Pepper's Cone is a simple 3D display that can be built from a tablet computer and a plastic sheet folded into a cone. By rotating the tablet about the y-axis, a user can view 3D objects naturally over 360 degrees without special glasses. The transparent conical surface reflects the image displayed on the 2D screen. The displayed image is pre-distorted, so its reflection appears to be perspective-correct and suspended inside the reflector. Using the tablet's integrated gyroscope, the viewer adjusts the rendered image based on their relative orientation.

Speech is our natural way of communicating. However, it is limited by being a broadcast process: Everyone within a certain area can hear someone else's speech. But what if we'd like to target our speech toward only one person? In this demo, we combine two technologies for realizing targeted communication, with potential applications in task coordination and private conversations. For detecting words, we measure the bioelectric signals produced by facial muscles. Four surface electrodes provide 80-percent accuracy in discriminating between 10 silently mouthed words. For transmitting the message, we use a phased array of ultrasonic emitters, capable of emitting a high-directive sound beam that can be steered electronically without physically moving the array.

|Surface electrodes capture the electric signals produced by the muscles when the user silently mouths a word. A processing unit detects which word was mouthed and reproduces it using the phased array of ultrasonic emitters on the forehead.|

Wind Ceremony represents our desire to capture the unseen. The movement of the installation produces a sound like the blowing wind. When participants pass by, the installation spins like a windmill, inviting them to "become" the wind. The slits in the metal cans in the lower part of the installation produce the wind sound as the installation spins. The upper part of the installation indicates the wind direction. As the participant becomes the wind, indicators point in the direction in which they are heading. Invoking a ceremony of the wind, the two moving parts of the installation make the invisible wind visible.

We are developing a class of robots called situated robots, which hide in plain sight within built environments as furniture and other objects. We anticipate that situated robots will become the universal remote controls of the near future, allowing user interfaces to disappear when not in use.

Tablebot (Tbo) is a situated robot that responds to voice commands, connecting to other objects and the Internet. Tbo's most useful feature is its ability to allow users to interact with others, projecting onto flat surfaces to create telepresence experiences that are less "Skype on a stick" and more embodied and immersive.
