Aerial interaction with femtosecond laser induced plasma

In this article we report case studies on the aerial interaction with laser induced plasma as computational voxels. Laser induced plasma of air can be utilized to generate light source or tactile components for aerial interactions. In current studies we transformed ordinary air into interactive visual media [Ochiai et al. 2016b] and haptic media [Ochiai et al. 2016a]. To implement these interactive media, we employed Computer Generated Hologram and rendered with laser induced plasma generated by femtosecond laser sources with Spatial Light Modulators and ultrasound generated by acoustic phased array. In article, we introduce the concept through these studies and results of our research group in aerial touch display project called Fairy Lights in Femtoseconds [Ochiai et al. 2016b].
