Abstract

We present intelligent magnification techniques that combine distortion techniques with automatic content information awareness. They have been developed to support sketching on small displays. A first evaluation study that tested and compared three existing distortion lenses showed their general unsuitability for sketching. Based on these findings we developed and evaluated a new set of intelligent lenses, which use context information as the distortion regulator. The evaluation shows that using our new intelligent lenses leads to fewer errors, without time penalties, and with higher user satisfaction.
