Eyes can draw: A high-fidelity free-eye drawing method with unimodal gaze control

EyeCompass is a novel free-eye drawing system enabling high-fidelity and efficient free-eye drawing through unimodal gaze control, addressing the bottlenecks of gaze-control drawing. EyeCompass helps people to draw using only their eyes, which is of value to people with motor disabilities. Currently, there is no effective gaze-control drawing application due to multiple challenges including involuntary eye movements, conflicts between visuomotor transformation and ocular observation, gaze trajectory control, and inherent eye-tracking errors. EyeCompass addresses this using two initial gaze-control drawing mechanisms: brush damping dynamics and the gaze-oriented method. The user experiments compare the existing gaze-control drawing method and EyeCompass, showing significant improvements in the drawing performance of the mechanisms concerned. The field study conducted with motor-disabled people produced various creative graphics and indicates good usability of the system. Our studies indicate that EyeCompass is a high-fidelity, accurate, feasible free-eye drawing method for creating artistic works via unimodal gaze control.

Automated summary

EyeCompass is a system that enables high-fidelity and efficient free-eye drawing through unimodal gaze control. By addressing the challenges of gaze-control drawing, it provides value to people with motor disabilities. The system utilizes brush damping dynamics and the gaze-oriented method as initial mechanisms to improve the drawing performance, as demonstrated in user experiments and a field study.
