Video figure for "JumpMod: Haptic Backpack that Modifies Users’ Perceived Jump." This work was presented at the ACM CHI 2023 conference in Hamburg, Germany by Romain Nith. This work was done in collaboration with Jacob Serfaty, Sam Shatzkin, Alan Shen and Pedro Lopes at the University of Chicago's Human Computer Integration Lab.
Abstract: Vertical force-feedback is extremely rare in mainstream interactive
experiences. This happens because existing haptic devices capable
of sufficiently strong forces that would modify a user’s jump require
grounding (e.g., motion platforms or pulleys) or cumbersome actuators
(e.g., large propellers attached or held by the user). To enable
interactive experiences to feature jump-based haptics without sacrificing
wearability, we propose JumpMod, an untethered backpack
that modifies one’s sense of jumping. JumpMod achieves this by
moving a weight up/down along the user’s back, which modifies
perceived jump momentum—creating accelerated & decelerated
jump sensations. In our second study, we empirically found that our device can render five effects: jump higher, land harder/softer,
pulled higher/lower. Based on these, we designed four jumping
experiences for VR & sports. Finally, in our third study, we found
that participants preferred wearing our device in an interactive
context, such as one of our jump-based VR applications.
