4 1. Introduction Research context Research gap Research objectives

5 1. Introduction Research context Driving requires neuropsychological capabilities: visual, cognitive and motor functions Research gap Observational error assessments behaviour and performance assessments Research objectives Investigating visual-motor coordination in naturalistic driving using spatial tracking and analysis technologies, and to promote safe driving.

6 2. Research Framework Tracking eye movement in driving studies What the driver gaze at, for how long, and the sequence of the gazing objects. GPS/GNSS tracking vehicle movement Speed control, lane maintenance, etc Combining eye tracking and vehicle movement tracking What and from where the driver gaze at, for how long, and how he/she control the vehicle using the visual information. Reflecting the visual-motor coordination of the driver.
