PURPOSE: A stick for each blind person is provided to sense obstacle of long distance through a sensor, thereby rapidly sensing the danger. CONSTITUTION: A bottom sensor unit(121) sense the crooked part of the bottom in lower part of a body part(11). If the bottom sensor unit senses the crooked part, a bottom vibrator(131) is vibrated. Side sensor parts(1221~1225) sense an obstacle by transceiving the wave length about front direction. If the side sensor part senses the obstacle, side vibrators(132~136) are vibrated. If the crooked part exists, a control unit controls the vibration number of the bottom vibrator. According to near-far of the obstacle, the control unit controls the vibration number of the side vibrator. |
