Theoretical+Concepts

This is a list of theoretical concepts that will help us research and design our device:

__Computer Visualization:__ Having a 3D illustration could show the different surfaces and layers as oppose to a 2 dimensional drawing. This 3D illustration will aid viewers to visualize the products outline and dimensions, it is the best method to make the product visual to client and therefore helpful for communicating and making decisions.

__Gestalt Laws of Pattern Perception:__ According to Gestalt psychology, “the whole is different than the sum of its parts.” There are rules that illustrate the way we see patterns in visual displays, the rules will allow for viewers to understand our design through the use of the 8 Gestalt principles which are: Figure and Ground; The idea that in perceiving a visual field, some objects take a prominent role (the figures) while others recede into the background (the ground). Proximity; Objects near each other tend to be grouped together. Similarity; Similar elements tend to be grouped together such as elements of similar colors, shapes and texture. Grouping can occur in both visual and auditory stimuli. Continuity and Connectedness; Points that are connected by straight or curving lines are seen in a way that follows the smoothest path. Rather than seeing separate lines and angles, lines are seen as belonging together. Symmetry; The idea that when we perceive objects we tend to perceive them as symmetrical shapes that form around their centre. Most objects can be divided in two more or less symmetrical halves. Closure; Objects that are grouped together tend to be seen as a whole, we tend to ignore the gaps and complete contour lines. Relative Size; Different sizes can be designed. Motion Perception-Common fate; Elements with the same moving direction are perceived as a collective or unit.

__The 3-stage Model of Perceptual Processing:__ Parallel Processing: Information is processed in parallel to extract basic features of the environment. Pattern Perception: Active processes of pattern perception pull out structures and segment the visual scenes into regions of color, texture and motion patterns. Sequential-goal directed processing: Information is reduced to few objects held in visual working memory by active mechanism of attention to form the basis of visual thinking.

__Texture:__ The dispenser will be made of thick, rubber allowing simple attachment and removal.

__Color:__ Our design will consist of different colorized textures to appeal to children, teenagers, and of people of different ages.

__Economic:__ Our design is an insight of designing a cheap purell/hand sanitizer dispenser that would save money, space and minimize the infections that can result from a handshake, a hug or any physical contact.

__Ergonomics:__ It is the science of designing the job, equipment, and workplace to fit the worker. Appropriate ergonomic design is required to avoid recurring strain injuries, which can expand over time and which can lead to long-term disability. By designing the dispenser, ergonomics is a main factor that we will base the design on and keep in mind. Simply, a machine working seamlessly with man almost as if it is an extension of one self.
