HCSketch

Sketch input user interfaces for 3D geometric modelling software aim to convert 2D sketches into 3D models to provide simple, efficient shape input methods. However, in general 2D sketches portraying objects naturally provide insufficient information to create unique 3D models. Hence, various additional assumptions have to be made, which nevertheless do not always produce the expected result. Human computation is an approach where tasks that are difficult to perform by a computer are instead executed by humans, usually over the Internet, often in a game setting. This project aims to utilise this approach for sketch input and collect and analyse data of how humans interpret sketches to enhance and evaluate sketch input software.
