His first symptoms were visible muscle twitches. Then, he found he had trouble surfing, a regular hobby along with snowboarding and scuba diving. An evaluation by a foot doctor led to a trip to an orthopedic surgeon, followed by a referral to a neurologist, then to UCSF Medical Center hospital. Valor hoped for cancer or another illness that might be cured. His ALS diagnosis came soon after. By 2008, he couldn't control a computer mouse and he retired as a network operations manager overseeing several US offices for Daimler.
Valor iphone screen protector film transitioned to using an infrared camera that can track his eye movements across his computer monitor to allow him to write, He wears a sensor taped to his cheek that, when he twitches, can activate a buzzer to call an attendant, His meals are served to him via a feeding tube, He is hoisted onto a rolling transport chair for showers, A machine helps him breathe, Despite his condition, he discusses how he refuses to "go away," now writing a blog chronicling his life with ALS, participating in drug trials, and advocating for the ALS community..
Writing to CNET using eye-tracking technology on his computer, he said he keeps busy socializing online, helping other ALS patients with their computers, and managing different projects involving the ALS community. "I am fulfilled in this new career," he said. Valor's ALS outreach led him to the Emotiv project, and his background in IT made him an obvious fit for the test. Emotiv, founded in 2011, is among a handful of companies, including InteraXon and NeuroSky, working to take electroencephalography, or EEG, technology -- which has been used by doctors and scientists for decades to study brain activity -- and bring it into the consumer world. These commercial devices, which use EEG sensors to decipher the brain's electrical activity along the scalp, offer users a way to track brain health and provide a new form of gaming.
Emotiv currently sells a wearable headset called the EPOC, which starts at $399, that's used for research, and it plans on coming out with a second headset called Insight for consumers in early 2015, starting at $299, Both devices iphone screen protector film are simply worn on a user's head and don't require any implants or surgery, so they can be removed about as easily as a hat, The battery-powered Insight, which Valor used in the experiments, is intended to be a wearable device for everyday use by anyone to assess brain health and well-being, The device can interpret brain signals, allowing a user to perform a handful of commands on devices compatible with the headset, including flying a toy helicopter, using only their mind..
Valor could use the Insight headset to send commands by thinking certain words, such as "down" or "right." Those commands were then transmitted over to a tablet computer and processed through Accenture and Philips software to control a handful of Philips products, including the Lifeline medical alert system, a television, and lighting. The commands also appear on an eyeglasses display device, providing feedback to Valor. Valor said there were obvious advantages to the Emotiv headset. He noted that the headset seems to work in sunlight, when the infrared eye-tracker could be more challenging. In more serious cases, two of his friends lost the ability to move their eyes, and thus their last mode of communication.
Valor and others affected by iphone screen protector film ALS have a spectrum of technologies available so they can function as much as possible like they did before the disease hit, Once a patient loses more motor abilities, they can transition to another type of technology, such as switching from tapping on a tablet to visual inputs with an eye-tracking sensor, However, once full paralysis takes place, there often is no way to reach out anymore, Jacquellyne Hengst, director of development at the Philadelphia-based ALS Hope Foundation, said that for those patients served by her organization, she will sometimes simply sit with them, hold their hand and look into their eyes..
For those cases, brain-computer interfaces, or BCIs, hold promise, though the technology remains mostly in the research phase. Such technologies could allow people with extreme physical disability -- including those with ALS, brain-stem strokes or cerebral palsy -- to type out an email, operate a robotic arm or wheelchair, or move a cursor by using their thoughts. Sara Feldman, a physical therapist and assisted-technology professional at the MDA/ALS Center of Hope clinic, which is funded by the Philadelphia foundation, said many patients most fear losing the ability to interact with others. Any technology, she said, that could provide a channel of communication for patients who can't move would be life-changing.
"It is so important, because communication is so important to people," said Feldman, who wasn't involved in the Emotiv project, While her organization takes part in projects involving brain-computer interfaces, she noted, "That's taking a lot of time and research."So far, the next step for Philips, Accenture and Emotiv is unclear, The team said they were able to prove their idea works and wanted to talk about it publicly to draw in more ideas and iphone screen protector film attention to see if that concept can one day reach the market, But there remain more questions, including how to ensure the system can function for patients at differing stages of ALS, Also, converting Emotiv's Insight headset into a medical product would require substantially more reliability and stress testing, Emotiv CEO Le said..
