From these previous statements, we could possibly conclude that interiors are all spaces, whether inside or outside. These spaces have physical aspects and visual properties. Materials, furniture, furnishings and equipment that have colors, textures, shapes and forms define the physical conditions. On the other hand, the same spaces have psychological impacts due to their specific layouts, styles, colors and textures, which become places due to their belonging to someone. Therefore, through the particular selection of an interior's components, we, as designers, can affect the users unconsciously, even as they consciously experience these interiors. Whatever the design reflects, it will affect its users positively or negatively, depending on the designers' knowledge, skills and competencies. The wider the designer's experience, the closer the achievement of interior perfection and the better satis-

Interiors—either design, decoration or architecture—represent the space that becomes a place because of its users. It is a creative challenge, which requires innovative solutions to enable people to react positively within it. The potential of interiors is realized in their connections with the design. It is the use of philosophy and concepts to create a unique design proposal. Interiors are sometimes the reflection of the exterior to some extent in many cases. There are no separations, isolation or detachment from the surroundings. A recognized practice is to bring life and activity to the interior spaces and convert them into

The perception and extent of beauty differs from one person to another. Beauty in its purest form is not often widely acknowledged by a mainstream audience due to the diversity of culture and society. However, all creatures found in nature are beautiful to some extent. In analyzing them, we discover that they follow all of the rules associated with beauty. This pleasing relationship starts with the golden ratio in shapes and forms, the impeccable color schemes and the perfect compositions. Any personality or culture admires and evaluates the

It is about each human's cognition and emotion. The feelings of calmness and stabilities occur unconsciously, psychologically, as a reflection of human perceptions, physiology, through the human vision, consciously or unconsciously, physically. The perception of beauty is in the eyes of the beholder as it is a personal experience. It is affected by the lifetime and the influence of trends, evolutionary through time.

Perception is not what we see, smell, touch or hear. Perception occurs when we are aware of what we see, smell, touch or hear. The process of perception starts with the human's physical senses. It then passes through the receptors, based on the person's focus, which enable him to understand what he is facing: a specific picture or environment, definitive odor, precise texture or particular rhythm. It does not require previous experience unless a judgment of the matter is necessary, as to whether it is suitable or unacceptable. Perception occurs when humans consciously receive a particular sensory element. Many theories control the attitude, but most of these theories focus on the visual sense. Concerning interiors, the visual sense is dominant, but the smell, the touch and the hearing senses are also important, as all the senses have an emotional impact [2].

The results received from our perception vary. They could last consciously for a particular time and then become unconscious with continuing effects. The relation between the human experience, cognitional and emotionally, and the level of perception, is relative. The persistence of feelings (consciously) is virtual and relates to some unconscious variations. Happiness, confidence, pleasure, attraction, satisfaction and optimism are positive feelings that result from these perceptions, whereas sadness, uncertainty, insecurity, doubt and even pessimism are some of the negative feelings caused by the perception of the surrounding environment. The interior or the place affects the inhabitants, as they perceive its components. This perception depends on the way these interiors arrange elements to provide positivity. If the users' productivities raise, it means their performance accelerates along with their feelings of aesthetics, that is the reflection of their well-designed environment [3].
