Ungrounded haptic force feedback is a key element to achieving an
immersive experience in virtual reality (VR). Mobility is a crucial part of
the experience, especially for applications such as first-person VR games.
Wind-Blaster is a novel wearable interface that generates force feedback by
spinning two propellers mounted on a person’s wrist. The device is interfaced with a game
running in Unity. By manipulating the direction, duration, and intensity of the feedback on
the wrist, it is capable of rendering different haptic stimuli mapped to four weapons.

In this issue’s Demo Hour we bring technology
and nature closer together. Fog, rain, wind—each of
these projects have their own way of integrating “the
weather.” These designs use weather elements as an
interaction medium (Receipt of Memory), as sensory
input (s Weather and RainSeason), and even
as an actuator ( Wind-Blaster).
