Communication is the key to everything. From the time you wake up and and press a button on your coffee-machine to tell you to make you a coffee, to when you talk to your other half to make plans for a night out, a trip or your own wedding. Imagine a world where each time when you wanted to do your grocery shopping, you first had to stop at the bank to make sure the funds were clear. Or whenever you wanted to drive from home to work you had to first stop at a petrol station to check whether your car had enough petrol to make the journey. In this talk I will show you some common scenarios where we are currently doing just that with our websites or mobile apps and not even thinking about it. We will then look at some ways we can avoid that and bring context back onto our applications.
