Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the body-mounted electronic device according to the present invention is applied to a wristwatch.
FIG. 1 is an external view of a wristwatch according to the present embodiment, and FIG.

  As shown in FIG. 1, the wristwatch 1 includes a timepiece main body 10 and a wristband 11 locked to both ends of the timepiece main body. The watch body 10 includes a liquid crystal display screen 107 that displays various types of information such as date, time, and direction, and switches (operation units) 106a to 106f that allow the user to input destination information and the like. For example, the wristwatch 1 is detachably attached to a user's wrist or arm, and the watch body 10 comes into contact with the user's arm U when attached.

  As shown in FIG. 2, a housing portion is formed inside the watch body 10 by a back cover 113 and a side wall member 117, and an equipment module 114 is disposed in this housing portion. Although not shown in FIG. 2, the device module 114 includes a clock unit 120 that measures the current time, a display drive unit that performs display control of the liquid crystal display screen 107, and the like.

  The liquid crystal display screen 107 is disposed above the device module 114 and is fixed by an attachment member 115. The liquid crystal display screen 107 is covered with a windshield 112 supported by a side wall member 117, and a bezel 116 is provided around the windshield 112.

  In addition, the device module 114 includes traction force generation means for generating a traction force that pulls the user toward the direction in which the user should move when the user wearing the wristwatch 1 moves toward the destination. Prepare. In the present embodiment, the traction force generating means includes a first rotating disk 109A, a second rotating disk 109B, a weight 109C as a moving member, a driving unit 108 including a motor and a transmission mechanism, and a control for controlling the driving unit 108. Unit 111.

  The first rotating disk 109A and the second rotating disk 109B are disposed so as to overlap each other (here, the first rotating disk 109A is above), and are supported to be rotatable about the shaft 118. The weight 109C is between a slit S (see FIG. 3) provided in the radial direction from the approximate center of the first rotating disk 109A and a groove D (see FIG. 4) provided in an annular shape on the second rotating disk 109B. Retained.

  The groove portion D of the second rotating disk 109B is formed so as to always cross the slit S in a state where the first rotating disk 109A and the second rotating disk 109B are overlapped. Therefore, the weight 109C is held at a position where the slit S and the groove D intersect, and the position of the groove D where the slit S intersects when the first rotating disk and the second rotating disk are relatively rotated. It moves along the slit S according to (distance from the center).

  In the present embodiment, the groove D provided in the second turntable 109B is a first guide groove for moving the weight 109C at a high speed along the slit S when the second turntable 109B is rotated at a constant speed. D1 and second guide grooves D2 that are moved at a low speed are alternately arranged. In FIG. 4, between ab and cd becomes the 1st guide groove D1, and between bc and da becomes the 2nd guide groove.

  Specifically, the first guide groove D1 has a large radial displacement with respect to the rotation angle, and the second guide groove D2 has a small radial displacement with respect to the rotation angle. In FIG. 4, for example, in the first guide groove D1, the radial displacement (movement distance along the slit S) with respect to the rotation angle of 40 ° is substantially the slit length, and in the second guide groove D2, the rotation angle is 140 °. The radial displacement is approximately the slit length. In particular, the second guide groove D2 has a polygonal line shape, and the displacement in the radial direction with respect to the rotation angle of 40 ° between b and b1 is about 1/2 of the slit length, and between b1 and b2 and between b2 and b3 with respect to the rotation angle of 40 °. The radial displacement is about ¼ of the slit length, and b3-c is formed such that the radial displacement with respect to a rotation angle of 20 ° is zero.

  Accordingly, the speed when the weight 109C moves at the intersection between the first guide groove D1 and the slit S is larger than the speed when the weight 109C moves at the intersection between the second guide groove D2 and the slit S. That is, when the second turntable 109B is rotated clockwise at a constant speed while the first turntable 109A is fixed, the weight 109C moves along the slit S from the peripheral side to the center side at a high speed, and from the center side. It moves at a low speed toward the peripheral side.

  Here, when the weight 109 </ b> C moves along the slit S toward the center at a high speed, the user wearing the wristwatch 1 feels the fluctuation of the center of gravity of the watch body 10 remarkably. As a result, the user feels that the arm is pulled in the direction opposite to the moving direction of the weight 109C. On the other hand, when the weight 109C moves along the slit S toward the peripheral edge at a low speed, the change in the center of gravity of the watch body 10 becomes smaller than when the weight 109C moves at a high speed, and thus the user can pull the arm. I do not receive a sense.

  Accordingly, when the second rotating disk 109b is continuously rotated at a constant speed while the first rotating disk 109a is fixed, the user moves the weight 109C in a direction opposite to the moving direction of the weight 109C when moving at a high speed. You will receive only the feeling of being pulled. In the present embodiment, such a phenomenon is used to guide the direction to be moved to the user.

  FIG. 5 is a block diagram functionally showing each component incorporated in the watch body 10. As shown in FIG. 3, the watch body 10 includes a tilt sensor 101, an orientation sensor 102, a GPS system 103, a GPS antenna 104, a storage unit 105, an operation unit 106, a display unit 107, a drive unit 108, a communication unit 110, a clock unit. 120 and a control unit 111.

  The tilt sensor 101 constitutes a posture detection means for detecting the spatial posture of the watch body 10. Specifically, it is detected whether or not the surface of the watch body 10 is horizontal with respect to the ground. When the posture of the watch main body 10 detected by the tilt sensor 101 becomes a predetermined posture (for example, horizontal with respect to the ground) (the tilt sensor is “on”), the first and second turntables 109A, 109B is driven to guide the moving direction.

  The azimuth sensor 102 is, for example, a geomagnetic sensor, and constitutes azimuth detection means for acquiring the azimuth that the watch body 10 is facing. For example, when the timepiece main body is horizontal, the absolute azimuth at the current position, which is the first point, can correspond to the 3 o'clock direction, 6 o'clock direction, 9 o'clock direction, and 12 o'clock direction of the board surface.

  The GPS system 103 receives radio signals radiated from a plurality of GPS satellites (including GPS satellite orbits and time data from atomic clocks mounted on the satellites) via the GPS antenna 104, and performs predetermined arithmetic processing. The current position acquisition means for acquiring the current position of the user is configured. For example, the GPS system 103 can detect latitude / longitude and the absolute azimuth (east / west / south / north) at the current position as information on the current position of the user (current position information).

  The storage unit 105 is configured by a storage medium such as a hard disk or a nonvolatile memory, and stores road map information. This road map information is used, for example, to calculate a route connecting the current position and the destination based on the current position information of the user and the destination information input by the operation unit 106.

  As shown in FIG. 1, the operation unit 106 includes six switches 106a to 106f, and the user inputs destination information and adjusts the time by operating these switches.

  The display unit (liquid crystal display screen) 107 displays the absolute azimuth at the current position based on the detection results of the tilt sensor 101 and the azimuth sensor 102. For example, when holding the watch body so that the surface of the watch body 10 is horizontal with respect to the ground, which absolute direction corresponds to the four directions (3 o'clock, 6 o'clock, 9 o'clock, 12 o'clock) Indicates. Further, like a general navigation device, a road map, a current position, a route to a destination, and the like can be displayed, and the date and time can be displayed.

  The drive unit 108 is connected to the first and second rotating disks 109A and 109B via, for example, a gear transmission mechanism. The driving unit 108 is configured to be able to drive the first rotating plate 109A and the second rotating plate 109B independently or integrally based on drive control by the control unit 111 described later.

  The communication unit 110 transmits / receives various information via an antenna to / from an external device such as a server or a mobile phone connected to a predetermined communication network, and performs signal processing related to information transmission / reception. For example, current position information and destination information can be transmitted to an external device, a route can be calculated by the external device, and the route information can be received. In this case, since the memory | storage part 105 which memorize | stores road map information becomes unnecessary, an apparatus structure can be simplified.

  The clock unit 120 measures the current time. Based on the date and time information output from the clock unit 120, date and time display on the display unit 107 is controlled.

  The control unit 111 includes a CPU, a ROM, and a RAM. The CPU reads various programs stored in the ROM, develops them in the work area of the RAM, and executes them to control the entire operation of the wristwatch 1 and each component.

  Specifically, the control unit 111 constitutes route acquisition means for acquiring a route connecting the departure point (first point) and the destination (second point). Here, the route connecting the destination and the departure point is based on a route set in advance by the user and information on the destination and the departure point input by the operation unit 106 (destination information, departure point information). Includes the calculated route.

  For example, a route is determined based on destination information and departure point information input from the operation unit 106 and road map information stored in the storage unit 105. At this time, when the current position is set as the departure place, it is not necessary to input the departure place information.

FIG. 6 is a diagram showing an example of a state in which the wristwatch 1 shown in FIG. 1 is worn on the wrist and the route process is displayed on the display unit 107, and shows the relationship between the departure point and the destination and the route connecting them. Yes.
As shown in FIG. 6, when a starting point (current location or current position) as a first point and a destination as a second point are set, road map information including these points is referred to. Then, the route is determined according to the user's request (for example, the shortest route, less direction change, etc.). In addition, when there are a plurality of routes to reach the destination, the user may select the route.

  Further, the control unit 111 is a moving direction determining means for determining a direction in which the user should move based on the current position information acquired by the GPS system 103 and information (route information) regarding the acquired route. Is configured. For example, in FIG. 6, when guiding to the destination along the route C, if the current position of the user is P1, the moving direction is “north”, and if the current position of the user is P2, the moving direction is “ West ”.

  Or you may make it determine the direction which a user should move based on present position information and destination information. In FIG. 6, for example, when the user moves from the departure place to the destination, if the current position is the departure place, the moving direction is “almost northwest”. That is, the direction of the destination is simply guided regardless of whether or not a road actually exists. When the user wants to select a route freely, it is more effective to guide only the direction of the destination in this way.

  Further, the control unit 111 controls the drive unit 108 to rotate the first turntable 109A so that the longitudinal direction of the slit S coincides with the determined moving direction, and then moves the second turntable 109B in a predetermined direction. A drive control unit for moving the weight 109C along the slit S is configured by rotating at a constant speed. Thereby, while being able to guide the direction which should move at a user's present position, it can be guided to a destination along a predetermined course.

  In addition, the control unit 111 constitutes an operation detection unit for detecting that an operation for starting route guidance (guidance start switch) is performed by the operation unit 106, and the first operation is performed when the guidance start switch is turned on. The first and second turntables 109A and A09B are rotated. In the present embodiment, the first operation is performed not only when the operation unit 106 performs an operation for starting azimuth guidance but also when the tilt sensor 101 is turned on (the watch body 10 is horizontal to the ground). And the second turntables 109A and 109B are rotated. That is, since the rotating disk is driven only when the user desires the direction guidance, it is possible to prevent the weight 109C from moving in a dark state and deteriorating the wearing feeling.

  FIG. 7 is a flowchart illustrating an example of the direction guidance process according to the present embodiment. This flowchart is realized by the CPU of the control unit 111 executing a program related to direction guidance. 8 to 11 are explanatory views showing the moving state of the weight 109C when the first rotating disk 109A is fixed and the second rotating disk 109B is rotated.

In step S101, departure point information indicating the first point is input or acquired. For example, the departure point information is input by the user operating the operation unit 106. When the current position is set as the departure place, the current position information input from the GPS system 103 is acquired as the departure place information.
In step S <b> 102, the user inputs or acquires target information by operating the operation unit 106. In steps S101 and S102, the departure point information and the destination information can be input with, for example, latitude / longitude, address, facility name, postal code, telephone number, and other codes that can specify the position on the map. . Further, it may be possible to input by selecting a desired one from a preset starting point or destination.

  In step S103, corresponding road map information is acquired based on the departure point information and destination information acquired in steps S101 and S102. That is, road map information including the departure place and the destination is acquired.

In step S104, a route is determined based on the destination information, departure point information (current position information), and road map information (see FIG. 6).
In step S105, the current position is detected by the GPS system 103, and the latitude / longitude and the absolute direction of the current position are acquired as current position information. This current position information is acquired at regular time intervals and stored in the RAM. Based on the trajectory of the current position information stored in the RAM, it is possible to calculate the traveling direction of the user.

  In step S106, the heading to be moved is determined based on the departure point information indicating the first point input in step S101 or the current position information acquired in step S105 and the route information determined in step S104. . For example, in FIG. 6, the moving direction at the point P1 is “north”, and the moving direction at the point P2 is “west”. Here, the moving direction may be expressed by a relative direction based on the traveling direction of the user.

  In step S107, it is determined whether or not the tilt switch or the guidance start switch is turned on, that is, whether or not the watch body 10 is horizontal with respect to the ground. If the watch body 10 is horizontal with respect to the ground, the process proceeds to step S108, and if not, the process proceeds to step S105.

  In step S108, the azimuth sensor 102 acquires the azimuth in which the watch main body 10 is facing. Since the timepiece main body 10 is horizontal with respect to the ground, the direction of the timepiece main body 10 at 3 o'clock, 6 o'clock, and 9 o'clock is detected by detecting the direction indicated by a specific direction (for example, 12 o'clock) in the board surface. The direction indicated by the 12 o'clock direction is known.

  In step S109, the first and second turntables 109A and 109B are integrally driven to rotate so that the longitudinal direction of the slit faces the moving direction determined in step S106. Specifically, based on the direction in which the slit S of the first turntable 109A is currently facing and the determined moving azimuth, the amount of rotation is determined and the first and second turntables are determined. 109A and 109B are integrally rotated.

  For example, when the moving azimuth is “north” and the azimuth in the 12 o'clock direction of the watch body 10 acquired in step S108 is “north”, the first and second rotating disks 109A and 109B are moved to the positions shown in FIG. It is rotated integrally. That is, the first turntable 109A is rotated so that the longitudinal direction of the slit S faces north, and the second turntable 109B is rotated integrally with the first turntable 109A. Therefore, the starting point a of the first guide groove D1 And the slit S cross each other. Further, the weight 109 </ b> C is located at the peripheral edge S <b> 1 of the slit S.

In step S110, only the second turntable 109B is rotationally driven at a constant speed clockwise, and the weight 109C is moved along the slit S.
For example, when the second turntable 109B is rotated by 40 ° from the state shown in FIG. 8, the state transitions to the state shown in FIG. In other words, the slit S intersects the end point (start point of the second guide groove) b of the first guide groove D1. At this time, the weight 109C moves at once from the peripheral edge S1 of the slit S to the central edge S2.

  Furthermore, when the second turntable 109B is rotated by 40 ° (80 ° from the start of rotation), the state changes to the state shown in FIG. 10, and the first intermediate point b1 portion of the second guide groove D2 and the slit S1 intersect. It becomes. Furthermore, when the second turntable 109B is rotated by 80 ° (160 ° from the start of rotation), the state changes to the state shown in FIG. 11, and the third intermediate point b3 of the second guide groove D2 and the slit S intersect. . At this time, the weight 109C slowly moves from the center side end S2 of the slit S to the peripheral side end S1.

  Further, the second turntable 109B is rotated, and the first guide groove D1 between cd and the second guide groove D2 between da and the slit S intersect with each other, and the state returns to the state shown in FIG. . At this time, the weight 109C moves from the peripheral edge S1 of the slit S to the central edge S2 at a stretch, and then slowly moves from the central edge S2 to the peripheral edge S1.

  FIG. 12 is an explanatory diagram showing the displacement of the weight 109C when the second turntable 109B is rotated once from the state shown in FIG. In FIG. 12, since the displacement of the weight 109C is represented by a straight line, it appears that the weight 109C moves in the first guide groove D1 and the second guide groove D2 at equal speeds v1 and v2, respectively. It is obvious that the magnitude of the speed is not constant because the direction of the speed changes from the center side to the outside or from the outside to the center side. That is, FIG. 12 shows that the speed at which the weight 109C moves at the intersection of the first guide groove D1 and the slit S is higher than the speed at which the weight 109C moves at the intersection of the second guide groove D2 and the slit S. It only shows.

  In this way, the weight 109C moves at high speed along the slit S toward the center of each of the first and second rotating disks 109A and 109B (for example, from the 12 o'clock position to the 6 o'clock position in FIG. 9). When the weight 109C moves along the slit S at a high speed), the user wearing the wristwatch 1 feels the fluctuation of the center of gravity of the watch body 10 remarkably. As a result, the user is pulled in the direction opposite to the moving direction of the weight 109C (the direction from the 6 o'clock position to the 12 o'clock position in FIG. 9), that is, the moving direction (“north” in FIG. 9). Receive a sense of being. In the present embodiment, when the second turntable 109B is rotated once, the user feels that the arm is pulled twice. If the second turntable 109B is continuously rotated, the user can be continuously given a feeling that the arm is pulled, so that the moving direction can be reliably guided.

  As described above, according to the azimuth guidance processing according to the present embodiment, the azimuth to be moved at the current position can be directly guided to the user, and a route to the destination can be guided. Further, by displaying the absolute azimuth in a specific direction on the display unit 107, the user can know which azimuth is the moving azimuth.

  Further, since the first turntable 109A provided with the slit S indicating the moving direction can be rotated in an arbitrary direction, there is an advantage that an arbitrary direction can be suggested regardless of the direction of the watch body 10.

  In addition, since the suggested direction can be changed by 180 ° simply by reversing the rotation direction of the second rotary disk 109B provided with the groove D for moving the weight 109C, the slit S of the first rotary disk 109A is currently facing. It is not always necessary to match the moving direction (the direction from the center toward the peripheral side) with the moving direction. For example, when the slit S is currently facing “north” and suggests the moving direction “south”, it is not necessary to rotate the first rotating disk 109A, and the second rotating disk 109B is rotated counterclockwise. Thus, the moving direction can be guided. As a result, the first turntable 109A can be brought into a desired state more quickly, so that the time required to guide the moving direction can be shortened.

  As mentioned above, although the invention made by this inventor was concretely demonstrated based on embodiment, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

The body-mounted electronic device according to the present invention is not limited to the wristwatch shown in the above embodiment, and can be applied to an electronic device that directly or indirectly contacts a part of the user's body.
For example, as shown in FIG. 13, the present invention can be applied to a cane 2 having a longitudinal support 23 for providing a main body and a handle 22 gripped by the user at the upper end of the support 23. Specifically, the apparatus main body 21 of the body-mounted electronic device is mounted on the handle 22. When the cane 2 is used, the lower end of the column 23 is grounded. At this time, the handle 22 and the apparatus main body 21 are horizontal with respect to the ground, so that the orientation at the current position can always be acquired. Therefore, the user can receive direction guidance without being aware of the state of the cane. Further, the azimuth guidance process may be executed when the cane 2 is separated from the ground for a certain time.

  The body-mounted electronic device according to the present invention can also be applied to a mobile phone, a PDA (Personal Digital Assistant), and the like. In this case, the user feels the traction force from the body-mounted electronic device with the fingertip.

In the above-described embodiment, the traction force that pulls the user's arm is generated by the two rotary disks 109A and 109B and the weight 109C. However, the traction force may be generated by other mechanisms. Good.
For example, a crank-slider mechanism shown in FIG. 14 can be used. In other words, in FIG. 14, one end of the first connecting rod 32 is connected to the crankshaft 31, and the connecting rod 32 is attached so as to pass through the fixed point F regardless of the rotational movement of the crankshaft 31. Further, the other end of the first connecting rod 32 and one end of the second connecting rod 33 are rotatably connected to each other, and the slider 34 is fixed to the other end of the second connecting rod 33.

In such a crank-slider mechanism, when the crankshaft 31 is rotationally driven, the slider 34 reciprocates along the axis, but the change in acceleration when the direction of movement of the slider 34 changes to the crank side is extremely different. Can be bigger. Using this change in acceleration, it is possible to generate a traction force in one direction.
It is also possible to generate a traction force by using a so-called cam mechanism that attaches a plate having an arbitrary shape to a rotating shaft and transmits movement using contact between the plate and other components.

Further, the shape of the slit S formed in the first rotating disk 109A and the shape of the groove D formed in the second rotating disk 109B are not limited to those shown in the above embodiment.
For example, a set of turntables shown in FIGS. 15 and 16 can be used. That is, as shown in FIG. 15, the slit S is formed in the first turntable 109A so that the end is close to the peripheral edge of the turntable. In addition, as shown in FIG. 16, the guide groove D is formed in the second rotating disk 109 </ b> B so as to be substantially elliptical. By adopting such a shape, the maximum amount of movement of the weight 109C held between the slit S and the groove D is close to the diameter of the rotating disk, and becomes larger than the case shown in the above embodiment. A large traction force can be generated.

  Furthermore, instead of the slit S, a groove extending in one direction may be formed in the first rotating disk 109A. In addition, the groove D formed in the second rotating disk 109B has a linear polygonal line shape for the sake of simplicity of description, but actually has a curved shape calculated so that the weight 109C can be moved smoothly. Is desirable.
