Best practices for Graphical User Interfaces design with interaction based on head movements

Resumo

The availability of various interaction devices is a reality that expands the potential of user interface design. Traditional keyboard and mouse duet are replaced for new ways of input that use user's body as a means of interaction. However, Graphical User Interfaces (GUI) are still the major output when we analyze the form of display and feedback directed to the user. Therefore, it is necessary to rethink the design of the interaction when the devices used exploit other users' abilities in order to stimulate a better experience of using these devices when in conjunction with an IGU. In this context, the objective of this paper is to propose best practices for IGU projects that use interaction based on head movement tracking. We used the results of a Systematic Review of the Literature and a practical experiment trying to compare efficiency, effectiveness, user experience and interaction characteristics.
