A Multimodal Interface for Road Design
Alexander Blessing, Tevfik Metin Sezgin, Peter D. Robinson · 2009
Sketch and speech-based interfaces have been suggested for many design tasks. We have investigated the suitability of these modalities for road design, which makes heavy use of two dimensional visual representations. We have implemented a multimodal road design interface that combines sketching and speech. Our system allows designers to specify spatial and geometric aspects of their design using a penbased interface that can recognize user input interactively in real-time. We recognize free-hand drawings of domain shapes, and provide seamless support for gesture-based interaction. We also support speech-based interaction for specifying aspects of the road design that are more naturally conveyed through speech. We evaluated the usability of our system for the task of designing driving courses for the STISIM driving simulator. Our initial evaluation with four users suggests that users find our multimodal interface to be superior to conventional methods.
