A group from the University of Tokyo have developed a method for adding tangibility to holograms using focussed ultrasonic waves -
This project adds tactile feedback to the hovering image in 3D free space. Tactile sensation requires contact with objects, but including a stimulator in the work space dilutes the appearance of holographic images. The Airborne Ultrasound Tactile Display solves this problem by producing tactile sensation on a user's hand without any direct contact and without diluting the quality of the holographic projection.More info from SIGGRAPH '09 and the project's page.
