Background and Objectives: Merleau-Ponty’s theory, rooted in the embodied nature of human experience, suggests that when humans interact with others or their surroundings, they utilize their senses to form a coherent whole. This idea extends to the theory of multi-sensory perception of the environment by Pallasmaa. Therefore, the quality of the environment and the desire of people to be present in it, along with a set of other factors, is highly dependent on how it is perceived by humans. The success of spaces depends on the frequency of use and the sustained presence of people in that place. In the contemporary era, there is a noticeable decline in the presence of spaces, as indicated by various factors listed in recent research. It is necessary to know the criteria that create and promote presence in spaces, a presence that evokes the meaning and sense of place, in order to enrich the environment and the continuity of the event on an individual and collective scale. In this regard, the current research, relying on the theory of multisensory perception in architecture, tried to show that there is a positive relationship between the multisensory perception of spaces and their presence. At the same time, there is no doubt about the multi-sensory nature of the human perceptual mechanism in the process of interaction with the environment. However, there is not much information about the effect of these sensory perceptions, independently or in combination, on the user’s experience of the environment. The few research conducted in this framework indicate that the emphasis on the centrality of the sense of sight in the creation of spaces, mainly leads to the abandonment of other senses and a deficiency in the coherent sensory perception of the space, which itself, potentially, shows the possibility of reducing the presence of the space for the user.
Methods: In this framework, the current research attempts to answer the question of which sensory stimuli in the environment, whether alone or in combination with each other, contribute to making the environment more present for those who experience it. A test was conducted to quantify the impact of stimulating the senses separately and in combination with the pleasantness of the space as an index of its presence. The subject group comprised 20 volunteers aged between 20 and 35, exhibiting a symmetrical gender distribution, and possessing bachelor’s and higher education levels. Volunteers were placed in a singular architectural space, simulated for them through virtual reality arrangements. They experienced four sensory stimuli (sight, hearing, smell, touch) both separately and in combination. At the same time, the emotional reactions of their brains to these stimuli were extracted and recorded in the form of 6 quantitative indicators, which include engagement, excitement, focus, interest, relaxation and stress, using the Emotiv EPOC+ device and in the Emotiv BCI software environment. Also, the level of pleasantness of the space for them was also recorded, based on their self-report, in a 5-point Likert scale. The resulting data were subjected to qualitative and quantitative analyzes and tests in terms of the possible correlation between sensory stimuli and the pleasantness of the space.
Findings: The findings of the research indicate that in indoor spaces, the presence of visual stimuli such as light, olfactory stimuli such as the smell of plants, and environmental tactile stimuli such as a gentle breeze have an observable effect on the pleasantness of the space and will make people more willing to stay in it. On the other hand, the research results have confidently demonstrated that auditory stimuli in the interior, particularly those with an unknown source and non-aesthetic sounds, are undesirable. However, non-passive vocal stimulation (with sounds of aesthetic quality) may have other results. Summarizing the findings makes it clear that in indoor spaces, the combination of visual, olfactory and tactile stimuli will increase the pleasantness of the space with a high degree of certainty. Also, with the aim of increasing the pleasantness of the space for the user, it is better to control tactile stimulation and minimize auditory stimulation - with an unknown source. 
Conclusion: It is necessary to know the factors that create and increase presence in spaces, a presence that evokes the meaning and sense of place, the degree of prosperity to the environment and continuity in individual and collective characteristics. In this regard, the current research, relying on the multi-sensory theory in architecture, tries to take a positive ratio of spaces and their presence. In general, the research findings suggest that enhancing assimilation in bodily perception and experience of space, such that spatial perceptions are not monosensory, visibly increases the pleasantness of the space. This is likely to contribute to the improvement of presence in the spaces.

Background and Objectives: In recent years, by the transition from premises of structuralism, subjects like the sense of place have been studied in the paradigm of post-structuralism. This has been done through the lens of post-structuralism to better understand the unique characteristics that contribute to this sense. However, it is valuable to understand the importance of comprehending the sense of place, including cognitive processes and analyzing the factors that contribute to this perception. This article challenges the notion that regional features are solely determined by weather and conducts an analytical study in two distinct regions in Iran to examine the impact of regional factors on the sense of place. The sense of place, in general concept, means the different quality of perception of the space through living and being in the space, which can convert a space into a place. The place, with all of its unique features, belongs to a special territory that creates its own region and habitat, which is distinct from other places.
Methods: The objective of this study is to examine how regional factors impact the sense of place. The research focuses on two categories: the natural-geographical environment and the human-made environment. The goal is to identify which regional factors have the greatest influence on the sense of place. This study is a qualitative phenomenological survey that employs an existential (third-person) approach and a comparative analysis method. The study involves field research conducted in the historic districts of Rasht and Yazd cities. According to the research subject, initially, the literature was reviewed, and previous studies were examined. Subsequently, with the aid of field research and an existential approach, the significant factors influencing the sense of place were illustrated in a descriptive manner. Fundamental descriptions of research are extracted in a documentary method and then obtained results are compared with the outcomes of field studies that involve direct observations and interviews with individual or group participants. In fact, the discrepancy in comprehension of humans from a place is the most significant concept of this article, and we can perceive the reasons by recognizing effective factors on comprehension. This research, in a theoretical method, depicts that personal characteristics and environments are pivotal factors in human comprehension. The aim of our study is to compare the impact of regional factors and the built environment on the sense of place. For this purpose, we have chosen two different regions in Iran: Rasht and Yazd. These cities have a rich historical background and are known for their cultural heritage. These cities were selected since they are good examples of places where the sense of place has been preserved over time and is deeply rooted in the collective memory of the local community, according to experts. For compiling the conceptual model of the research, the researchers reviewed the descriptions, concepts, and opinions of experts and researchers and universal experiments on the subject of the sense of place to select the criteria and sub-criterions for this article. According to the opinions of the majority of experts, the sense of place can be identified in three dimensions: somatic place, functional system, and connotation. Considering the holistic concept of the region, which encompasses the habitat and the entirety of a geographical area, including its culture and social values, it is evident that the region influences everything from social norms to cultural practices and habits.
Findings: According to studies of this research, the formation of the sense of place can be identified in three dimensions: somatic, functional, and connotation. Effective somatic characteristics that contribute to the sense of place are derived from spatial constraints and encompass a range of factors, from building and architectural elements to furniture. The second category that can affect the sense of place is the functional system, which is influenced by the residential and urban living requirements as well as social and cultural needs, resulting in different activities and various urban usages. The sense of place can be influenced by these various functions. The third group, referred to as connotation, encompasses both tangible and intangible meanings that interact with the physical surroundings and biological characteristics, as well as normative meanings that are influenced by individual and social values. After that, the research focuses on identifying the most influential factors of the region on the sense of place, which in turn affect the related sub-criteria. These factors include spatial constraints such as horizontal and vertical elements, connectors, openings, and fixed furniture. Furthermore, the region can influence the organization of residential, commercial, collective, cultural, and religious activities, as well as intuitive meanings, and can also affect the tangible features of the place, such as the adaptability of elements to atmospheric conditions, decorative elements, visual background, dominant materials, somatic characteristics of the place, and the scent of natural native elements. The symbolic normative meanings influenced by the region include semiology, tales and fables, inclination towards urban gatherings, the presence and activity of individuals on a daily or occasional basis, accessibility to all age and gender groups, social control, security, and the existence of social and public activities. 
Conclusion: According to a comparative assessment of these factors in the historic district of Rasht and Yazd, it can be stated that the factors of the region that recreate the sense of place have diverse appearances in somatic characteristics, functional systems, and connotations in each of the studied areas. By taking into account the paradigm of this research and examining the elements and sub-components, we can confirm the breadth of the region’s impact on the emergence and understanding of the sense of place in the two factors mentioned earlier, i.e., natural-geographical and human-formed factors.
