Sim-U-Sketch: a sketch-based interface for SimuLink

Abstract

Sim-U-Sketch is an experimental sketch-based interface we developed for Matlab®'s Simulink® software package. With this tool, users can construct functional Simulink models simply by drawing sketches on a computer screen. To support iterative design, Sim-U-Sketch allows users to interact with their sketches in real time to modify existing objects and add new ones. The system is equipped with a domain-independent, trainable symbol recognizer that can learn new symbols from single prototype examples. This makes our system easily extensible and customizable to new domains and unique drawing styles.
