Vehicle driving support systems such as navigation and dead-angle warning systems make us safer and more comfortable. Existing systems, however, provide only visual and auditory information. Visual driving support systems may limit driver's field-of-view and auditory warning signals can lose in radio music, engine noise, or conversation noise. Therefore, audio and visual displays have some limitations on providing safer information. Tactile displays using vibration motors in the meantime can provide useful information regardless of restricted field-of-view and noisy environment. It may quickly draw the attention of the driver for issuing collision warning and directional cues. These intuitive and quick cues may be combined together with the visual and auditory display to give multimodal feedback to the driver. In this paper, a vibrotactile display device is presented for providing safety information to the drivers. Commercially available coin-type vibration motors are vertically inserted in the pads and an embedded microprocessor controls the motors sequentially. This system also has been evaluated by using driving simulator which has 6 D.O.F. Stewart-Platform and a 360 deg full-view using 8 projectors. Using driving simulator, some dangerous driving situations can be made safely and the effectiveness of the proposed vibrotactile display device can be evaluated. The evaluation results show that some navigation, lane and obstacle detection aids are recognized on the average of about 93% success rate.
