We discuss a model for this process and show that, currently, it is heavily skewed toward the look aspect. This could prove to be a problem when designing highly interactive natural user interfaces, which put a stronger emphasis on the feel of an application. In order to thoroughly analyze this gap we compare eight current prototyping tools, by using a multi-touch application scenario. From this evaluation we derive requirements for a tool more suited towards multi-touch prototyping.enmulti-touchprototypinginteractiondesignmuc: langbeitrag (vorträge)
