In related technologies, these electronic products can not only present images of 3D objects to users, but also allow users to touch the screen with their fingers and make 3D gestures in the air away from the touch screen to control the movement or deformation of the 3D objects displayed on the screen. However, this technology needs to use a distance sensor to sense the distance from the projection of each finger corresponding to the user's 3D gesture in the air to the corresponding point on the screen. However, the more fingers are used, the more difficult it is to accurately detect the position of each finger, and the number of sensors will increase accordingly, which will increase the cost of the product and is not conducive to the development of products in the direction of lightness and thinness.

In addition, due to the space limitation between the distance sensor and the 3D gesture in the air, only simple 3D object graphics can be made on the touch screen, and the length of the object will be obviously limited; and the farther the distance sensor senses, the greater the error, so , users cannot create complex 3D objects as they wish without repeated trials and experiments.

The electronic device 10 includes a touch screen module 100 and a processor 200 . Referring to FIG. 2 , the touch screen module 100 includes a touch screen 101 , a touch sensor 104 and a pressure sensor 105 electrically connected to the touch screen 101 .

The touch sensor 104 is used to sense a user touching the touch screen 101 and output a touch sensing signal to the processor 200 . The pressure sensor 105 is used to sense the pressure of the user's finger pressing the touch screen 101 , and output a pressure sensing signal to the processor 200 . The processor 200 is used for computing and executing programs for creating three-dimensional objects on the touch screen.

As shown in FIG. 3 , the processor 200 further includes a receiving unit 201 , a timing unit 202 , an object creation unit 203 , a gesture movement sensing unit 204 and a memory 206 . The receiving unit 201 is used to receive the touch sensing signal output by the touch sensor 104 and the pressure sensing signal output by the pressure sensor 105, and determine the position of the user's finger on the touch screen. The timing unit 202 is used to count the time the user's finger stays on the touch screen 101 . The object creating unit 203 is used for constructing an object with a certain shape according to the position of the user's finger on the touch screen 101 and the staying time. The gesture movement sensing unit 204 is used to sense the moving direction and distance of the user's finger on the touch screen, and transmit the sensed moving direction and distance information to the object creation unit 203, and the object creation unit 203 will The direction and distance information changes the shape of the object displayed on the touch screen 101 accordingly.

The memory 206 stores a color table of different colors corresponding to different time and pressure values. The pressure sensor 105 senses the pressure of the user pressing the touch screen 101 , and outputs the pressure to the object creation unit 203 of the processor 200 . The object creating unit 203 adjusts the color, line width or length of the object displayed on the touch screen 101 according to the received pressure, wherein the color of the object can be adjusted according to the color table stored in the memory 206 .

As shown in FIG. 4 , when a finger of the user draws a vertex A on the touch screen 101 , the object creating unit 203 constructs a two-dimensional object L with a straight side of the object according to the vertex A.

As shown in FIG. 5, when two fingers of the user draw two vertices A and B on the touch screen 101, the object creating unit 203 constructs the bottom edge A-B of the object according to the positions of the two vertices A and B, and The two vertices A and B extend outward to form two sides A-A` and B-B` perpendicular to the bottom A-B, wherein the longer the user's finger stays on the touch screen 101, the longer the two sides A-A` and B-B The length of ` is longer. In this way, a rectangular object 500 can be created.

As shown in Figure 6, when the user's three fingers draw three vertices C, D, E on the touch screen 101, the object creation unit 203 constructs the bottom surface C-D-E of the object according to the positions of the three vertices C, D, E, and The three vertices C, D, E are stretched outward to form a top surface C`-D`-E` parallel to the bottom surface C-D-E, wherein the longer the user's three fingers stay on the touch screen 101, The farther the top surface C`-D`-E` is from the bottom surface C-D-E, and there are several vertical lines between the bottom surface C-D-E and the top surface C`-D`-E` that are perpendicular to the bottom surface C-D-E and the top surface C`-D`-E` side. In this embodiment, the three vertices C, D, E touch the touch screen 101 at the same time, and the three vertices C′, D′, E′ of the top surface C′-D′-E′ leave the touch screen 101 at the same time. In this way, a regular triangular prism object 600 with three sides of the same size can be created.

As shown in Figure 7, when the user's three fingers draw three vertices 1, 2, 3 on the touch screen 101, the object creation unit 203 constructs a bottom surface 1-2- 3, and stretch the three vertices 1, 2, 3 of the bottom surface 1-2-3 outward to form a top surface 3`-2`-1`. Among them, the three vertices 1, 2, 3 of the bottom surface 1-2-3 correspond to the three vertices 3`, 2`, 1` of the top surface 3`-2`-1`, and the serial number represents The order of the fingers touching the touch screen 101 , the larger the sequence number, the later the order of touching the touch screen 101 . That is, in this embodiment, the vertex 1 of the bottom surface 1-2-3 touches the touch screen 101 the earliest and leaves the latest; the vertex 3 touches the touch screen 101 the latest and leaves the earliest. A number of sides perpendicular to the bottom surface 1-2-3 are formed between the bottom surface 1-2-3 and the top surface 3`-2`-1`, and the distance between the vertex 1 and the vertex 3` is greater than the distance between the vertex 2 and the vertex 2`, the distance between vertex 3 and vertex 1` is smaller than the distance between vertex 2 and vertex 2`. In this way, triangular prisms of any shape and size can be created. Of course, when the user's three fingers touch the touch screen 101 at the same time, but the three fingers leave at different times, the object creation unit 203 can also create a special 3D object 700 accordingly. As shown in FIG. 8 , when the user's three fingers move from opening to closing to converging on the touch screen 101 , a triangular cone-shaped object 800 can be created.

As shown in Figure 10, when the user draws a circle clockwise along the direction of number 1 on the touch screen 101 with one finger, and then moves the finger to both ends of the circle, a cylinder can be created according to the dwell time of the finger of number 2 Item 1000.

As shown in Figure 11, in one embodiment, in addition to using the residence time to control the extension length of the object, it can also be controlled by the pressure sensed by the pressure sensor 105. Time, pressure and the length of the object are in a relative relationship. It can be a linear or non-linear relationship, and the software designer can set it according to the needs. As shown in Figure 12, in one embodiment, the stretched length of the object can also be controlled by the time T, the edge width P can be controlled by the pressure or the color of the adjusted object can be changed; after the object is created, the finger can also stay on the Time on the object to change color. The relationship between color, color density and pressure can be preset in the memory 206 .

As shown in Figure 13, when the user's finger moves from any point 1 to any point 2 on the touch screen 101, the object can be detected by the gesture movement sensing unit 204, and the object is controlled to be dragged and moved to the direction of the finger Flip.

As shown in Figure 14, the object is flipped to the position to be modified by the control gesture, and the surface P to be modified is selected with a finger, and then the two fingers 1 and 2 are brought together to tap the screen once, and the object creation unit 203 can move the plane to be modified PZooms out to flat P´, increasing the degree of modification with the number of taps or the time between taps.

As shown in FIG. 15 , the object is flipped to the position to be modified by the control gesture, and the surface P to be modified is selected with a finger, and then the two fingers 1 and 2 are separated and tapped on the screen, and the object creation unit 203 can move the plane to be modified PZoom in to the plane P´´, and the degree of modification can be increased with the number of taps or the time between taps. When the object is not clicked, the overall size and zoom control of the object can be performed.
