Problems solved by technology

[0009] Therefore, in order to solve the above problems, the present invention provides a positioning device and its method capable of switching between the active working mode and the passive working mode according to different needs, which are used for motion sensing and handwriting recording in mobile devices. Switch to the active working mode for accurate handwriting tracking and recognition, use a special pen for handwriting tracking and some interactive control, and switch to the passive working mode when it is inconvenient to use the pen, and directly use your fingers to complete some tasks that require less precision interactions such as zooming, media playback controls, dragging, etc.

Embodiment Construction

[0046] Exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Here, it should be noted that, in the drawings, the same reference numerals are assigned to components having substantially the same structure and function, and redundant descriptions on components that are substantially the same are omitted in order to make the description more concise.

[0047] The positioning device according to the present invention uses a set of signal receivers to support the active mode and the passive mode, and can switch the working mode among the active mode, the passive mode, and the hybrid mode.

[0048] Among them, when the passive mode ultrasonic / infrared signal source is turned on, gestures and actions can be detected directly without additional equipment; when the passive mode ultrasonic / infrared signal source is turned off, the same set of signal receivers can be used to detect pen (Hereinafter also ref...

Abstract

The invention provides positioning equipment and a positioning method thereof. The positioning equipment comprises at least one signal receiver, an active signal processing unit and a passive signal processing unit, wherein the signal receiver is used for receiving an active signal transmitted by a target indicator and/or a passive signal reflected by a target object and transmitted by a passive signal emitter; the active signal processing unit is used for processing a positioning signal based on the active signal to generate first positioning data; and the passive signal processing unit is used for processing a positioning signal based on the passive signal to generate second positioning data.

Description

technical field [0001] The present invention relates to the man-machine interface technology in the mobile device, and more specifically, to the positioning device and the positioning method thereof in the mobile device. Background technique [0002] With the development of mobile communication technology, multimedia content is increasingly rich, coupled with the demand for mouse click and gesture control in Internet applications, handheld devices show a trend of using large-size screens and touch screens. However, for the scheme of using the screen as the operation control area, there are problems such as the operation area is limited by the size of the screen, and the screen is blocked during operation. [0003] People are accustomed to using paper and pen to record meetings, daily records, notes, etc., but they also hope to store, archive, organize, etc. on digital devices, and hope that the recorded content can be integrated with sound, video, etc. etc. record synchroni...
