Description

The paper describes a portable device for recording eye movements through Electrooculography (EOG). The gained bio signal can be used for monitoring the vigilance or basic eye control commands. The measurement is done with sticky electrodes; therefore it is non-invasive and easy to use. A special dedicated hardware device was developed for the purpose of data acquisition. The device has been tailored to be used in real life environments. The device allows rechargeable battery powered data acquisition of 3 EOG channels with 24bit resolution and 250Hz sampling rate per channel, over a period of up to 10 hours. Time information is provided by a built -in real time clock. The collected data is pre-processed and can be stored on a memory card or streamed directly via Bluetooth using a serial port profile to a mobile device. The mobile application can be used for data post-processing as well as for the adjustment of measurement device settings.
