The layout of switch button was addressed in the many previous studies. The most of them was related with the switch buttons controlled by human hands or fingers. This study addressed the layout of switch button that is controlled by the human foot. Human performance (e.g. movement time and error rate) was measured according to the number of button and the layout pattern. The human performance was decreased with increase of the number of button. The number of button which can be recommended was less than 4buttons in this study. On the other hand, it has been reported that foot movement rotating foot ankle is more efficient than foot movement straightly moving foot itself. However, the button layout leading rotating foot ankle was not significantly superior to the other button layouts in this study.

Traffic safety issues have recently been seriously magnified, due to child deaths in apartment complexes and parking lots. Accordingly, traffic safety technologies are being developed to recognize dangerous situations on living roads and to provide warning services. In this study, a collision detection algorithm was developed to prevent collision accidents between moving objects, by using object type and location information provided from CCTV monitoring devices. To determine the exact collision between moving objects, an object movement model was developed to predict the range of movement by considering the moving characteristics of the object, and a collision detection algorithm was developed to efficiently analyze the presence and location of the collision. The developed object movement model as well as the collision detection algorithm were simulated, in a virtual space of an actual living road to verify performance and derive supplementary matters.
