Pj. Klutke et al., Practical evaluation of standard-based low-cost video conferencing in telemedicine and epidemiological applications, MED INF IN, 24(2), 1999, pp. 135-145
The results of the evaluation of use of low-cost video conferencing systems
(VCSs) in telemedicine is presented. Application sharing, a new feature of
these systems, recently has allowed high-quality computer-supported collab
orative work (CSCW). The video conferencing (VCing) equipment used was Inte
l(TM) ProShare 200(TM) v2.0a. It is representative of other low-cost VCSs.
The areas of application are epidemiology and telemedicine (orthopaedics an
d radiology). Potential end users filled out 58 evaluation questionnaires c
oncerning user profiles, contents and benefits of the sessions, organizatio
nal aspects, user friendliness, user acceptance, cost effectiveness, techni
cal and multipoint related aspects. Although the end users had a lot of com
puter experience, their knowledge in VCSs was rather limited. The users ass
essed the system capable of being integrated into routine work, despite a h
igh organizational impact. The VCS is user friendly, application sharing be
ing used in almost every session. Audio quality was not always sufficient.
The remote video was sufficient, as was the quality of medical images such
as CT, MRI or X-ray. The user acceptance of the system was high. Multipoint
sessions require a structured protocol to be effective. Some technical pro
blems with MCUs (Multipoint Control Units) occurred. The use of low-cost st
andard VCSs in telemedicine is advisable and is a good substitute for real
meetings.
