DeepHand motion tracking enters the VR arms race

The VR arms race is in full flight, and hands seem to be the next frontline in the battle, whether that's fought with infrared cameras, electromagnetic sensors, handheld controllers like those used by the HTC Vive, Playstation Move or Oculus Touch, or even full-body exoskeletons. Now, a team at Purdue University is capturing hand movements with depth-sensing cameras, and using a deep-learning network to understand millions of possible hand positions in order to display them accurately in the virtual world.Read More


Laser-fueled vortex creates nanotube forest

While small in size, carbon nanotubes can be mighty in their applications. But manipulating carbon nanotubes can be tricky, considering that their diameter is about 50,000 times smaller than a human hair. Researchers at Purdue University have just come up with a way to force carbon nanotubes to get in line – literally – by using electrical pulses and a vortex created by laser light.Read More


Battery anodes made from pollen are nothing to sneeze at

As our dependence on mobile devices grows and we continue the shift to electric vehicles, there is a need to not only develop better performing batteries but find more accessible and sustainable materials with which to build them. To this end, researchers have now developed an anode for lithium-ion batteries using something those with allergies certainly wouldn't miss: pollen from bees and cattails.Read More


"Light recycling" tech could save incandescent bulbs from obsolescence

Incandescent light bulbs may put out a warmer-looking, more familiar type of light than LEDs or compact fluorescents, but they're far less efficient – the majority of the energy they use is wasted, mainly in the form of heat. Technology may save them yet, however. Scientists at MIT and Purdue University have developed an ultra-efficient new incandescent bulb that reuses the heat it gives off, converting that heat into more light.Read More


Smart capsule keeps hold of payload until reaching its target

We have drugs to treat nasty conditions like irritable bowel syndrome and Crohn's disease, but unfortunately their effects are often blunted by little stumbling blocks known as the stomach and the small intestine. These body parts are prone to absorbing certain medications before they can do their best work. But a new type of capsule holds onto its payload until reaching the large intestine, making for more effective delivery. Read More


MirrorMirror reflects you and your digital info

Doing your hair and brushing your teeth are chores that may become a little more interesting and fun with a new mirror that, besides reflecting, can also display emails, news threads, tweets, public transport times and all kinds of online data. That's because a student team from the College of Science and College of Engineering at Purdue University has created a mirror that doubles as an information interface. Keeping up-to-date with bus schedules inspired the team to come up with the info-mirror.Read More


Packing peanuts could be reused in better batteries

When a new lab was recently being set up at Purdue University in Indiana, a lot of the equipment arrived in boxes full of protective packing "peanuts." Unfortunately, few facilities exist for recycling the little pieces of foam, so they typically end up sitting in (or getting blown around) landfills for several decades. A team of Purdue researchers, however, discovered that they could find use in better-performing lithium-ion batteries. Read More
