Expression constraints in multimodal human-computer interaction
Sandrine Robbe-Reiter, Noëlle Carbonell, Pierre Dauchy · 2000
Thanks to recent scientific advances, it is now possible to design multimodal interfaces allowing the use of speech and gestures on a touchscreen. However, present speech recognizers and natural language interpreters cannot yet process spontaneous speech accurately. These limitations make it necessary to impose constraints on users' speech inputs. Thus, ergonomic studies are needed to provide user interface designers with efficient guidelines for the definition of usable speech constraints.
