Instead of having the old sliding window off to the right or the left in presentation or online meeting software I when I have little avatars and they waved and they moved and they jump up and down when they want attention when the user on the other end of the avatar wants attention and little chat bubbles pop up over them when they talk?
This would help change the paradigm from text to visual and make it more like you're speaking to a crowd. And it would also lay the groundwork for augmented reality where you could put on glasses or even virtual reality and the meat in a virtual room or in a physical room with augmented reality and see people spread out around you is there avatars and be able to click and call on them and wave at him and do things just like in the real world.
Probably already out there but needs to be developed and advertised and as the technology grows and becomes more accepted used more and more toward becomes the default.
