Abstract:
Aerial haptic feedback is a popular topic in research fields on real- world-oriented interaction, augmented reality (AR), and virtual reality (VR). Various methods such as magnetic force, ultrasound, and air vortices have been proposed for this purpose.
Aerial haptic display has several advantages: it projects a force from a distance without physical contact or wearable devices, and it has high programmability. In other words, it can be set and rearranged at an arbitrary position in a 3D space because it does not require physical actuators.
In the this study, we seek to research new aerial interactions. We aim to develop a new aerial haptics system to express a wide range of feedback. The proposed system (Figure 1) combines aerodynamic and acoustic fields. We use the aerodynamic vortex [Sodhi et al. 2013]from the aerodynamic field, and the focused ultrasound [Hoshi et al. 2010] from the acoustic field to develop this device.
