EOG signal acquisition using reconfigurable analog devices and use it to control wheelchair movement

Abstract EN

This paper present an electrooculography (EOG) acquisition system based on reconfigurable devices.

The field programmable analog array FPAA is used for extract the EOG signal which makes it possible to design flexible and adaptable EOG applications with the functionality that can be dynamically changed or extended.

The EOG signals in this system have been acquired using a five-lead configuration.

The FPAA has online Programmable feature that can dynamically be adapted the amplifier to detect the signal, it is reduced the circuit complexity and succeeded in detect these weak signals which coupled with huge noise.

The system is established and its performance was tested.

It is used to guide an autonomous robot (wheelchair) as a system to help the people with severe disabilities.

It was found that the proposed system could produce clear EOG signals which are suitable for many activates and the success percentage of the system is 95%.
