The invention discloses an information processing method, input device and electronic device. The method is applied to an input device. The input device communicates with an electronic device. The electronic device includes a display unit. The input device is used to form a track point on the display unit to control the electronic device to perform a first operation. The method includes: transmitting a first operation to the electronic device. an optical signal; receiving a second optical signal from the electronic device, the second optical signal being generated by the electronic device according to the first optical signal; and determining position information of a track point formed by the input device on the display unit according to the second optical signal. Therefore, in the present invention, the position information of the track point formed by the input device on the display unit can be determined by transmitting and receiving optical signals between the input device and the electronic device without attaching additional information to the surface of the display unit. electronic components, thus improving the thinness and integration of the display unit.
Description
technical field [0001] The present invention relates to the field of computer technology, and more specifically, the present invention relates to an information processing method, an input device and an electronic device. Background technique [0002] In recent years, electronic devices such as notebook computers, desktop computers, tablet computers (PADs), mobile phones, multimedia players, personal digital assistants (PDAs), and the like have grown in popularity. Usually, such electronic devices are integrated with a touch display unit (for example, a touch screen). The touch display unit can receive user input, so that the electronic device can complete various operations according to user requirements. Simply, users can directly perform gesture operations on the touch screen through finger movements. However, the finger input method has obvious deficiencies in the accuracy and delicacy of the operation. Therefore, more and more electronic devices support pen input. ...
