A positioning device includes a body, a positioning module, a protruding member, a vibrator, a sensor and a processor. The positioning module disposed in the body is for sensing the location of the body. The protruding member is movably disposed at the body so as to expose from the body or position in the body. The vibrator is disposed in the body. The sensor disposed in the body is for generating a sensing value. The processor disposed in the body is for controlling the protruding member and the vibrator according to the comparison of the sensing value and an original predetermined value.一種指向裝置,包括一本體、一指向模組、一突起件、一震動器、一感測器及一處理器。指向模組配置於本體內,用以感測本體的位置。突起件可移動地配置於本體,以露出於本體外或內藏於本體中。震動器配置於本體內。感測器配置於本體內,用以產生一感測值。處理器配置於本體內,用以根據感測值與一出廠預設值之比較來控制突起件及震動器。100...指向裝置110...本體130a、130b、130d...突起件170a...按鍵180...控制件
