ELEC 499 Group #9

2011

 
 

The product enables video tracking of speakers in a conference room setting. The current speaker's direction is determined by audio triangulation using an array of two or three microphones. Both audio and video are sent though USB to a computer and then on through a network connection to the other end of the conference call.


The following design objectives were followed throughout the completion of this project
•Low Cost
•Portable and User Friendly
•Easily Deployed from Room to Room
•Cross-Platform
•Usable with most VOIP clients like Skype
