Novel User Interface for Semi - Automatic Parking Assistance System

This paper proposes a novel user interface for semi-automatic parking assistance system, which automates steering handling during parking operation. In spite of recent progresses of automatic target position designation method, manual designation is supposed to have two important roles. First, manual designation can be used to refine the target position established by automatic designation method. Second, manual designation is necessary for the backup of automatic designation method. Proposed user interface provides an easy-to-use manual designation method based on drag&drop concept. Target position is depicted as a rectangle in touch screen based HMI(Human Machine Interface). Driver can move the rectangle by dragging the inside of rectangle. Driver can rotate the rectangle by dragging the outside of rectangle. We compare the proposed method with multiple-arrow based method, which provides several arrow buttons to move and rotate target position, by measuring total operation time and clicking number. We can conclude that proposed method shortens the operation time and reduces the clicking number.
