Scientist develops method for sound navigation

17.09.2002


Drawing on the expertise of the blind, a University of Toronto professor is “teaching” electronic devices how to navigate using surrounding sounds.

“The goal was to build a system that mimics the acoustic navigation abilities of blind people,” says Professor Parham Aarabi of the Edward S. Rogers Sr. Department of Electrical and Computer Engineering. He has developed a method by which a device fitted with as few as two microphones can combine the information from sounds around it to locate and orient itself, in the same way that an animal uses its two ears. This method achieves the same result as radar but is more adaptable to different technologies, he adds.

Eventually, the technology could be used in robotics or personal communication devices, such as cell phones or hand-held computers. For example, says Aarabi, cell phones that combine the signals from many microphones could filter out background noise and transmit only the clear voice of the cell phone user.



Aarabi says that communications devices using this technology could become available to consumers within five to 10 years. The study, funded by the Canada Research Chairs Program and the Canada Foundation for Innovation, will appear in an upcoming issue of IEEE Transactions on Systems, Man and Cybernetics, Part B.

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
