, demand analysis in the traditional sense. We mainly refer to UC (use case) files here. The main contents include: the specific description of function usage (generally useful examples of each UC, actors, preconditions, postconditions, UI description, process/sub-process/branch process, etc. ), function point business process, interface description, demo, etc. produced by Visio. For Demo, it may be simply drawn with dreamweaver, ps or even sketchpad, and sometimes UI/UE will support the production of high-fidelity demo, and develop the kind that can be used directly in the future. 3. User analysis report collects relevant data, analyzes the use characteristics, emotions, habits, minds and needs of target users, and puts forward user research reports and usability design suggestions. This part of the work can also be done in cooperation with the team. When time and project requirements permit, real-life user analysis can be carried out. 4. Product architecture design involves a lot of interface interaction and process design. According to the results of usability analysis, the interaction mode, operation and jump process, structure, layout, information and other elements are formulated. The above is what UI designers need to follow up. It's really your task to start from here. 5. Product prototype design is to make a lot of typesetting and layout of page modules and elements, deepen them, and add some interactive elements to make them more concrete, vivid and vivid. I'm sorry, I have to add here. The process design of the whole system is also the UI designer's. To this end, you should often browse a large number of websites, personally experience and accumulate classic, friendly and cordial system processes, and you should consider any final link of the whole system. This is the biggest and most difficult part of the UI designer. For example, the user registration process, where to go after success, where to go after failure, how many processes there are after success, and what objects each process contains. . . Wait, wait, wait. 6. Interface UI design If you are very inclined to graphical interface design, here is your favorite part. But you must combine the analysis results discussed in the circle to design, otherwise your work will be difficult to convince. Tone, style, interface, window, icon and panel are the key points of this link. 7. Interface output is mainly coded by page engineers and front-end programmers. I'm going to show up again: sorry, as a UI designer, the basic works that can best meet your design are of course from your own hands. To do this, you should know how to crop pictures and make static pages. Then all kinds of special effects SHTML, style sheets, JS code to achieve your great design, can you not do it yourself, but you must have a standardized design, and your construction team must operate in full accordance with the specifications under your training and leadership? Oh, look, you should be the UI manager here. 8. Analyze user reports and make perfect adjustments. It involves many departments, including usability cycle research, user experience feedback and test feedback. At the same time, UI personnel should also improve some feasible suggestions. Many designers don't like to change things, which is a big taboo. I add a 9. SEO optimization design of the whole project. . Don't look at others, yours. But as far as many companies are concerned, what they get from UI designers is a VISO diagram without any explanation, which gives many UI designers an illusion that I only need to make renderings and ignore other links, resulting in the design of product interface based on personal preferences because of insufficient information, but it is not competitive at all when facing users. I think UI designers should join the project from the beginning, including understanding market positioning, profit model, competitors and so on. By analyzing competitors' user interfaces, UI designers can be given a preliminary graphic concept. By participating in user surveys, user analysis can obtain user characteristics, age, needs, preferences and other information. , which can be used for style positioning. Grasping plays a vital role. Knowing the product structure, you will know what functions should be done and what functions should be highlighted. After participating in the above work, I believe many UI designers are confident in the products they want to design. Later, by analyzing user reports, user feedback and other information, the interface was adjusted to make a perfect product put on the market, and this product is no longer entirely based on the personal preferences of UI designers. Remember! So what kind of ability do you need as a UI designer? UI design is divided into three directions in terms of work content. It is mainly determined by three factors of UI research, namely, research tools, the relationship between researchers and interfaces, and researchers. Research Interface-Graphic UI Designer At present, most UI workers in China are engaged in this industry. Some people call him an artist, but in fact he is not an artist in a simple sense, but a product form designer of software products. Most of these designers graduated from art colleges, and most of them have artistic design education background, such as industrial appearance design, decoration design, information multimedia design and so on. Study the relationship between human and interface-interaction designer, interaction designer. Before the graphical interface appeared, UI designers were always called interaction designers. The job of the interaction designer is to design the operation flow, tree structure, structure and operation specification (spec) of the software. What a software product needs to do before coding is interactive design, establishing interactive model and specification. Interaction designers are generally software engineers with backgrounds. Researcher-User Testing/Research Engineer Any product needs to be tested in order to ensure the quality, the coding of software needs to be tested, and the natural UI design also needs to be tested. This test has nothing to do with coding, but mainly tests the rationality of interactive design and the aesthetics of graphic design. The testing method generally adopts focus group, and measures the rationality of UI design in the form of target user questionnaire. This position is very important. Without this position, the quality of UI design can only be judged by the experience of designers or the aesthetics of leaders, which will bring serious risks to enterprises. User research engineers are generally psychologists, and their literary background is more appropriate. To sum up, UI designers are: software graphic designers, interaction designers and user research engineers. The real meaning of this position: ui designer is by no means an artist (or just doing "beautification" work), but a technical position rather than an artistic position. If we examine the competency model of a ui designer, then he should have four dimensions of competence: 1, communication and document writing skills. If ui is the bridge and link between man and machine, then ui designer is the bridge and link between software designer and end user. If the ui designer can't have good communication and understanding skills, and can't write excellent guiding principles and norms, then he can't show his dual values to developers and customers, and he can't finish his work. Here I want to add a reading comprehension ability. 2. Excellent technical ability: You don't have to write java, but you absolutely have to know what java is and what it can achieve. Even if you can't write code, you must at least "realize". For example, if you want to make a grid control component, first of all, you should know exactly what data formats there are and how to store them: you can get data through mark, json objects or arrays, xml or even strings. Secondly, you need to know which is more suitable for the current environment, the server-side implementation or the client-side implementation. These all depend on skilled and experienced ui designers, while ui designers who don't know technology can neither make reasonable designs nor communicate effectively with developers. In a word, ui designers should at least be proficient in the mainstream development technology of the presentation layer (if they are doing web presentation layer, they generally need to be proficient in css, javascript, xml technology, and even jsp and java should reach the working layer), and have sufficient understanding of the mainstream design patterns, technical routes and open source frameworks in the market. It can be said that ui designers should strive to be "presentation layer architects" in terms of technical quality and ability. (that's a good speech. Applause. Many artists get down at this point. I hope everyone will not get down. 3. Graphic design ability and prototype development: The most important work for a ui designer in his life should be graphic and prototype design. So, let's talk about what prototype design is first. Prototype method is a common means in iterative development and design stage, and prototype design should run through three stages: requirement, general design and detailed design. The purpose of developing a prototype is to turn the design into an "interface language" that users can understand, and at the same time, it also plays a certain guiding role for developers (even as part of development). The value of user interface prototype lies in that it can help software designers find the defects in each stage of design as early as possible, solve these potential problems before development, and greatly reduce the risk and cost of software development. This is essentially different from the traditional waterfall development. At present, most domestic companies still adopt waterfall development mode and put ui design in the later stage of development. This not only makes ui designers unable to give full play to their strengths, but also makes up for it by "beautifying", and also makes the developed products often have fatal design defects, which can not meet the needs of customers. Therefore, the "art designer" in the company is the result of backward and imperfect software development methods, not the "art designer" or ui designer itself. Let's talk about graphic design ability. In fact, ui designer is just a general term. Within the ui design industry, it can be roughly divided into the following roles: usability and interaction designer, visual planner, user experience researcher, graphical user interface designer, etc. The commonly understood ui designer is actually a gui designer (such as rokey of China, who is an excellent gui designer and currently works for Microsoft). The main job of gui designers is visual positioning and creation. The following chapters will introduce the responsibilities and daily work of gui designers in detail. If the ui designer does not have excellent graphic creation ability, then he can't express the beauty in his mind at all, and "communication" is out of the question. Graphic design ability is the most basic ability of every ui designer at the beginning. It is also the part that can best measure the ability level of a ui designer. Welcome friends of the ladder. Com engaged in network planning and operation industry to exchange and discuss. 4. Anthropological theory and cognitive psychology: Although this concept is a bit big, it is an area that every ui designer should strive to explore all his life after his career is stable. It can be said that the essence of design is "people". To be a people-oriented interface, it is natural to understand people and their behaviors. For example, you can't design an interface that displays two important tips at the same time in different positions on the same interface-because people can only have one focus at the same time, which is determined by physiology, not someone's subjective assumption. For another example, why does windows find its previous shadow more or less every time it is upgraded? You might say that this is the design style of Microsoft. No, it's not a style, but a habit. It used to be a habit of Microsoft. Now, you use windows, so you have this habit. Which operating system is better, Apple or Microsoft? The answer is anything you like. Yes, what a simple truth-like, like is a habit, how can you be sure that the design you think is "correct" is exactly what people like? Here you can mention the styles of extjs and ext a little. In short, it is the traditional interactive style (wmip) of desktop applications. What is the style of the web page? If you ask me, I prefer the internet to be an open magazine and a hot spot to show designers' talents (bugs continue to applaud you). Why do you say that? Because of the uncertainty and openness of the network. In my experience, webui design is the most difficult and restrictive in all software ui design fields (these restrictions are often uncertain). Even if an excellent webui designer turns to desktop ui design or mobile device interface design, it is relatively easy to succeed. Therefore, as a webui designer, it is understandable to reject the desktop ui style, which stems from his habit and his "liking". 5. I continue to add: Have high-level aesthetic ability, spatial thinking ability, logical ability and certain literary accomplishment, keep a young heart, don't fall into the mode of digging your own grave, and your creativity will never be exhausted. Wow, UI designers are gods. . . . Don't be afraid, time will accumulate all the knowledge you need for you, as long as you can stick to it. At this point, you should probably understand the inner meaning of the names ui design and ui designer. On the issue of "art design", I should have my own conclusion, so I won't explain it any more. Another digression: ui designer is a relatively senior technical position in the position system of the company where I am currently working, equivalent to a senior software engineer, and needs more than 3 years of industry experience to be competent; Senior ui designers and software designers are at the same level, and their upper-level positions are architects. This is very different from the "artists" recruited by some companies. Wow, I guess you can't watch it anymore. The road to becoming a god is long and full of danger. If you are not careful, you will give up halfway. Then give you some confidence and look at the prospects of domestic UI designers. At present, domestic UI design is still a relatively unfamiliar word in China. Even Rococo design is constantly exploring the needs of customers and users on the road of UI design. We often see some job advertisements that say: interface artist, interface art designer and so on. This shows that the understanding of UI in China is still in the aspect of art design, and the work of UI is only to draw lines and strokes, lacking the understanding of the importance of user interaction. On the other hand, in the process of software development, there is still a phenomenon of attaching importance to technology and neglecting application. Many merchants think that the core of software products is technology, and UI is only an aid, which can be reflected in the proportion and treatment of personnel. However, this is not the real value embodiment of UI design, but an inevitable process for the development of UI design. Let us take the mobile phone industry as an example. When mobile phones first entered the market, they were not only prohibitively expensive, but also had no other functions except talking. Because technology was the dominant technology at that time, everyone paid attention to the signal, standby time, life and so on, and paid little attention to the shape and rationality of the product. Time has passed, and the current technology has fully met the needs of users. Therefore, in order to create selling points and improve competitiveness, businesses attach great importance to product design, and also frequently launch short messages, color screens, harmonious short messages, multimedia messages, cameras and so on. In this way, the beauty, individuality, ease of use, easy learning and humanization of the product have become the selling points of the product. The development of software products and material products is the same. In the past, due to the limitation of computer hardware, coding design became synonymous with software development, and the beautiful and friendly graphical interface and reasonable and easy-to-use interaction mode were not paid enough attention. In fact, the software of this period is called software program, not software product. Nowadays, with the rapid development of computer hardware, the past software programs can no longer meet the requirements of users. In the fierce market competition, it is not enough for software products to have powerful functions, and it is not enough to defeat powerful opponents. Fortunately, some far-sighted national enterprises in China have begun to realize the huge selling points that UI brings to software products, such as Kingsoft's movie tyrants, word tyrants, drug tyrants and Internet logos. Due to the emphasis on UI development and status, Jinshan products are second to none among similar software products. The UI department of Lenovo Software actively carried out user research and usability testing, combined ease of use and aesthetics, and launched successful UI examples such as dual-mode computers and happiness series, which won Lenovo the title of the third consumer PC in the world, and so on. Practice has proved that as long as merchants invest little in the beautiful and easy-to-use design of products, they will have great output. Its input-output ratio is far greater than the input of function-led development. We have to admit that there is a considerable gap between China and western developed countries in many fields at this stage. How to catch up with them is the historical mission of our generation. The field of software products is not limited by technology and materials like material products, and the core problem of software products is people. Improving the personal ability of software UI designers and reducing the personnel gap is the first key issue in the development of UI in China. At present, there is no relatively sound UI design major in domestic universities, so the key to improve the ability of UI designers lies in providing a good resource environment for learning and communication. There are many communication design websites in China, which introduce industrial design, graphic design, fashion design, painting art, multimedia flash and so on. However, UI design has not received due attention, and it is only placed in the column of digital design or graphic web design. This unique resource is not enough to train excellent designers. It is necessary to have a place with fast information, rich resources, first-class design level and professional authority to learn and exchange UI design to meet the needs of growing UI designers. The future is boundless, right? People who can succeed are considered as talents. March forward for our greater ideal. . . We are pioneers in UI-related logs:

China, the "poorest" country in the world, is embarrassed by its per capita GDP.
