For example, on-demand multimedia content (Multimedia on Demand, MOD) or on-demand video system (Video on Demand, VOD) and so on.

However, most of the current smart TVs only provide the user with a remote control to operate. Most of the existing remote controllers only have input buttons such as up, down, left and right direction keys and number keys. With the diversification of usage scenarios, it is very inconvenient for users to select, control and input through the existing remote control. In particular, operations such as zooming in, zooming out, clicking or dragging are often required for menu operations and web browsing after being connected to the Internet. Existing remote controllers cannot simply issue the above instructions.

In an existing way of controlling a smart TV by voice control or gesture operation, a hardware device for sound retrieval or image retrieval must be added to the smart TV. The correct recognition rate of the voice control method needs to be improved, and the use of image retrieval equipment to recognize gesture operations is limited by the effective shooting range of the image retrieval equipment. Furthermore, when multiple people watch the smart TV at the same time, existing voice control or gesture operations are likely to interfere with each other and cause recognition errors. Accordingly, it is necessary to propose a more convenient method for performing input control operations on smart TVs to meet diversified use scenarios.

FIG. 2 is a schematic diagram of an application scenario of a ring-type remote control device according to an embodiment of the present invention. Please refer to FIG. 1 and FIG. 2 together. The ring-type remote control device 100 of this embodiment is suitable for being arranged around a finger of a user. In this embodiment, the ring-type remote control device 100 is, for example, disposed around the index finger f1 of the user, but the invention is not limited thereto.

The ring-type remote control device 100 includes a processing unit 110 , a wireless communication module 120 , a motion sensor module (Motion sensor module) 130 and a first proximity sensor (Proximity sensor) 140 . Its functions are described as follows:

The processing unit 110 is, for example, a central processing unit (Central Processing Unit, CPU), or other programmable general purpose or special purpose microprocessor (Microprocessor), digital signal processor (Digital Signal Processor, DSP), microcontroller (Micro-controller unit, MCU). The processing unit 110 is configured to receive the sensing signals from the motion sensing module 130 and the first proximity sensor 140 , and transmit the command to be transmitted to the wireless communication module 120 .

The wireless communication module 120 can be, for example, one of a radio frequency (Radio frequency, RF) module, a Bluetooth module, and a wireless fidelity (Wireless Fidelity, Wi-Fi) module, but is not limited to the above. The wireless communication module 120 can wirelessly transmit the instructions sent by the processing unit 110 to an interactive receiving device (not shown). The interactive receiving device is, for example, a smart TV or other electronic devices with display and wireless receiving capabilities, which is not limited herein.

The motion sensing module 130 includes an acceleration sensor (Accelerometer) 132 and a gyro sensor (Gyro sensor) 134 . The acceleration sensor 132 is used to sense the movement acceleration or impact force of the ring-type remote control device 100 . The gyro sensor 134 is used to sense the rotational angular velocity of the ring-type remote control device 100 . The motion sensing module 130 can generate different control signals according to different accelerations and angular velocities, and generate position information of the ring-type remote control device 100 according to them. It should be noted that the motion sensing module 130 can also recognize the double click function of the ring-type remote control device 100 to generate a corresponding control signal.

The first proximity sensor 140 is a device capable of sensing the approach of an object. The forms of the proximity sensor include inductive, capacitive, photoelectric, microwave, etc., which are not limited here. The proximity sensor is sensitive to the approaching target, so it can recognize the approach of the target and output a corresponding signal. In this embodiment, the ring-type remote control device 100 is, for example, set around the user's index finger f1. Therefore, the first proximity sensor 140, for example, can be set to sense whether the user's thumb or middle finger is approaching. The function of the index finger f1.

Fig. 3 is a flow chart of a control method for zooming in and out according to an embodiment of the present invention. The method of this embodiment is applicable to the ring-type remote control device 100 shown in FIG. 1 . In this embodiment, it is assumed that the ring-type remote control device 100 is disposed around the user's index finger f1 (as shown in FIG. 2 ). The detailed steps of the method of this embodiment are described below in conjunction with each component in the ring-type remote control device 100:

First, in step S310 , the motion sensing module 130 detects the location information of the ring-type remote control device 100 , and the processing unit 110 can judge the positioning level and movement status of the ring-type remote control device 100 according to the location information. Moreover, the first proximity sensor 140 detects distance information between the user's second finger and the first finger. In this embodiment, the first finger refers to the user's index finger f1; the second finger refers to the user's thumb or middle finger.

In step S320 , the processing unit 110 simultaneously refers to the position information and the distance information to determine the distance change between the first finger and the second finger.

Since the first proximity sensor 140 can only sense objects within a certain distance, the sensing range varies according to the sensing capability of the first proximity sensor 140 . Therefore, in step S330 , if the first proximity sensor 140 senses that the distance between the first finger and the second finger is shortened, it can correspondingly generate a zoom-out signal to the processing unit 110 . On the contrary, if the first proximity sensor 140 senses that the distance between the first finger and the second finger increases, it can correspondingly generate an amplified signal to the processing unit 110 .

In step S340, the processing unit 110 determines which command to generate to the wireless communication device 120 according to the received signal. In detail, if the processing unit 110 receives the reduction signal, it will issue a corresponding reduction command to the wireless communication device 120, so that the wireless communication device 120 sends the data of the reduction command to the interactive receiving device to manipulate the display screen of the interactive receiving device. The corresponding target is reduced. Similarly, if the processing unit 110 receives the amplifying signal, it will issue a corresponding amplifying command to the wireless communication device 120, so that the wireless communication device 120 sends the data of the amplifying command to the interactive receiving device to control the display screen of the interactive receiving device. The operation of zooming in on the corresponding target.

Accordingly, by wearing the ring-type remote control device 100 , the user can easily manipulate the object to zoom in or out by changing the distance between the index finger and the thumb (or the index finger and the middle finger), which is quite intuitive and convenient for the user.

Fig. 4 is a flowchart of another zoom-in and zoom-out control method according to an embodiment of the present invention. Please refer to Figure 1 and Figure 4 below.

First, the motion sensing module 130 detects the position information of the ring-type remote control device 100; the first proximity sensor 140 detects the distance information between the user's second finger and the first finger (step S410). Next, the processing unit 110 judges that the ring-type remote control device 100 is in a horizontal state, a vertical state or an inclined state, and judges the distance change between the first finger and the second finger according to the distance information (step S420 ).

If the ring-type remote control device 100 is in a horizontal state, then continue to step S430 to select to generate a horizontal zoom-out signal or a horizontal zoom-in signal according to the distance change between the first finger and the second finger. If the ring-type remote control device 100 is in the vertical state, continue to step S440 , and select to generate a vertical zoom-out signal or a vertical zoom-in signal according to the distance change between the first finger and the second finger. If the ring-type remote control device 100 is in a tilted state, then proceed to step S450 to select and generate a bevel reduction signal or a bevel enlargement signal according to the distance change between the first finger and the second finger. Then, the ring-type remote control device 100 can transmit a corresponding zoom-out command or zoom-in command to the interactive receiving device according to the received zoom-out signal or zoom-in signal (step S460 ).

It should be noted that in this embodiment, a preset angle can also be preset. When the motion sensing module 130 judges that the inclination angle of the ring-type remote control device 100 is greater than the preset angle, the processing unit 110 issues a diagonal line from the upper right to the lower left. Zoom in or out commands on the . If the inclination angle of the ring-type remote control device 100 is less than or equal to the preset angle, the processing unit 110 issues a zoom-in or zoom-out command from the upper left to the lower right diagonal. Wherein, the preset angle can also be preset by the user according to actual application conditions.

In other embodiments, the ring-type remote control device 100 shown in FIG. 1 can also be configured with other conditions to generate different control signals. For example, when the first proximity sensor 140 detects that the distance between the first finger and the second finger is fixed at a certain value and exceeds a preset time, the processing unit 110 also generates a first control signal to the wireless communication module 120 . Please refer to the instructions below.

FIG. 5 is a schematic diagram of an application scenario of a ring-type remote control device according to an embodiment of the present invention. Please refer to FIG. 5 , assuming that the user's thumb f2 touches one side of the ring-type remote control device 100 for a period of time (for example, 2 seconds), the first proximity sensor 140 detects that there is a gap between the index finger f1 and the thumb f2. The distance has not changed and exceeds a preset time, so the processing unit 110 may, for example, generate a first control signal to the wireless communication module 120, the first control signal is, for example, a click signal. The wireless communication module 120 will transmit the click command corresponding to the click signal to the interactive receiving device, so as to control the interactive receiving device to select the corresponding target.

Furthermore, if the distance between the index finger f1 and the thumb f2 does not change and remains for a period of time, but the motion sensing module 130 detects that the ring-type remote control device 100 is continuously moving, the processing unit 110 may generate a second control signal, for example To the wireless communication module, the second control signal is, for example, a drag signal. The wireless communication module 120 transmits the drag command corresponding to the drag signal to the interaction receiving device, so as to control the interaction receiving device to move the selected object along the moving direction of the ring-type remote control device 100 .

Another embodiment is given below as an example that the present invention can indeed be implemented according to this. FIG. 6 is a block diagram of a ring-type remote control device according to another embodiment of the present invention. Please refer to FIG. 6 . The difference between the ring-type remote control device 600 shown in FIG. 6 and FIG. Wherein, the second proximity sensor 650 has the same or similar structure as the first proximity sensor 140 , which will not be repeated here. The display unit 660 is, for example, an electronic paper display, etc., and can be used to help remind the user whether the gesture operation is correct. The input device 670 is, for example, one or more physical buttons, which allow the user to generate a trigger signal by pressing the physical buttons.

In detail, when both the first proximity sensor 140 and the second proximity sensor 650 are turned on, it means that the ring-type remote control device 600 is in the first state. In the first state, the first proximity sensor 140, for example, can be used to sense the change in the distance between the user's index finger and thumb, and the second proximity sensor 650, for example, can be used to sense the change in the distance between the user's index finger and middle finger. . Combined with the position information sensed by the motion detection module 130 , the processing unit 110 can generate different control signals for zooming in, zooming out, dragging, clicking, etc. according to the matching.

When the first proximity sensor 140 is turned on and the second proximity sensor 650 is turned off, it means that the ring-type remote control device 600 is in the second state. When the first proximity sensor 140 is turned off and the second proximity sensor 650 is turned on, it means that the ring-type remote control device 600 is in the third state. Different state control signals can be generated corresponding to different states, and the operation instructions corresponding to the state control signals can be set by the user.

FIG. 7 is a flow chart of a point-and-click control method according to another embodiment of the present invention. The method of this embodiment is applicable to the ring-type remote control device 600 shown in FIG.

The motion detection module 130 detects the position information of the ring-type remote control device 600 , and the gyro sensor 134 detects the rotation angle of the ring-type remote control device for fixed-point rotation (step S710 ). Next, the processing unit 110 judges whether the rotation angle is greater than a preset rotation angle, and if so, the processing unit 110 generates a click signal to the wireless communication module 120 (step S720 ). The wireless communication module 120 of the ring-type remote control device 600 transmits the click instruction corresponding to the click signal to the interactive receiving device, so as to control the interactive receiving device to select the target (step S730 ). After confirming the selected target, the user can also zoom in or zoom out the selected target through the operation of changing the finger distance.

It should be noted that, in step S720 , the processing unit 110 can also determine whether the ring-type remote control device 600 is rotating clockwise or counterclockwise according to the rotation angle detected by the motion detection module 130 . When the ring-type remote control device 600 rotates clockwise, the processing unit 110 can correspondingly generate a first control signal; when the ring-type remote control device 600 rotates counterclockwise, the processing unit 110 can correspondingly generate a second control signal. In this embodiment, the commands corresponding to the first control signal and the second control signal can be set by the user. For example, the first control signal is, for example, a control instruction representing “Yes”; the second control signal is, for example, a control instruction representing “No” (“No”).
