We propose predictive jumping (PJ), a fast and efficient algorithm that enables user navigation to off-screen targets. The
algorithm is inspired by Delphian Desktop [1] and the off-screen visualization technique–Halo [2]. The Halos represented at
the edge of the viewport help users estimate off-screen target distance and encourage them to make a single fluid mouse movement
toward the target. Halfway through the user’s motion, the system predicts the user’s intended target and quickly moves the
cursor towards that predicted off-screen location. In a pilot study we examine the user’s ability to select off-screen targets
with predictive models based on user’s pointing kinematics for off-screen pointing with Halo. We establish a linear relationship
between peak velocity and target distance for PJ. We then conducted a controlled experiment to evaluate PJ against other Halo-based
techniques, Hop [8] and Pan with Halo. The results of the study highlight the effectiveness of PJ.
