In some embodiments of the present invention, the terminal 1000 device can be various devices capable of acquiring and processing data from the outside, or the terminal 1000 device can be various devices which have a battery built therein and can acquire current from the outside to charge the battery, such as a mobile phone, a tablet computer, a computing device or an information display device.
In addition, terminal 1000 can also include attitude sensors, light sensors, and other sensors.
Specifically, the attitude sensor may also be referred to as a motion sensor, and as one of the motion sensors, a gravity sensor may be cited, which uses an elastic sensing element to make a cantilever type displacer and uses an energy storage spring made of the elastic sensing element to drive an electrical contact, thereby realizing conversion of a change in gravity into a change in an electrical signal.
Another example of the motion sensor is an accelerometer sensor, which can detect the magnitude of acceleration in each direction (generally, three axes), detect the magnitude and direction of gravity when stationary, and can be used for applications for recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like.
In the embodiment of the present invention, the motion sensor listed above may be used as an element for obtaining the "attitude parameter" described later, but the present invention is not limited thereto, and other sensors capable of obtaining the "attitude parameter" fall within the protection scope of the present invention, for example, a gyroscope, etc., and the operation principle and the data processing procedure of the gyroscope may be similar to those of the prior art, and the detailed description thereof is omitted here for avoiding redundancy.
In addition, in the embodiment of the present invention, as the sensor, other sensors such as a barometer, a hygrometer, a thermometer, and an infrared sensor may be further configured, which are not described herein again.
In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Moreover, various embodiments or examples and features of various embodiments or examples described in this specification can be combined and combined by one skilled in the art without being mutually inconsistent.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present invention.
