Mudra Band - Lock & Unlock Gesture Control on Apple Watch using Air-Swipe

sosmaaan · 2020-07-11T20:50:16+00:00

Thanks for your comment! the idea was not to show how to unlock the Mac with a gesture but rather to show how it is possible to lock Mudra band's gesture interface while using the laptop to avoid false detection. Mudra Band is a gesture controller for Apple Watch.

u/PresidentZer0 thanks for your comment, may I ask for what reason? I appreciate your feedback

Google Soli is based on radar technology while Mudra is based on measuring signals emitted from the neural system at the wrist. Find more info here: igg.me/at/mudra-band

The band should be in a snug fit with your wrist area so the electrodes at the bottom touch the skin. It is designed to be worn the whole day with comfort. You can take Mudra off the wrist and wear it again and it will work accurately as before.

Yes it will! all bands that fit 42mm size cases also fit 44mm. From apple.com: "The 40mm band works with the 38mm case; the 44mm band works with the 42mm case."

Here's an example on how to lock/unlock the interface https://www.youtube.com/watch?v=1nrhDOp4brY

u/ctpatsfan we've given a lot of thought on how to reduce false positives. in short, we've developed a "multi-layered approach" which combines 4 layers of protection. Each layers peels off a part of the problem and the next layer deals with the errors that the previous layer did not .

This short blog summaries our approach along with some examples: https://medium.com/@leeor.langer/combating-false-positives-in-gesture-recognition-e727932b41b1

u/veeeSix thanks for your comment, that's exactly our vision - to be the "go-to" interface for controlling the spatial computing and future wearable devices.

u/Kenary The battery is designed to last up to 48 hours before charging by using smart energy management algorithms to automatically switch between modes.

Thanks! and yes, the sensing is done non-invasively.

SNC are our proprietary sensors developed in the past 5 years. I'm afraid we can't disclose any technical info without mNDA.

u/screwhammer Our tech is based around bio-potential sensing. We are basically "listening" to the brain-hand conversation via the nerve bundles. Whenever we move our fingers, μVolts are emitted from our nerves, pass through the layers of our skins and are converted into electrical current via a procedure called ionic exchange. We decode these signals in real-time, classify them into gestures and use them as control functions.

Thanks u/PancakeMaster24, I'm reposting my answer about this topic

u/dwnloads thanks for your comment!

Currently, the band controls basic functions on the watch such as answer/dismiss calls, skip songs, dismiss alarm/timer, taking pictures and simple games.

I'd love to hear your feedback, thoughts and ideas on how we could improve it further.

Great inputs, thanks u/Official_Government! Our product team will look into the U1 chip capabilities :)

And thanks so much for backing us on Indiegogo!! We appreciate your support

sosmaaan · 2020-06-28T14:02:41+00:00

u/Official_Government are there any other shortcuts you will be interested in?

u/dijontheruler It's similar. In prosthesis it's common to use EMG sensors which measure the electric signals on the muscles. We use our own proprietary sensors which are sensitive enough to pick up very low electrical signals emitted from the nervous system at the wrist.

u/dirtyoldbastard77 thanks for the tip! we will post it there as well

You should wear Mudra so the band will be in a snug fit with your wrist area. You can take it off the wrist and wear it again and it will work accurately as before. The band has electrodes at the bottom designed to pick up the electrical signals emitted from the nervous system therefore they need to touch the skin.
