Human – machine interaction

Course description

Human perception and its limitations (human senses, memory and emotions). User interfaces (visual, auditory, tactile, biometrics, natural interfaces). Elements of interaction (models of interaction, hard and soft controls, natural and learned interaction, mental models and metaphors, navigation, context and errors). User centred design of user interface (hierarchical tasks analysis, requirements specification, prototyping). Evaluation of user interface through a user study (methodology, experiment design, independent and dependent variables, objective and subjective evaluations, test subjects, analysis of results).

Course is carried out on study programme

Objectives and competences

The goal of this course is to explain basic functioning of human senses and its’ limitations in perception of various types of information (visual, auditory, tactile). Students will understand various principles of human-machine interaction and gain knowledge on procedures for user interfaces design. They will be able of objectively and subjectively evaluate new or existing user interfaces through user studies. They will be able to analyze and report the results of these studies.

Learning and teaching methods

Lectures with practical demonstrations.

Intended learning outcomes

After successful completion of the course, students should be able to:

  • describe scientific field of humanmachine interaction,
  • explain basic principles of human perception of environment and responses to it,
  • describe available inputoutput technologies of different systems and corresponding limitations,
  • design scientific user study which includes definition of research questions, hypothesis, dependent and independent variables and experimental phases,
  • analyse results of the experiment and conduct corresponding statistical analysis,
  • report on the results in a form of a scientific article.
