This review is based on the context of how to perceive the visualisation in a space. To understand the relationship of human perception and their interaction in the environment in the level of neurology. The purpose is to build up the part of visualisation for the summer project in the rational level.
1. Human perception of eyes movement
Cutsuridis (2008) pointed out in the article Neural Accumulator Models of Decision Making in Eye Movements that humans and animals are constantly obtaining a guide from both external and internal cues from a variety of possibility when they interact with environment, which established the neural models of decision making influencing their behaviour.
Decision making, in fact, is applied in a wide areas, from cognitive and behavioural neuroscience to artificial intelligence, and it also involves in the fields of economics, sociology, statistics, computer science and ethology. (Cutsuridis 2008)
He discussed eye movements are the important part to understand decision making in the level of neurology, as eye movements must be constantly capturing potential visual targets as the next end-point to get link with the previous one. Meanwhile, referring to Brain Anatomy and physiology in the later section of this article in terms of visual information from two distinct pathways of eyes.
It can be seen that human’s decision making based on the potential visual change of the environment through neurological character, which is to capture the different/vivid/fresh/unfamiliar object in the space. This review helps to build up the concept of environmental real-time visualisation by the way of vivid form to make the positive interaction between audiences and the environment.
2. Consciousness and Unconsciousness
Chalmers (year unknown) distinguished ‘easy’ and ‘hard’ problems of consciousness, and questioned consciousness in the level of objective and subjective experience through brain mechanism of cognitive system. He concluded that visual sensations we are experiencing can be called consciousness.
Although, the consciousness concept cannot be defined easily in one or two words, since it is multiple concept based on the individuals and the context of what we are experiencing in different background. As Franco (2008, p286) said ‘The consciousness concept is hybrid, connoting a number of different concepts and phenomena.‘, consciousness is closely linked to multi-layers’ cognitive base. He also pointed out that consciousness and attention cannot be separated, in fact, the study of visual consciousness helps us to understand ‘consciousness’, which involves in the relationship of consciousness and the unconscious of attentional mechanisms.
This part of review inspired me to present the contrast form of chaos and well-organised during participants are experiencing, observing and receiving the feedback of sound and visualisation in the space.
3. Cognitive Neuropsychology/ Behavioral Neuroscience
Goldstein (2011) used ‘ball case’ to refer the viewpoint of distributed processing in the brain. More specifically, if a person is perceiving a rolling red ball, he / she just see the object without thinking its colour, shape, location, and how it moves. However, the brain with a wide distribution of activity has already done to deal with the message behind the phenomena, and the cognitive process, including memory, language, making decisions and problem solving, is distributed and work together in the brain. (Goldstein 2011, p37)
This is the interesting part as a reference in the context of review of neural cognition, which impels me to think about the setting of object (loudspeaker and microphone) as dynamic for this project – if it could be achievable after doing the further experiment.
4. Spatial Perception
‘Our environment does not simply consist of multiple objects, but multiple objects which exist in definable spatial interrelationships. It is only when relatively precise spatial information is being used that we are even aware of thinking ‘spatially’.’. (McCarthy 1990, p73)
Spatial processing, as the highly complex activity in the context of cognitive function of brain, could help us understand how human convert their perception in different status, as well as how to establish the relationship between people and the environment. McCarthy (1990) gave an example of patients with cerebral lesions in investigations of spatial processing, which was documented that the most active perception of patients was in the visual area of brain. Moreover, in terms of cognitive function of spatial perception, she also clarified that the theoretical account could involve in the issues of spatial representations and the interrelationships.
It can be considered that people perceive the spatial information based on the objects that our eyes capture in the environment, and how the brain define the status by consciousness and unconsciousness linked with our knowledge base and experience. The visual field domains the highly important part in terms of perceive the position precisely. However, it could be assumed that people perceive their position and establish the relationship with the space more easily in the 3D dynamic immersive condition, as being part of the environment.
