Muscle contraction: The subtle way of human computer interaction

The advent of new technology has opened opportunities to the computer users to consider alternate ways for humans to interface with machines. Research groups are looking to use computer interfaces that can allow users to communicate with devices in a subtle way and allow virtual reality environments to create an immersing experience. Electromyography based wearable input device can interface with mobile devices in a subtle way. Electromyography can also be used for interactive computer gaming as well as to control flights through virtual joysticks and controllers. This study provides a brief review on various ways for humans electromyography (EMG) signal to interface with machines. Therefore, the crux of this study is to overview the up to date developments and research related to the EMG interface with the wearable devices. This study further opens up a passage for researchers and end users to advocate an excellent understanding of EMG interfacing with mechanical devices.
