Dual layer cursor clicking interaction method oriented to large-screen display device

Abstract

The present invention discloses a dual layer cursor clicking interaction method oriented to a large-screen display device. The method comprises the steps that 1) when initializing a large-screen interaction interface, a server end creates an outer layer cursor; 2) an interaction device sends motion information acquired by a sensor to the server end and controls the outer layer cursor to move on a large screen; 3) after the outer layer cursor moves to a target region, cursor control switching information is generated by touching a screen of the interaction device and sent to the server end, and the server end generates an inner layer cursor in a boundary region of the outer layer cursor, wherein a moving range of the inner layer cursor is defined within a range of the boundary region of the outer layer cursor; and 4) the interaction device sends touch mobile information on the screen of the interaction device to the server end and controls the inner layer cursor to move on the large screen, and after moving to a to-be-selected target, confirmation is performed in a set manner. The method disclosed by the present invention is capable of effectively balancing accuracy and speed in the long-distance large-screen target selection problem.

Description

technical field [0001] The invention belongs to the field of human-computer interaction, and in particular relates to a double-layer cursor selection interaction method for large-screen display devices. Background technique [0002] In recent years, with the development of technology, large-format, high-resolution display devices have become more and more common in our daily work and life. In group work represented by design planning and decision visualization, large-screen display devices are even more unavailable. missing facilities. The large-format feature of the large-screen display device enables it to present the panorama of objects such as two-dimensional images and three-dimensional graphics at one time, and the high-resolution feature enables it to present more local details at the same time, but on the other hand, the large-format, high-resolution The characteristics of the resolution increase the difficulty for people to click on a specific target on the display...

AI Technical Summary

Problems solved by technology

The first type of technology uses the camera of the smartphone to track and locate the target, and then projects the target on the screen of the mobile phone for subsequent operations. The second type of technology uses special equipment such as infrared laser pointers, 3D mice, and head trackers to directly select targets. This interactive method is easily affected by problems such as vibration and occlusion, and requires high equipment accuracy and operating distance. , and the price is high, it is not easy to promote

The third type of technology tries to use a handheld mobile device as an interactive device. The problem with this method is that when the control display gain is large, using the touch screen for long-distance sports requires repeated clutches to use fingers on the small screen. The short-distance movement of the control pointer moves long-distance on the large screen, resulting in low stability and efficiency

[0005] In addition, in the above-mentioned technologies, the operation command for selecting the target is often triggered by delay or special device, which increases the completion time of the target selection task and increases the learning cost of the user.

[0006] Another disadvantage of the above methods is that none of them involves the problem of multi-user collaborative operation
