Space can be physical; it can be metaphorical. For example: Height is used to indicate more of something (including metaphorically even when no real height or quantity is involved, such as a high temperature or a high note).
Proximity and alignment in 2D are used in computer interfaces to show which options belong together.
Thrones are higher than commoners' seats to show social power.
People in social situations use proximity to show how intimate they want to be with others in the space. Orientation is also used, facing someone or turning away from them.
Large architectural spaces are generally felt to invoke awe, while small ones may be oppressive or cosy, depending on a number of factors.
Using different length lenses (telephoto, wide-angle etc) creates different kinds of perspective: the way scenes are shown alters the viewer's perception.
cognitive map probe
The cognitive map probe. A system with inbuilt sensory devices for the assessment of wayfinding ability. A particularly powerful tool for assessing a person trying to describe their cognitive map of a locality .
Sapir-Whorf
Fully dimensional space is one of the defining characteristics of virtual reality. So far discussion of three-dimensional objects and worlds in virtual reality has tended to look at the technology - what is possible - the application - what is demanded. There is an entire layer missing from the discussion, a layer between the technology and the application, which should deal with the qualities of spatiality itself. The Sapir-Whorf hypothesis - language and culture influence perception itself, would endorse the idea that forms of communication are transformative. In other words, what can be said and thought is influenced by the means selected (or available) for expressing or representing it. The important consequence would be a recognition that virtual realities will themselves facilitate the communication of some kinds of information and experience, and militate against others. Even where there is disagreement with the Sapir-Whorf hypothesis that language and culture influence perception itself, would endorse the idea that forms of communication are transformative.

digital elevation model
Overlaying imagery.animating imagery. Image processing techniques, minimises the clutter of a visually ‘busy’ map with unnecessary and confusing information. Digital elevation models are used for improved terrian visualization. contour, depth. Drawing data onto the terrain model and referencing topographic features are done using algorithms. Creating a heirarchy of data retains most of the desirable information, layering information produces an image of enhanced clarity i.e roads, political boundaries, land use etc.
algoritms and logic Algorithms. Language. If And Or Not When. Examples:
Query: I need information about cats
Boolean logic: OR Search: Any of these words/Can contain the words/Should contain the words
Query: I'm interested in dyslexia in adults.
Boolean logic: AND Search: All of these words/Must contain the words
Query: I'm interested in radiation, but not nuclear radiation.
Boolean logic: NOT Search: Must not contain the words/Should not contain the words
Query: I want to learn about cat behavior.
Boolean logic: OR, AND Search: Combine options as above if the template allows multiple search statements
include void main() { int a,b,c,d; cout <<
Human geography has long studied the processes by which people interact with space, such as mental maps, symbols and icons of landscape, perceptions of the environment, and the everyday use of geography. An emphases within human geography has always been to examine the politics of place and place-making. Experience and identity are part of this, but these exist as natural consequences of the imagination that allows the social construction of places. This notion of “place” is an idea, a mental construct, or a meaning. Thus, it can be imagined and narrated. Place as a social construct is intimately connected to the social construct of identity; geographers with concern for identity often argue that place and identity are simultaneously constructed. Cartesian Dualism. Descartes thinks that the mind and the body are two separate substances that interact causally with one another. 'I think therefore I'am'
“It may be that all human beings have the same perception of space at the biological level of perception. But certainly every society uses its space differently, both technologically and artistically”. J David Bolter 1986 Turing's Man p80
thought : The nature/nurture controversy - Do we perceive space according to universal optical and perceptual principles on which social and environmental conditioning has no effect; or do we acquire some aspects of our perceptual system from external influences?
