Abstract
An input apparatus includes a coordinate detector that detects position coordinates of an input on an input screen by an input tool, an image-capturing device that captures an image of a marker disposed on the input tool and indicating information on an attribute of the input tool, an input-tool identifier that identifies the attribute on the basis of the image of the marker captured by the image-capturing device, and an input-data generator that generates input data of the input tool on the basis of the position coordinates detected by the coordinate detector and the attribute identified by the input-tool identifier.
Claims20
An input apparatus including an input screen that receives an input on the input screen by an input tool, the input apparatus comprising:
- a coordinate detector that detects position coordinates on the input screen receiving an input by the input tool;
- an image-capturing device that captures an image of a marker disposed on the input tool, the marker indicating information on an attribute of the input tool;
- an input-tool identifier that identifies the attribute based on the image of the marker captured by the image-capturing device;
- and
- an input-data generator that generates input data of the input tool based on the position coordinates detected by the coordinate detector and the attribute identified by the input-tool identifier.
An input system including an input tool and an input apparatus that has an input screen for receiving an input on the input screen by the input tool, the input system comprising:
- a coordinate detector that detects position coordinates on the input screen receiving an input by the input tool;
- an image-capturing device that captures an image of a marker disposed on the input tool, the marker indicating information on an attribute of the input tool;
- an input-tool identifier that identifies the attribute based on the image of the marker captured by the image-capturing device;
- and
- an input-data generator that generates input data of the input tool based on the position coordinates detected by the coordinate detector and the attribute identified by the input-tool identifier.
