Microsoft has always been innovative when it comes to computer and now it’s developing a technology that will allow you to control computer without a controller and with your muscles twitches like finger-waggling and pinching.

What’s new about this technology??

This technology depends on the electromyography (EMG) which senses the electrical charges formed by muscle cells after they have received a signal from the brain. If you put an armband on the muscles of the forearm which controls the movement of fingers, you can use EMG to detect the movement. The special software then converts these EMG readings to gestures and the computer accepts these gestures as mouse, normal keyboard, or touchscreen inputs. The following video shows one of the early prototypes developed by the company that gives a good beginning to EMG-based human-computer interaction.

How to interact with it??

Microsoft has mentioned in its recent patent application that the EMG device doesn’t necessarily have to be an armband: It could be a wristwatch, an article of clothing, or even a pair of spectacles. But it’s necessary that these EMG controllers would be connected to a wireless hub and will take power from the batteries. Also, many controllers can be put on at the same time.

How to detect the response??

The company says that the EMG armband would likely consist of actuators that hum or vibrate in response to your gestures. A pinch gesture may produce a light vibration around the armband giving you a short, sharp buzz on the crest of your arm.

Where to place the EMG device??

It is important to place the EMG device at the proper place. If you have a particularly fat, boney, or muscular arm then it is difficult to get good results.

Accuracy needed

Guitar Hero is being played in the video and it doesn’t show that EMG can be used to finely control a pointer on the display. This shows that Microsoft as excluded the most important thing from its patent filings i-e Accuracy.

This new technology looks like a smaller version of Kinect. Let’s see how far the company succeeds in its research.
