Abstract

The invention discloses an information processing method and electronic equipment, wherein the method includes: controlling an image acquisition unit of the electronic equipment to perform image acquisition on the i-th writing equipment among the M writing equipment at the i-th acquisition frequency, and obtaining The first collection of images, i is an integer greater than or equal to 1 and less than or equal to M, the i-th acquisition frequency is less than the image acquisition frequency of the image acquisition unit, and M is an integer greater than or equal to 2; the image acquisition unit is controlled to The j-th collection frequency performs image collection on the j-th writing device among the M writing devices to obtain a second collection of images, where j is different from i and is an integer greater than or equal to 1 and less than or equal to M; according to the Determine the first position of the i-th writing device with the i-th collection frequency and the first collection of images; determine the j-th writing device according to the j-th collection frequency and the second collection image set the second position of .

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an information processing method and electronic equipment. Background technique [0002] With the development of human-computer interaction technology, more and more electronic devices such as tablet computers and smart phones are equipped with stylus pens, which record the trajectory of the pen through various methods, and then recognize it as text or graphics. While ensuring the multi-functionality of electronic equipment, it also greatly facilitates people who do not like to use keyboards or Chinese input methods. [0003] In the prior art, an infrared camera can be used in conjunction with a pen capable of emitting infrared light to realize the function of handwriting input for both the projected picture and the display area of ​​the display screen. [0004] In the process of implementing the technical solutions in the embodiments of the present application, the inventor...
