Embodiment Construction

[0115] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0116] In this embodiment, a method for detecting coordinates in a three-dimensional space includes:

[0117] The near-point distance and far-point distance of the pseudo-finger target are respectively measured by more than three groups of ultrasonic distance measuring devices that are not on the same straight line arranged around the mobile terminal, and the obtained near-point distance and far-point distance of more than three groups are used. The point distance, combined with the spatial coordinates of the corresponding ultrasonic distance measuring device, is calculated t...

Abstract

A detection method for three-dimensional space coordinates, a three-dimensional input method and corresponding devices. The detection method comprises: more than three groups of ultrasonic ranging devices which are not located on the same straight line and are arranged on the periphery of a mobile terminal respectively measuring a near-point distance and a far-point distance of a pseudo-finger target substance, and using the obtained more than three groups of near-point distances and far-point distances and combining with space coordinates of the corresponding ultrasonic ranging devices to calculate so as to obtain a calculation centre point coordinate of the pseudo-finger target substance. The three-dimensional input method comprises: when it is detected that a preset triggering action is triggered, more than three groups of ultrasonic ranging devices which are not located on the same straight line and are arranged on the periphery of a mobile terminal starting up to track and measure three-dimensional space coordinates of a pseudo-finger target substance, and displaying same to the mobile terminal correspondingly. By means of the embodiments of the present invention, a user can complete an input operation by hand without using other additional auxiliary electronic devices such as an additional remote controller, a writing pen or a finger stall, and thus the operation is more free and convenient.

Description

technical field [0001] The invention relates to an input device of a mobile terminal, in particular to a detection method of three-dimensional space coordinates, a three-dimensional input method and a corresponding device. Background technique [0002] As the personal portable electronic device of modern people, mobile terminal has various functions and outstanding performance, and it is a very good tool whether it is used for work or entertainment. Broadly speaking, mobile terminals include: mobile phones, notebooks, tablet computers, POS (Point Of Sale, sales terminal) machines and even vehicle-mounted computers, but in most cases it refers to mobile phones or smart phones and tablet computers with multiple application functions. As an essential function of a mobile terminal, the input function has a great impact on user experience. [0003] Most of the input methods of the mobile terminals currently on the market adopt plane input. Whether it is the input method of movi...
