Web conferencing began with chatting and instant messenger services, and it slowly grew to accommodate visual communication with audio support with the introduction of the webcam. This handy and affordable device allowed Internet connected users to view and chat with the person or persons that came online for the net meeting, regardless of their location.
With more improvements in the shape and features of web cams and other videoconferencing systems that enabled visual communication and interactivity, there has been no stopping this technology. This number continues to grow and expand with the invention of new and more interactive features being added to the peripherals by the manufacturers every year.
The development of telemedicine has proved helpful for patients in need of urgent and emergency medical care and guidance. The field of telemedicine and telenursing makes use of special peripherals, such as microscopes fitted with digital cameras, called videoendoscopes and medical ultrasound imaging devices, called otoscopes that are extensively and effectively used in conjunction with VTC equipment to transmit data about a patient. This makes for instant communication that is both visually precise and has audio support as well, giving a clear description of a medical condition.
Another medical application using videoconferencing is video interpretation. Video interpretation allows patients and medical personnel to communicate accurately, quickly and exactly when they are needed. Visual contact with an interpreter ensures comprehension and eliminates the ambiguity often associated with a voice-only interpretation. Deaf and hard of hearing patients can have instant access to sign language interpretation without the cost of an on-site interpreter.
