I have recently invented several multimodal extensions for HMDs. Proof-of-concept prototypes of mid-air tactile feedback for a mid-air fogscreen (Sand et al. 2015) and for an HMD ((Sand et al. 2015) enable to touch and feel synthetic 3D objects while interacting with them. A super-wide FOV optical design for HMDs (Rakkolainen et al. 2016; Rakkolainen et al. 2017) can cover even the full human FOV. Recently we have significantly extended the FOV of a standard VR viewer (Rakkolainen et al. 2017). We also invented a visual feedback system for HMDs, which surpasses the eye and its lens, sending light directly to retina (Koskinen et al. 2017), PTZ superzoom + 360° camera, and illumination for 360° cameras.

We have also refined the previous gestural AR/VR interface (Rakkolainen 2003) with new UI concepts together with the University of California, Santa Barbara (UCSB). They enable embedded VR viewing and easy use of 3D UIs for smartphones (Rakkolainen et al. 2016).
In 2020 we published a Survey of Mid-Air Ultrasound Haptics and Its Applications
