Build next generation apps with eyes and ears using Google Chrome

Treat your users as human!

l UX - 101

l Tools should fit human not the other way around!

Now we have books on UX!

l With computers, we lost 'human touch' in interaction

l Touch screens brought it back, but frankly its not the natural way to do 'things'

Let's get back to basics..

l I have to tell you something.. I will speak and you will listen.l So why it has to be different for computers?!

Enter the new era!

l Now browsers can speak to you.l And browsers can hear you too!

l It's time to listen..

l Yes! That's all we need!
