We present "look-to-talk", a gaze-aware interface for directing a spoken utterance to a software agent in a multiuser collaborative environment. Through a prototype and a Wizard-of-Oz (WOz) experiment, we show that "look-totalk" is indeed a natural alternative to speech and other paradigms. Multimodal user interface, gaze, intelligent environment.
Oh et. al built a gaze-aware interface, "Look-To-Talk," (LTT) that could direct the speech to a software agent in a multi-user collaborative environment REF .
