The Emotiv EPOC neuroheadset comes with a built-in 2-axis gyroscope, which enables a range of additional functions. (ex. cursor control)
Understanding the Inertial Sensor Tab
The Inertial Sensor Tab in the Emotiv Xavier SDK allows you to activate the neuroheadset's gyroscope and link it to the control of your computer's cursor.
The left side of the Inertial Sensor Tab display is a visual representation of the current contact quality of the individual neuroheadset sensors. The display is a smaller copy of the contact quality visualization found on the Insight SDK's Set Up tab.
The right side of the Inertial Sensor Tab provides a visual representation of the gyroscope's relative position and the controls to activate and deactivate this feature along with a slider bar to make sensitivity adjustments.
