Integrated Wristband using an Inertial Measurement Unit and Electromyography Sensors to Control Robotic Car
Human-computer interfacing is being used widely to make more integrated and user-friendly alternative methods of communication between humans and computers. Various devices have been developed to give a new dimension to the way a user interacts with computers and machines. They allow multiple ways of machine input, unlike conventional human interface devices (HID) such as mouse and keyboards. These devices remove constrictions to allow users to interact with devices in other innovative ways. The focus of this work is to illustrate an example of a Human-Computer Interaction (HCI) device using electromyography (EMG) sensors in conjunction with accelerometer and gyroscope placed inside an armband to detect the EMG signals and gestures of the forearm. The processed data from the microcontroller is then used to control a robotic car wirelessly. The prototype device can be made more wearable, user friendly and portable with the implementation of a more compact armband in prospective projects.
