Abstract
An inclination detection method is disclosed, which uses a pair of electrodes placed so as to face each other and having a fixed positional relation and an electric conductor which can move between the pair of electrodes, wherein the pair of electrodes is in either a conducting state or a nonconducting state depending on the position of the movable electric conductor, the conducting state in a predetermined period is expressed as any one of a plurality of level values, and a movement state of the pair of electrodes is estimated based on which of the plurality of level values the conducting state takes on.
Claims13
A method comprising:
- an inclination detection apparatus comprising a pair of electrodes placed so as to face each other and having a fixed positional relation and a movable spherical electric conductor which can move between the pair of electrodes, wherein
- the pair of electrodes is in either a conducting state or a nonconducting state depending on the position of the movable spherical electric conductor,
- the conducting state in a predetermined period is expressed as any one of a plurality of level values, and
- a movement state of the pair of electrodes is estimated based on which of the plurality of level values the conducting state takes on;
- wherein movement state data which relates a change in the plurality of level values to a change in a movement of the pair of electrodes is prepared, and
- a movement of a body provided with the pair of electrodes and the movable spherical electric conductor is estimated by comparing a detection result of a change in the plurality of level values corresponding to the plurality of periods with the movement state data.
