Abstract
An information output device that can output the position of a load applied to the pedal is provided. A strain gauge is provided on the inner face of a crank of a bicycle and detects strain occurring in the crank. A cycle computer display unit displays an image showing the center position of the load applied to the pedal connected to the crank based on the tangential force and the torsional torque calculated based on the output values of the first strain gauge to the sixth strain gauge.
Claims5
An information output apparatus comprising:
- a strain detection device provided on a crank in a human-powered machine, and configured to detect a strain occurring in the crank;
- and
- an output device configured to display a load applied to a pedal connected to the crank and a position of the load applied on the pedal, based on an output value of the strain detection device,
- wherein the output device displays a center position of the load applied on the pedal and a center position of a load as a reference in a manner comparable with each other,
- wherein the position of the load applied on the pedal is displayed based on a first force in a first direction that causes torsion in the crank, and a second force in a second direction that is on a circle defined by a rotational motion of the crank, and
- wherein the strain detection device has a plurality of strain gauge parts including:
- a first strain gauge part configured to detect a strain deforming in the first direction in the crank;
- and
- a second strain gauge part configured to detect a strain deforming in the second direction in the crank.
A non-transitory computer-readable medium including at least one processor and a storage that are configured to execute instructions, the instructions comprising:
- receiving information from a strain detection device provided on a crank in a human-powered machine;
- providing an instruction to detect a strain occurring in the crank based on the received information;
- and
- displaying a load applied to a pedal connected to the crank and a position of the load applied on the pedal via an output device, based on an output value of the strain detection device,
- wherein the instructions further comprise displaying a center position of the load applied on the pedal and a center position of a load as a reference in a manner comparable with each other,
- wherein the displaying comprises displaying the position of the load applied on the pedal based on a first force in a first direction that causes torsion in the crank, and a second force in a second direction that is on a circle defined by a rotational motion of the crank, and
- wherein the strain detection device has a plurality of strain gauge parts including:
- a first strain gauge part configured to detect a strain deforming in the first direction in the crank;
- and
- a second strain gauge part configured to detect a strain deforming in the second direction in the crank.
