Pull-Ups: Enhancing Suspension Activities in Virtual Reality with Body-Scale Kinesthetic Force ...
summary
Pull-Ups is a ceiling suspension kit that replaces TRX straps with pneumatic artificial muscles and load sensors to pull users up to 15 cm actuation, driven by proportional valves and Arduino control. A JND study (Weber constant ≈2) defines light and strong feedback levels from pressure–displacement profiles up to 700 kPa. A within-subject user study shows passive suspension reduces motion sickness versus no feedback, while strong active feedback significantly increases reported realism and enjoyment.
