Abstract

The sense of vision of the driver is almost wholly responsible for the processing of information in the driving situation. This project was designed to develop a transportable recording system that can be used in moving vehicles to record driver eye movements, and to investigate human response times to signals in peripheral vision. An amplifying and recording system was designed and developed which may be used in moving vehicles to record driver eye movements with a minimum of interference to driver activity. The system was designed so that it could be operated by self-contained batteries in as much as the line voltage of standard automobile electrical systems varies considerably. The system appears suitable for making eye-movement recordings as larger, less easily transported bioelectric recording equipment. Electrode preparation was the most critical factor associated with making good eye-movement recordings. Electro-depositing equipment was constructed for making chlorided silver electrodes. Response times to signals in peripheral vision were investigated. Research results indicated that response times are unusually long in a complex visual situation.
