Carrying on with the BlackBerry Jam keynote presentation videos, here is Don Lindsay, RIM's Vice President, User Experience Design. Don takes us through a bit of history behind BlackBerry Peek and Flow, explaining how they came to create these new designs for BlackBerry 10. Peek allows you to just pull aside the task you're working on (the app you're using) to see your notifications, then reverse the motion to go right back into what you're doing, hence the Flow. Showing off a few examples, Don really helps you get a feel for the new design elements and how they will help BlackBerry users be more productive and time efficient.
