VirtuaMouse One-Hand 1.0
the author of this app says:
VirtuaMouse One-Hand helps to increase your productivity by freeing your "stylus hand" to do more important things. It gives you a virtual mouse pointer that can be used instead of the stylus, anytime that the stylus isn't convenient for you.
The virtual mouse cursor can be easily controlled with the D-Pad/Joypad. You can use this cursor as a "temporary stylus" whenever you need it, instead of relying on the stylus for those applications that aren't very "thumb-friendly."
VirtuaMouse One-Hand helps you to use your device (with one hand) whenever you're doing something that needs a free hand, like when taking a phone call, drinking a cup of coffee, or when you already have something in your other hand.
It's not meant to be a full stylus replacement; instead, it's meant to give you another choice: either use the stylus, or don't -- now it's up to you!
* Reduces stylus usage and increases productivity * Easy and natural to use * Makes almost any program more thumb-friendly * An effective stylus alternative, so that you can use your Pocket PC anytime -- even without a stylus. * Quick access via Hardware Button(s)
