Lesson
Goals
This
module addresses the capabilities and limitations of human cognition
as they pertain to successful human-centered system design. Prior
modules have covered the human sensory systems: how we obtain information
from our environment and how this information is preliminarily processed.
We will now integrate this information with how the brain further
processes this information into our perception of the world and
enables our interaction with it. Our goal is to maximize human performance
within a system, while developing tasks that neither bore nor overload
human capacity. To this end, this module will cover:
Perception
- Attention and Sensory Processing,
Memory and Learning,
Decision Making,
Cognitive Workload Measurement.
To
design effective human-to-system interfaces, we must understand
the strengths and limitations of human information processing. In
interface design, we are interested in the amount of information
that can be perceived, processed, and acted upon correctly within
a given time frame and how best to present this information for
optimum human performance.
This
module takes about 1 hour to complete.
