Embodiments for Carrying Out the Invention

[0009] Embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and the description thereof will not be repeated.

[0010] (1) Configuration of the traveling display device 1 First, referring to FIGS. 1 and 2, a traveling display device 1 that detects surrounding people and displays content during or after movement will be described. FIG. 1 is a perspective view illustrating the appearance of the traveling display device 1 according to an embodiment of the present disclosure. FIG. 2 is a block diagram showing the configuration of the traveling display device 1.

[0011] As shown in FIG. 1, the traveling display device 1 includes a front display surface 14F on the front side, a rear display surface 14B on the rear side, a left display surface 14L on the left side, a right display surface 14R on the right side, and an upper display surface 14T on the upper side with respect to the moving direction D1. These display surfaces are collectively referred to as the display unit 14 (see FIG. 2). From the advantage of being able to simultaneously display content in multiple directions, it is preferable for the traveling display device 1 to have such five display surfaces, but it may also have 1 to 4 display surfaces.

[0012] The traveling display device 1 has a display function for displaying content such as facility guidance and advertisements, and a traveling function for traveling within the facility. The traveling display device 1 can display predetermined content on the display unit 14 while moving in the moving direction D1. The traveling display device 1 may be various traveling devices having a display unit capable of displaying content. Examples of the traveling display device 1 include, but are not limited to, digital signage devices.

[0013] At the upper end of the front surface of the traveling display device 1, a left imager 17L is disposed near the left end, and a right imager 17R is disposed near the right end. These imagers are collectively referred to as the imaging unit 17 (see FIG. 2). The left imager 17L and the right imager 17R image the periphery (front) of the traveling display device. Details of this imaging unit 17 will be described later with reference to FIG. 2.

[0014] As shown in FIG. 2, the traveling display device 1 includes a CPU 11, a storage unit 12, an operation unit 13, a display unit 14, a traveling device 15, a communication unit 16, and an imaging unit 17.

[0015] The CPU 11 controls each part of the traveling display device 1. The CPU 11 may be, for example, a processor or an MPU (Micro Processing Unit), but is not limited thereto. The CPU 11 includes a person information acquisition unit 11a and a destination determination unit 11b. For example, if programs corresponding to the person information acquisition unit 11a and the destination determination unit 11b that operate on this CPU 11 are stored in the storage unit 12, the person information acquisition unit 11a and the destination determination unit 11b are realized by the CPU 11 executing those programs. The person information acquisition unit 11a and the destination determination unit 11b may be configured by an electronic circuit, a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), etc., but are not limited thereto.

[0016] The person information acquisition unit 11a detects a person around the traveling device 15 and acquires the position information Ip of the person. The person information acquisition unit 11a detects a person by analyzing the surrounding video or image captured by the left imager 17L and the right imager 17R. Furthermore, it is also possible to acquire the position information of the detected person based on the principle of a stereo camera.

[0017] The destination determination unit 11b determines the destination Pd of the traveling device 15 based on the position information Ip of the person. The destination determination unit 11b will be described later with reference to FIG. 3 and subsequent figures.

[0018] The storage unit 12 stores information and data necessary for controlling each part of the traveling display device 1. The storage unit 12 may store or hold the OS, programs, etc. executed by the CPU 11. The storage unit 12 includes a memory, specifically, a volatile memory and a non-volatile memory. The volatile memory includes, for example, but is not limited to, DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory). The non-volatile memory includes, for example, but is not limited to, ROM (Read-Only Member), flash memory, SSD (Solid State Drive), and hard disk.

[0019] The operation unit 13 is an operation button, mouse, keyboard, touch panel, etc. that receives a user's operation. For example, the operation unit 13 receives the operation of the administrator of the traveling display device 1. For example, the administrator performs an operation of setting a traveling route, registering content, etc.

[0020] The display unit 14 is provided in the traveling device 15 and displays content. The display unit 14 is a liquid crystal display or an organic EL (Organic Electro-Luminescence) display that displays various types of information. Specifically, as shown in FIG. 1, the display unit 14 is provided on the left side surface of the device main body, and includes a left display surface 14L that displays information in the left direction with respect to the moving direction D1 (forward direction, front direction), a right display surface 14R that is provided on the right side surface of the device main body and displays information in the right direction with respect to the moving direction D1, a front display surface 14F that is provided on the front surface of the device main body and displays information in the forward direction with respect to the moving direction D1, a rear display surface 14B that is provided on the rear surface of the device main body and displays information in the rear direction with respect to the moving direction D1, and an upper display surface 14T that is provided on the upper surface (top surface) of the device main body and displays information in the upward direction with respect to the moving direction D1.

[0021] The operation unit 13 and the display unit 14 may be configured by an integrated touch panel.

[0022] The traveling device 15 includes drive wheels, a motor, a battery, etc. The traveling device 15 drives the motor with the power of the battery, and rotates the drive wheels with the driving force of the motor to make the traveling display device 1 travel. The battery is a rechargeable battery and is charged by an automatic charger (not shown). For example, the traveling display device 1 can charge the battery by the automatic charger at a predetermined charging position while traveling on a set traveling route.

[0023] Therefore, the traveling display device 1 detects surrounding people to acquire position information, determines a destination based on the position information, and displays content during or after movement. As a result, attention can be drawn to the content.

[0024] The communication unit 16 is a communication interface for wirelessly connecting the traveling display device 1 to a communication network and performing data communication according to a predetermined communication protocol with external devices such as a server via the communication network.

[0025] As described above, the imaging unit 17 has a left imager 17L and a right imager 17R. The left imager 17L and the right imager 17R may be visible light cameras, infrared cameras, or a combination thereof. For example, a distance image sensor using TOF (Time Of Flight) technology may be combined. However, the configuration of the imaging unit 17 is not limited to such examples.

[0026] (2) Basic Operations of the Traveling Display Device 1 Next, with reference to FIGS. 3 to 6, the basic operations of the traveling display device 1 will be described. FIG. 3 is an explanatory diagram showing the operation of the traveling display device 1 detecting a standing person H2 among surrounding people H1 to H4. FIG. 4 is an explanatory diagram showing the operation of the traveling display device 1 detecting the face direction Df of the person H2. FIG. 5 is an explanatory diagram showing the operation of the traveling display device 1 moving in front of the person H2. FIG. 6 is an explanatory diagram showing the positional relationship between the detected position Ph of the person, the current position Pc of the traveling display device 1, and the destination Pd.

[0027] The person information acquisition unit 11a further acquires the face orientation information If (corresponding to the face orientation Df) of the person, and the destination determination unit 11b may determine the destination Pd based on the position information Ip (corresponding to the position Ph) and the face orientation information If of the person. Therefore, since the traveling display device 1 detects not only the position Ph of the surrounding persons but also the face orientation Df, the moving direction of the person can be predicted with high accuracy. As a result, it can travel to a destination where there is a high possibility that the content can be recognized, and it is possible to more strongly arouse attention to the content.

[0028] For example, as shown in FIG. 3, when persons H1 to H4 are detected by analyzing the video captured by the imaging unit 17, the person information acquisition unit 11a focuses on the standing person H2. Next, as shown in FIG. 4, the person information acquisition unit 11a acquires the face orientation information If of the focused person H2. As shown in FIG. 6, it is predicted that the person H2 will move from the current position Ph in the direction of the face orientation Df. The destination determination unit 11b preferably determines a destination Pd suitable for attracting attention to the content based on such a prediction. Thereby, as shown in FIG. 5, the traveling display device 1 moves from the current position Pc to the destination Pd.

[0029] This destination Pd needs to approach ahead of the place where the person H2 is predicted to move, but it is better to deviate slightly to the side (either left or right) avoiding the direct front so as not to cause discomfort or the like. From such a viewpoint, the destination determination unit 11b determines the destination Pd based on the position Ph and the face orientation information If of the person H2. Note that the target on which the person information acquisition unit 11a focuses does not necessarily have to be a standing person, and may be, for example, a person walking slowly or a person showing other behaviors.

[0030] (3) Other operation examples of the traveling display device 1 Next, with reference to FIGS. 7 to 9, other operation examples of the traveling display device 1 will be described. FIG. 7 is an explanatory diagram showing the operation of the traveling display device 1 when a person highly likely to be searching for something is detected. FIG. 8 is an explanatory diagram showing other operation 1 of the traveling display device 1. FIG. 9 is an explanatory diagram showing other operation 2 of the traveling display device 1. FIG. 10 is an explanatory diagram showing other operation 3 of the traveling display device 1. FIG. 11 is an explanatory diagram showing other operation 4 of the traveling display device 1.

[0031] The person information acquisition unit 11a may identify a person whose face orientation Df has changed by a predetermined amount or more within a predetermined time, and the movement destination determination unit 11b may determine the movement destination Pd based on the position information Ip and the face orientation information If of the person identified by the person information acquisition unit 11a. Therefore, when there is a possibility that the person is looking for something, it can approach and display appropriate content such as facility guidance. As a result, necessary content can be provided in a timely manner.

[0032] For example, as shown in FIG. 7, if there is a person whose face orientation Df has changed by a predetermined amount or more within a predetermined time, it is preferable for the movement destination determination unit 11b to determine a movement destination Pd suitable for providing content such as facility guidance to the person. As this movement destination Pd, for example, it is better to be close to the position Ph of the person but shifted slightly to the side (either left or right) avoiding the direct front.

[0033] The movement destination determination unit 11b may determine, based on the position information Ip and the face orientation information If of the person, a position included within a range of a first angle a1 or less with respect to the direction in which the person's face faces as the movement destination Pd (other operation 1). Therefore, the traveling display device 1 moves in the direction in which the person will move or in a direction close thereto. As a result, attention can be drawn to the content to be displayed.

[0034] For example, as shown in FIG. 8, with the current position Ph of the person as a reference, the movement destination Pd is determined within the range of the first angle a1 on each of the left and right sides centered on the direction of the face orientation Df.

[0035] The destination determination unit 11b may determine, based on the position information Ip and the face orientation information If of the person, a position within a range of a first angle a1 or more and a second angle a2 or less with respect to the direction in which the person's face faces as the destination Pd (other operation 2). Accordingly, the traveling display device 1 moves in the direction in which the person will move, but can avoid the direct front of the moving direction. As a result, it is possible to attract attention to the content to be displayed without giving the person discomfort as much as possible.

[0036] For example, as shown in FIG. 9, with reference to the current position Ph of the person and centered on the direction Df of the face, the destination Pd is determined within a range of a first angle a1 or more and a second angle a2 or less on each of the left and right sides.

[0037] The person information acquisition unit 11a may further acquire movement state information that determines whether the movement state of the person is in motion or stopped. In this case, the destination determination unit 11b determines the destination Pd based on the position information Ip of the person and the movement state information. Accordingly, if the person is in motion, the moving destination of the person can be predicted and approached, and if the person is stopped, the current position Ph of the person can be approached. As a result, regardless of whether the person is in motion or stopped, it is possible to appropriately approach the person and attract attention to the content to be displayed.

[0038] When the movement state information of the person is stopped, the destination determination unit 11b may stop the traveling device 15 at a position included in a range of a first distance d1 or less from the position Ph of the person (other operation 3). Accordingly, the traveling display device 1 can approach the current position Ph of the person. As a result, it is possible to attract attention to the content to be displayed.

[0039] For example, as shown in FIG. 10, the destination Pd is determined within a range of a first distance d1 or less from the current position Ph of the person.

[0040] When the movement state information of the person is in a stopped state, the movement destination determination unit 11b may stop the traveling device 15 at a position included in a range from a first distance d1 or more to a second distance d2 or less from the position Ph of the person (other operation 4). Therefore, the traveling display device 1 approaches the current position Ph of the person but does not approach too closely. As a result, it is possible to attract attention to the content to be displayed without giving the person discomfort as much as possible.

[0041] For example, as shown in FIG. 11, a movement destination Pd is determined within a range from a first distance d1 or more to a second distance d2 or less from the current position Ph of the person.

[0042] When the movement state information of the person is in a moving state, the movement destination determination unit 11b may cause the traveling device 15 to travel alongside the person. Therefore, even when the person is moving, an appropriate positional relationship can be maintained continuously. As a result, it is possible to attract attention to the content to be displayed even for a moving person.

[0043] (4) Other embodiments The content may include not only visual data but also auditory data. In that case, the traveling display device 1 further includes an audio output unit that outputs auditory data. Examples of this audio output unit include, but are not limited to, a speaker, a buzzer, a chime, and a bell.

[0044] When the display unit 14 does not have display surfaces on all four sides of the traveling display device 1, the traveling device 15 may include a rotation drive unit that changes the horizontal direction. Thereby, the direction can be changed so that the content is easier to see from a specific person. As a result, even if the number of display surfaces arranged on the side surface of the traveling display device 1 is small, the content is easier to visually recognize.

[0045] Further, in order to widely monitor the surroundings of the traveling display device 1, an imaging unit different from the imaging unit 17 provided in the traveling display device 1 itself may be arranged at a high place to image so as to overlook the traveling display device 1 and its surroundings. Then, for example, the video images captured by the imaging units 17 of the plurality of traveling display devices 1 and the video images captured by the imaging unit arranged at a high place are analyzed by a server or the like wirelessly connected to these, and the moving destination Pd of each traveling display device 1 may be determined by this server or the like. Thereby, even when a plurality of traveling display devices 1 are arranged in a wide area, it is also possible to perform optimal content display by each traveling display device 1.

[0046] The present invention can be implemented in various other forms without departing from the gist or main features thereof. Therefore, the above-described embodiments are merely illustrative in all respects and should not be construed in a limiting sense. The scope of the present invention is indicated by the scope of the claims and is not restricted by the text of the specification. Further, modifications and changes belonging to the equivalent scope of the claims are all within the scope of the present invention.
