Abstract:

Introduction:
The term exhibition has many meanings and interpretations that affect the design concept and its diversity. It can be used in many spaces and areas, especially in projects of interior design exhibitions.
The exhibition meanings are summed up in how to arrange and coordinate the display themes and the components of the interior design elements in an organized and exciting manner to attract the users of the interior space. The desired functional purpose is achieved by raising the efficiency of the interior spaces in a way that makes it easy for the user to craft efficiently whether the purpose of the exhibition is educational, commercial, or a trade show at an international exhibition. However, the exhibition should display the shows consistently with the display's diversity and achieve the psychological message needed for each type. This exhibition strategy is applicable to trade shows, temporary exhibitions, museums, and international trade fairs.

Objective:
The research aims to clarify the meanings and the different psychological messages that must be followed in the different presentation methods but for the same object or goods (for example, apple company products), which corresponds to the difference in the subject, whether an educational museum display, a commercial display, or an international exhibition. Thus, the goal is to guide the student to design and create concept ideas according to each type of display to achieve a successful exhibition display. Moreover, selecting suitable materials, colors, and display units in terms of scale, shape and form, circulation type, lighting, and graphic design should be appropriate to the exhibition design.

Methodology:
The research methodology follows the comparative and applied approach to all interpretations and definitions of the meanings of the interior design project exhibition. An analytic approach will introduce them to the student and emphasize a reasonable and realistic understanding according to the job and the psychological message needed for each type of project; educational, commercial activities, and international trade shows. Results and recommendations will help the student and, later on, the designer defines the exhibition's concept, which helps in the success of any exhibition interior design project.

Conclusion:
The research problem lies in the inconsistency of many unclear meanings and interpretations of the exhibition style terminology used in the various interior design exhibition projects. The different functional goals of the exhibition design, commercial merchandise exhibition, educational museum exhibition, or promotional display in international trade exhibitions could create confusion and misapprehension. As a result, it affects the idea of designing the project and achieving the desired goal within the interior spaces. The project's failure resulted from a confused and unclear understanding of the different psychological messages of display and the various display units' designs. This paper highlights the different aspects of each type, along with appropriate psychological messages that enhance the users' experience and help the exhibition designer deal with such interiors and guide the interior design students in the exhibition design course.
