Hand-held device projects images that respond to the real world

from NewScientist:

The device – called Twinkle – projects animated graphics that respond to patterns, shapes or colours on a surface, or even 3D objects such as your hand.

It uses a camera to track relevant elements – say a line drawn on a wall – in the scene illuminated by the projector and an accelerometer ensures it can sense the projector’s rapid motion and position.

Video: Touchscreen wall explores gigapixel photos

from Singularity Hub:

Students at the University of Tromso in Norway have built an amazing multitouch wall with a mind-blowing 7168×3072 resolution – 22 megapixels!

The WallScope has 28 projectors whose graphics are fueled by 31 nodes in a cluster. A series of 16 cameras on the floor create a 2D ‘multitouch plane’ so you can control the WallScope without making contact with the wall.

Video: GestureTek to let you interact with images projected from your phone

from VentureBeat:

GestureTek specializes in interfaces that track a user’s hand gestures and body position using a camera. The video below is a concept demo from interface designers TAT.

But GestureTek is building the technology for real (initially to be used by a single user, unlike the multi-user scenario shown in the video). An extra camera module and custom lens is required to track the finger on the projected image. The tracking should be quite accurate, with similar performance to the iPhone touch interface.

On the Intel booth at CeBIT 2010 we found Microvision with their motion-sensing, gun mounted laser projector… trust me, this is awesome!

Skinput turns your arm into a touchscreen

from Physorg.com: <-

A new skin-based interface called Skinput allows users to use their own hands and arms as touchscreens by detecting the various ultralow-frequency sounds produced when tapping different parts of the skin.

In Skinput, a keyboard, menu, or other graphics are beamed onto a user’s palm and forearm from a pico projector embedded in an armband. An acoustic detector in the armband then determines which part of the display is activated by the user’s touch.

Innovision’s Plug & Play ‘Holographic’ Projector (vid)

from Singularity Hub:

We may not have true holographic displays for several years yet, but in the meantime, there are plenty of people willing to provide us with something that looks pretty darn close. The latest of these is Innovision Labs out of Taiwan, which has started to sell its Holo AD, a 3D display case that is (nearly) plug and play.

For when 5 senses aren’t enough…

Every blog’s got to start somewhere, so I figured: Why not with Pranav Mistry’s highly anticipated SixthSense technology?

For a good rundown on what it’s all about, check out SixthSense Frees Data from the Confines of Paper or Screen.

SixthSense pushes gesture-driven digital responses to the limits. Simply draw the @ sign with your finger in the air if you want to check your emails on the wall. Use the same finger to draw a circle and see the time in the image of analog watch that appears on your wrist. Make a picture frame with your hands to take a digital photograph. With a look at your airplane ticket, SixthSense can tell you whether or not your flight is on time, as well as the reason of delay.
