Type-Hover-Swipe in 96 Bytes: A Motion Sensing Mechanical Keyboard
Project website:
http://research.microsoft.com/en-us/p...
We present a new type of augmented mechanical keyboard, capable of sensing rich and expressive motion gestures performed both on and directly above the device. Our hardware comprises of low-resolution matrix of infrared (IR) proximity sensors interspersed between the keys of a regular mechanical keyboard. This results in coarse but high frame-rate motion data. We extend a machine learning algorithm, traditionally used for static classification only, to robustly support dynamic, temporal gestures. We propose the use of motion signatures a technique that utilizes pairs of motion history images and a random forest based classifier to robustly recognize a large set of motion gestures on and directly above the keyboard. Our technique achieves a mean per-frame classification accuracy of 75.6% in leave-one-subject-out and 89.9% in half-test/half-training cross-validation. We detail our hardware and gesture recognition algorithm, provide performance and accuracy numbers, and demonstrate a large set of gestures designed to be performed with our device. We conclude with qualitative feedback from users, discussion of limitations and areas for future work.

This beautiful American contra luz opal stone weighs approximately 119.0 carats and measures 46.0 x 44.0 x 10.1mm (1.81 x 1.73 x 0.39 in). It was found in Opal Butte, Oregon. What makes this piece really unique is the brown nebula-like cluster formed inside it. Contra luz opals are similar to crystal opals, which means they are transparent, but have this ability to also create color flash when light passes through from the opposite side.

Manu Prakash: A 50-cent Microscope That Folds Like Origami
Perhaps you've punched out a paper doll or folded an origami swan? TED Fellow Manu Prakash and his team have created a microscope made of paper that's just as easy to fold and use. A sparkling demo that shows how this invention could revolutionize healthcare in developing countries … and turn almost anything into a fun, hands-on science experiment.

Exclusive demo: The new Photosynth lets you swoop through 3D panoramas
In this talk from TEDGlobal 2013, Blaise Agüera y Arcas of Microsoft introduces us to the new Photosynth, a set of tools which lets the everyday photographer create swooping, movement-filled 3-dimensional panoramas of spaces that look like they were created by special effects masters.Read all about the evolution of Photosynth 2: http://blog.ted.com/2013/12/11/blaise...

The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes and, so far, this method has been used to levitate lightweight particles, small creatures, and water droplets.
The acoustic axis of the ultrasound beam in these previous studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers. In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and moved three-dimensionally by localised ultrasonic standing waves, which were generated by ultrasonic phased arrays. Our manipulation system has two original features. One is the direction of the ultrasound beam, which is arbitrary because the force acting toward its centre is also utilised. The other is the manipulation principle by which a localised standing wave is generated at an arbitrary position and moved three-dimensionally by opposed and ultrasonic phased arrays. We experimentally confirmed that various materials could be manipulated by our proposed method.
