Clever vibrational hack turns iPhone into spyPhone

Researchers at Georgia Tech have demonstrated how a smartphone accelerometer (the sensor that detects the phone’s orientation) can sense nearby computer keyboard vibrations and decipher complete sentences with up to 80 percent accuracy. Georgia Tech’s Patrick Traynor (pictured) is presenting his team’s work this week at the 18th ACM Conference on Computer and Communications Security […]

Videos reconstructed from brain scan

Using MRI brain scans, computational models and a large quantity of YouTube videos, University of California, Berkeley researchers have demonstrated how people’s dynamic visual experiences can be reconstructed. The image at right shows the source video image and the reconstructed image. The videos themselves can be seen on YouTube. Reporting on their work in the […]

Motion capture for everyone, anywhere, anytime

Current motion capture techniques use cameras to meticulously record the movements of actors inside studios, enabling those movements to be mapped onto digital models. Now, a new system which places the cameras on the actors themselves permits motion capture to occur almost anywhere. The scientists at Disney Research and Carnegie Mellon University who developed the […]

Harvested TV, radio signals power devices

Georgia Tech scientists using a novel printable ultra-wideband antenna have shown that the ambient electromagnetic waves from TV stations, radio stations, satellites and cell phones can be harvested and used to power a range of electronic devices. “There is a large amount of electromagnetic energy all around us, but nobody has been able to tap […]

Error tolerance could slash computer energy use

The amount of electricity required to run today’s computers, data centers and mobile devices is increasing rapidly and this growing hunger for power makes the digital world a significant greenhouse gas contributor. Most energy saving projects so far have focused on more efficient cooling systems or energy-saving power modes, but researchers from the University of […]

Schizophrenic computer models mental illness

A computer network that emulates schizophrenia is providing University of Texas at Austin researchers with important insights into the inner workings of schizophrenic brains. Writing about their work in Biological Psychiatry, the researchers explain that the computer neural network they used simulated the excessive release of dopamine in the brain. “The hypothesis is that dopamine […]

“Paperphone” prototype demonstrates bend gesture interface

Researchers from Queen’s University in Canada have developed a prototype flexible smartphone interface that allows users to interact with applications on the phone by bending and manipulating the display. The prototype uses a 9.5 cm (diagonal) thin film flexible E Ink display that has been customized with pressure sensors that monitor the user’s actions and […]

Electronic components made from human blood

Indian researchers from the Changa Education Campus in Gujarat have demonstrated a memristor made from human blood and are now planning the creation of other electronic components, such as transistors and capacitors, composed of human tissue. The findings are reported in the International Journal of Medical Engineering and Informatics. The researchers say the development of […]
