...AR MultiPendulum allows users to interact with virtual objects directly with their hand instead of tapping an object's location on a touchscreen. It brings a mesmerizing multi-pendulum simulation into augmented reality. Users interact with this simulation through hand movements and modify it through a holographic interface. Not only does this app bring augmented reality to a pendulum simulation, it is also the first app to simulate more than three pendulums. Additionally, by repurposing a VR headset for AR, this is the first app that gives users an affordable AR headset experience.
