MOTION GUIDING METHOD AND MOTION GUIDING APPARATUS
First Claim
1. A motion guiding method, comprising:
- disposing a linear light source at a distance above a reference surface;
producing a reference light beam on the reference surface and a direct light beam on an outer surface by the linear light source, with one edge of the outer surface being adjacent to the reference surface;
capturing an image by an image-capturing module, with the image showing the reference light beam, the direct light beam, and a reflected light beam generated by the direct light beam striking the reference surface;
computing a reference angle formed between the reference light beam and the reflected light beam shown in the image to obtain a relative angle between the image-capturing module and the linear light source; and
moving the image-capturing module based on the relative angle.

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 beam on the reference surface and a direct light beam 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 beam. The mobile unit can also compute an angle formed between the reference light beam and the reflected light beam 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.

5. A motion guiding apparatus, comprising:
-
a guiding device comprising; a main body having a first end portion and a second end portion, the first end portion being in contact with a reference surface; an arm piece extending from the second end portion; and a linear light source disposed on a reference surface-facing side face of the arm piece, the light emitted by the linear light source producing a reference light beam on the reference surface and a direct light beam on an outer surface of the main body with one edge of the outer surface being adjacent to the reference surface; and a mobile unit comprising; a moving module; an image-capturing module for capturing an image of the reference light beam, the direct light beam, and a reflected light beam generated by the direct light beam striking the reference surface; and a computing module connected to the moving module and the image-capturing module for obtaining a reference angle formed between the reference light beam and the reflected light beam shown in the image, so as to obtain a relative angle between the mobile unit and the linear light source such that the mobile unit being guided for motion by the computing module based on the relative angle. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
