ISYS2056 Lecture Notes - Lecture 6: Interactive Computing, Usability, Eye Tracking
Document Summary
Discipline concerned with the design, evaluation and implementation of interactive computing systems for human use. With the study of major phenomena surrounding them. How fast can a user learn to use an interface sufficiently well to accomplish basic tasks. Measuring the increased proficiency reached by users completing tasks. If a user has used the system at some earlier date. Casual users can return to the system after some period without much relearning. Built-in methods of reducing the need to remember. Once an experienced user has learned to use the system, how fast can he or she accomplish tasks. One can measure how much faster that user can complete a task. How often do users make errors while using the system. How easy is it to recover from a user error. An error is any action which inhibits the accomplishing of a desired goal. One can measure the error rate, the number of errors occur while performing a task.
