The human life style in community spaces and deficiency in the number of appropriate spaces for the presence and gathering of people, indicates the need to creat necessary infrastructure in order to reconcile people with public realms. This is a key requirement for the continuance of human social life and improvement of their social culture. Public (community) spaces are places that belong to all the citizens and acquire meaning only with presence of people and their activities. Therefore, creating different capacities such as liveliness and its improvement - as one of the key factors in this area - is necessary  to make human presence more possible. The principle issue in this paper is to desig a suitable lively place for improving the level of ideal social interactions with the help of  liveliness factors. For this purpose, we will analyze and categorize effective factors in the improvement of liveliness in spaces such as variety¸ memorability¸ flexibility¸ readability, while presenting the views of professionals and experts of this field. This paper is carried out with the help of survey research method and the use of questionnaires. Also, liveliness factors have been evaluated by experts and professionals in two categories; physical and mental factors of public spaces. The result of this paper shows that the effect of mental factors on people s presence and liveliness of the public space are highly significant than the physical factors; Focusing on components such as liveliness in design, identifying and providing cultural and social needs of users, and considering these factors in the design of the complex, shows a meaningful connection with enhancement in the acceptance of these public spaces and of people s presence in them. This is due to the fact that joy and vitality of a space encourages the reappearance of people, and this creates hope in life and can have a positive effect on their personality development in this environment.
