Muscle Computer Interface

Muscle-computer interfaces have been around for some years but have only begun to develop into a separate interface paradigm relatively recently. Using a similar approach to brain-machine interfaces, muscle based interfaces detect the electrical signals just under the skin as muscles move, and use this to guide actions.

For example, one muscle based machine interface for a wheelchair, works by moving forward when the person smiles, turning left when they close their left eye and turning right when they close their right eye. The muscle movements control machine actions.

Meshworm: A robot made of a single Artificial Muscle
Meshworm is the prototype proof of concept for a new type of artificial muscle, based on an in-depth study of the movement patterns of the common earthworm, and shows how it is possible to create a 'soft' robot or prosthetic that is basically a single muscle and very little else.

Targeted Muscle Reinnervation Increases Prosthetic BMI
A Journal of the American Medical Association study looked at targeted muscle re-innervation to see if it did indeed have as much success as studies conducted by those with a vested interest in a positive result.

A novel interface paradigm computer, the QB1 is the brainchild of one Fr?d?ric Kaplan, an engineer with a background in robotic systems for Sony. He worked with designer Martino d?Esposito of EPFL in France, to create a computer system with no mouse, no keyboard, just an on/off switch, and the ability to recognise and respond to gestures.

Prototype Ionic Artificial Muscle Doubles as a Speaker
A prototype ionic muscle has been created by researchers at Harvard University. Not very strong, yet exceptionally pliant, its main claim to fame is that it can flex thousands of times per second, and being completely non-electronic, is capable at least in theory, of conversing with the neurons of the body in their native ionic tongue.

Flexing, clear computer components
In an augmented world, you may well have one or more of three distinct types of computer interface on, or even in your body. There are augmenting reality devices, prosthetic components, and direct-wired virtual reality interfaces. All three share aspects in common. Among them, that they all require considerable computing power as close to the implant as possible.

This book, by author and renowned VR expert Howard Rhinegold, was first published in 1991 ? nearly twenty years ago. All those years back, Rhinegold still managed to predict VR applications that are only just being realised today. Walking through computer mediated environments, with the power of physical legs; having targeted muscle re-enervation provide the neural connectivity of physical legs if you have none. Doctors treating patients remotely, or operating on precise mock-ups of patients before they lay eyes on them for the first time. Touring buildings, rendered in 3D, from blueprints alone.
