1. Wind-Blaster

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.

Seungwoo Je, Hyelip Lee, Myung Jin Kim, Minkyeong Lee, Yoonji Kim, Youngkyung Choi, and Andrea Bianchi, MAKinteract Lab → [e-mail] 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).
