Abstract

The invention discloses a large screen interaction method based on a handheld device, belonging to the field of human-computer interaction. The method comprises the following steps of: (1) establishing a connection between a server and a client side, and configuring and sending the number of large screen grids to the server by the client side; (2) after a large screen is divided by the server, sending a code of a grid where a cursor is located currently to the client side, and initializing an interactive interface by the client side; (3) moving the client side, and sending an image collected in real time to the server; (4) estimating the displacement of the client side by the server, and mapping the displacement of the client side into motion of the cursor on the large screen; (5) after the client side is moved to ensure that the cursor of the large screen is located to a certain grid region, switching the interactive interface to the current grid region of the large screen by the client side, controlling the interactive interface of the client side and sending the input control information to the server; and (6) carrying out interaction operation by the server in the current grid range of the large screen according to the control information. The large screen interaction method has the characteristics of strong interactivity, low cost, easiness for operation and the like.

Description

technical field [0001] The invention belongs to the field of human-computer interaction, and in particular relates to a large-screen interaction method based on a handheld device. Background technique [0002] Large-screen display devices appear more and more in public places such as modern offices and conferences, and their applications are becoming more and more extensive. For example, large-screen displays and conference projections are typical large screens. However, the interaction methods between computer systems for large-screen display are not rich enough. The most common interactive devices are traditional devices such as mouse and keyboard, while the large screen usually has a certain space distance from the user, and the user cannot leave the interactive input. equipment; in addition, some large-screen display devices support direct touch screen operations (such as Microsoft's surface), but due to the large display area, users cannot easily manipulate the entire l...
