</div>It'd also be a great asset to conference calls if we could hear the people<br>
"in the room" each talk from their position. Add stereo microphones and it<br>
is even possible to "look at people" and direct speech more loudly their<br>
way.<br>
<br>
This is more sensational than you can imagine :- I once ate in a restaurant<br>
where the situation of being blind was simulated through absolute darkness.<br>
I was struck by how instinctively the mind registers if someone is looking at<br>
you while speaking, almost as if it has once been useful for our defense or so.<br>
<br>
I think this sensation could make an incredible impact on the concept of a<br>
conference call, and make it come *much* closer to a live conversation.<br></blockquote></div><div><br>Great idea. I did have a look at conference algorithm. It's first added up all mic<br>voice wave and than minus listener's voice from it. By this mean, we could also <br>
increase volume of voice of whom looked at listener and added up before sent the wav to listeners.<br><br>However, the difficult part is how to figure out if someone is looked at someone?<div class="im"><br><br><br><br>
