Effects of teleconferencing technologies: An exploration of comprehension,feedback, satisfaction and role-related differences

Several theoretical approaches have been put forth to predict and explain the effects of teleconferencing technologies. One approach is to examine the functions of nonverbal signals and to make predictions based on the fact that different teleconferencing technologies allow nonverbal communication to different extents. One of the functions of nonverbal signals is to allow the listener to provide feedback to the speaker in a communication. Prior research has shown that such feedback enhances listener comprehension. In this study, it was hypothesized that different teleconferencing technologies would allow different levels of feedback based on their ability to accommodate nonverbal signals, and this in turn would affect comprehension. An experimental study was conducted to compare comprehension, feedback, and satisfaction in telephone and computer conferencing. The study confirmed that comprehension and speaker satisfaction are related to feedback, but failed to show a relationship between listener satisfaction and feedback. No difference in comprehension, listener, or speaker satisfaction was observed across teleconferencing technologies. Role-related differences were observed between the speaker and the listener. It is suggested that the effects of teleconferencing technologies can be mapped systematically by examining each of the functions of nonverbal signals, one at a time.     

Video teleconference use among geographically dispersed work groups: A field investigation of usage patterns and user preferences

Use of video teleconferencing (VTC) has been on the rise for several years, yet researchers have often discussed the failure of VTCs to support communication. The VTC facility at the MITRE Corporation is used more than would have been predicted by other research. Surveys were mailed to 300 MITRE employees who were known to have used our VTC facility or to have traveled (or both) during August of 1991. The survey asked respondents to describe at least one geographically dispersed work group of which they are a member, and it asked them to discuss how they choose among various approaches to communication, including holding face‐to‐face meetings and VTCs. Respondents felt that VTC is highly useful. It is best used for meetings that have little emotional content or requirements for interpersonal contact. The content of the meeting, however, was not the primary reason given for choosing between travel and VTCs. Cost and inconvenience of travel were cited as reasons for using VTC, and unavailability of VTC was cited as a reason to travel. Results are compared with those of conflicting studies.     

Teleconferencing and its effects on business travel

With escalating travel and convention costs some organizations are looking to teleconferencing by satellite as a possible solution. Although with certain disadvantages over the conventional meeting, it can allow for a maximum of cost-effective information exchange over a geographically disparate area. The author provides an overview of this young industry and discusses what effects teleconferencing will have on business travel.
