[0019] To make the purpose, technical solutions and advantages of the present disclosure clearer, the following are examples for further detailed description of the present disclosure. It should be understood that the specific embodiments described here are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0020] In an exemplary embodiment, a device for non-contact operation of a device is disclosed herein. The device is not limited herein and can be a medical device or an industrial device such as a machine tool. The device includes a first sensor for sensing a first gesture operation for triggering the projection of a non-contact operation interface. If the non-contact operation interface is always projected in the air, on the one hand, it may cause trouble to the operator and interfere with the line of sight, and on the other hand, it is also prone to accidental touch. Therefore, when needed, the non-contact operation interface can be called up by the first gesture, and after use, the non-contact operation interface can be closed by the first gesture again. Of course, different third gestures can also be set to close the non-contact operation interface. The device further includes a first projection component for projecting a first interaction interface to a first spatial position, where the first interaction interface is the non-contact operation interface and the first spatial position is the position where the operator operates on the interface. This first spatial position can be specific or unspecific. For the case where the position is unspecific, for example, it can be the position where the first gesture is located. In this case, when the operator uses the first gesture to call up the non-contact operation interface, the hand is placed at a position convenient for operation, and the projection component projects the operation interface to this position, which is extremely convenient for the operator, especially when the operator needs to move to different positions for operation. Another option for the unspecific position is to automatically recognize the position and posture of the operator and automatically project it to a position convenient for operation, and this position can also change following the position and posture of the operator, always maintaining a position convenient for the operator. Further, the operator can also use a specific gesture to drag the operation interface to a more suitable position. The device further includes a second sensor for sensing a second gesture operation at the first spatial position. The operation interface often consists of virtual buttons or virtual knobs, etc., and the second gesture is the clicking, rotating, etc. of these virtual buttons or virtual knobs. The device further includes a switch circuit connected to the first sensor, the first projection component, and the second sensor. After receiving the signal from the first sensor, the first projection component is turned on to project the virtual operation interface, and at the same time, the second sensor is turned on to sense the operations on the virtual operation interface. The device further includes a power supply for supplying power to the first sensor, the first projection component, the second sensor, and the switch circuit. Of course, the device further includes a processor that can process the received second gesture operation and then transmit it to the device, thereby obtaining non-contact operation of the device. In this embodiment, the switch circuit can be a part of the processor, or rather, the processor has the function of the switch circuit, that is, when the processor receives the signal sensed by the first sensor for the first gesture operation, the first projection component and the second sensor are turned on.

[0021] In an exemplary embodiment, in order to adapt to displaying a virtual operation interface at different positions, the device may further include a second projection component for projecting a first interaction interface to a second spatial position, which is a position specified by the operator, and the specific specifying method is, for example, the spatial position where the user makes a first gesture. The device further includes a third sensor for sensing a second gesture operation at the second spatial position; a switch circuit is connected to the second projection component, and after receiving the signal of the first sensor, the second projection component and the third sensor are turned on. In this way, the operator can call up the virtual operation interface at different spatial positions without having to move to a specific position for operation. In this embodiment, multiple projection components are used to project the virtual operation interface to different positions. Optionally, the same set of projection devices can also be used to achieve this purpose, as long as this projection device can achieve this function, for example, it may have movable or rotatable components, or the range it can project is very large, and only a certain part of it is selected for imaging each time, as long as the function of projecting the virtual operation interface at different positions can be achieved.

[0022] In an exemplary embodiment, the first sensor is a touch sensor. The advantage of this kind of sensor is that it will be triggered only when the user touches it, which can greatly avoid accidental touches. However, correspondingly, this touch-triggered method will bring hygiene problems. Another option is an infrared proximity sensor, which can be triggered without contact, meeting the hygiene requirements. However, the infrared proximity sensor still needs to be operated at a specific position. Another option is a gesture recognition sensor. The gesture recognition sensor can use technologies such as TOF to sense all gestures within a certain spatial range. A first gesture is predefined, for example, waving the hand continuously 3 times, or holding the ok gesture for a specific time, as long as this gesture is not commonly used in the scenario of operating the device. The gesture recognition sensor method solves the hygiene and fixed-position problems.

[0023] In an exemplary embodiment, specifically referring to Figure 2 , the first projection component includes a high-brightness display screen 6 and a projection glass 5. The high-brightness display screen 6 and the projection glass 5 are arranged opposite to each other. Its image is first projected onto the projection glass 5, and then the projection virtual image 4 is projected to the first spatial position through the projection glass 5, and the projection virtual image 4 is the virtual operation interface. In this way, the projection glass 5 is between the display screen 6 and the first spatial position where the projection virtual image 4 is located.

[0024] In an exemplary embodiment, continuing to refer to Figure 2 , the second sensor is a gesture recognition sensor. The gesture recognition sensor projects an infrared light field 9 to the first spatial position. In this way, the gesture at the first spatial position will affect the infrared light field 9, thereby recognizing the gesture. The sensor is not limited to this. For example, an image sensor is also possible, or a 3D image sensor, a time-of-flight sensor (TOF).

[0025] In an exemplary embodiment, a device for non-contact operation of a device according to the present disclosure includes: a sensor for sensing a first gesture operation and for sensing a second gesture operation at a first spatial position; a projection component for projecting a first interaction interface to the first spatial position; a switch circuit connected to the sensor and the projection component, and for turning on the projection component after receiving a signal sensed by the sensor for the first gesture operation; and a power supply for supplying power to the sensor, the projection component, and the switch circuit. In this embodiment, the same sensor is used to sense the first gesture and the second gesture, without the need for multiple sensors. The first gesture is generally defined as a gesture that is not easily used in the scenario of operating a device, but is simple and easy to remember, such as waving the hand three times continuously at the same position, or making an "OK" gesture and holding it for a certain period of time, such as 1 second. In this embodiment, in one way, the virtual operation interface called up by the first gesture at any spatial position is at the position where the first gesture is made. In another way, the first gesture is made at a specific position, and the virtual operation interface called up is at another specific position, or at a position convenient for the operator to operate determined by computer vision recognition technology. In this embodiment, the sensor can be, for example, an image sensor, a 3D image sensor, or a time-of-flight sensor (TOF), and these sensors can all recognize specific gestures within a certain range. To solve the occlusion problem, multiple sensors can be provided to obtain information from different angles.

[0026] In an exemplary embodiment, taking the scenario of non-contact operation of a medical device as an example, a C-arm X-ray machine is often used in cardiovascular surgeries. To facilitate operation, many C-arm X-ray machines are equipped with a touch screen beside the hospital bed for device operation and display. During the surgery, the doctor's hands need to be disinfected. However, after the hands are disinfected, it is very inconvenient to operate the touch screen. On the one hand, the liquid (alcohol or blood) on the doctor's hands may dirty the screen and even cause misoperation. On the other hand, the doctor is also worried about the possibility of secondary contamination of the hands by touching the device. Moreover, the touch operation device beside the operating bed also takes up a lot of space and is prone to collide with the doctor, which will have a certain impact on the doctor's movement. To solve the above-mentioned problems, this embodiment adopts an air projection operation method to replace the traditional human-machine operation interface. This air operation interface integrates all button and image display functions. For details, see Figure 1, in the operating room, there is a hospital bed 1 used by patients. The doctor controls the power on and off of the first projection component 2 through an infrared proximity sensor 3. When the doctor is performing surgery, without touching any physical objects, the doctor can operate the device through the projected virtual image 4 in the air. There is no need to worry about the device being misoperated, nor about the hands being secondarily contaminated. Moreover, the infrared proximity sensor 3 is used to control the switch of the air projection screen interface. When operation is required, the user swipes a hand across the sensing area of the infrared proximity sensor 3, and the first projection component 2 (i.e., the air projection screen device) is powered on, and the setting button is projected into the air. The doctor can then operate the device in the air. When the device does not need to be operated, the doctor can swipe a hand across the sensing area of the infrared proximity sensor 3 again. At this time, the air projection device is turned off. The doctor does not need to worry about colliding with the touch device.

[0027] More specifically, refer to Figure 2 , the device consists of an infrared proximity sensor 3, a DC power supply 7, a high-brightness display screen 6, a projection glass 5, a gesture recognition sensor 8, and a control unit 10. When the user swipes a hand across the sensing area of the infrared proximity sensor 3, the infrared proximity sensor 3 sends a pulse signal to the control unit 10, and the control unit 10 sends an activation command to the high-brightness display screen 6 and the gesture recognition sensor 8. The image of the high-brightness display screen 6 is projected onto the air through the projection glass 5, forming a projected virtual image 4. In this embodiment, the gesture recognition sensor 8 emits an infrared light field 9 that covers the area of the projected virtual image 4. When the operator touches the projected virtual image 4 with a finger, the finger will enter the infrared light field 9, and the gesture recognition sensor 8 will send the coordinates (X, Y) of the finger in the light field to the control unit 10. The coordinates (X, Y) need to correspond to the instructions displayed on the projected virtual image 4. The control unit 10 will send the instructions corresponding to the coordinates (X, Y) to the actuator of the system. Thus, a human-machine interaction with the device is completed. When the operator temporarily does not need to operate the interaction interface, the operator can swipe a hand across the infrared proximity sensor 3 again, and the infrared proximity sensor 3 sends a pulse signal to the control unit 10 again. At this time, the control unit 10 will put the high-brightness display screen 6 and the gesture recognition sensor 8 into the standby state to prevent accidental triggering.

[0028] The specific embodiments of the present disclosure have at least the following features:

[0029] 1. The operator operates the device in the air without touching physical objects, meeting the hygiene requirements. For example, in a surgical scenario, there is no risk of secondary infection.

[0030] 2. Since the operator operates in the air, there is no risk of soiling the screen, and misoperation is also avoided (foreign objects on the screen, especially conductors such as water, will trigger misoperation).

[0031] 3. The projected virtual image, which can be located at a position far from the device, avoiding the risk of collision between the device and the operator.

[0032] 4. Compared with capacitive touchscreens, this solution has a longer service life.
