  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram showing a schematic configuration of a mobile terminal device according to Embodiment 1 of the present invention. In the figure, the mobile terminal device 1 of the present embodiment has a walking navigation function, and includes a position information acquisition unit 11, a central processing unit 13, an operation unit 14, a communication control unit 15, and a display. Unit 16, direction sensor unit 17, map information storage unit 18, and vibration pattern storage unit 19.

  The position information acquisition unit 11 includes a position information reception unit 111 and a position information analysis unit 112. The position information reception unit 111 transmits orbit information transmitted from a GPS (Global Positioning System) satellite 30 that is an SPS (Satellite Positioning System). The position information analysis unit 112 analyzes the trajectory information received by the position information reception unit 111 and acquires the position information. The operation unit 14 includes a plurality of keys such as a dial key, a transmission / reception key, a power / end key, a center key, and a cursor key, vibration elements provided corresponding to the plurality of keys, and each vibration element. And a vibrating portion 1410 to be operated.

  FIG. 2 is a front view showing the mobile terminal device 1 of the present embodiment. As shown in the figure, the operation unit 14 is provided below the central part of the apparatus main body. In addition, a vibration element 1411 is provided so as to overlap each of the plurality of keys 141. The vibration unit 1410 vibrates the vibration element 1411 corresponding to the pattern given from the calculation unit 132 (details will be described later) of the central processing unit 13. The vibration element 1411 is, for example, a small motor.

  The communication control unit 15 performs bidirectional communication with the wireless communication network 50 using a communication protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol). A server 40 capable of distributing map information is connected to the wireless communication network 50. The display unit 16 includes a display such as a liquid crystal display or an organic EL display (Organic Electroluminescence Display), and performs various displays when the mobile terminal device 1 is used. As shown in FIG. 2, the display unit 16 is provided above the central part of the apparatus main body. The direction sensor unit 17 includes a magnetic sensor, an acceleration sensor, an angular velocity sensor, or the like, and detects the orientation of the mobile terminal device 1. The map information storage unit 18 stores map information. The vibration pattern storage unit 19 stores a pattern for notifying the user of the front, right, and left directions of the mobile terminal device 1 by vibration.

  The central processing unit 13 includes a map information acquisition unit 131 and a calculation unit 132 that acquire map information. The map information acquisition unit 131 acquires map information stored in the map information storage unit 18. The map information acquisition unit 131 uses the communication control unit 15 to access the wireless communication network 50 and acquires map information from the server 40 connected to the wireless communication network 50. When the map information is acquired from the server 40, the acquired map information is stored in the map information storage unit 18. By making it possible to acquire map information via the wireless communication network 50, it is possible to always obtain the latest map data and to detect without missing a new obstacle. Moreover, by having the map information storage part 18, map information can be acquired immediately when needed, and the speed concerning the detection of an obstacle can be improved.

  The calculation unit 132 is based on the position information acquired by the position information acquisition unit 11, the orientation of the mobile terminal device 1 detected by the direction sensor unit 17, and the map information acquired by the map information acquisition unit 131. Obstacles that are present in the direction of right, left or right before the direction of travel of 1 are detected. Further, the calculation unit 132 is based on the position information acquired by the position information acquisition unit 11, the orientation of the mobile terminal device 1 detected by the direction sensor unit 17, and the map information acquired by the map information acquisition unit 131. The distance to the obstacle existing in the front, right or left direction of the traveling direction of the terminal device 1 is calculated. In addition, when the calculation unit 132 detects an obstacle and calculates the distance to the obstacle, the calculation unit 132 generates a pattern for vibrating the vibration element 1411 corresponding to the detected direction of the obstacle. Is read out and given to the vibration unit 1410 of the operation unit 14 and the distance to the obstacle is given.

  The vibration unit 1410 of the operation unit 14 vibrates the vibration element 1411 corresponding to the pattern given from the calculation unit 132 and vibrates the vibration element 1411 with an intensity corresponding to the distance to the obstacle. In this case, when the calculation unit 132 detects an obstacle that exists in the right front or left front direction of the traveling direction of the mobile terminal device 1, the vibration unit 1410 detects that the obstacle is within a predetermined angle range with reference to the traveling direction ( For example, when the angle is 45 degrees, only the previous vibration element 1411 is vibrated. In this way, by defining the predetermined angular range as the forward direction with reference to the traveling direction, the previous vibration element 1411 and the left or right vibration element 1411 do not operate simultaneously, and an erroneous determination is made to the user. I will not let you.

Next, the operation of the mobile terminal device 1 of the present embodiment will be described.
FIG. 3 is a flowchart for explaining the operation of the mobile terminal device 1 of the present embodiment. 4, 5, and 7 to 14 are diagrams for explaining vibration patterns of the mobile terminal device 1 according to the present embodiment. Hereinafter, in the description of the operation, reference is made to the vibration patterns shown in FIGS. 4, 5, and 7 to 14.

  In FIG. 3, the calculation unit 132 first determines whether or not the vehicle is on the road based on the position information acquired by the position information acquisition unit 11 and the map information acquired by the map information acquisition unit 131 (step S201). If not on the road, the “out-route pattern” is read from the vibration pattern storage unit 19 and applied to the vibration unit 1410 of the operation unit 14 (step S202).

  FIG. 4 is a diagram showing a vibration state by the “out-route pattern”. Referring to FIG. 2, the “out-route pattern” refers to the vibration elements 1411-1, 1411-4, 1411-6 in the keys 141-1, 141-4, 141-6, 141-7, 141-9, 141-12. , 1411-7, 1411-9, 1411-12 vibrate simultaneously. This vibration represents an approximate “x” (letter) character. The user can feel “x” by placing the palm of the hand against the operation unit 14 and can grasp that the user has deviated from the route.

When the calculation unit 132 determines that the road is on the road in the determination in step S201, the calculation unit 132 determines the distance to the next guide point (step S203). In this case, the calculation unit 132 obtains the distance to the next guide point based on the position information acquired by the position information acquisition unit 11 and the map information acquired by the map information acquisition unit 131. In this determination, if the distance X to the next guide point is greater than or equal to the distance a ₁ (X ≧ a ₁ ), the calculation unit 132 reads “pattern A1” from the vibration pattern storage unit 19 and While giving to the vibration part 1410, the distance calculated | required now is also given to the vibration part 1410 of the operation part 14 (step S204-1).

  (A) of FIG. 5 is a figure which shows the vibration state by "pattern A1". Referring to FIG. 2, in “pattern A1”, the vibration elements 1411-1 to 1411-18 in all the keys 141-1 to 141-17 vibrate simultaneously. At this time, since the distance to the next guide point is the longest among the distances determined in this processing, the vibrating elements 1411-1 to 1411-18 are vibrated with the minimum strength.

In the determination of step S203 in FIG. 3, if the distance X to the next guide point is a distance a ₁ or less and a ₂ or more (a ₁ ≧ X ≧ a ₂ ), the calculation unit 132 stores the vibration pattern. “Pattern A2” is read from the unit 19 and given to the vibration unit 1410 of the operation unit 14, and the calculated distance is also given to the vibration unit 1410 of the operation unit 14 (step S 204-2).

  FIG. 5B is a diagram illustrating a vibration state by “pattern A2”. In “Pattern A2”, as in “Pattern A1” described above, the vibrating elements 1411-1 to 1411-18 in all the keys 141-1 to 141-17 vibrate simultaneously. At this time, since the distance to the next guide point is the second largest among the distances determined in this process, the vibrating elements 1411-1 to 1411-18 are vibrated more strongly than in the case of “pattern A1”. .

If the distance X to the next guide point is not more than the distance a _{2 and not} less than a ₃ (a ₂ ≧ X ≧ a ₃ ) in the determination in step S203 of FIG. 3, the calculation unit 132 stores the vibration pattern. “Pattern A3” is read from the unit 19 and given to the vibration unit 1410 of the operation unit 14, and the obtained distance is also given to the vibration unit 1410 of the operation unit 14 (this step is not shown).

  (C) of FIG. 5 is a figure which shows the vibration state by "pattern A3". In the “pattern A3”, the vibration elements 1411-1 to 1411-18 in all the keys 141-1 to 141-17 vibrate simultaneously at the same time as the “pattern A1” described above. At this time, since the distance to the next guide point is the third farthest in the distance determined in this process, the vibration elements 1411-1 to 1411-18 are vibrated more strongly than in the case of “pattern A2”. .

Similarly to the above, within the range of a ₃ ≧ X ≧ a ₄ , a ₄ ≧ X ≧ a ₅ ,..., A _n−2 ≧ X ≧ a _n−1 , this corresponds to the distance X to the next guide point. A pattern (any one of the patterns A4 to An-1) is determined, and the vibration elements 1411-1 to 1411- in all the keys 141-1 to 141-17 with the strength corresponding to the pattern and the distance X are determined. 18 is vibrated simultaneously.

If the distance X to the next guide point in the determination in step S203 of FIG. 3 is _{equal to} or less than the distance a _n−1 and _{equal to} or greater than an (a _n−1 ≧ X ≧ a _n ), Then, “pattern An” is read from the vibration pattern storage unit 19 and given to the vibration unit 1410 of the operation unit 14, and the calculated distance is also given to the vibration unit 1410 of the operation unit 14 (step S 204-n).

Next, the computing unit 132 determines the direction of the obstacle (“front”, “left”, “right”, “back”) and the distance Y to the obstacle (step S205). In this case, the calculation unit 132 obtains the distance to the obstacle based on the position information acquired by the position information acquisition unit 11 and the map information acquired by the map information acquisition unit 131. The computing unit 132 also determines the direction of the obstacle from the direction of the device 1 detected by the direction sensor unit 17. In these determinations, the direction of the obstacle is "front" (step S206-1), if and _{b h2} over the distance Y to the obstacle is less than the distance _{b h1 (b h1> Y ≧} b h2), operation The unit 132 reads “pattern Bh1” from the vibration pattern storage unit 19 and gives it to the vibration unit 1410 of the operation unit 14, and also gives the currently obtained distance to the vibration unit 1410 of the operation unit 14 (step S207-h1).

  FIG. 6 is a diagram illustrating a pattern for notifying the direction of an obstacle. In the figure, when the obstacle is “in front” of the present apparatus 1, “pattern Bhn” is used. In this “pattern Bhn”, referring to FIG. 2, the vibration elements 1411-13, 1411-15, and 1411-17 in the keys 141-13, 141-15, and 141-16 located on the upper end side of the operation unit 14 are simultaneously Vibrate.

  When the obstacle is “left” of the apparatus 1, “pattern Bin” is used. In the “pattern Bin”, referring to FIG. 2, the vibration elements 1411-1-14, 1411-1, 1411- in the keys 141-14, 141-1, 141-2, 141-3 located on the left end side of the operation unit 14 are illustrated. 2, 1411-3 vibrate simultaneously.

  Further, when the obstacle is on the “right” side of the apparatus 1, “pattern Bjn” is used. In “Pattern Bjn”, referring to FIG. 2, the vibration elements 1411-18, 1411-9, and 1411-in the keys 141-17, 141-9, 141-10, and 141-11 located on the right end side of the operation unit 14. 10, 1411-11 vibrate simultaneously.

  When the obstacle is “after” the present apparatus 1, “pattern Bkn” is used. In the “pattern Bkn”, referring to FIG. 2, the vibration elements 1411-4, 1411-8, and 1411-12 in the keys 141-4, 141-8, and 141-12 located on the lower end side of the operation unit 14 vibrate simultaneously. To do.

  In each of “Pattern Bhn”, “Pattern Bin”, “Pattern Bjn”, and “Pattern Bkn”, the strength of vibration of the vibration element 1411 changes according to the distance to the obstacle. When it is farthest, it vibrates with the minimum strength, and gradually becomes stronger as it gets closer, and when it is the nearest, it vibrates with the maximum strength.

  FIG. 7 is a diagram illustrating a vibration state by “pattern Bh1”, “pattern Bh2”, and “pattern Bh3”. The vibration becomes stronger in the order of “pattern Bh1” → “pattern Bh2” → “pattern Bh3”.

  FIG. 8 is a diagram illustrating a vibration state by “pattern Bi1”, “pattern Bi2”, and “pattern Bi3”. The vibration becomes stronger in the order of “pattern Bi1” → “pattern Bi2” → “pattern Bi3”.

  FIG. 10 is a diagram illustrating a vibration state by “pattern Bk1”, “pattern Bk2”, and “pattern Bk3”. The vibration becomes stronger in the order of “pattern Bk1” → “pattern Bk2” → “pattern Bk3”.

  Returning to the flowchart of FIG. 3, in step S <b> 207-h <b> 1, the calculation unit 132 reads “pattern Bh <b> 1” from the vibration pattern storage unit 19 and gives it to the vibration unit 1410 of the operation unit 14. The vibration unit 1410 provides the vibration elements 1411-13, 1411-15, and 1411-17 in the keys 141-13, 141-15, and 141-16 located on the upper end side of the operation unit 14. Simultaneously vibrate with minimum strength. Then, when the process of step S207-h1 is completed, the process returns to step S201.

Further, in the determination of step S205, in the direction of the obstacle is "before", if the distance Y to the obstacle and is less than the distance _{b h2 b h3} or _{(b h2> Y ≧ b h3} ), the arithmetic unit 132 Then, “pattern Bh2” is read from the vibration pattern storage unit 19 and given to the vibration unit 1410 of the operation unit 14, and the distance obtained now is also given to the vibration unit 1410 of the operation unit 14 (step S207-h2). Accordingly, the vibration unit 1410 causes the vibration elements 1411-13, 1411-15, and 1411-17 in the keys 141-13, 141-15, and 141-16 located on the upper end side of the operation unit 14 to be “pattern Bh1”. Vibrate more strongly. Then, when the process of step S207-h2 is completed, the process returns to step S201.

Similarly to the above, a pattern corresponding to the distance Y to the obstacle within the range of b _h3 > Y ≧ b _h4 , b _h4 > Y ≧ b _h5 ,..., B _hn−2 > Y ≧ b _hn−1 (“pattern” Any one of Bh3 "to" pattern Bhn-2 ") is determined, and the vibration elements 1411-13 in the keys 141-13, 141-15, 141-16 with the strength corresponding to the pattern and the distance Y are determined. 1411-15 and 1411-17 are vibrated simultaneously.

Then, in the judgment of step S205, in the direction "before" the obstacle, if the distance Y to the obstacle distance _{b hn-1} and less than _{b hn} or _{(b hn-1> Y ≧} b hn), The calculation unit 132 reads “pattern Bhn” from the vibration pattern storage unit 19 and gives it to the vibration unit 1410 of the operation unit 14 and also gives the obtained distance to the vibration unit 1410 of the operation unit 14 (step S207-hn). Accordingly, the vibration unit 1410 vibrates the vibration elements 1411-13, 1411-15, and 1411-17 in the keys 141-13, 141-15, and 141-16 located on the upper end side of the operation unit 14 with the maximum strength. Let Then, when step S207-hn is completed, the process returns to step S201.

  The above is the case where the direction of the obstacle is “front”, but the pattern is different in any case where the direction of the obstacle is “left”, “right”, “back”, but “front” The same processing is performed.
