Abstract
A motion guiding apparatus includes a guiding device and a mobile unit. The guiding device includes a main body, an arm piece, and a linear light source. The main body is in connection with the arm piece and arranged on a reference surface. The linear light source is arranged on the arm piece and forms a reference light line on the reference surface and a direct light line on the main body. The mobile unit is capable of capturing an image showing the reference light beam, the direct light beam, and a reflected light line. The mobile unit can also compute an angle formed between the reference light line and the reflected light line to obtain a relative angle between the mobile unit and the linear light source, so as to move in accordance to the relative angle. A motion guiding method is also provided.
