As reported by engadget,
When Wearable Devices, the startup that’s behind the Mudra Band, first pitched the device to Indiegogo backers, it did so by playing up the fact it could let you use the Apple Watch without touching it with your non-watch hand. But the company told Engadget it’s been working on accessibility use cases as well. In one instance, they built a proof of concept that allows ALS patients to quickly type using a virtual keyboard. In another example, the company used the wearable to give an IDF veteran whose injury left them with a heavily clenched fist the chance to learn to play the piano.
Wearable Devices is working with universities in the US, Israel and Japan to develop those use cases. In the meantime, the Mudra Band is available to pre-order today for $179 ahead of its release in March.
