a change in paradigm
The software was conceived to assist or enhance the first 2D drawings steps in the design process by using both hands to draw organic, non parametric, surfaces. This method produces rough 3D sketches that can be refined latter using any 3D modeling software package. The focus of this project is on the input interface. The goal is the development and testing of an easy and natural 3D two hands interface. This system is more natural to work with than using the mouse, less difficult than learning complex software packages and less abstract than manipulating two dimensional entities on orthogonal projections it is, in essence, a 3D modelling system directed to free hand sketching in a mixed reality environment.
In conclusion this work argues that 3D design, based on free hand form generation, allows for an enhancement of the traditional creative process through spontaneous and immediate translation of a concept into 3D digita shape.
It will be a digital model that has had one less stage of translation where possibly some of the spontaneity of the creative process would be lost.

this project has achieved:
a. non-intrusive, spontaneous 3D digital design
b. simple, low-cost Interfaces based on non intrusive devices
c. real world applications: concept design
d. shape generation

future directions
i. infra-red cameras
ii. infra-red tracking
iii. plug in for 3D CAD applications
iv. adding graphic primitives and viewing capabilities
v. extending towards an AR configuration
