Problems solved by technology

Among them, some applications that come with the Android system use sensors such as acceleration sensors, brightness sensors, and proximity sensors. If the system supports them, users can install third-party software or write applications by themselves to experience the functions and fun brought by other sensors. , but installing third-party software or writing applications by yourself is cumbersome and costly

Abstract

The invention provides an input subsystem enabling the Android to support various sensors. The input subsystem is positioned on a kernel drive layer of the Android and comprises a device drive layer module, a core layer module and an event handling layer module. The device drive layer module comprises a sensor drive unit, and the sensor drive unit drives sensors to acquire signals, then reports values and type information of the signals to the core layer module and is responsible for configuring an abstraction input device module. The core layer module is used for converting the signal information reported by the sensor drive unit into input events recognizable to the Android and forwarding the input events to the abstraction input device module for storage. The event handling layer module is used for providing a hardware abstraction layer of the Android with an interface for accessing to the abstraction input device module. By the aid of the input subsystem, the Android can support various sensors so that users can experience functions and enjoyment brought by various sensors.

Description

【Technical field】 [0001] The invention relates to the technical field of communication equipment, in particular to an input subsystem that supports various sensors on an Android system. 【Background technique】 [0002] Android (Android) is the name of an open source mobile operating system based on the Linux platform released by Google, which is mainly used in portable electronic devices such as mobile phones, e-books, and tablet computers. Android is currently the most popular smartphone operating system. According to statistics in November 2011, Android occupies about 52.5% of the global smartphone operating system market, and its market share in China is as high as 58%. [0003] A sensor is a device or device that can sense a specified measured object and convert it into a usable signal according to certain rules, usually consisting of a sensitive element and a conversion element. One or two or more sensors are usually integrated in current smart phones to provide users w...
