Abstract

The invention discloses a method for detecting an input device and a detection device. The method includes: acquiring the electric field strength of the electric field of the sending electrode of the input device at each detection electrode in the plurality of detection electrodes; The position of the center of gravity of the electric field and the center of the electric field; the attitude and / or position information of the input device is determined according to the position of the center of gravity of the electric field and the center of the electric field. The method for detecting an input device and the detection device in the embodiments of the present invention can reduce power consumption.

Description

technical field [0001] The present invention relates to the field of information technology, and more particularly, to a method for detecting an input device and a detection device. Background technique [0002] At present, multi-functional 2-in-1 ultrabooks are increasingly favored by consumers. Active capacitive pens, as the main peripheral input accessories of ultrabooks, are gradually attracting the attention of the market. At present, the market for active capacitive products is also showing prosperity. As a result, each company is trying its best to launch products with differentiated functions, among which pen posture detection is the leader in differentiated functions. [0003] Ordinary active capacitive pens transmit signals through the tip of the pen, and a certain number of horizontal detection electrodes and vertical detection electrodes are distributed on the touch plane, so the detection electrodes can be used to detect the signals emitted from the pen tip . ...
