Embodiment Construction

[0020] In order to make those skilled in the art better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

[0021] A current electronic device is usually provided with a touch screen, and a user can realize human-computer interaction on the electronic device through the touch screen. In some scenarios, when the user inputs through the touch screen, there is a need to record and display the touch trace, for example, drawing and graffiti, meeting minutes, etc. through a stylus. However, due to the delay in the transmission of touch screen report points and software rendering and drawing, the track displayed on the screen is often out of sync with the current actual touch point in the process of recording the touch track, that is, the displayed track and the current act...

Abstract

The invention discloses a touch track updating method and device, electronic equipment and a storage medium, and the touch track updating method comprises the steps: when a touch track is updated according to a currently reported first touch event, determining a track curvature of a current time period based on a reported touch point of the current time period; based on the trajectory curvature, determining a compensation value for the predicted duration; based on the compensation value, adjusting the prediction time length; based on the reported touch points in the current time period, predicting the touch points in the predicted duration after the touch time corresponding to the first touch event; and updating a touch track according to the touch points in the first touch event and the touch points in the predicted duration. According to the method, the time length to be predicted can be adaptively adjusted in the process of predicting the subsequent report points according to the real report points so as to update the touch track, and the accuracy of updating the touch track is improved.

Description

technical field [0001] The present application relates to the technical field of electronic devices, and more particularly, to a method, device, electronic device, and storage medium for updating a touch track. Background technique [0002] With the rapid advancement of science and technology, most electronic devices are provided with touch screens for users to perform human-computer interaction. When a user uses an electronic device, it is usually necessary to record and display the touch trace when the user touches the screen. For example, a stylus is used to touch the touch screen to record notes, paintings, and other scenarios. In the related art, due to the delay of the touch screen report point, the track displayed on the screen observed by the user is not synchronized with the current actual touch point. Some electronic devices will predict the future report point according to the touch screen report point to compensate for the delay. However, the accuracy of traject...
