Description

An interactive transparent display cabinet and an exhibit content control method thereof

Technical Field

The present invention relates to the field of display cabinets, and in particular to an interactive transparent display cabinet and an exhibit content control method thereof.

Background Art

With the increase of various exhibitions, the use of display cabinets is becoming more and more extensive. For example, in places such as sales offices or museums, sand tables are often needed to display regional features. The traditional way of explanation is that the lecturer uses a physical pointer or an electronic indicator (laser pen) to indicate the focus position of the current explanation, but this method has defects.

First, when the scale and three-dimensional fluctuations of the sand table are large, there are blind spots that cannot be indicated by the higher three-dimensional model from the side, whether through the pointer or the laser pen; secondly, the tour guide can only give a static explanation of the fixed sand table or cultural relics, and the content of the explanation can only be explained in a limited way through the tour guide's language description. The content presented is only a static sand table or cultural relics, which is single and cannot bring users a deeper understanding; finally, when the tour guide is explaining, it is impossible to display each scene element (such as real estate data, real-life photos, historical evolution, etc.) in real time with the tour guide's explanation content, so it cannot play a role in supplementing the introduction or setting off the target theme. It can be seen that the current showcase cannot bring users a multi-dimensional and deeper experience.

When the sliding tangent angle is greater than the second preset value, and the sliding tangent angle of the finger's final position is greater than 3 times the sliding tangent angle of the finger's initial position, the finger sliding type is determined to be finger rotation sliding; the second preset value ranges from 25° to 60°, including 25° and 60°.

If the finger moves in the vertical direction a, it is determined that during the vertical movement of the finger a, when the tangent angle a between the current frame position and the previous frame position of the finger is less than a first preset value, it is determined that the spotlight is sliding horizontally, and then the translation amount of the spotlight sliding is calculated according to the coordinates of the final position a2 and the coordinates of the initial position a1. At the same time, according to the coordinates of the final position a2 of the finger and the coordinates of the initial position a1, it is determined that the finger sliding is a downward vertical sliding. Then, the position coordinates of the spotlight on the top plate are consistent with the position coordinates of the finger on the sliding area interface A, and the movement direction is a downward vertical sliding.

At the same time, according to the coordinates of the final position c2 of the finger and the coordinates of the initial position c1, it is determined that the finger sliding is a rotational downward slide, then the pitch angle of the spotlight on the top plate increases, otherwise, the pitch angle decreases.

For example, if the finger makes a horizontal rotation movement d, and it is determined that during the horizontal rotation movement d, the tangent angle a of the finger sliding between the current frame position and the previous frame position is greater than the second preset value, and the sliding tangent angle of the finger at the final position d2 is greater than 3 times the sliding tangent angle of the finger at the initial position d1, it is determined that the spotlight is rotating and sliding, and then the rotation amount of the spotlight sliding is calculated according to the coordinates of the final position d2 and the coordinates of the initial position d1. At the same time, according to the coordinates of the final position d2 of the finger and the coordinates of the initial position d1, it is determined that the finger sliding is a rotational slide to the left, then the azimuth angle of the spotlight on the top plate increases, otherwise, the pitch angle decreases.
