Nowadays wearable computing is one of the most popular trends in the technologic community. Seems clear that wearable computing will change completely the way we interact with our gadgets. After the Google Glass announce everybody realizes the potential of this kind of gadgets and this week an important advance in the field has been publish.

Researchers from the University of California at Berkeley and Davis have developed a micro-chip that allows 3D gesture detection that could be a big improvement in wearable gadgets. This technology is called Chirp and the company ready to sell it is Chirp Microsystems. Chirp requires building electronics and an ultrasound chip in the device you want to control. The team believes that their technology will be ideal for gadgets like Google Glass but also for any kind of thing we wear like helmet or in our clothes.

Chirp uses sonar via an array of ultrasound transducers that send pulses that when found movement returned to the device where the difference in time is measured. When two arrays of transducers are used 3D detection in a range of 1 meter is accomplished.  Due to the use of sound signals, the chip can be implemented with low-speed electronics reducing dramatically the power consumption. Richard Przybyla, one of the designers of Chirp, assures that the battery lasts for 30 hours.

Chirp is one of the latest advances in gesture recognition like Microsoft Kinect or Leap Motion. This is a field with a lot of researchers and companies working on and for sure this will not be the last advance we heard about.

What do you think about this advances? Do you think they can be a big impulse for wearable computing?
