Sitting in a meeting room in a startup office in Lisbon, I silently typed the answer to a question only the person opposite would know the answer to. What Unbabel, a language translation company, has developed a wearable device called Halo that allows users to communicate using their thoughts. The device uses an EMG interface embedded in a flexible sleeve to capture electrical impulses from muscle movements. These impulses are then translated into text using Open AI ChatGPT 3.5. Users have complete control over the messages generated and can approve the final output. Unbabel is working with the Champalimaud Foundation to deploy the device to ALS patients, with plans to expand its use to other patients who struggle to type. The current version of Halo allows for communication at a rate of 20 words per minute, with a target of 80 words per minute. The ultimate goal is to achieve superhuman communication capabilities.
