MULTI TOUCH SCREEN

3D modelling tools are for experts: this is the common perception among people. Traditionally the mapping of the 3D interaction in a virtual world to the 2D interaction on a monitor is done via mouse and keyboard input. Ideally, interacting with a virtual 3D object should be intuitive, mapping closely to the actions for the physical equivalent, for example shaping clay or folding paper.

The objective of this project is to use multi-touch to increase the efficacy of 3D model interactions. We selected origami as the context because it is relatively simple to model, yet provides many interaction opportunities. Furthermore because most people have some paper-folding skills evaluations are not limited to experts. Although this project was conducted on origami, which is relatively simple, we believe the result can be applied to more complex areas, such as engineering or architectural design.

Demonstration of the software's functionality can be found here.
