Presently, information devices such as cell phones, PDA's (Personal Digital Assistance), and electronic organizers have been changing drastically. Multifunctionality is increasing, sizes have been reduced, and popularity continues to grow. Therefore, usability is becoming important. It has been effective to improve the usability to run the usability testing in the early stages of product development. In usability testing, various prototypes have been made and used. However, in developing prototypes there have always been several problems. For example, a functional prototype is expensive and takes a long time to produce. On the other hand, a design prototype is cheap, but it does not have any functions. In this paper, we propose a method that can create a functional prototype that reduces production time and cost. Furthermore, the functional prototype incorporates input operations and has the ability to record input data. This is done by first creating a quick and cheap model using stereolithography. Then a small camera is inserted to implement user interface functions such as buttons. With this, real time motion images can be processed and recorded.
