**3.1 About design in general**

When someone is asked what design is, simple definition might be that the design is related to the achievement of objectives within the constraints. This definition does not say everything about the design, but it helps users to focus on the following elements:


It is impossible to accomplish all of the user's objectives within constraints, but in life, everything is a matter of compromise, even in such cases. The best designs are created in areas where the designer understands the compromises and the factors affecting them.

The most important part of interaction design or interactivity is user. It is necessary to set up a user in the first place and to keep the user in the central place [3, 6, 8].

create a colorful and real interaction.

Here is a brief overview of the simplified view of the four major phases focused

• **Requirements.** The first phase is based on definitions of needed requirements. Before phase one, it is necessary to know what is currently happening. For example, how do people watch movies? What kind of personnel is currently

• **Analysis.** The results of observations and interviews should be delivered so that the key issues can be removed from them for the later stages of design. Usually, this is about the scenarios, the stories about the interaction, which may be combined with a task analysis or be independently recorded in order to

• **Design.** There is a central phase when it starts from "what is desired" to "how to do it." There are a number of rules, guidelines, and principles of design,

• **Repetitions (iterations) and prototyping.** People are complex and cannot be expected to reach the right design immediately. That is the reason why the design should be evaluated in order to be seen how it works and where it could

• **Implementation and deployment.** Finally, when it comes to the stage when the design is rated as well as done, then it should be created and applied. This includes the development of appropriate elements, writing documentation,

One man cannot read and look at all the required techniques. Time is limited and there is no link between the period of design and quality of the final design. This means that a design should be accepted as final, even if it is not perfect; it is often better to have a product which is acceptable, is done on time, and costs less than to have one that has perfect interaction but was not done on time and was over a budget. For example, if a user encounters a system that appears to be perfect, one can be pretty sure that it is a poorly designed system; the system is poorly designed, not because the design is bad but because a lot of effort has been spent for the design
