As shown in fig. 2, the light and shadow sand table interaction system further comprises an intelligent bracelet 7 and a user system supported in the intelligent bracelet 7, the intelligent bracelet 7 is connected to the host 2 in a wireless communication manner, wireless communication connection modes such as WiFi and bluetooth can be adopted, and data interaction between the intelligent bracelet 7 and the host 2 can be achieved. It is worth to say that the smart band 7 may be a smart band 7 that is provided by the user.
The user system is application software nested in the intelligent bracelet 7 and comprises a screen splitting unit, a point location acquisition unit, a range identification unit and an intercepting unit.
The screen splitting unit is used for respectively configuring the touch screen 71 in the smart bracelet 7 into a left screen 711 and a right screen 712, and the left screen 711 and the right screen 712 are equal in width and length, so that the purpose of equally dividing the touch screen 71 is achieved. It should be noted that the touch screen 71 in the smart band 7 is a capacitive screen, and when a user touches the touch screen 71 with a finger to perform a touch operation, the smart band 7 will release the sleep state so as to be used for performing the touch operation.
The point location acquiring unit is used for detecting a touch operation of a user on the left screen 711 and/or the right screen 712 to obtain an initial point location, and obtaining an end point location after the user continuously slides on the left screen 711 and/or the right screen 712 and leaves the left screen 711 and/or the right screen 712;
and the range identification unit is used for obtaining a sliding path of the user according to the initial point location and the end point location, comparing the sliding path with a preset path and outputting a corresponding control instruction to the host 2 according to a comparison result.
The sliding path of the user obtained according to the initial point location and the end point location can be divided into a forward sliding path, a backward sliding path, a forward overturning sliding path, a backward overturning sliding path, an amplifying sliding path and a reducing sliding path. And the corresponding preset paths are a preset forward path, a preset backward path, a preset forward turning path, a preset reverse turning sliding path, a preset zooming-in path and a preset zooming-out path.

After receiving the control command of the backward movement, the host 2 jumps the control display picture to the previous one and correspondingly displays the control display picture on the projection screen 6 through the projector 5.
As shown in fig. 4A, is a display of a forward flip slide path. A user simultaneously touches a left screen 711 and a right screen 712 in the smart bracelet 7 with two fingers, a point location obtaining unit simultaneously obtains a first initial point location and a second initial point location from the left screen 711 and the right screen 712, and respectively obtains a first ending point location and a second ending point location corresponding to the first initial point location and the second initial point location on the right screen 712 and the left screen 711 according to continuous sliding operation of the user, and further detects a sliding direction of a line locus after the line locus is formed by the first initial point location, the first ending point location and the second initial point location and the second ending point location; if the sliding direction is clockwise, setting the line track as a forward-turning sliding path, and after the sliding path is successfully matched with a preset forward-turning path, sending a forward-turning control instruction to the host 2 by the smart bracelet 7; the host 2 controls the display picture to be turned over in the forward direction after receiving the control instruction of turning over in the forward direction.
On the contrary, if the sliding direction is counterclockwise, the line track is set as a reverse-turning sliding path, and after the sliding path is successfully matched with the preset reverse-turning path, the smart bracelet 7 sends a reverse-turning control instruction to the host 2; the host 2 controls the display picture to be reversely turned after receiving the control instruction of the reverse turning. As shown in fig. 4B.

As shown in fig. 6, the capture unit is used to define a capture area in the display picture, and to enlarge and display the capture area. The intercepting units are nested into a cross section, when the smart band 7 enters the intercepting interface, the touch screen 71 of the smart band 7 is not divided into a left screen 711 and a right screen 712, and when a user touches and clicks on the touch screen 71, a mark point appears at a corresponding position in the display picture.
