Wearable EMG Assistive Technology

Reprint from Wearable Technology Insights 

NeuroNode is the world’s first wearable EMG assistive technology device developed by Control Bionics. It gives those with ALS/MND, spinal cord injury, or any other condition causing paralysis and loss of speech a connection to the world. The NEURONODE uses the body’s bioelectric EMG (electromyographic) signals to completely control a computer to generate speech, browse the web, listen to music, and more. It is resistive/augmentative communication (AAC) technology that is easy to use and works for conditions like ALS (Lou Gehrig’s Disease), MND, SCI, or cerebral palsy.

EMG, or “electromyography,” is the measurement of electrical activity associated with the activation of a muscle group as detected by non-invasive electrodes on the surface of the skin. EMG signals have been used in clinical and research settings since the 1980s for things like diagnosis of neuromuscular diseases, rehabilitation, and controlling prosthetic devices.

It has taken more than 11 years developing EMG technology as a communications channel for people with severe paralysis. EMG technology is most promising because it taps directly into the available controllable signals being sent from the brain to muscles, even if they are not detectable physically. The NeuroNode can detect and amplify Read the remainder of this entry »

Facebook launches “Automatic Alternative Text”

Posted April 6, 2016 By Lee Learson

Social media platforms may be a great way of telling the world about your life, but not everyone can appreciate these moments in full.

Facebook is launching “automatic alternative text”; a tool that uses object recognition technology to identify and describe an image, so that visually impaired and blind people using screen readers will be able to hear-and therefore visualize-what’s in a photo posted on the social network.

“With more than 39 million people who are blind, and over 246 million who have a severe visual impairment, many people may feel excluded from the conversation around photos on Facebook,” Facebook’s Shaomei Wu, Hermes Pique, and Jeffrey Wieland, said in an online post.

Before the announcement, screen readers would only be able to tell users who posted the Facebook post and that an image was uploaded.

However, the tool will now able to say what the image may contain, from simple objects like “car” to “three people, smiling, outdoors”. Currently, the software can identify around 100 types of objects and scenes, including those associated to nature, sports and transportation. Read the remainder of this entry »
