A new kind of 3D display could take the form of an acrylic cube with an image inside, which can be erased and rewritten to easily. The new technique can be used to make 2D, 3D and even animated images.

Ordinarily, if you want to separate two objects that are glued together, harsh solvents or mechanical force are required – either one could damage the items. A new glue, however, releases its bond by simply turning to gas.

​Eye-tracking systems certainly would add a lot to augmented reality glasses, but their integration into such eyewear has been limited because they require so much power. That said, scientists have now developed eye-tracking glasses powered by nothing but onboard solar cells.

Indoor climbing walls don’t always capture the nuances of nature, so researchers developed a way to bring the outdoors in. Rather than recreate an entire rock formation, they made models of the key parts of the geometry and arranged them on an artificial wall to replicate the real thing.

If you've so far resisted the temptation to buy yourself a smartwatch, then a new prototype device called Cito could have enough moves to one day change your mind: It can rotate, lift, twist and more to grab your attention.

Wind instruments can take almost any form. Weirdly-shaped instruments are more difficult to design, however, which is where a new computer program called Printone comes in.​

Voice control is one option for one-handed smartwatch usage, but researchers from Dartmouth University are developing another. Their WristWhirl prototype can be controlled by making joystick motions with the hand of the arm that's wearing it. ​

Spray paint is a notoriously tricky medium to control. Fortunately for would-be muralists everywhere, researchers have invented a "smart" spray paint system that can use regular cans of paint to re-create photo images as spray-painted murals on walls or other large surfaces.

A digital "magic wand" prototype has been created that allows users to securely connect devices to a Wi-Fi network simply by pointing the device at them.

Computer users may sometimes forget to log off when accessing sensitive data. That's why Dartmouth College computer science student Shrirang Mare is developing ZEBRA. It utilizes a sensor-equipped bracelet to continuously authenticate a user's identity.
