I'm getting the impression that he holds his phone in one hand (left) and uses the other hand to use the touchscreen (right).

Tablets running Windows get the added functionality of using the touchscreen for mouse input, hand writing recognition, and gesture support.

He also stated that the game uses the touchscreen in several ways through the game.

There are no dial buttons on the iPhone; all calls are made by using the touchscreen.

The game stars a 3D Pac-Man as the user rolls him throughout the playing field using the touchscreen.

The game allows the player to play using the touchscreen, and the long, repeat and repeat long notes will not appear in this mode.

The game allows the player to play using the touchscreen exclusively, or both the touchscreen and rear pad.

Both use the touchscreen, while the latter uses the microphone as well.

I used the touchscreen and the keyboard and saved the note on the screen to disc using Sam's badge number as a file name.

Using the touchscreen, the owner can play with, train, pet, walk, brush, and wash a virtual dog.
