What is Periscope?
Periscope is a live broadcast service that combines the best of video and instant messaging. The “scoper” or presenter broadcasts live while the viewers instant message the scoper and other viewers. It is like Skype except only only one person is on screen. And It is like a instant messaging chatroom while everyone is watching the same thing or person. It is also like everyone can now have their own live television channel with a Twitter feed on screen (so you can see why Twitter purchased it).
What is different about Periscope?
Periscope’s format is different in three ways to similar services or what had been attempted before. Firstly, open skype-style chatrooms (which Skype did try once and failed dismally) would make it impossible to tell who is talking and who the main speaker is. It would be (or was) like a cacophony of yelling voices at a cocktail party with no one as host. Secondly, live video allows scopers to interact immediately with viewers and other viewers as well, which video blogging on YouTube does not. This is done without distraction to the scoper by separating video and instant messaging between scoper and viewer. Lastly, Everything is instant. Video blogging is instant. Interaction with viewers is instant. Viewer reactions are instant. Gratification for both scoper and viewer are instant. And once you have your gratification you can move on and do other things. It is truly taking the best of all worlds of Skype, YouTube, chat and vlogging.
What is the potential of Periscope for teaching?
Given its instant nature, scoper/viewer interactiveness and visualness it has great potential as a teaching tool. I could do a live class where other students can join in and ask questions. There is no waiting between question and feedback. And as I said earlier it is like having one’s own television channel with a live twitter feed going at once. The videos then can be saved and even uploaded by you to YouTube or others to katch.me.
