Abstract

The present invention discloses a method of detecting an input device and a detection device. The method comprises the steps of obtaining the electric field intensity of an electric field of a sending electrode of the input device at each of a plurality of detection electrodes; according to the electric field intensity of the electric field of the sending electrode at each of a plurality of detection electrodes, determining the gravity center position of the electric field and the central position of the electric field; according to the gravity center position of the electric field and the central position of the electric field, determining the information of the posture and / or position of the input device. According to the method of detecting the input device and the detection device of the embodiment of the present invention, the power consumption can be reduced.

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 . ...
