Prototyping for Tiny Fingers.

The technique of building prototypes on paper and testing them with real users is called low-fidelity prototyping or "lo-fi" for short. The value of prototyping is widely recognized, but value is not always gained in practice. Lo-fi prototyping, which requires little more in the way of implementation skills than the ones learned in kindergarten. Paper prototyping is potentially a breakthrough idea for organizations that have never tried it, since it allows to demonstrate the behavior of an interface very early in development, and test designs with real users. If quality is partially a function of the number of iterations and refinements a design undergoes before it hits the street, lo-fi prototyping is a technique that can dramatically increase quality. It is fast, it brings results early in development and allows a team to try far more ideas than they could with high-fidelity prototypes. For years software developers have used everything from demo-builders to multimedia tools to high-level languages to build prototypes.
