This paper proposes a method for inducing drivers’ spatial attention by presenting visual stimulation in their peripheral visual field. Computer-generated images of forward driving scenes were projected on a screen 6 m in width, 1.8 m in height and with a 140° viewing angle. Their detection time of the visual stimulation in their central visual field was measured when visual stimulation was presented 1-5 s in advance on the right and left sides of their peripheral visual field in a viewing angle range of 10°to 40°. By varying the viewing angle at which the preceding stimulation was presented in the peripheral visual field and the time interval between the presentation of the preceding stimulation and the detected stimulation in the central visual field, conditions were found for assisting prompt detection of the latter visual stimulation.
