N2 - This study proposes a gesture based CAD interface that uses pose, position, velocity and direction of fingers as input data in order to draw, extrude, scale, translate and rotate an object in the 3D space. The system allows the user to generate basic geometrical primitives and advanced geometries (geometries that cannot be realized using the CSG primitives) and to perform basic CAD operations described above. As opposed to traditional systems wherein path based gestures are used to carry out operations, the proposed system uses switches that operate on simple binary principles thus reducing the computational cost of the system by eliminating the use of a classifier scheme to a high extent. A user study involving 10 subjects is also presented in order to determine the qualitative and quantitative efficacy of the proposed system.
