I'm in video conferences for several hours per week. Many of the far end points have auto tracking cameras, either Polycom's Eagle Eye Director or Producer or Cisco's Speaker Track. If you've ever been in a meeting with one these that are active on the other end, you'll know it immediately.
You'll know them because:
- The camera moves around, sometimes without reason
- The camera takes 3-4 seconds to pan over to whoever is talking (and by that time, they may be done talking)
- You start waiting for it to move - and that's completely distracting.
Imagine if you're in an important meeting and you start sneezing. Guess what, you end up on camera front and center so everyone can see you sneeze. Well, actually since the delay is so long, they get to see you wipe your nose instead. Great, isn't it? This technology assumes that only one person is ever going to speak at a time. The problem is, meetings aren't like that. Meetings aren't just one person in site A talking to one person at site B. They are dynamic with sometimes several people speaking at once.
Not to mention that most people who have them tell me they turn them off because they simply "don't work".
It's best to see actual demonstrations of the products versus marketing videos. These two videos speak for themselves.
Notice the length of time it takes to switch. The people who stopped talking look a little lost.
