User experience mprovement
Audio is a crucial factor in the success of a meeting by videoconference. Its quality must be assured with specialized video and audio equipment in a way that the participants may be able to speak fluently and easily.
The equipment must be disposed in a non-obtrusive and functional way, adding an almost transparent interaction way during a well-planned AG session. The microphones must be placed in strategic points allowing a better capture of the sound and the positioning of cameras near the projection screen in order to create the illusion of visual contact.
The video must be of such a quality that natural communication is produced. Those present are thus more polite and less inclined to key in their laptops and other discourtesies if someone can clearly see them. Rising hands and passing turns become something natural.
Distributed PowerPoint, desktop sharing, OpenGL and MPEG video offer wide contents to users.
