The Bristol Interaction and Graphics group has been exploring various technical solutions to create displays that use air as the diffuser and haptic interfaces that use air pressure for tactile feedback. For example, we generate fog-filled bubbles that can be tracked and projected on to provide ambient notifications. Similarly, we create a curtain of mist to act as a reach-through personal space between the user and an interactive tabletop.  In this talk, I will present some of our recent projects on this topic and conclude with UltraHaptics haptic feedback system that allows users to experience tactile feedback simultaneously in multiple locations on an interactive surface. This feedback is created in mid-air – so users don’t have to touch or hold any device to experience it.
