Embodiment Construction

[0032] At present, most of the display screens or touch screens use capacitive screens and resistive screens to obtain the input trajectory of the input object on the screen, but as the production size of the capacitive touch panel becomes larger, the production cost is increasing. Large, and the extent of its production cost increase is also increasing.

[0033] In view of the problem that the screen input device in the prior art has a large production cost and is inconvenient to be widely used on large-size screens, an embodiment of the present invention provides a screen input system. The screen input system includes: a screen input device and processing Device. The screen input device may include: at least two image acquisition units, at least three light-emitting sources, and a control unit. Because only a few image acquisition units and light-emitting sources are used instead of a whole touch panel structure, screen input can be realized, so the production cost can be effe...

Abstract

The invention provides a screen input system. The system includes: a screen input device and a processing device. The screen input device includes: at least two image acquisition units, at least three light sources and a control unit. The moving trajectory of one of the light emitting sources corresponds to the input trajectory of the input object in the screen operation area; except for the one of the light emitting sources, other light emitting sources and the image acquisition unit are distributed around the screen; the image The acquisition unit is adapted to acquire the relative position image of the light source; the control unit is adapted to activate the light source distributed around the screen and the image acquisition unit when the preset condition is satisfied; the processing device is electrically It is connected to the image acquisition unit and is suitable for positioning the absolute position of the other light source in the screen operation area. The above-mentioned system can reduce the production cost of the screen input device, so as to be widely used on large-size screens.

Description

Technical field [0001] The invention relates to the field of information interaction, in particular to a screen input system. Background technique [0002] Input equipment is a device that inputs data and information to the information processing system. It is one of the main devices for information exchange between the information processing system and people or other external objects. The information processing system can receive a variety of data, either numerical data or non-numerical data, such as graphics, images, sounds, etc., which can be input to information processing through different types of input devices In the system, storage, processing and output are performed. [0003] At present, a screen input device such as a capacitive touch panel is used on a display screen or a touch screen. However, as the manufacturing size of the capacitive touch panel becomes larger, the manufacturing cost and the magnitude of increase thereof are greater. Summary of the invention [00...
