Since most of the products around us have turned into interactive digital products, the interaction design has become the most applied design, which makes it the subject of continuous development and revision. The research problem is that there are no controls to regulate the practicing of the interactive design process activities according to teamwork principles. Teamwork principles are the context of the actual work during the practicing of the interaction design process. In addition, the lack of clarity of tasks required from the various disciplines involved during practicing the interactive design process activities. The research aims to emphasize the necessity of practicing the interactive design process activities through the principles of teamwork, and then regulating the role of different disciplines in the stages of the interaction design process. The importance of the research is since it lays down rules for the application of the interaction design process through the principles of teamwork, which facilitates the communication and work of different disciplines together to achieve the desired goals, and it codifies the role of different disciplines in the application of the interaction design program. The research uses the inferential analysis method to analyze information and reach the results. The concept of interaction design, different disciplines related to interaction design, basic activities of the interaction design process and key characteristics of the interactive design process activities were presented. Definitions of teamwork, group thinking, the most important characteristics of teamwork, its principles, and the tasks organized for its application were also presented. The results of the research were reached by affirming the necessity of practicing the interactive design process activities according to teamwork principles. This research defines and regulates the role of the different disciplines at each stage of the interaction design process. That leads the team to work together as a successful multidisciplinary team.The research aims to clarify the role of the interaction design in changing user behavior. By setting some of the basic elements, the interaction designer can direct the user to positive behavior. The importance of the research lies in setting a set of basic elements guiding the interaction designer to take into consideration when designing interactive products to persuade users to change their behavior. These elements can convert undesirable tasks into desirable tasks, or direct user's behavior to positive behavior. The research uses the inferential analysis method to analyze information and reach the results. The concept of the interaction design, its goals, characteristics, and some principles of interaction design and how it affects the user's behavior were presented. Usability, examples for interactive products and how it can change the behavior of users were also presented. The results of the research were that users' behavior could be guided by three basic elements which are the interface appearance of the interactive product, the emotional responses by converting undesirable tasks into desirable and motivating tasks, and the third element is to improve the usability and the way of interaction. These three elements are essential to an interaction designer to take into consideration when designing interactive products.
