A Generic Operation Concept for an Ergonomic Speech MMI under Fixed Constraints in the Automotive Environment
Gregor McGlaun, Frank Althoff, Holly Ruhl, M. Alger · 2001
In this contribution we focus on the evaluation of a generic operation concept for a speech-based MMI integrated in a car radio and mp3-player. The system is additionally subject to several restrictive economical and geometrical boundary conditions. Nevertheless, the interface has to meet high technical requirements: its handling must be easy to learn, comfortable and, above all, intuitive. In several trial series, two competing generic dialogue concepts (Tree Structure Principle vs. Action-Object Principle) are evaluated. Moreover, designing the layout of the limited display user distraction effects are studied. As a general result, we obtained 88 % of the test subjects to be very satisfied with the operation comfort of the final system. 1.
