Interaction with the environment, and objects
within it, requires the control of movements of the body (action).
In many cases these body movements in turn are used to control
the behaviour of devices, tools, or vehicles. Perceptual processes
provide information about what actions can be performed and provide
the information required to control action.
This subject discusses the perceptual processes
in four sections, each with supporting readings and examples.
In Perceiving Layout
the sources of information used to perceive the layout of surfaces
and objects within the environment are examined.
Control of Self-Motion discusses the ways in which information is used to
control self-motion, and how such information might be obtained.
Perceiving Events deals with how information specifies events and how
observers selectively attend to the cues specifying events.
Perceiving Affordances addresses the issue of how observers perceive the
opportunities for action afforded to them by the environment
and objects within it, and the implications of this for the design
of objects and environments.
The assessment for the subject is an Assignment
in which students choose a task, determine the information required
to achieve this task, document the perceptual processes by which
the required information may be obtained, and assess the implications
of this analysis.
Details of the required readings, other references
and additional resources are provided in the References
section.
