Abstract
An input apparatus including an optical mouse module and a mouse pad module is provided. The optical mouse module includes a light source and an optical sensor. The light source is adapted to emit a light beam. The optical sensor has a sensible distance. The mouse pad module is disposed on the optical mouse module. The mouse pad module includes a sliding sheet elastically coupled to the optical mouse module. The sliding sheet is adapted to move in a three-dimensional space. The optical sensor and the sliding sheet are arranged in an arrangement direction. An operation method of the input apparatus is also provided.
Claims14
An input apparatus, comprising:
- an optical mouse module, comprising a light source and an optical sensor, wherein the light source is adapted to emit a light beam, and the optical sensor has a sensible distance;
- and
- a mouse pad module, disposed on the optical mouse module, the mouse pad module comprising a sliding sheet elastically coupled to the optical mouse module, wherein the sliding sheet is adapted to move in a three-dimensional space, the optical sensor and the sliding sheet are arranged along an arrangement direction, when the sliding sheet is pressed to enter within the sensible distance of the optical sensor and moves along a direction perpendicular to the arrangement direction, the sliding sheet reflects the light beam to the optical sensor, so that the optical sensor senses a movement of the sliding sheet relative to the optical mouse module along a direction perpendicular to the arrangement direction, and when the sliding sheet is not pressed, an elastic force formed by coupling the sliding sheet to the optical mouse module rebounds the sliding sheet back to outside of the sensible distance, so that the optical sensor is unable to sense a movement of the sliding sheet relative to the optical mouse module along the direction perpendicular to the arrangement direction.
An operation method of an input apparatus, the input apparatus comprising an optical mouse module and a mouse pad module, the optical mouse module comprising a light source and an optical sensor, the optical sensor having a sensible distance, the mouse pad module being disposed on the optical mouse module, the mouse pad module comprising a sliding sheet elastically coupled to the optical mouse module, and the optical sensor and the sliding sheet being arranged along an arrangement direction, the operation method of the input apparatus comprising:
- pressing the sliding sheet to enter within the sensible distance of the optical sensor by a first finger;
- pushing the sliding sheet along a direction perpendicular to the arrangement direction by the first finger;
- and
- leaving the first finger from the sliding sheet or letting a pressing force of the first finger to the sliding sheet to be less than an elastic restoring force formed by coupling the sliding sheet to the optical mouse module, so that the sliding sheet is rebounded back to outside of the sensible distance due to the elastic force formed by coupling the sliding sheet to the optical mouse module.
