The interface is essential for any software system and is an integral part of it, focused primarily on the end-user. It is through the interface that the user judges the application as a whole; moreover, the user often makes the decision to use an application based on how convenient and understandable the user interface is. At the same time, the complexity of the design and hire front end developer of the interface is quite large. According to experts, on average, it is more than half of the project implementation time. Relevant is the reduction of costs for the development and maintenance of software systems or hire front-end developers or the development of effective software tools, where efficiency is understood as the ease of development, ease of maintenance, and ease of use of the program.
One of the ways to reduce the cost of developing and maintaining software systems is the presence in the toolkit of fourth-generation tools that allow you to describe (specify) the created software tool at a high level and then automatically generate executable code according to the specification. The software market offers a wide range of tools for its development. However, the available tools support the development of only some of the components of the user by means of the fourth generation, the rest of its components are programmed by the developer, which significantly increases the costs, development, and maintenance complexity.
Dedicated interface development tools simplify user development by prompting the developer to specify user components using specification languages.
Ways to specify the interface
There are several main ways to specify the interface.
-Linguistic, when special languages are used to set the interface syntax (declarative, object-oriented, event languages, etc.).
-A graphical specification is concerned with defining an interface, typically by visual programming, programming demonstrations, and by example. This way supports a limited class of interfaces.
-An interface specification based on an object-oriented approach is related to a principle called direct manipulation. Its main property is the interaction of the user with individual objects, and not with the entire system as a whole. Typical components used for manipulating objects and control functions are handlers, menus, dialog zones, buttons of various kinds
-Specification of the interface according to the specification of the application. Here the interface is created automatically according to the specification of the semantics of the application. However, the complexity of describing the interface makes it difficult to soon emerge systems that implement this approach.
Thus, the user interface includes:
- basic message system (system of concepts of the subject area);
- system of messages for the user;
- message system for the application program;
- means of ensuring the convenience and comfort of the user;
- means of intellectual support of the user;
- controls for user-interface interaction.
How to become a user interface developer
Front end app development is a mixture of design and programming, which is a pretty good option for a creative programmer. When I first got into programming, I didn’t even know that jobs like UI Developer even existed.
Another frustration that is often found among UI developers is that they are hired from companies that have few design resources. This can mean that you are the sole proponent of design in your organization, and your voice can be easily drowned out. Perseverance is often required, otherwise, you can get frustrated very quickly with a poor user interface and frustrated with your coworkers.
