Just saw these over at MIT’s Technology Review, and thought I’d share…
Touchable Holography:
Researchers at the University of Tokyo have developed a display that lets users “touch” holograms. Virtual objects appear to float in mid-air thanks to an LCD and a concave mirror. The sensation of touching the objects is created using an ultrasound device positioned below the LCD and mirror, creating an area of condensed air.
Augmented Reality Toys:
One student of France’s L’École de Design has developed a way to ‘hack’ toys using AR. His Scope display automatically recognizes ordinary toys that have been mounted onto platforms covered with hexagonal patterns, as seen below. With AR, these hexagons become interactive buttons that are used to make virtual modifications to the toy.

Hyper-Real Virtual Reality:
Another French project, this time from INRIA and Grenoble Universities, could revive the dying science of Virtual Reality. Their new VR system, Virtualization Gate, tracks users’ movements very accurately using multiple cameras, allowing them to interact with virtual objects with never-before-reached realism. This interface demonstrates true physics, as well as crispy graphics, so a cluster of PCs is needed to perform the necessary image capture and 3D modeling.

3D Teleconferencing:
Researchers at the University of Southern California will demo Headspin, a 3D teleconferencing system that maintains eye contact between a three-dimensional head and several participants on the other end of a connection.
To capture an image, a polarized beam-splitter “places” the camera virtually near the eyes of the speaker. The 3D display works by projecting high-speed video onto a rapidly spinning aluminum disk to generate an accurate image for each viewer.

Scratchable Input:
One researcher from Carnegie Mellon University will demonstrate his new scratch input technology. The system turns any surface into an instant input device by sensing the unique sound produced when a fingernail is dragged across it. The interface is small enough to fit into a mobile device (though I have concerns about calibration) and could thereby turn any surface the device is placed upon into an interface.

New Interactive Augmented Reality Experience by T-Immersion
Total Immersion have launched a new kind of interactive attraction using mobility and augmented reality. This new attraction developed in cooperation with Hanwa Co. (Japan) is a state of the art walk through where guests are swept into an experience merging videogame and real live adventure:
Before entering in the attraction, guests are equipped with a backpack and a video gun (with an infrared camera, one LCD display and a trigger). Guests have to use the video gun to progress inside the horror house and find ghosts. As soon as the ghost is found, guests have to shoot it to collect points and succeed their mission.
T-Immersion are using AR really effectively in this instance, in what I think is a quite impressive videogame-like scenario. This is a departure for T-Immersion, who have formerly been focused on installation-based & and webcam-based AR.
Does this give anyone any good ideas for other, more meaningful AR interactions? Let me know in the comments.
