Abstract

The invention discloses a mobile terminal and an interactive projection method and system of the mobile terminal, and belongs to the technical field of mobile terminals. The interactive projection method is applied to the mobile terminals. The method includes the steps that a mobile terminal obtains a preview image projected on a projection display device through the mobile terminal; the obtained preview image and a screen of the mobile terminal are made to form a coordinate mapping; when the mobile terminal acquires a light spot projected on the display device, the mapping coordinate of the screen corresponding to the coordinate of the light spot is inquired; the operation item corresponding to the position of the inquired mapping coordinate on the screen of the mobile terminal is executed. Through the mobile terminal and the interactive projection method and system of the mobile terminal, a user can not only conduct projection through the mobile terminal, but also can monitor display of the screen of the mobile terminal through operating frame of the projection, and therefore, display of the projection frame is changed, and the defects of high cost and inconvenience in carrying caused by the using of a special infrared camera are overcome.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a mobile terminal and an interactive projection method and system thereof. Background technique [0002] With the continuous development of smart phones in display technology and camera technology. Existing technology has been able to project the display content of the smart phone screen to other large-screen display devices, such as wifi display, MHL and other technologies. By manipulating the input device of the smart phone, a good audio-visual entertainment experience can be obtained. [0003] However, the user cannot control the projected large-screen display device. For example, an application in a smart phone is projected on the large screen for display, and the application can only be controlled by touching the screen of the smart phone instead of directly touching the large screen. . Although there are mature applications of interactive projection in t...
