Abstract

The present research contributes new empirical research, theory, and prototyping toward developing implicit user-adaptive techniques for system engagement based exclusively on speech amplitude and pen pressure. The results reveal that people will spontaneously adapt their communicative energy level reliably, substantially, and in different modalities to designate and repair an intended interlocutor in a computer-mediated group setting. Furthermore, this sole behavior can be harnessed to achieve system engagement accuracies in the 75-86% range. In short, there was a high level of correct system engagement based exclusively on implicit cues in users' energy level during communication.
