A paper posted on arXiv proposes Sketch Bug, an interface that replaces traditional mouse-and-keyboard debugging controls with sketch-like pen input. The idea is to let programmers draw directly on their code to interact with the debugger, rather than navigating menus or typing commands.
The authors describe how lightweight marks can set breakpoints, while symbolic strokes handle execution control. This could reduce context switching and make the debugging process more intuitive, especially on touch-enabled devices.
The abstract is brief, so details on implementation and evaluation are not yet available. Still, the concept points toward a more natural, gesture-driven approach to a task that has remained largely keyboard-centric for decades.
