Development of user oriented mobile CAD interface

Mobile 3D printing application should cover object manipulating functions with its service oriented properties and users. The users can be considered not only experts but also novices. Thus, it is necessary to provide design guidelines for natural user interfaces of the CAD applications. This paper suggests a guideline for designing interface of mobile CAD application based on existing works on general interfaces of mobile devices. With contribution to mobile interface studies, it is expected that the guideline can provide practical rules for designers.
