Human Factors Model Applied to User Interaction with a Cell Phone
In
this instance, the model depicts information transfer points or
interfaces between a user and a cell phone. The model also
takes into account the environment within which the user-system
interactions take place. Such a model or diagram can be useful
early in system conceptualization and design as a starting point
to determine where, when, and how a user can be expected to interface
with a system. It can be used to begin definition of what
information must be communicated between the user and the system
and how this communication is to be accomplished. For conceptual
purposes, our model is broken down into a "machine-side"
and a "human-side" embedded within an "environment."
The
next 3 pages present the relative strengths of the machine and human
sides of our system.
