5:55 PM -- There's a lot of confusion over what exactly telepresence is. Is it really anything more than just a buzzword? The most common answer you get from a telepresence vendor is that unlike video conferencing, it makes you feel like you're in the same room as the other person and forget that there's technology involved. But isn't this a rather subjective definition?
Cisco, while discussing its latest efforts in telepresence, offered a few hard numbers to start the conversation. (See Cisco Rolls Out TP.) Here're a few things that should be a requirement for defining something as being immersive enough to call telepresence:
The resolution must be at least 1080 pixels
The images must be life sized, which means a 65-inch screen
The voice quality must be realistic, which means spacial audio
It's not the be-all and end-all definition, but it seems like a good place to start.
