Clinching a business deal depends a lot on a person's presentation skills.But even the best speaker can experience difficulties when using call conferencing services such as screen sharing.The medium is very different from the usual presentation tools and the lack of visual cues adds to the challenge.Utilizing presentations during conference calls has become common practice for many businesses these past few years, as companies have started using the technology to meet with distant clients or coordinate with remote offices.Some conference call services offer screen sharing capabilities which can alleviate the difficulties in conducting presentations.However, there are a few things to understand about the technology to make the process easier and more convenient for users.Screen sharing allows call hosts to their share computer or application screens with other conference call participants.This allows others to see images, charts, and texts on their own screens, which can supplement the information directly being discussed by the speaker.While phone conferencing services have been around for a long time, screen sharing is a relatively new functionality offered by a few conference call providers.Before attempting to use screen sharing, call hosts should check to see if all those participating in the call have compatible systems and install any software required by the system.Depending on the service, screen sharing may work only on specific platforms and devices.Call hosts should also inform all the participants about the optimum screen size for the presentation.This is particularly important if some of the session participants are using handheld devices or ultraportable netbooks with small screens.If users are unable to view the shared screens, it might prevent them from fully viewing the content being shared.One important thing to remember is that screen sharing may show all the items on the presenter's computer.Call hosts should arrange the desktop beforehand, even if the only thing they plan to demonstrate on the screen is a full screen PowerPoint presentation.Having organized folders or desktop items can make it easier to find information needed during the presentation.Lastly, presenters shouldn't use excessive visuals.While voice conferencing services use conventional phone lines for audio clarity, screen sharing will also rely on the viewers' local Internet speeds.A slow Internet connection can cause longer screen loading times and unsynchronized visuals, which can affect the effectiveness of the presentation, and prevent conference call participants from fully understanding the message being delivered.

Audio video conferencing is a shorthand way of describing a virtual conference where no one has to leave her office to meet up with the rest of the group.A virtual conference may use telephones, televisions, computers, conferencing software, collaborative software, file sharing, headsets, the Internet, or any combination of these equipments and tools.Slide presentation, streaming audio, and document sharing are some of the extras you can incorporate into this conferencing method.The ultimate goal is to make the meeting as realistic as possible, where everyone can see each other, hear each other, view and modify projects, and so on - all at a cost that eventually pays for itself in travel savings.The audio video industry has yet to work out all of the kinks.As you can imagine, there can sometimes be technical difficulties in which lines can get torn down in a storm, computers and other equipment can malfunction, and so on.Furthermore, audio video conferencing doesn't work very well for complicated communication techniques, such as those used in closing a sales deal.Audio video conferencing lends a rather impersonal air to meetings, and socializing and bonding don't take place as they would in the real world.You can set up for audio video conferencing in a number of different ways.The older method, still great for a wide variety of teleconferencing purposes, is to have one group in one room, another group in another room (perhaps in another city or country), and have them talk to each other.Each of the two groups utilizes a television, a video camera mounted on the television, a speakerphone, and perhaps some file sharing software for collaboration on computer projects.The newer style is online audio video conferencing, wherein each participant has her very own station in her very own office.This utilizes a computer, the Internet, a web cam, a headset, and file sharing software.This new method allows for even greater ease of planning and attendance, applicability to collaboration, and mobility.You could attend a web conference on the beach while the other attendees are on a train, at home, in a restaurant, or anywhere else.
