Summary of the Invention

Problems to be Solved by the Invention

[0004] There is room for improvement in Patent Document 1 above with regard to making it difficult for a user who performs at least one of an input operation on a terminal and a visual recognition operation of a display unit to feel discomfort.

[0005] In consideration of the above facts, an object of the present invention is to obtain an operation terminal control device that makes it difficult for a user who performs at least one of an input operation on an operation terminal and a visual recognition operation of a display unit to feel discomfort.

Means for Solving the Problems

[0006] The operation terminal control device according to claim 1 includes an angle detection unit that detects a first angle, which is a relative angle with respect to a first predetermined direction of a display unit capable of displaying an image provided on an operation terminal that can be held by a user, and a control unit that restricts at least one of an input operation by the user on an input unit provided on the operation terminal and a display operation of the display unit when the first angle is not within a predetermined first range, compared to when the first angle is within the first range. The system includes a gaze detection unit provided in the vehicle for detecting the direction of the user's gaze, and when the first angle is not within the first range and the second angle, which is the relative angle of the gaze direction to a second predetermined direction, is not within a predetermined second range, the control unit restricts at least one of the input operation and the display operation of the display unit compared to when the first angle is within the first range. Operation terminal control device.

[0007] In the operation terminal control device of claim 1, when the first angle is not within the first range, at least one of the user's input operation to the input unit and the display operation of the display unit is restricted by the control unit compared to when the first angle is within the first range. Therefore, when the first angle is not within the first range, the likelihood of the user performing at least one of the input operation to the operation terminal and the viewing operation of the display unit is low. Consequently, the operation terminal control device of claim 1 is less likely to cause discomfort to the user performing at least one of the input operation to the operation terminal and the viewing operation of the display unit.

[0008] The operation terminal control device according to claim 2 is the invention according to claim 1, wherein the display unit is capable of displaying game content and the control unit adds scoring elements to the game when the first angle is within the first range.

[0009] In the operation terminal control device of claim 2, the control unit adds a scoring element to the game when the first angle is within the first range. Therefore, there is a high probability that the user will perform at least one of the following actions: inputting to the operation terminal and viewing the display unit, while the first angle is within the first range.

[0010] The operation terminal control device according to claim 3 is Claim 1 stated In the present invention, when the display unit is capable of displaying game content and the first angle is not within the first range, the control unit adds a penalty element to the game.

[0011] In the operation terminal control device of claim 3, when the first angle is not within the first range, the control unit adds a penalty element to the game. Therefore, it is unlikely that the user will perform at least one of the input operation to the operation terminal and the viewing operation of the display unit when the first angle is not within the first range.

[0012] The operation terminal control device according to claim 4 is Claim 1 statedIn the invention of the invention, the display unit is capable of displaying game content, and when the first angle is not within the first range, the control unit makes the number of deduction elements to be added to the game greater than the number of addition elements to be added to the game, compared to when the first angle is within the first range.

[0013] In the operation terminal control device of claim 4, when the first angle is not within the first range, the control unit increases the number of penalty elements added to the game compared to when the first angle is within the first range. Therefore, the likelihood of the user performing at least one of the input operation to the operation terminal and the viewing operation of the display unit when the first angle is not within the first range is low.

[0014] Claim 5 The operating terminal control device, in the invention described in claim 1, is such that -α° ≤ the first range ≤ +α°, where α is any value between 20 and 40, and 0° ≤ the second range ≤ +β°, where β is any value between 20 and 40. .

[0015] Operation terminal control device according to claim 1 When the first angle is not within the first range and the second angle is not within a predetermined second range, the control unit restricts at least one of the user's input operations and the display operation of the display unit, compared to when the first angle is within the first range. In other words, when the first angle is not within the first range and the second angle is within a predetermined second range, the control unit does not restrict the user's input operations or the display operation of the display unit. Therefore, Claim 1 The control device for the operating terminal does not unnecessarily restrict at least one of the user's input operations and the display operations of the display unit. [Effects of the Invention]

[0016] As described above, the operating terminal control device according to the present invention has the excellent effect of making it less likely for the user performing at least one of the input operations on the operating terminal and the viewing operations on the display unit to feel uncomfortable.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, an embodiment of an operation terminal control device 10 (hereinafter, control device 10) according to the present invention will be described with reference to the accompanying drawings. The control device 10 of the embodiment is applied to a vehicle 12 and an operation terminal 40. In each figure, an arrow FR appropriately shown indicates the front of the vehicle, which is the front side in the vehicle longitudinal direction, and an arrow UP indicates the upper side of the vehicle, which is the upper side in the vehicle vertical direction.

[0019] In a passenger compartment 14A, which is an internal space of a vehicle body 14 of the vehicle 12, a pair of left and right front seats 16 and a single rear seat 18 are provided (only the left front seat 16 in FIG. 1 is shown). The rear seat 18 is located behind the front seat 16. A steering wheel 21 is provided at a position on the right side of the center in the left-right direction of a dashboard 20 provided at the front end of the passenger compartment 14A. That is, the right front seat 16 is the driver's seat, and the left front seat 16 is the passenger seat. As shown in FIG. 1, a passenger (user) P1 is seated on the left front seat 16, and a passenger (user) P2 is seated on the rear seat 18.

[0020] <s As shown in FIG. 1, an ECU 23 and a line-of-sight sensor 32 are provided on the vehicle body 14.

[0021] As shown in Figure 2, the ECU 23 consists of a CPU (Central Processing Unit: processor) 24, ROM (Read Only Memory) 25, RAM (Random Access Memory) 26, storage 27, communication interface 28, and input / output interface 29. The CPU 24, ROM 25, RAM 26, storage 27, communication interface 28, and input / output interface 29 are connected to each other via a bus 30 so that they can communicate with one another. The ECU 23 can obtain date and time information from a timer (not shown).

[0022] The CPU 24 is the central processing unit, which executes various programs and controls various components. Specifically, the CPU 24 reads programs from the ROM 25 or storage 27 and executes them using the RAM 26 as its working area. The CPU 24 controls each component and performs various calculations (information processing) according to the programs recorded in the ROM 25 or storage 27.

[0023] ROM25 stores various programs and data. RAM26 temporarily stores programs or data as a working area. Storage27 consists of a storage device such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) and stores various programs and data. Communication I / F28 is an interface that can communicate with devices located outside the vehicle 12. For example, communication I / F28 can wirelessly communicate with the communication I / F49 of the operation terminal 40. Communication I / F28 uses communication standards such as Bluetooth® and Wi-Fi®. Furthermore, communication I / F28 can communicate with an ECU other than the ECU23 located in the vehicle 12 via an external bus. Input / Output I / F29 is an interface for communicating with various devices.

[0024] The gaze sensor 32 is connected to the input / output I / F 29. The gaze sensor 32 in this embodiment includes an infrared illumination device and an infrared camera. The infrared illumination device irradiates infrared light onto the faces P1A, P2A of the occupants P1 and P2 and their surroundings, and the infrared camera captures images of the faces P1A, P2A of the occupants P1 and P2 and their surroundings.

[0025] Figure 3 shows an example of the functional configuration of the ECU 23 in a block diagram. The ECU 23 has a gaze detection unit 231 as part of its functional configuration. When the gaze detection unit 231 receives subject image data from the gaze sensor 32, it processes this subject image data. The gaze detection unit 231 then calculates (detects) the directions of the gazes ED1 and ED2 of the occupants P1 and P2 using methods disclosed, for example, in Japanese Patent Publication No. 2002-83400 and Japanese Patent Publication No. Hei 7-61257. The information regarding the directions of the gazes ED1 and ED2 detected by the gaze detection unit 231 is wirelessly transmitted by the communication I / F 28 to the communication I / F 49 of the operation terminal 40.

[0026] Crew members P1 and P2 are each holding the operating terminal 40 shown in Figure 1 with their respective hands P1B and P2B. The operating terminal 40 in this embodiment is a smartphone. The operating terminal 40 has a flat display unit (input unit) 41 with a touch panel, and a gyro sensor 42 (see Figure 2). The display unit 41 is provided on the surface of the operating terminal 40. As shown in Figure 2, the hardware configuration 44 of the operating terminal 40 includes a CPU 45, ROM 46, RAM 47, storage 48, communication I / F 49, and input / output I / F 50. The CPU 45, ROM 46, RAM 47, storage 48, communication I / F 49, and input / output I / F 50 are connected to each other so as to be able to communicate with each other via a bus 51. The functions of CPU45, ROM46, RAM47, storage48, communication I / F49, and I / O I / F50 are the same as those of CPU24, ROM25, RAM26, storage27, communication I / F28, and I / O I / F29, respectively. Game applications and motion sickness prevention applications are installed in ROM46 or storage48.

[0027] Figure 4 shows a block diagram illustrating an example of the functional configuration of the hardware configuration 44. The hardware configuration 44 has the following functional configuration: a first angle detection unit (angle detection unit) 451, a second angle detection unit (angle detection unit) 452, an input control unit (control unit) 453, a display control unit (control unit) 454, and a game control unit (control unit) 455. The first angle detection unit 451, the second angle detection unit 452, the input control unit 453, the display control unit 454, and the game control unit 455 are realized by the CPU 45 reading and executing a program stored in the ROM 46. The first angle detection unit 451, the second angle detection unit 452, the input control unit 453, and the display control unit 454 function when the motion sickness prevention application is running.

[0028] The first angle detection unit 451 detects a first angle θ1 of the surface of the display unit 41, which is a flat surface, based on the detection value of the gyro sensor 42. As shown in Figure 1, the first angle θ1 is the angle between the vertical direction (first predetermined direction) DV and the surface of the display unit 41 in a side view of the operation terminal 40. Furthermore, the first angle detection unit 451 determines whether the detected first angle θ1 is within a predetermined first range AR1. In this embodiment, the first range AR1 is -α° ≤ first range AR1 ≤ +α°. Here, a + (plus) angle is the angle in front of the vertical direction DV in a side view of the operation terminal 40, and a - (minus) angle is the angle behind the vertical direction DV in a side view of the operation terminal 40. Here, α is, for example, any value between 20 and 40. Note that α may also be any value between 25 and 35. However, α is not limited to this magnitude.

[0029] The second angle detection unit 452 detects the second angle θ2 of occupants P1 and P2 based on information regarding the direction of lines of sight ED1 and ED2 received by the communication I / F 49 from the vehicle's communication I / F 28. As shown in Figure 1, the second angle θ2 is the angle formed by the horizontal direction (second predetermined direction) DH and the lines of sight ED1 and ED2 in a side view of the vehicle 12. Furthermore, the second angle detection unit 452 determines whether the detected second angle θ2 is within a predetermined second range AR2. In this embodiment, the second range AR2 is 0° ≤ second range AR2 ≤ +β°. Here, the + (plus) angle is the angle below the horizontal direction DH. Here, β is, for example, any value between 20 and 40. However, β may also be any value between 25 and 35. However, β is not limited to this magnitude.

[0030] The input control unit 453 determines whether a predetermined limiting condition is met. The limiting condition is met when the first angle θ1 is not within the first range AR1 and the second angle θ2 is not within the second range AR2. Furthermore, when it is determined that the limiting condition is met, the input control unit 453 executes limiting control. That is, the input control unit 453 restricts the input operations to the display unit 41 (touch panel) by the occupants P1 and P2. In this specification, restricting input operations means that all input operations to the display unit 41 are disabled, or that some input operations to the display unit 41 are disabled.

[0031] If all input operations to the display unit 41 are disabled, the CPU 45 will not perform any calculations resulting from the input operations to the display unit 41. For example, if the above-mentioned game application is running on the operation terminal 40 and all input operations to the display unit 41 are disabled, no changes resulting from the input operations to the display unit 41 will occur in the running game. Also, if the input operation to the display unit 41 is a character input operation, and all input operations to the display unit 41 are disabled, the entered characters will not be displayed on the display unit 41.

[0032] If some input operations to the display unit 41 are invalid, the CPU 45 will not perform calculations resulting from these input operations. For example, consider a case where some input operations to the display unit 41 are invalid when the game application is running on the operation terminal 40. In this case, for example, an input operation to give a game character a specific weapon will be invalid, while an input operation to give money to the character will be allowed. Also in this case, for example, an operation to send an email via input to the display unit 41 will be invalid, while an operation to make a call via input to the display unit 41 will be allowed.

[0033] The display control unit 454 determines whether the above restriction conditions are met. If it determines that the restriction conditions are met, the display control unit 454 executes restriction control. That is, the display control unit 454 restricts the display operation of the display unit 41. In this specification, restricting the display operation means that all of the display operation of the display unit 41 is disabled, or that some of the display operation of the display unit 41 is disabled.

[0034] If the restriction conditions are not met, the display unit 41 performs normal display operations. For example, if the above game application is running on the operation terminal 40, the game image Img as game content will be displayed on the display unit 41, as shown in Figure 5(a).

[0035] On the other hand, if all display operations of the display unit 41 are disabled due to the fulfillment of the restriction conditions, a black or white image will be displayed across the entire display unit 41, as shown in Figure 5(b), for example. That is, if the game application is running on the operation terminal 40, the game image Img will not be displayed. However, even if all display operations are disabled, the display unit 41 may still display a message described later.

[0036] If some of the display operations of the display unit 41 are disabled, for example, the display of video on the display unit 41 is prohibited, while the display of still images on the display unit 41 is permitted.

[0037] Furthermore, depending on whether the limit conditions are met or not, the following message control and point addition / deduction control will be executed separately from the limit control.

[0038] Message control is performed as follows: When it is determined that the restriction condition is met, the display control unit 454 causes the display unit 41 to display a predetermined message. For example, as shown in Figure 5(b), the message Msb "Raise the display unit of the operation terminal and direct your gaze forward" is displayed on the display unit 41. The display control unit 454 may also display a message on the display unit 41 if the above restriction condition is met for a predetermined period of time or longer. This predetermined period is, for example, 10 seconds. However, this predetermined period is not limited to this value. Also, when it is determined that the restriction condition is not met, the display control unit 454 causes the display unit 41 to display a predetermined message. For example, as shown in Figure 5(a), the message Msa "This is the perfect tilt angle and gaze direction" is displayed on the display unit 41. The display control unit 454 may also display a message on the display unit 41 if the above restriction condition is not met for a predetermined period of time or longer. This predetermined period is, for example, 10 seconds. However, this predetermined period is not limited to this value.

[0039] The scoring control is implemented as follows:

[0040] The point addition / deduction control is executed when the motion sickness prevention application is running. Here, we assume that the game control unit 455 is executing the processing of the game application. For example, when the game control unit 455 determines that the above restriction conditions are not met, the game control unit 455 adds points to the game and does not add points that will be described later. Here, points are elements that are advantageous to the user (crew members P1 and P2). For example, elements that increase the health of the game character, elements that grant a character a predetermined weapon, and elements that grant a character money are points. The game control unit 455 may also add points if the period during which the above restriction conditions are not met continues for a predetermined time or longer. This predetermined time is, for example, 10 minutes. However, this predetermined time is not limited to this value.

[0041] Furthermore, when the game control unit 455 determines that the restriction conditions are met, the game control unit 455 adds penalty elements to the game and refrains from adding penalty elements. Here, penalty elements are elements that are disadvantageous to the user (crew members P1 and P2). For example, penalty elements include elements that reduce the health of the game characters, elements that cause the characters to discard some of their weapons, and elements that reduce the amount of money the characters possess. The game control unit 455 may also add penalty elements if the above restriction conditions remain met for a predetermined period of time or longer. This predetermined period is, for example, 5 minutes. However, this predetermined period is not limited to this value.

[0042] (Mechanism of action and effect) Next, the operation and effects of the embodiment will be described.

[0043] The following describes the processing flow performed by the CPU 45 of the operating terminal 40 using the flowchart in Figure 6. The CPU 45 repeatedly executes the processes shown in the flowchart in Figure 6 after a predetermined amount of time has elapsed. It is assumed that the communication interface 28 of the ECU 23 and the communication interface 49 of the operating terminal 40 are performing wireless communication.

[0044] First, in step S10 (the word "step" will be omitted hereafter), the CPU 45 determines whether or not the motion sickness prevention application is running.

[0045] CPU45, which determined Yes in S10, proceeds to S11 to determine whether or not the restriction condition is met.

[0046] If S11 determines "Yes," CPU45 proceeds to S12 and executes message control.

[0047] After completing the S12 process, CPU45 proceeds to S13 to determine whether or not the game application is running.

[0048] If the answer is "Yes" in S13, CPU45 proceeds to S14 and adds a scoring element to the game.

[0049] On the other hand, if the result in S11 is No, the CPU 45 proceeds to S15 and performs restriction control and message control.

[0050] After completing the S15 process, CPU45 proceeds to S16 to determine whether or not a game application is running.

[0051] If the answer is "Yes" in S16, CPU45 proceeds to S17 and adds a penalty element to the game.

[0052] When processing S14 and S17 is completed, or when No is determined in S10, 13, and 16, the CPU 45 temporarily terminates the processing of the flowchart in Figure 6.

[0053] As described above, the CPU 45 of the control device 10 in the embodiment determines that the above restriction condition is met when the first angle θ1 is not within the first range AR1 and the second angle θ2 is not within the second range AR2. When the restriction condition is met, the input operations to the display unit 41 of the operation terminal 40 and the display operations of the display unit are restricted compared to when the restriction condition is not met. Therefore, when the first angle θ1 is not within the first range AR1 and the second angle θ2 is not within the second range AR2, the likelihood of the crew members P1 and P2 performing input operations to the operation terminal 40 and viewing operations of the display unit 41 is low.

[0054] When the second angle θ2 is not within the second range AR2, occupants P1 and P2 have more difficulty perceiving the horizontal direction and recognizing their surroundings than when the second angle θ2 is within the second range AR2, so occupants P1 and P2 are less likely to feel the swaying based on their vision. On the other hand, the semicircular canals of occupants P1 and P2 sense the swaying of the vehicle 12. Therefore, when the second angle θ2 is not within the second range AR2, the brains of occupants P1 and P2 are more likely to become confused. Consequently, when input operations to the control terminal 40 and viewing operations to the display unit 41 are performed when the second angle θ2 is not within the second range AR2, occupants P1 and P2 are more likely to experience motion sickness than when input operations to the control terminal 40 and viewing operations to the display unit 41 are performed when the second angle θ2 is within the second range AR2.

[0055] In contrast, in this embodiment, when the second angle θ2 is not within the second range AR2, the input operation of the display unit 41 of the operation terminal 40 and the display operation of the display unit are restricted by the occupants P1 and P2. That is, the control device 10 makes it easier for occupants P1 and P2 to intend to adjust the direction of their lines of sight ED1 and ED2 so that the second angle θ2 is within the second range AR2 when the second angle θ2 is not within the second range AR2. Furthermore, in this embodiment, when the first angle θ1 is not within the first range AR1, the input operation of the display unit 41 of the operation terminal 40 and the display operation of the display unit are restricted by the occupants P1 and P2. That is, when the first angle θ1 is not within the first range AR1, it makes it easier for occupants P1 and P2 to intend to adjust the first angle θ1 of the operation terminal 40 so that the first angle θ1 is within the first range AR1. Furthermore, if the first angle θ1 falls within the first range AR1, the second angle θ2 is likely to fall within the second range AR2.

[0056] Therefore, the control device 10 of this embodiment is less likely to cause motion sickness in occupants P1 and P2 who perform input operations to the operation terminal 40 and visual operations to the display unit 41. In other words, the control device 10 is less likely to cause discomfort to occupants P1 and P2 who perform input operations to the operation terminal 40 and visual operations to the display unit 41. In particular, when at least one of α and β is any value between 25 and 35, occupants P1 and P2 are less likely to experience discomfort.

[0057] Furthermore, in this embodiment, when the first angle θ1 is not within the first range AR1 and the second angle θ2 is within the second range AR2, the restriction control is not performed. Therefore, the control device 10 does not unnecessarily restrict the input operations to the display unit 41 by the occupants P1 and P2, or the display operations of the display unit 41.

[0058] Furthermore, in this embodiment, when the limiting conditions are not met, points are added to the game being played on the operation terminal 40, and when the limiting conditions are met, points are deducted from the game. Therefore, crew members P1 and P2 are more likely to intend to operate the operation terminal 40 (operate the game) when the limiting conditions are not met. Consequently, in this respect as well, the control device 10 is less likely to cause discomfort to crew members P1 and P2 who perform input operations on the operation terminal 40 and visual operations on the display unit 41.

[0059] Although the control device 10 according to the embodiment has been described above, the control device 10 can be appropriately modified in design without departing from the spirit of the present invention.

[0060] For example, if the restriction condition is met, only one of the input operations to the display unit 41 of the operating terminal 40 or the display operation of the display unit 41 may be restricted.

[0061] When the condition that the first angle θ1 is not within the first range AR1 is met, the restriction condition may be satisfied regardless of the size of the second angle θ2.

[0062] When a game application is executed on the operating terminal 40 and the limiting conditions are met, scoring control may be performed such that the number of penalty elements assigned to the game is greater than the number of bonus elements assigned to the game. For example, elements that reduce the health of a game character and elements that cause the character to discard some of the weapons owned by the character may be assigned to the game as penalty elements, and elements that give money to the character may be assigned to the game as bonus elements.

[0063] The gyro sensor 42 may be omitted from the operating terminal 40, and a camera (not shown) provided on the vehicle 12 may photograph the operating terminal 40. In this case, the photographic data of the operating terminal 40 acquired by the camera is transmitted from the communication I / F 28 to the communication I / F 49, and the first angle detection unit 451 calculates the first angle θ1 based on this photographic data.

[0064] The gaze sensor 32 may be provided on the operating terminal 40 instead of the vehicle 12.

[0065] The operating terminal 40 does not have to be a smartphone. For example, the operating terminal 40 may be a tablet computer or a notebook PC. Also, if the operating terminal 40 is a notebook PC, for example, the input unit may be a keyboard. [Explanation of Symbols]
