When mobile or tablet design is executed well, the device feels like the extension of our bodies. Because interfaces respond even before we consciously give them a command.
Often, the interface “dissolves in behavior” and we feel empowered, as though the device we hold in our hand is the equivalent of Iron Man’s suit of cybernetic armor, or Batman’s utility belt.
I call this empowering experience a “Magic Moment”.
Most importantly, these “Magic Moments” make people fall in love with your app, show it to their friends, telling, nay, insisting they download the app and experience the magic for themselves. These are the moments we designers live for.
And mobile and tablet devices are more suited to creating and fostering “magic moments” than any other device.
