Mudra Band - Touch Free Control for Apple Watch
How come you operate your phone with one hand, but your watch requires two?! With Mudra Band, you get to control your watch using only the hand that wears it, even when you have gloves on or when your hands are wet.
Urgent calls that demand your response have a way of coming in just when you’re trying to get other things done. Mudra Band lets you accomplish your tasks without using your nose to take or dismiss important watch events.
With Mudra Band, you don’t need to stop, stand, look at the watch, touch it, or use your other hand to control your musical soundtrack. Simply move your fingers to switch tracks, skip around, adjust the volume, etc., and keep exercising without interruption.
When you intend to move a finger, electrodes in the Mudra Band capture the neural signals sent from your brain, through the wrist, to your fingers. Our patented SNC sensors capture the signals, while our deep learning AI algorithms decipher the signal pattern and classify which finger is being moved. Finally, we bind each signal pattern to a control function on your watch.
Simple & Intuitive
The Mudra band offers a delightful and enjoyable interaction and immerses the user in the watch experience with gestures that are simple to perform, intuitive and easy to remember. Mudra gestures are defined based on extensive behavioural research, in order to provide the most natural interaction method.
Mudra supports discrete, continuous, and air-touch interactions.
- Discrete gestures are individual finger movements – such as a single finger moving, or the soft tap of a finger on the thumb
- Continuous gestures are various fingertip pressure gradations applied to physical objects or other fingers
- Air-touch gestures combine fingertip pressure and an air mouse – such as sliding to unlock
Accurate Gesture Recognition
Mudra classifies user gestures by processing an unstructured neural signal pattern. To solve the challenge of different ways an individual performs gestures and the large variance in wrist sizes, we implemented the most advanced Artificial Intelligence and Deep Learning algorithms.
Minimal False Detection
A common question is "what happens if I just scratch my head or unintentionally moved a finger?" We are building a unique algorithmic pipeline which learns intended gesture vs. unintended movement, and connects it with the context of the user's activity, so you can use Mudra and use your fingers at the same time.
The Mudra Band is compatible with Apple Watch series 3 and above, and with iPhone 7 and above. The band comes with an adapter that fits 38mm, 40mm, 42mm and 44mm watch sizes and can lengthen or shorten the circumference of the band for different wrist sizes.
What are Biopotentials?
Biopotentials are electric potentials (typically on a scale of micro-volts) produced by the electrochemical activity of excitable cells in the nervous system of the body.
How does Mudra measure biopotentials from the wrist?
The Mudra device uses patented SNC (Surface Nerve Conductance) sensors which convert ionic electrical activity from the surface of the skin to electric voltage by a process of ionic exchange.
Such data is utilized to analyze the motoric actions performed by hand and finger movements. Even subtle actions, such as slight finger movement or pressure between two fingers, are registered on the SNC sensors.
A look at Mudra's technology
The idea of measuring biopotential from the surface of the skin isn't new – historically this phenomenon is used to diagnose various diseases, such as motoric injuries (EMG) and heart arrhythmias (ECG) using clinical sensors and systems.
The Mudra device utilizes a miniaturized patented sensor array (SNC – Surface Nerve Conductance) to perform ionic exchange on biopotentials sampled through the human wrist. In contrast with EMG sensing, the wrist area has no large muscles groups therefore the SNC sensors were specially designed to account for a very low SNR input.
The Mudra device digitizes this valuable data and transmits it to the phone or watch, where our algorithms analyze this activity. We tailor each user’s unique movement signatures to his\her physiology via a short calibration procedure. Finally, we empower a user with a touchless experience by associating app functions to intuitive movements.
The company has several granted patents in the US and China.
Our vision is to make the human hand itself the universal device for interacting with technology. We imagine a future where using digital devices is as natural and intuitive as organic, real-life experiences - and where humans can use wearables to share skills, ideas, emotions, and movement with each other and with computers.
Since 2018, the Mudra Inspire dev kit has been marketed to global electronics corporations and software solution providers, who use it to define interaction methods for smartwatches, AR glasses, VR headsets, mobile phones, TVs, gaming, robotics, digital health, and more.
