Description

Ring Controller and Wireless Communication System

[0001] The present disclosure relates to a ring-type controller and a wireless communication system.

[0002] Conventionally, controllers for operating electronic devices have been portable or worn on the body. In particular, controllers worn on the body must be small, which can limit the operations that can be performed.

[0003] The smart ring described in Patent Document 1 measures finger flexion or finger extension using a flexion sensor (see Patent Document 1).

[0005] However, with the conventional technology described above, for example, when a person operates an electronic device by pointing a finger in a space such as AR (Augmented Reality) glasses, the person has to bend and straighten their finger, which can make the operation complicated.

[0006] The present disclosure has been made in consideration of the above circumstances, and has as its object to provide a ring-type controller and a wireless communication system that can be easily operated by the user.

[0007] One aspect is a ring-type controller comprising a ring portion and a proximity sensor provided on the ring portion, the proximity sensor being positioned at a position where it can detect the distance between a specified first finger on which the ring portion is worn and another second finger.

[0008] One aspect is a wireless communication system including a ring controller and a host computer capable of communicating via a wireless module.

[0009] According to the present disclosure, it is possible to simplify the operation of a ring-type controller and a wireless communication system for the user.

[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0012] (First embodiment) [Ring-type controller] <Appearance of ring-type controller> Fig. 1 is a diagram showing the general configuration of a ring-type controller 1 according to an embodiment. For ease of explanation, Fig. 1 shows XYZ orthogonal coordinate axes, which are three-dimensional orthogonal coordinate axes. The ring-type controller 1 includes a ring unit 11, two proximity sensors 21, 22, and one positioning unit 31.

[0013] In this embodiment, the ring controller 1 has a single ring structure. The ring controller 1 may be called, for example, a ring device. The ring unit may be called, for example, simply a ring. The names of the other components in this embodiment are also examples for the purpose of explanation, and the components may be called by any other names.

[0014] The ring portion 11 has a ring-like shape. Here, the ring-like shape of the ring portion 11 is not particularly limited, and may be, for example, a circular shape or an elliptical shape. In this embodiment, the ring portion 11 has a circular shape when projected onto the XY plane. The ring portion 11 has a hole that penetrates parallel to the Z axis in the center of such a circular shape. In this embodiment, the ring portion 11 is, for example, a single-stage portion.

[0015] The two proximity sensors 21 are each disposed on the side surface of the outer periphery of the ring portion 11. The two proximity sensors 21 are disposed on the side surface with a predetermined distance between them. The predetermined distance may be expressed, for example, as a rotation angle around the central axis of the circular shape of the ring portion 11, or as a distance on the side surface of the outer periphery of the ring portion 11.

[0016] The positioning portion 31 is disposed on the side surface of the outer periphery of the ring portion 11. The positioning portion 31 is disposed on this side surface at a predetermined distance from the proximity sensor 21. In this case, the positioning portion 31 is also disposed on this side surface at a predetermined distance from the proximity sensor 22. Here, the shape of the positioning portion 31 is not particularly limited, and may have, for example, a protruding shape such as a cube or sphere, or any decorative shape. The decoration may be, for example, letters, numbers, symbols, or any pattern. Furthermore, the shape of the positioning portion 31 may be, for example, a shape that protrudes from the side surface of the outer periphery of the ring portion 11, or a shape that is engraved on the side surface of the outer periphery of the ring portion 11.

[0017] In this embodiment, the positioning unit 31 indicates to the user (human) the position on the finger (in this embodiment, the index finger of the left hand) on which the ring controller 1 is worn. In other words, in this embodiment, the user wears the ring controller 1 on a predetermined finger of a predetermined hand of the user so that the positioning unit 31 is located in a predetermined position when the ring controller 1 is worn on a predetermined finger of a predetermined hand of the user.

[0018] In this embodiment, the ring-type controller 1 is worn on the index finger of the user's left hand. Fig. 1 shows a direction D1 in which the index finger of the left hand is inserted into the ring portion 11.

[0019] In this embodiment, when the ring controller 1 is inserted onto the index finger of the user's left hand, the ring controller 1 is inserted onto the index finger so that the positioning unit 31 is positioned above the index finger. In this case, the proximity sensor 21 detects whether or not the ring controller 1 is in proximity to the middle finger of the user's left hand. Furthermore, the proximity sensor 22 detects whether or not the ring controller 1 is in proximity to the thumb of the user's left hand.

[0020] Here, the position determined by the positioning unit 31 is not particularly limited, and does not necessarily have to be above the finger on which the ring-type controller 1 is worn, but may be, for example, below or to the side of the finger on which the ring-type controller 1 is worn.

[0021] 2 is a diagram showing an example of the configuration of a wireless communication system Q1 according to an embodiment and an example of the configuration of functional blocks of the control circuit 211 of the ring controller 1. The wireless communication system Q1 includes the ring controller 1, a host computer 212, and a charger 213. In this embodiment, the host computer 212 and the charger 213 are devices external to the ring controller 1. The control circuit 211 is provided in the ring controller 1. Note that, for example, the charger 213 may be considered not to be included in the wireless communication system Q1.

[0022] In this embodiment, the ring controller 1 transmits, for example, various instructions and various information to the host computer 212 by wirelessly communicating with the host computer 212. The host computer 212 acquires various instructions or information based on the information received from the ring controller 1. The charger 213 supplies power to the ring controller 1.

[0023] Here, the host computer 212 may be any device, such as a personal computer (PC), a smartphone, AR glasses, or VR (Virtual Reality) glasses. Also, various types of chargers may be used as the charger 213.

[0024] The control circuit 211 includes a proximity sensor unit 231, an IMU (Inertial Measurement Unit) sensor 232, a wireless module 233, a battery 234, a charging connector 235, a battery control IC (Integrated Circuit) 236, and a microcontroller (also referred to as a microcomputer in this embodiment for convenience of explanation) 237. In this embodiment, the proximity sensor unit 231 includes a proximity sensor 21 and a proximity sensor 22.

[0025] Each of the proximity sensors 21 and 22 of the proximity sensor unit 231 functions as a distance measurement sensor. The proximity sensor 21 detects information regarding the degree of proximity to a predetermined finger (in this embodiment, the middle finger of the left hand). The degree may be, for example, information indicating the distance from the finger. The proximity sensor 22 detects information regarding the degree of proximity to a predetermined finger (in this embodiment, the thumb of the left hand). The degree may be, for example, information indicating the distance from the finger.

[0026] The proximity sensor unit 231 transmits information (detection information) relating to the detection results of the proximity sensors 21 and 22 to the microcomputer 237. The proximity sensor unit 231 is controlled by the microcomputer 237.

[0027] Note that detection may be called, for example, measurement or measurement. Furthermore, detection information may be called, for example, measurement information or measurement information, and may also be called, for example, detected values, measured values, or measured values. Furthermore, various types of information may be called, for example, data.

[0028] The IMU sensor 232 includes, for example, an acceleration sensor and a gyro sensor. The IMU sensor 232 detects information according to the movement of the hand wearing the ring controller 1. The IMU sensor 232 transmits information related to the detection results (detection information) to the microcomputer 237. The IMU sensor 232 is controlled by the microcomputer 237. Note that the IMU sensor 232 may include, for example, either an acceleration sensor or a gyro sensor.

[0029] The wireless module 233 performs wireless communication with the host computer 212. There are no particular limitations on the wireless communication method, and methods such as Bluetooth (registered trademark) may be used, for example. Transmission and reception of the wireless module 233 are controlled by a microcomputer 237.

[0030] The battery 234 is, for example, a secondary battery that charges and supplies power. Here, the battery 234 may be configured to be detachable from the main body of the ring controller 1 (in the example of FIG. 2 , the parts of the ring controller 1 other than the battery 234), or may be integrated and not detachable. Note that a replaceable primary battery may be used as the battery 234, in which case the charger 213 and charging connector 235 may not be provided. In this case, for example, the battery 234 may be considered to be an external component of the ring controller 1.

[0031] The charging connector 235 receives power from the charger 213 and supplies that power to the battery control IC 236. Note that the charging connector 235 and the charger 213 may be configured to supply power contactlessly, or may be configured to supply power via a wire. When the charging connector 235 and the charger 213 supply power via a wire, for example, power may be supplied when the ring controller 1 is not being worn by the user.

[0032] The battery control IC 236 controls charging of the battery 234 and power supply from the battery 234. In this embodiment, the battery control IC 236 supplies power to each of the proximity sensor unit 231, the IMU sensor 232, the wireless module 233, and the microcomputer 237 using power charged in the battery 234. The battery control IC 236 also charges the battery 234 using power supplied from the charging connector 235.

[0033] The microcomputer 237 performs various processes and controls. The microcomputer 237 communicates information with the host computer 212 via the wireless module 233. The microcomputer 237 receives information about the detection results (detection information) from the proximity sensor unit 231. The microcomputer 237 receives information about the detection results (detection information) from the IMU sensor 232. The microcomputer 237 transmits instructions to the host computer 212 according to the user's operation, for example, based on one or both of the information from the proximity sensor unit 231 and the information from the IMU sensor 232.

[0034] Here, the microcomputer 237 may, for example, identify an instruction corresponding to the user's operation content based on both the information from the proximity sensor unit 231 and the information from the IMU sensor 232, or may identify an instruction corresponding to the user's operation content based on any one of the information from the proximity sensor unit 231 and the information from the IMU sensor 232. As another example, the microcomputer 237 may transmit one or both of the information from the proximity sensor unit 231 and the information from the IMU sensor 232 to the host computer 212 without identifying an instruction corresponding to the user's operation content. In this case, the host computer 212 identifies an instruction corresponding to the user's operation content based on the information received from the microcomputer 237.

[0035] Note that when a series of processes are performed by the microcomputer 237 and the host computer 212, the division of the processes performed by the microcomputer 237 and the processes performed by the host computer 212 may be arbitrary. As one example, the microcomputer 237 may transmit to the host computer 212 information about the detection results themselves (e.g., distance) by the proximity sensors 21, 22, or information about the presence or absence of proximity obtained from the detection results. As another example, the microcomputer 237 may transmit to the host computer 212 information about the detection results themselves (e.g., one or both of acceleration and angular velocity) by the IMU sensor 232, or information about movement obtained from the detection results (e.g., information such as the distance moved by the ring controller 1).

[0036] As another example, the microcomputer 237 may generate predetermined information based on the detection results of the proximity sensor unit 231 and the detection results of the IMU sensor 232, and transmit the information to the host computer 212. For example, the predetermined information may be information for display, and in this case, the host computer 212 displays the information received from the microcomputer 237 via the wireless module 233 on a screen.

[0037] The microcomputer 237 or the host computer 212 may determine whether the proximity sensor 21 is in proximity to a predetermined finger (in this embodiment, the middle finger of the left hand) based on, for example, detection information from the proximity sensor 21. In this case, for example, the detection information may be information on the distance (separation distance) from the finger, and it may be determined that the proximity is present when the distance from the finger is equal to or less than a predetermined threshold (or less than the predetermined threshold), and it may be determined that the proximity is not present in other cases. Similarly, the microcomputer 237 or the host computer 212 may determine whether the proximity sensor 22 is in proximity to a predetermined finger (in this embodiment, the thumb of the left hand) based on, for example, detection information from the proximity sensor 22. In this case, for example, the detection information may be information on the distance (separation distance) from the finger, and it may be determined that the proximity is present when the distance from the finger is equal to or less than a predetermined threshold (or less than the predetermined threshold), and it may be determined that the proximity is not present in other cases. Note that the thresholds for the proximity sensors 21 and 22 may be the same or different, for example.

[0038] In this embodiment, the proximity sensor 21 and the proximity sensor 22 are arranged at different, separated locations (positions) on the ring unit 11. Furthermore, the components of the ring-type controller 1 shown in FIG. 2 other than the proximity sensors 21 and 22 may be arranged together in one location on the ring unit 11, for example, or may be arranged separately at multiple, separated locations on the ring unit 11. When these components are arranged together in one location on the ring unit 11, this location may be, for example, the same location as any one of the two proximity sensors 21 and 22, or may be a different location from the two proximity sensors 21 and 22.

[0039] <Control of Control Circuit from Host Computer> A configuration may be used in which a predetermined instruction (control data) is transmitted from the host computer 212 to the microcomputer 237 of the control circuit 211. The instruction may be a sleep instruction. For example, the host computer 212 may issue a sleep instruction to the microcomputer 237 via the wireless module 233 at a desired timing. In this case, the microcomputer 237 puts all or part of the control circuit 211 into a sleep state in response to receiving the instruction. Note that in the sleep state, for example, power consumption is reduced. In this case, the sleep state may be referred to as a power-saving state or the like.

[0040] [User Operation Contents] Figure 3 is a diagram schematically showing a method for wearing the ring controller 1 according to this embodiment. For ease of explanation, Figure 3 shows the same XYZ orthogonal coordinate axes as Figure 1. Figure 3 shows the ring controller 1 from the perspective of looking at the hole in the ring portion 11 of the ring controller 1.

[0041] In this embodiment, the ring controller 1 is worn on the index finger of the user's left hand by inserting the index finger in a direction from the front to the back of the page in FIG. 3 . In this case, the proximity sensor 21 is disposed in a position where it can detect whether the middle finger of the user's left hand is close to the index finger. Furthermore, the proximity sensor 22 is disposed in a position where it can detect whether the thumb of the user's left hand is close to the index finger. Therefore, the microcomputer 237 or the host computer 212 can identify an instruction corresponding to the user's operation based on the detection results of the two proximity sensors 21, 22.

[0042] In this embodiment, in the example of FIG. 3 , when viewed from the negative side to the positive side of the Z axis, the proximity sensor 21 is disposed 90 degrees (or approximately 90 degrees) to the left (left side in FIG. 3 ) of the positioning unit 31 in the ring portion 11. That is, in this embodiment, the position of the positioning unit 31 and the position of the proximity sensor 21 are offset by 90 degrees (or approximately 90 degrees) in terms of the angle of rotation around the central axis of the circular shape of the ring portion 11. Also, in this embodiment, in the example of FIG. 3 , when viewed from the negative side to the positive side of the Z axis, the proximity sensor 22 is disposed at a position approximately 90 to 180 degrees (for example, 157.5 degrees or 135 degrees) to the right (right side in FIG. 3 ) of the positioning unit 31 in the ring portion 11. That is, in this embodiment, the position of the positioning unit 31 and the position of the proximity sensor 22 are offset by 90 to 180 degrees in terms of the angle of rotation around the central axis of the circular shape of the ring portion 11. Thus, in this embodiment, the positions of proximity sensors 21 and 22 are offset by an angle ranging from 90 degrees to 180 degrees (for example, 112.5 degrees or 135 degrees) in terms of the rotation angle when centered on the central axis of the circular shape of ring portion 11. Note that the arrangement of each component (for example, the position of the rotation angle) shown in this embodiment is an example for explanatory purposes and is not necessarily an exact value, and any practically effective arrangement of each component may be used.

[0043] <Examples of User Operation Contents> Examples of user operation contents are shown with reference to Figures 4A to 4D. In the examples of Figures 4A to 4D, the ring controller 1 is worn on the index finger F2 of the user's left hand H1.

[0044] 4A and 4B are diagrams showing an example of the posture of a left hand H1 wearing a ring-type controller 1 according to an embodiment. FIGS. 4A and 4B are diagrams showing the same posture of the left hand H1 as viewed from different perspectives. In the example of FIG. 4A , the user is assuming a pointing posture with only the index finger F2 of the left hand H1 extended. In this case, based on the detection result of the proximity sensor 21, it is determined that the middle finger F3 of the user's left hand H1 is not in proximity to the index finger F2, and based on the detection result of the proximity sensor 22, it is determined that the thumb F1 of the user's left hand H1 is not in proximity to the index finger F2.

[0045] 4C is a diagram showing an example of the posture of a left hand H1 wearing a ring-type controller 1 according to an embodiment. In the example of Fig. 4C, the user is assuming a posture in which the index finger F2 and middle finger F3 of the left hand H1 are extended to point with two fingers. In this case, based on the detection result of the proximity sensor 21, it is determined that the middle finger F3 of the user's left hand H1 is in proximity to the index finger F2, and based on the detection result of the proximity sensor 22, it is determined that the thumb F1 of the user's left hand H1 is not in proximity to the index finger F2.

[0046] 4D is a diagram showing an example of the posture of a left hand H1 wearing a ring-type controller 1 according to an embodiment. In the example of Fig. 4D , the user is assuming a posture for performing a grasp operation, with the index finger F2 and middle finger F3 of the left hand H1 touching and the index finger F2 and thumb F1 extended so as to touch. In this case, based on the detection result of the proximity sensor 21, it is determined that the middle finger F3 of the user's left hand H1 is in proximity to the index finger F2, and based on the detection result of the proximity sensor 22, it is determined that the thumb F1 of the user's left hand H1 is in proximity to the index finger F2.

[0047] 4A to 4D are merely examples, and any posture of the left hand H1 may be used to determine the user's operation. For example, the examples of FIGS. 4A to 4D show cases in which the user's operation is identified based on the detection results of the proximity sensors 21 and 22 corresponding to the posture of the user's left hand H1. However, as another example, the user's operation may be identified based on both the detection results of the proximity sensors 21 and 22 and the detection result of the IMU sensor 232.

[0048] <Example of Use of Ring Controller> Fig. 5 is a diagram showing an example of use of the ring controller 1 according to the embodiment. Fig. 5 shows a screen 331 being projected onto a wall 311 using the projector function. The image on the screen 331 includes an image of an operation target 351. In the example of Fig. 5, the screen 331 is a projected screen that is processed by the host computer 212. Also, in the example of Fig. 5, the operation target 351 is a cursor that can be moved on the screen 331.

[0049] 5 also shows the ring controller 1 and the user's left hand H1 wearing the ring controller 1. The ring controller 1 is worn on the index finger F2 of the left hand H1.

[0050] In the example of FIG. 5 , when the user positions his or her left hand H1 in a specific position, an instruction corresponding to that position can be notified to the host computer 212 via the ring controller 1. In the example of FIG. 5 , that position is a position in which the tip of the index finger F2 is pointed in a specific direction D11. The host computer 212 executes various processes based on the content of the instruction (user operation content) received from the ring controller 1. The process is not particularly limited and may be, for example, processing related to an object pointed at by the cursor or cursor movement processing. The host computer 212 identifies a process corresponding to the user operation content based on the relationship (e.g., relative position) between the screen generated by the host computer 212 (in this example, the screen 331 displayed on the wall 311) and the user operation content, and executes the process.

[0051] Note that while this embodiment illustrates a case in which the content of a user's operation is notified from the ring controller 1 to the host computer 212, as another example, the content of the user's operation may be identified by the microcomputer 237 of the ring controller 1, and the microcomputer 237 may execute processing according to the content of the operation. Furthermore, this embodiment illustrates a case in which a predetermined screen (screen 331 in the example of FIG. 5) is projected onto the wall 311, as another example, a configuration in which such a screen is projected onto one or both sides of glasses worn by the user may be used.

[0052] As described above, the ring controller 1 according to this embodiment simplifies operation for the user (human). For example, the user can perform intuitive operations by pointing at the space projected on the wall 311 or AR glasses, etc. For example, the user can operate or control an electronic device (the host computer 212 in this embodiment) by wearing the ring controller 1 on the fingers of the hand and positioning the hand in a specific position.

[0053] The user can easily operate the user interface by, for example, bringing the finger wearing the ring controller 1 close to another finger. The user can also easily operate the user interface by, for example, bringing the finger wearing the ring controller 1 close to two or more other fingers. By referring to the positioning unit 31, the user can easily visually recognize how the ring controller 1 should be worn.

[0054] The ring controller 1 according to this embodiment can transmit information about the detection results of the proximity sensors 21, 22 to the host computer 212, which allows the host computer 212 to accurately grasp, for example, the position of a specific finger (for example, whether or not that finger is in proximity) relative to the finger of the user wearing the ring controller 1. For example, in a configuration in which the detection results of each sensor (in this embodiment, the proximity sensors 21, 22 and the IMU sensor 232) are transmitted from the ring controller 1 to the host computer 212, accurate information about the position of the ring controller 1 and the like can be presented to the host computer 212.

[0055] 4A to 4D and 5, the ring controller 1 is worn on the fingers of the user's left hand, but the same applies to examples in which a ring controller is worn on the fingers of the user's right hand. For example, the ring controller worn on the fingers of the user's right hand may have a configuration that is symmetrical to the ring controller 1 worn on the fingers of the user's left hand, or it may have a different configuration.

[0056] In this embodiment, the ring controller 1 worn on the index finger is illustrated, but as another example, a ring controller worn on a finger other than the index finger may be implemented. As a specific example, a configuration may be used in which the ring controller 1 is worn on the middle finger of a specific hand of the user, and a proximity sensor detects the degree of proximity between the middle finger and other fingers. In this case, the other fingers may be, for example, one or more of the index finger, ring finger, and thumb.

[0057] The locations where the two proximity sensors 21, 22 and the positioning unit 31 are provided on the ring unit 11 of the ring controller 1 are shown in the present embodiment as an example, and the locations where they are provided may be designed arbitrarily. These locations may be designed arbitrarily for each type, for example, for the left hand only, the right hand only, or for both the left and right hands. For example, while the present embodiment illustrates a case where the ring controller 1 is worn on the user's left hand, the ring controller 1 according to the present embodiment may be worn on the right hand as is, or a ring controller in which one or more of the proximity sensors 21, 22 and the positioning unit 31 are replaced with other locations may be worn on the right hand.

[0058] In this embodiment, the ring-type controller 1 is shown having two proximity sensors 21 and 22 on the ring unit 11, but as another configuration example, a ring-type controller having three or more proximity sensors on the ring unit may be implemented. In other words, the ring-type controller may have at least two proximity sensors on different locations on the ring unit.

[0059] Second Embodiment [Ring-Type Controller] Fig. 6 is a diagram showing a schematic configuration of a ring-type controller 501 according to a second embodiment. For ease of explanation, Fig. 6 shows XYZ orthogonal coordinate axes, which are three-dimensional orthogonal coordinate axes. The ring-type controller 501 includes a ring unit 511 and a proximity sensor 521.

[0060] The proximity sensor 521 is disposed at a predetermined location on the outer circumferential side of the ring unit 511. The proximity sensor 521 has the same function as, for example, the proximity sensor 21 shown in FIG. 1. The ring-type controller 1 includes, for example, a control circuit having a configuration similar to that of the control circuit 211 shown in FIG. 2, in which the proximity sensor unit 231 includes one proximity sensor 521. The control circuit or the host computer (a device equivalent to the host computer 212 shown in FIG. 2) identifies the user's operation based on the detection results of the proximity sensor 521, or based on the detection results of the proximity sensor 521 and the detection results of the IMU sensor (a sensor equivalent to the IMU sensor 232 shown in FIG. 2).

[0061] Here, the ring controller 501 according to this embodiment differs from the ring controller 1 according to the first embodiment in that it has one proximity sensor 521 (i.e., it does not have two proximity sensors) and does not have a positioning unit. In this embodiment, the ring unit 511 does not have a positioning unit, and the user wears the ring controller 501 on a specific finger by referring to, for example, the position of the proximity sensor 521 provided on the ring unit 511.

[0062] As described above, the ring controller 501 according to this embodiment makes operation easy for the user (human). For example, the user can perform simple operations by bringing the finger wearing the ring controller 501 close to another finger.

[0063] Third Embodiment [Ring-Type Controller] Fig. 7 is a diagram showing the schematic configuration of a ring-type controller 601 according to a third embodiment. For ease of explanation, Fig. 7 shows XYZ orthogonal coordinate axes, which are three-dimensional orthogonal coordinate axes. The ring-type controller 601 includes a ring unit 611 and two proximity sensors 621 and 622.

[0064] The proximity sensors 621 and 622 are each disposed at a predetermined location on the outer circumferential side of the ring portion 611. As an example, these two proximity sensors 621 and 622 may be disposed in the same locations as the two proximity sensors 21 and 22 according to the first embodiment.

[0075] Therefore, with the ring controller, a user can easily perform operations with a simple action, such as bringing a first finger and a second finger closer together. The user's finger actions can include, for example, bringing the finger wearing the ring controller closer to another finger (e.g., the thumb) or pointing at a specific object with two fingers, thereby enabling various commands to be given. Here, the first finger and the second finger may each be any finger. Furthermore, the ring controller may be applicable to either or both of the right hand and the left hand. In this embodiment, the ring controllers 1, 501, and 601 are examples of ring controllers, the ring units 11, 511, and 611 are examples of ring units, the proximity sensors 21, 22, 521, 621, and 622 are examples of proximity sensors, the index finger F2 of the left hand H1 is an example of the first finger, and the thumb F1 or middle finger F3 is an example of the second finger.
