Summary:
Goal - To provide a simple 3D computer aided tool for the direct transfer of design intent into a corresponding computer respresentation.
Guidelines for immersive control - hide the mathematical complexity of object representations, direct and real time interaction, full scale modeling, large working volume and intuitive, easy-to-learn.
Related work - "3 - draw" uses HMD, tablet and 2 hand interaction. The system keeps track of the 2 hands with one hand controlling the tablet and the other drawing in the tablet. and some 2D - 3D drawing tools.
Features - Drawing, creating curve network, new curve in the network, filling the surface , Curve smoothening, Curve dragging, surface sculpting. UI - the design tools spread as virtual pointers at the end of pen. This allows smooth selection than grabbing.
Forceful feedback might help in improving the system in giving feedback about constraints.
Discussion:
An user study to understand the user experience would have helped. The tool selection widget is interesting and different. By including the force feedback, there might be some advantages but it must not be invasive and hinder in the activities of the user. The kind of implementation of the force feedback would make a big difference in user experience.

Any user study would have helped. I was disappointed with the lack of information about the hardware they used.
ReplyDeleteI think the user study was very limited. I wished they would've used a professional in addition to the artist.
