Hapbeat: single DOF wide range wearable haptic display

Hapbeat is a single DOF haptic display, which enhances virtual reality experiences and music listening. It consists of two coreless motors and stiff string, and feedbacks compression forces of 0 to 600 Hz, i.e. from DC forces to high fidelity acoustic vibrations. The motors generate vibrations of up to 600Hz and the string transmits them. Comparing to existing devices, Hapbeat can generate powerful low frequency vibrations and transmit them to wide range of the user's body in spite of its compact body. The user can feel air pressures of powerful low frequency sounds, high fidelity vibrations of acoustic instruments and hitting of strong smashes.
