[ detailed description ] embodiments
Referring to fig. 1A to 1B, fig. 1A is a schematic diagram illustrating an interactive display system 1000 according to an embodiment, and fig. 1B is a top view illustrating the interactive display system 1000 of fig. 1A. The interactive display system 1000 includes a rotating component 110, a manipulating component 120 and a display component 130. The rotating assembly 110 includes a fixing portion 111, a supporting body 112 and a rotating shaft 113. The fixing portion 111 is, for example, a fixing sleeve. The fixing portion 111 does not rotate. The carrier 112 is, for example, a plate structure, an arc structure, a ring structure, a semi-circle structure or a pillar structure. In the example of fig. 1A, carrier 112 is a flat plate structure. The rotation shaft 113 is connected to the carrier 112, and the rotation shaft 113 rotates relative to the fixing portion 111 to rotate the carrier 112.
The control assembly 120 includes an image capturing unit 121, a zero calibration unit 122, and an image analyzing unit 123. The image capturing unit 121 and the image analyzing unit 123 are, for example, a circuit, a chip, a circuit board, a plurality of sets of program codes, or a storage device for storing the program codes. The image capturing unit 121 is disposed on the carrier 112. The image capturing unit 121 rotates along with the carrier 112 and continuously captures a plurality of images IM. In the example of fig. 1, the image capturing unit 121 is disposed on a rotation center of the carrier 112 and rotates along with the rotation of the carrier 112.
The zero calibration unit 122 is configured to send a zero signal S0 when the carrier 112 rotates to a predetermined angle. That is, the zero point calibration unit 122 may send out the zero point signal S0 every time the carrier 112 makes one rotation to a predetermined angle. The zero signal S0 can be used as a stamp to allow the image analysis unit 123 to recognize the angle corresponding to each image IM. When the user waves the palm or finger in front of the image capturing unit 121, the image analyzing unit 123 can analyze the gesture from the continuously captured images IM.
In this way, the image analysis unit 123 can obtain a control signal S1 corresponding to the gesture according to the images IM and the zero signal S0.
The display device 130 is composed of a plurality of light emitting diodes 131. The display module 130 is connected to the carrier 112. The light emitting diodes 131 of the display module 130 rotate with the carrier 112. When the carrier 112 rotates rapidly, the user can see the leds 131 spread over the entire rotation range of the carrier 112 by the persistence of vision.
With the interactive display system 1000 of fig. 1, a user can intuitively operate the image displayed by the display assembly 130 above the interactive display system 1000, and during the operation, the user does not need to touch the carrier 112 or the display assembly 130, but only needs to compare the image in the air.
In another embodiment, the rotation component 110 and the steering component 120 can form a floating-in-the-air truncated-image type steering device. That is, in the case of no display device 130, the floating-in-the-air image-intercepting operation can be completed by the rotating device 110 and the operation device 120, and the operation device is suitable for operation situations such as bulletins or elevator panels.
Referring to fig. 2, a block diagram of a floating-in-the-air image-intercepting type control device 100 according to an embodiment is shown. The floating image-capturing control device 100 includes a rotation component 110, a control component 120, and a power supply component 140. The power supply assembly 140 drives the motor 114 to rotate the rotary shaft 113. The rotation frequency of the motor 114 may not be the same as the shooting frequency of the image capturing unit 121. For example, the motor 114 may rotate slowly when starting and may tend to stabilize after a period of operation. The image capturing unit 121 can capture images at a stable capturing rate. The zero point signal S0 provided by the zero point calibration unit 122 enables the image analysis unit 123 to identify the angle corresponding to each image IM. The zero calibration unit 122 includes a signal transmitter 1221 and a signal receiver 1222. As shown in fig. 1, the signal emitter 1221 is disposed on the fixing portion 111 (or on the carrier 112), for example. The signal transmitter 1221 is used to transmit a sensing signal e 1. The signal receiver 1222 is disposed on the fixing portion 111 (or the carrier 112), for example. A reflective material may be attached to the underside of carrier 112. When carrier 112 rotates to a predetermined angle, signal receiver 1222 can receive sensing signal e1 reflected from carrier 112 and output zero signal S0 accordingly.
Referring to fig. 3, the relationship between the zero signal S0 and the image IM is shown. The signal receiver 1222 receives the sensing signal e1 at time points T1-T7, …, respectively. When the motor 114 is started and the rotation speed is relatively slow, the signal receiver 1222 does not receive the sensing signal e1 until the time point T2 after receiving the sensing signal e1 at the time point T1. Each receipt of sense signal e1 indicates that carrier 112 has rotated one revolution. When the rotation speed of the motor 114 tends to be stable, the time interval during which the signal receiver 1222 receives the sensing signal e1 at the time points T4-T7, … is shortened. Each receipt of sense signal e1 indicates that carrier 112 has rotated one revolution. As can be seen from the correspondence relationship in fig. 3, the videos IM01, IM11, IM16, IM19, IM22, IM25, IM28, and … correspond to time points T1 to T7, and …, respectively. By means of the corresponding relationship, the angle corresponding to each image IM can be converted.
Even if the user accidentally touches the carrier 112 and changes the rotation speed of the carrier 112, the zero signal S0 is still emitted at a predetermined angle, so that each image IM can still correspond to the angle correctly. Therefore, the gesture of the floating operation of the user can be accurately identified. The operation of the above elements is described in detail with reference to the flow chart.
Referring to fig. 4, a flow chart of a floating control method according to an embodiment is shown. In step S110, the rotating shaft 113 of the rotating assembly 110 rotates to drive the carrier 112 and the image capturing unit 121 to rotate. The rotation of the image capturing unit 121 can rotate or revolve around a central axis.
Next, in step S120, the image capturing unit 121 captures a plurality of images IM continuously. The image capturing unit 121 can capture images with fixed resolution, size and brightness, so that the time required for capturing each image IM is substantially the same.
Then, in step S130, the zero point calibration unit 122 receives the zero point signal S0.
Next, in step S140, the image analysis unit 123 obtains a control signal S1 according to the images IM and the zero signal S0. In this step, the image analysis unit 123 converts the angle of each image IM from the zero point signal S0. The image analysis unit 123 performs appropriate processing according to the angle, such as rotation, cutting, overlapping, stitching, and selecting, to facilitate the determination of the gesture. After the image analysis unit 123 analyzes the gesture, it can analyze the control signal S1 (e.g., turning a page, sliding a page, rotating an object, etc.) corresponding to the gesture through a lookup table.
In addition to the above embodiments, the carrier 112 and the image capturing unit 121 may also take other embodiments.
