MagicDraw: Haptic-Assisted One-Line Drawing with Shared Control

We present MagicDraw, a platform designed for force feedback guidance in one-line drawing. MagicDraw allows users to transition seamlessly between fully assisted sketching and freehand drawing through a control-sharing mechanism. The initial drawing concept is generated based on user input prompts. This platform operates similarly to tracing but introduces two major enhancements. First, MagicDraw provides force feedback guidance, aiding users in maintaining accurate line-following. Second, the system enables dynamic control sharing, allowing users to deviate from the predefined path and engage in creative exploration. We also introduce “exploration region,” where users can perform freehand drawing. In these regions, the predefined path advances outside the boundary, pausing for the user’s creative deviations. As the user returns to fully assisted sketching, these regions shrink until the user resumes force feedback-guided tracing. This approach ensures users can explore creative variations while still receiving structured guidance.
