ABSTRACT
This article presents a set of adaptive reset techniques for use with haptic retargeting systems focusing on interaction with hybrid virtual reality interfaces that align with a physical interface. Haptic retargeting between changing physical and virtual targets requires a reset where the physical and virtual hand positions are re-aligned. We present a modified Point technique to guide the user in the direction of their next interaction such that the remaining distance to the target is minimized upon completion of the reset. This, along with techniques drawn from existing work are further modified to consider the angular and translational gain of each redirection and identify the optimal position for the reset to take place. When the angular and translational gain is within an acceptable range, the reset can be entirely omitted. This enables continuous retargeting between targets removing interruptions from a sequence of retargeted interactions. These techniques were evaluated in a user study which showed that adaptive reset techniques can provide a significant decrease in task completion time, travel distance, and the number of user errors.
