Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Linear acceleration describes the physical quantity of the magnitude and direction of the linear velocity of a rigid body versus time. Its symbol unit in the international system of units is m / s^2 (meters per second). The biggest difference between a linear acceleration sensor and an acceleration sensor is: an acceleration sensor The obtained value includes the value of the gravitational acceleration caused by the earth's gravity, but the linear acceleration does not include the gravitational acceleration, because the interference of the gravitational acceleration is excluded, and the application of the linear acceleration sensor is more effective than the acceleration sensor in some occasions.

[0029] Such as figure 1 As shown, the present invention provides a human-computer interaction detection and processing method based o...

Abstract

The present invention relates to a man machine interaction detection and processing method based on a linear acceleration sensor in a smart terminal. It includes: (1) establishing a 3D coordinate system on a smart terminal, the X axis direction being from left to right horizontally, the Y axis direction being from bottom to top vertically, and the Z axis direction being from back to front and perpendicular to the screen of the smart terminal; (2) if the holder of the smart terminal takes an action, testing the linear acceleration of a terminal device in three axes of XYZ with a linear acceleration sensor respectively; (3) sampling the linear accelerations to respectively obtain variation curves of the linear acceleration vs. time in three directions of X axis, Y axis and Z axis; and (4) judging the action taken by the smart terminal according to the waveform diagrams of the variation curves of the linear acceleration vs. time in three directions of X axis, Y axis and Z axis and triggering a corresponding event according to the settings.

Description

Technical field: [0001] The invention relates to the field of communication, in particular to a human-computer interaction detection and processing method based on a linear acceleration sensor on an intelligent terminal. Background technique: [0002] Smart terminals are the current development trend of terminals. The smart terminal has an operating system and integrates various sensors, such as linear acceleration sensors, etc. The operating system on the smart terminal provides an operating environment for the application program, coordinates the resources required for the terminal to run, and completes the corresponding functions of the terminal. There are many applications running on the smart terminal, and these applications need to accept human-computer interaction to trigger the execution of control subroutines. [0003] At present, the human-computer interaction mode of the application program on the smart terminal is mainly to trigger the corresponding event by pre...
