VideoconferencingPractical Considerations
Audio
85 per cent of the information disseminated in a video conference is delivered aurally, so getting the audio right is a high priority.
• Consider the choice of room
• Switch off any heaters or air-conditioning systems
• The room should be as undisturbed as possible by external noise
• Know how to MUTE your system
VideoconferencingPractical Considerations
Lighting
It is not normally necessary to bring in specialist lighting. In practice, if a room is to be used regularly, it is better to cut out natural lighting and use artificial lighting, over which you have control.
Lighting should fall on the faces of those taking part in the conference to give a good picture to the far-end.
Don't sit in front of a window - this will produce good silhouettes but will mask the detail of faces.
Turn off any computer screens that are in view.
Avoid cluttered backgrounds. A single-colour background, perhaps with a sign or logo to identify the school, is better than lots of pictures, work or posters.
VideoconferencingPractical Considerations
Room Layout
Ensure that all those taking part are in the camera shot.
Ensure that those speaking can be clearly identified.If numbers involved are small, aim for a 'head and shoulders' shot of the participants.
If numbers are large, it may be necessary to move those contributing nearer to the camera and microphone for parts of the conference - however, aim to keep movement to a minimum.
Ensure that all those taking part can see the screen.
The camera should be positioned close above or below the screen and presenters should look directly at the camera so it appears to those watching at the far-end that they are looking directly at them.
