MAGIC (Manual and Gaze Input Cascaded) pointing methods use eye gaze as a complementary input for the primary input device. This paper introduces a novel MAGIC pointing technique to provide fast and accurate selection. Cursor sensitivity is reduced near eye focus to allow fine selection, and increased away from target to improve selection speed. MAGIC-SENSE is tested against a traditional mouse and a gaze only pointing method using an ISO 9241-9 compliant circular Fitts' Law experiment. Using MAGIC-SENSE, subjects achieved lower error rates without compromising movement times compared to mouse-only method. A local calibration method that can boost all MAGIC pointing techniques is discussed.
