POPSThe future of interface design It's amazing to think what we can control and interact with, alot of these ideas were in Hollywood sci-fi only 10 years ago, the rate of development is staggering. Great article showing the technology and how we can use it in the real world.

POPSParalyzed Man Speaks Again Using Brain Implant So they knew his brain's speech centers were still functioning. They just needed a way to connect those speech centers to a speech synthesizer - an artificial mouth if you will. Researchers implanted a special kind of electrode in his brain, one that's "impregnated with neurotrophic factors" that encourage brain neurons to grow into and around the electrode. Essentially this electrode forms a very strong connection with brain neurons, which results in a strong signal that reliably comes from the same part of the patient's brain over time. Over a period of weeks, Guenther and his team worked to decode the signals coming from the man's brain. Eventually, he was able "to produce three vowel sounds with good accuracy," said Guenther. The man produces these sounds as quickly as he would normal speech, and Guenther added, "The long-term goal within five years is to have him use the speech brain–computer interface to produce words directly."

POPSAn End to Paralysis with Artificial Brain-to-Muscle Connectors Say the researchers: Until now, brain-computer interfaces were designed to decode the activity of neurons known to be associated with movement of specific body parts. Here, the researchers discovered that any motor cortex cell, regardless of whether it had been previously associated with wrist movement, was capable of stimulating muscle activity. This finding greatly expands the potential number of neurons that could control signals for brain-computer interfaces and also illustrates the flexibility of the motor cortex. Human implementations for the technology are at least a decade away, but this discovery could be a game-changer for dealing with paralysis. One possibility would be to connect the motor cortex with an area of the spine below an injury. Signals would be re-routed around the damaged spinal cord, and could allow the brain to regain control of the paralyzed body parts affected by the injury.

POPSThe Evolving AI Ecosystem He takes his theory further, all the way in to the tubes of the internet. In collaboration with Professor Tim Berners-Lee – the co-inventor of the World Wide Web – the pair have been investigating the next generation Web. “What is emerging now is a digital ecosystem,’ says Professor Shadbolt, ‘involving lots of simple systems which connect millions of complex ones – humans!” And there begins to be a certain amount of logic and a lessening of the fear I feel for the day when I am some robots whipping boy. We see such developments already in websites such as Facebook and Flickr, and programs such as Google Earth and World of Warcraft. We are being linked together, ever so slowly by a collective consciousness.

POPSScientists to study synthetic telepathy “Such a system would require extensive training for anyone using it to send and receive messages,” D’Zmura says. “Initially, communication would be based on a limited set of words or phrases that are recognized by the system; it would involve more complex language and speech as the technology is developed further.”

POPSScientists to study synthetic telepathy The brain-computer interface would use a noninvasive brain imaging technology like electroencephalography to let people communicate thoughts to each other. For example, a soldier would “think” a message to be transmitted and a computer-based speech recognition system would decode the EEG signals. The decoded thoughts, in essence translated brain waves, are transmitted using a system that points in the direction of the intended target. “Such a system would require extensive training for anyone using it to send and receive messages,” D’Zmura says. “Initially, communication would be based on a limited set of words or phrases that are recognized by the system; it would involve more complex language and speech as the technology is developed further.”

POPSAudeo - Think to Talk I first read about this in this month's Reader's Digest, which says that an Audeo device for telephones is in the works. That one would help ward off eavesdroppers, considering that you would no longer have to say anything aloud into the phone.

POPSIn the Works: MEMS Brain-Computer Interface As the electrodes are driven into the tissue, the software starts taking sample recordings to detect spikes of electrical activity at the electrode tip. When the software detects spikes, it moves forward in small increments and tracks how the signals change. After determining whether the signal has improved or gotten worse, it the algorithm moves the electrode to a new position and does more recording and comparing, driving the electrode in further if necessary until it finds the best signal. If the signal wanes, the algorithm will automatically adjust the electrode position to improve the signal.
