Calling method and device for orientation sensors of handheld mobile equipment

Abstract

The invention relates to the technical field of handheld mobile devices, in particular to a calling method for orientation sensors of handheld mobile equipment. According to the method, when applications requiring calling of the orientation sensors are first-type applications, gyroscopes are turned off, orientation information, instead of angular motion information, is obtained, and only basic direction indication requirements are met, so that the reaction speed of the equipment is improved, and direction indication effects can be rapidly obtained by the first-type applications. When the applications calling the orientation sensors are not the first-type applications, the gyroscopes are not turned off, and the angular motion information of the gyroscopes is obtained, so that screen effects during rotation of the equipment are improved according to the angular motion information of the gyroscopes, and screens are smooth. Accordingly, different calling methods are used for different gyroscope sensors on account of different applications, relevant sensing data can be obtained by each application according to characteristics of the application, operation effects of the applications are in accordance with user requests, and the user experience is effectively improved.

Description

technical field [0001] The invention relates to the technical field of handheld mobile devices, in particular to a method for invoking an orientation sensor of a handheld mobile device. The method is accomplished by establishing a functional module framework and controlling the computer system by computer program instructions. Background technique [0002] Handheld mobile devices (such as smart phones) generally have multiple orientation sensors. When the application software on the device needs to perform operations such as orientation information collection, it will call these sensors and collect the sensory information of these sensors, and perform integration based on these sensory information. , differential, etc. to calculate the required data and make use of it. [0003] Generally speaking, magnetic sensors and acceleration sensors are essential orientation sensors for handheld mobile devices. When users open applications that need to obtain relevant orientation inf...

Problems solved by technology

However, in the presence of a gyroscope in an existing handheld mobile device, no matter what type of application it needs to obtain orientation information, it will call the gyroscope sensor, magnetic sensor and acceleration sensor at the same time, that is, the handheld mobile device needs to obtain The call to the gyroscope for orientation information is determined based on hardware conditions, and a specific call method cannot be used for a specific application, resulting in poor user experience. For example, when the user opens a compass-type application, the application also calls the gyroscope sensor , magnetic sensor and acceleration sensor and start the nine-axis algorithm to obtain a smooth rotating screen. However, for the user at this time, the response of the application is slow, and the effect of the guide (direction indication) cannot be achieved quickly, which fails to meet the most practical needs of the user.
