Tellart's 2008 Research and Development annual demonstrations. This third chapter demonstrates the NADA Mobile hardware and software toolkit by Tellart. The hardware involves a custom designed circuit board that communicates to a computer via a wireless radio link. The board allows for both sensors (light, heat, motion, force, etc.) and actuators (lights, motors, etc.) to be integrated with the iPhone/iPod Touch's hardware and software. The goal for Tellart in making NADA Mobile was not to extend the functionality of the iPhone as much as to create a sketching a prototyping platform that would empower designers to quickly and easily imagine and test new concepts for interactive products and services.
