We present a chat system that uses animated text associated with emotional information to show the affective state of the user. The system obtains the affective state of a chat user from a physiological sensor attached to the user’s body. This paper describes preliminary experiments and provides examples of possible applications of our chat system. Observations from informal experiments compari...

BACKGROUND Murine and human ventricular cardiomyocytes rich in acetylcholine (Ach) receptors are poorly innervated by the vagus, compared with whole ventricular innervation by the adrenergic nerve. However, vagal nerve stimulation produces a favorable outcome even in the murine heart, despite relatively low ventricular cholinergic nerve density. Such a mismatch and missing link suggest the exis...

When multiple conversations occur simultaneously, a listener must decide which conversation each utterance is part of in order to interpret and respond to it appropriately. We refer to this task as disentanglement. We present a corpus of Internet Relay Chat dialogue in which the various conversations have been manually disentangled, and evaluate annotator reliability. We propose a graph-based c...

This document specifies an application-level protocol (i.e., payload type) for chat tools using the Real Time Protocol for Distributed Interactive Media (RTP/I). RTP/I defines a standardized framing for the transmission of application data and provides protocol mechanisms that are universally needed for the class of distributed interactive media. A chat tool provides an instant messaging servic...

We describe initial work on extensions to word highlighting for multiparticipant chat to aid users in finding messages of interest, especially during times of high traffic in chat rooms. We have annotated a corpus of chat messages from a technical chat domain (Ubuntu’s technical support), indicating whether they are related to Ubuntu’s new desktop environment Unity. We also created an unsupervi...

Synchronous chat rooms have been used to support students’ collaborative learning. However, little work has empirically studied its relationship with students’ sense of community and furthermore the role of personality in affecting students’ chat room behavior. In this paper, we report results of a user experiment (with 489 students). We find that students who have actively used chat room posse...
