Are being installed.

However, the guide apparatuses installed in the conventional transportation apparatus mainly guide information through visual or auditory stimuli, and it was difficult to efficiently transmit information in the driving environment of the transportation apparatus in which noise is frequently generated (audible hearing). ), It could interfere with the driver's forward attention (visual).

Therefore, in recent years, guide devices for guiding the state information of the transportation device using the 'tactile' have been developed, and these guide devices provide various information to the driver or the passenger by using the vibration stimulus generated by the vibration device. However, the guidance method by vibrating stimulation also has a problem that a vibration for providing a tactile feeling may affect the operation of an operating device (such as a steering wheel), and a safety accident may occur. In addition, when the transport device vibrates due to external factors, there is a problem in that the driver or passenger cannot fully recognize the 'guidance by the vibration stimulus' due to external vibration, and there is a problem that the transmitted information may be misrecognized. .

Therefore, the development of a new concept of guidance device that can solve these problems is required.

The present invention has been invented on the basis of this technical background, in order to meet the salping technical needs from above, as well as to provide additional technical elements that can be easily invented by those skilled in the art.

The present invention can generate a 'touch' for guiding the state information of the transport apparatus by using the 'laser beam'. Therefore, it is possible to provide a tactile sense without affecting the operation of the internal components of the transport apparatus (for example, a steering wheel on which the tactile generating unit is installed). (In the past, tactile sensations were implemented, for example, when the tactile generator is installed on the steering wheel, the steering wheel itself vibrates in the process of providing tactile feeling, which may affect driving conditions.)

The embodiments are provided so that those skilled in the art can easily understand the technical spirit of the present invention, and thus the present invention is not limited thereto. In addition, the matters described in the attached drawings may be different from those actually implemented by the schematic drawings to easily describe the embodiments of the present invention.

In addition, each component expressed below is only an example for implementing this invention. Thus, in other implementations of the present invention, other components may be used without departing from the spirit and scope of the present invention. In addition, each component may be implemented solely by hardware or software configuration, but may be implemented by a combination of various hardware and software configurations performing the same function.

In addition, the expression "comprising" certain components merely refers to the presence of the components as an 'open' expression, and should not be understood as excluding additional components.

Hereinafter, referring to FIG. 1 to FIG. 8, a 'guide device 100 for guiding state information of a transport device' according to an embodiment of the present invention will be described.

Referring to FIG. 1, the guide apparatus 100 according to an embodiment of the present invention may include a tactile generator 110 generating a pulse laser beam to generate a tactile sense, and a transport apparatus ( The controller 150 may control an operation of the tactile generator based on state information of the vehicle.

In addition, the guide apparatus 100 may further include a communication unit 130 for transmitting and receiving data. In this case, the communication unit 130 may be controlled by the control unit 150.

In addition, the guide apparatus 100 may be installed in various internal components of the transport apparatus. For example, the guide apparatus 100 may be installed in various internal components such as an operation unit (operation handle), a transmission unit (gear transmission), a seat, and the like of the transportation device.

The vehicle (Vehicle), as described above, means a variety of power devices used for the transport of people or things. Such a transportation device may include various power devices such as airplanes, automobiles, motorcycles, trucks, buses, trains, spacecrafts, etc., and may include not only existing transportation devices but also various transportation devices to be developed in the future.

The tactile generation unit 110 is configured to generate a tactile for guiding the state information of the transportation device. The tactile generator 110 may generate and output a laser beam as illustrated in FIG. 2, and may generate a tactile sense using the laser beam.

In addition, the tactile generator 110 may include a laser generation module 112 for generating a laser beam, an optical filter module 114 for adjusting the power of the laser beam, and a diameter of the laser beam. It may include a lens module 116 to adjust, in addition to these configurations may include a variety of configurations for generating and adjusting the laser beam.

On the other hand, when the laser generation module 112 is a semiconductor laser diode, the optical filter module 114 may be excluded from the configuration.

Here, the laser generation module 112 may include a laser driver, a cooling device, and the like, for generating and outputting a laser beam. The laser driver is configured to include a laser medium, an optical pumping unit, an optical resonator, and the like, and generates an optical signal constituting the pulsed laser beam. In addition, the cooling device is configured to remove heat that may be generated in the process of generating an optical signal by the laser driver, and serves to protect the laser driver device.

The laser generation module 112 may be formed in various forms capable of generating a laser beam. For example, the laser output unit 110 may be a ruby laser, neodymium: yag laser (Nd: YAG laser), neodymium: glass laser (Nd: glass laser), laser diode (Ga, Al, As), excimer ( Excimer) can be formed in the form of a laser, a dye laser, and the like, in addition to this kind can be configured in various forms, such as a semiconductor laser diode.

In addition, the laser generation module 112 preferably generates a pulse laser beam using a pulse laser rather than a continuous laser (CW laser, continuous wave laser). When the laser stimulation is continuously provided, the photo-chemical effect or the photo-thermal effect may occur and cause adverse effects on the human body. Therefore, a pulsed laser beam is used to obtain a photo-mechanical touch with these effects minimized. .

In addition, the laser generation module 112 may adjust energy per unit pulse of the pulsed laser beam, and may generate an opto-mechanical touch through the adjustment operation of such a parameter. When the exposure time and the energy per unit pulse are adjusted to a specific range, a phenomenon such as a plasma shock wave may occur by the pulse laser beam, because the photo-mechanical touch may be generated based on the phenomenon. On the other hand, the adjustment of the energy per unit pulse is achieved through the operation of adjusting the intensity (Power, J / s) of the optical signal constituting the pulse laser beam, or adjust the pulse width of the pulse laser beam This can be achieved through the operation. (For reference, referring to FIG. 3, the optical signal intensity (Power, J / s), pulse width, pulse repetition rate, etc.) of the pulse laser beam may be checked. 'Adjusting' the energy per unit pulse by the generating module 112 may mean that the laser generating module 112 changes the energy per unit pulse, but the laser generating module 112 It may also mean to maintain the energy per unit pulse at a specific value (constant value). That is, the operation of 'adjusting' the energy per unit pulse includes not only the operation of changing the energy per unit pulse, but also an operation of maintaining the energy per unit pulse at a specific value (constant value) or a specific range of values. Can be.

In addition, the laser generation module 112 may adjust the energy per unit pulse in a pulse width condition of several tens of ms (millisecond) or less. Even in the case of using a pulsed laser beam, when the pulse width is large, sufficient exposure time of the laser stimulus is ensured, and thus a photo-chemical effect or a photo-thermal effect may occur. Therefore, it is desirable to minimize this phenomenon by controlling the energy per unit pulse in a pulse width condition of several tens of ms (millisecond) or less.

In addition, the laser generation module 112, it is preferable to adjust the energy per unit pulse to a value of 0.005 mJ or more. As will be seen later, under these conditions, it may cause photo-mechanical touch to the skin tissue of the human body, and even non-human objects may cause photo-mechanical stimulation according to the intensity of energy per unit pulse.

On the other hand, the laser generation module 112 serves to provide 'touch directly to the skin tissue', or 'indirectly provide a touch by generating a mechanical stimulus with the clothing sandwiched between'. Can be done. 1) First, in the former case, the laser generating module 112 is installed in a steering wheel operating device, a gear operating device, or the like directly facing the skin. In this case, the laser generating module 112 is provided per unit pulse. It is desirable to adjust the energy to a value of 9.5 mJ or less. As will be seen later, the photomechanical level of the photomechanical tactile sensation may be large enough to damage the human skin tissue. Therefore, in order to secure safety in providing a photo-mechanical touch directly to the human body, it is preferable to adjust the energy per unit pulse to a value of 9.5 mJ or less. 2) In the latter case, the laser generating module 112 is installed in a seat or the like that does not directly face the skin. In this case, the energy per unit pulse is preferably controlled to a value of 9.5 mJ or more. Do. Since the stimulus may be attenuated by the garment or the like existing between the laser generating module 112 and the skin, it is necessary to implement a photo-mechanical stimulation of sufficient intensity.

The optical filter module 114 is a configuration for adjusting the intensity (Power, J / s) of the optical signal constituting the pulsed laser beam, the laser output from the laser generation module 112 through this intensity adjustment The energy can be adjusted secondly per unit pulse of the beam.

The optical filter module 114 may include an attenuator device that attenuates the intensity of the optical signal. The optical filter module 114 may attenuate the intensity (Power, J / s) of the optical signal using the apparatus. Therefore, the optical filter module 114 may perform an operation of reducing energy per unit pulse by attenuating the intensity of the optical signal in the same pulse width.

On the other hand, the optical filter module 114, if the laser generation module 112 itself has the ability to adjust the energy per unit pulse may be selectively mounted on the tactile generating unit 110, the unit It can play a secondary role to fine tune the energy per pulse. However, when the laser generation module 112 itself does not have the ability to adjust the energy per unit pulse, it is essentially mounted on the tactile generating unit 110 to play a leading role in controlling the energy per unit pulse. Will perform.

The lens module 116 is configured to adjust a diameter of the pulsed laser beam. The lens module 116 includes a light focusing unit (for example, a convex lens unit) for focusing the pulsed laser beam and a light diffusing unit (eg, concave lens unit, etc.) for diffusing the pulsed laser beam. The diameter of the pulsed laser beam may be increased or decreased through selective operation of the light converging unit and the light diffusing unit.

As described above, the tactile generation unit 110 may be installed in various internal components including an operation unit (operation handle), a transmission unit (gear transmission), a seat, and the like, of FIGS. 4 to 6. By using the laser generating module 112, the optical filter module 114, the lens module 116, and the like, the driver or the passenger may be provided with the touch caused by the photo-mechanical stimulus.

The communication unit 130 is a configuration for transmitting and receiving information with various devices or external devices installed in the transportation device. The communication unit 130 may be configured in the form of various wired communication devices or wireless communication devices satisfying standards such as IEEE, ISO, IEC, ITU, etc., and may be implemented as various types of communication devices in addition to these standards. have.

The controller 150 is a component for controlling various components of the guide apparatus 100 including the tactile generating unit 110 and the communication unit 130.

The controller 150 may include at least one arithmetic means and a storage means, wherein the arithmetic means may be a general purpose CPU (CPU), but may be implemented as a programmable device element suitable for a specific purpose. CPLD, FPGA) or application specific semiconductor processing unit (ASIC) or microcontroller chip. Also, the storage means may be a volatile memory element, a non-volatile memory or a non-volatile electromagnetic storage element, or a memory within the computing means.

In addition, the controller 150 may manage various state information of the transport apparatus, and may control the operation of the tactile generating unit 110 based on the state information. In detail, the controller 150 may manage various state information such as driving state information, dangerous state information, internal part state information, direction information, emergency occurrence information, execution state of a specific function, and the like of the transport device. The operation of the tactile generator 110 may be controlled based on state information. On the other hand, the controller 150 is connected to a variety of equipment such as a sensor (Sensor), an electronic control unit (ECU) installed in the transport device wired or wirelessly collects the state information, or equipment installed outside the transport device It can also be connected wirelessly to collect status information.

In addition, the control unit 150 may control the operation of the tactile generating unit 110 in a state of interlocking with the navigation (ground, marine, aviation, etc.) installed in the transportation device. In detail, the controller 150 may include navigation-related information (travel direction information, route surrounding information, etc.), which is conventionally provided in the form of visual stimulus or auditory stimulus, in the form of tactile stimulus through the tactile generator 110. Can provide. Therefore, even if the driver or the passenger does not directly look at the navigation screen, navigation-related information may be provided, and navigation-related information may be efficiently provided even in a noise environment in which an auditory stimulus cannot be properly transmitted.

In addition, the controller 150 controls the operations of the laser generation module 112 and the optical filter module 114 included in the tactile generation unit 110 to collectively control the energy per unit pulse of the pulsed laser beam. Can be adjusted. Specifically, the controller 150 controls the operations of the laser generation module 112 and the optical filter module 114 to adjust the pulse width and the intensity (Power, J / s) of the optical signal. The energy per unit pulse may be adjusted by adjusting the parameters.

In addition, the controller 150 may control the operation of the lens module 116 included in the tactile generator 110 to adjust additional parameters of the pulsed laser beam. Specifically, the controller 150 may additionally adjust the diameter of the pulsed laser beam through the operation of the lens module 116.

In addition, the controller 150 may operate in a control mode for increasing the photo-mechanical touch or in a control mode for reducing the photo-mechanical touch. 1) First, when the control unit 150 operates in a control mode for increasing the photo-mechanical touch, the control unit 150 performs a control operation for sequentially increasing the energy per unit pulse, and the pulse laser beam is induced through this operation. Can increase the photo-mechanical touch. 2) In addition, the control unit 150, when operating in a control mode for reducing the photo-mechanical tactile, performs a control operation to sequentially reduce the energy per pulse, through which the pulse laser beam is induced It can reduce the photo-mechanical touch.

On the other hand, the salping guide device 100 according to an embodiment of the present invention, may be configured in the form including a plurality of the tactile generating unit 110. In detail, the guide apparatus 100 may be configured to include a plurality of tactile generators 110 as shown in FIGS. 4 to 6.

In this case, the controller 150 may individually or integrally control the plurality of tactile generators 110, and may implement various tactile patterns through such control.

In particular, the controller 150 may implement two or more tactile patterns (tactile pattern 1, tactile pattern 2, etc.) by selectively operating the plurality of tactile generating units 110 as shown in FIG. The control operation may be performed in a state in which the patterns are matched with two or more pieces of state information (for example, the tactile pattern 1-the gear is set to the P mode / the tactile pattern 2-the gear is set to the D mode, etc.). Accordingly, the controller 150 may provide various state information through this control operation.

In addition, the controller 150 may operate a plurality of tactile generating units 110 at a time difference as shown in FIG. 8 to implement various tactile patterns (tactile pattern A, tactile pattern B, etc.), and through the tactile patterns Direction information can be provided. For example, the controller 150 sequentially drives the tactile generators 110 in the right direction as shown in the left side of FIG. 8 to implement a 'tactile movement in the right direction', or the right side of FIG. 8. As described above, the tactile generator 110 may be sequentially driven in an upward direction to implement a 'tactile movement in an upward direction'. Accordingly, the controller 150 may guide various direction information based on the operation. For example, based on the direction information providing function, the controller 150 performs a direction information guiding operation such as a state guide in which an object approaches the right direction and a state guide (navigation related information) to turn left at the next intersection. Can be done.

Meanwhile, the controller 150 may control the plurality of tactile generators 110 in various ways in addition to the embodiment of FIGS. 7 and 8 described above, and forms various types of tactile patterns through such control. can do. Accordingly, by matching these various tactile patterns with various state information, it is possible to efficiently provide the state information of the transportation device to the driver or the occupant.

Experimental Example 1

Hereinafter, with reference to FIGS. 9 to 13, experimentally verify that the 'photo-mechanical tactile' is caused by the 'pulse laser beam' generated by the tactile generator 110 according to an embodiment of the present invention. .

9 is a diagram illustrating a configuration of an experimental system for confirming the photo-mechanical effect of the laser beam generated by the tactile generator 110.

Such an experimental system may include a configuration of a tactile generation unit 110, a collagen film, a piezo sensor, a three-axis position fine adjustment device, a computer, and the like that generate a pulse laser beam.

The tactile generator 110 is a component included in the guide apparatus 100 according to the present invention as described above, and generates and outputs a pulsed laser beam.

In this experiment, as an example of the pulsed laser beam generated by the tactile generator 110, a wavelength of 532 nm, a pulse width of 5 ns, a pulse repetition rate of 10 Hz, A pulsed laser beam with a beam diameter of 0.48 mm (diameter irradiated to the collagen film) was used.

The collagen film is a type I collagen film (Neskin®-F, Medira, thickness of 300 μm to 500 μm) used for clinical treatment epidermal healing & substitue, modeling human skin tissue. Configuration. Since more than 90% of the living tissue is composed of type I collagen, the collagen film can be used to indirectly experiment with the effects that will occur in living skin tissue.

However, since the skin thickness (epidermis) of the human body differs according to individual, sex, and race, in this experiment, five collagen films were first conducted, and secondly, collagen films were used. The experiment was conducted. This is because the skin thickness of the human body may vary in the range of 5 to 10 collagen films according to individual, sex, and race. Referring to Table 1, the weight and thickness of five collagen films and ten collagen films can be confirmed.

Number of collagen films Weight [g] Thickness [mm] Chapter 5 0.12 0.15 Chapter ten 0.23 0.31

On the other hand, the collagen film was used in the form attached to the piezo sensor.

The piezo sensor is an element expressing a mechanical stimulus applied from the outside as an electrical output signal. Therefore, in this experiment, the piezoelectric sensor was used to observe the mechanical change caused in the collagen film.

On the other hand, in this experiment, a surface-coated piezo sensor (LFT1-028K, Measurement specialties) was used, in order to minimize the effect that the sensor surface can be applied when the collagen film is attached.

The three-axis position fine adjustment device is a device for finely controlling the position of the piezo sensor. The computer is a device for receiving a signal output from the piezo sensor, analyzing the received signal, and displaying the analyzed result.

In the above, the following experiment was conducted using a salping test system.

1) An experiment was performed in which a collagen film composed of five sheets was irradiated with a pulse laser beam having an energy of 0.05 mJ per unit pulse.

2) The pulsed laser beam was irradiated at a frequency of 10 Hz. Specifically, the pulsed laser beam was irradiated immediately before 0.05 [s], immediately before 0.15 [s], immediately before 0.25 [s], and immediately before 0.35 [s].

3) The signal of the piezo sensor output during the experiment was analyzed.

10 is a graph showing the results of this experiment. Referring to FIG. 10, it can be seen that the output signal of the piezo sensor is generated at a frequency of 10 Hz corresponding to the pulse repetition rate of the irradiated laser beam. In addition, it is confirmed that the time when the output signal is generated by the piezo sensor coincides with the time when the pulse laser beam is irradiated (just before 0.05 [s], just before 0.15 [s], just before 0.25 [s], 0.35 [s], etc.). Can be.

Therefore, through these experimental results, it can be seen that the pulsed laser beam caused the photo-mechanical touch. Also, by analyzing the magnitude of the output signal of the piezo sensor, the intensity (magnitude) of the induced photo-mechanical touch can also be calculated.

In addition, the following experiment was also carried out using the salping test system.

1) First, while irradiating a pulsed laser beam to the collagen film consisting of five sheets using the tactile generation unit 110, the output signal of the piezo sensor was observed. In particular, the experiment was performed while sequentially changing the energy per unit pulse of the pulse laser beam irradiated by the tactile generation unit.

2) Next, while irradiating the pulse laser to the collagen film consisting of 10 sheets using the tactile generation unit 110, the output signal of the piezo sensor was observed. In this case as well, the experiment was performed while sequentially changing the energy per unit pulse of the pulsed laser beam irradiated by the tactile generator 110.

On the other hand, in this experiment, the experiment was conducted with a pulse width of 5 ns that satisfies the range of ms (millisecond) or less. Changed.

In addition, the signal output from the piezo sensor was analyzed through a process such as i) preprocessing filtering, ii) removing low frequency components, and iii) detecting a maximum value, as shown in FIG. In other words, the output signal of the piezo sensor was analyzed through a process of preliminarily filtering to remove noise, secondly removing low frequency components, and detecting a maximum value of the signal. In addition, the results were expressed using the average value of the detected maximum values.

12 and 13 are graphs showing the results of this experiment.

12 is a graph illustrating a change in an output signal of a piezo sensor according to a change in energy per unit pulse. Here, the horizontal axis is analyzed by setting the energy per unit pulse, and the vertical axis is analyzed by setting the output signal of the piezo sensor divided by the unit thickness (sensor output signal per unit thickness).

13 is an enlarged graph of a partial region of the graph of FIG. 12. Specifically, FIG. 12 is an enlarged graph of an area surrounded by a dotted line.

12 and 13, 1) for the collagen film consisting of 5 sheets, it can be seen that the photo-mechanical touch is induced when energy per unit pulse of 0.00398 mJ or more is applied, and 2) 10 sheets For the collagen film, it can be seen that the photo-mechanical touch is caused when energy per unit pulse of 0.005 mJ or more is applied. Therefore, it can be seen that the threshold energy for inducing photo-mechanical touch of the collagen film composed within the range of 5 to 10 is in the range of 0.00398 mJ to 0.005 mJ.

On the other hand, as described above, the skin thickness of ordinary people is in the range of 5 to 10 collagen film. Thus, applying a pulsed laser beam having an energy per unit pulse of at least 0.005 mJ or more to the human body can cause an opto-mechanical touch regardless of the difference in individual skin thickness.

12 and 13, it can be seen that the upper limit for increasing the energy per unit pulse is set to about 9.5 mJ. This is because the collagen film is damaged in the experiment in which the energy per unit pulse is set to 9.5 mJ or more. Therefore, in order to ensure safety when irradiated to the human skin, the energy per unit pulse is preferably limited to the range of 9.5 mJ or less.

Meanwhile, referring to FIGS. 12 and 13, when the energy per unit pulse is increased or decreased in the range of 0.005 mJ to 9.5 mJ, the output signal of the piezo sensor may also be increased or decreased together. That is, it can be seen that as the energy per unit pulse increases in the corresponding range, the photo-mechanical touch increases, and as the energy per unit pulse decreases, the photo-mechanical touch decreases.

Thus, by increasing or decreasing the energy per unit pulse, it is possible to perform a control operation to increase or decrease the photo-mechanical tactile feeling.

On the other hand, the salping experiment above, by irradiating the laser beam 'directly to the skin' caused a mechanical sensation (mechanical stimulation), in this state, a parameter control method that can provide a mechanical sensation (mechanical stimulation) safely to the skin Presented.

However, as described above, the guide apparatus 100 according to an embodiment of the present invention may be configured in a form that provides a mechanical touch (mechanical stimulus) to a body part coated with clothing, in which case it is directly directed to the skin. If the parameter is controlled as in the case of irradiating a laser beam, only a very small mechanical stimulus of a size that is difficult for a human to perceive due to the stimulus attenuation effect by clothing can be transmitted. Therefore, in such an embodiment, it is preferable to control the energy per unit pulse by a large value over the control range (0.005 to 9.5 mJ) of the energy per unit pulse presented in the above experiment.

Experimental Example 2

Hereinafter, referring to FIGS. 14 to 16, experimentally verify that the 'optical-mechanical tactile' is caused by the 'pulse laser beam' generated by the tactile generator 110 according to the exemplary embodiment of the present invention. .

In order to verify that the 'optical-mechanical touch' is induced by the 'pulse laser beam', the following experiment was conducted.

1) First, the EEG (Electro Encephalo Graphy) device was observed using the EEG (Electro Encephalo Graphy) while irradiating the pulse laser beam generated by the tactile generation unit to the right hand. (FIG. 14A-Experimental Group)

2) EEG was also observed using the EEG device while mechanically applying the stimulus to the right hand using a rod. (FIG. 14B-Control)

In the experiment, a pulse laser beam having a wavelength of 532 nm, a pulse width of 5 ns, an energy per unit pulse of 1.9 mJ, and a beam diameter of 0.48 mm was used. Mechanical stimulation was applied using a rod having the same diameter as the beam. In addition, the observation of the EEG using the EEG device was made in the C3 region and the C4 region, which are the body sensory cortex regions of the whole region of the brain.

15 to 16 show the result data of this experiment.

As can be seen in Figures 15 to 16, the EEG response of the experimental group (observing the EEG response in the state of applying a pulse laser beam) and the control group (observing the EEG response in the state of applying a mechanical stimulation using a rod) the same EEG frequency Significant increases in the average magnitude of EEG in the area were observed. Although the EEG response was delayed for a predetermined time in the experiment with the 'pulse laser beam', the phenomenon itself that the body sensory cortical regions (C3, C4) are activated by the 'pulse laser beam' is clearly confirmed. Could be In addition, the shape of the EEG response graph when the 'pulse laser beam' is applied is also in the same frequency region of the EEG as in the case where the 'rod stimulation (pure mechanical stimulation)' is applied except for the region in which the response is delayed. It was confirmed that the average size of the EEG increases.

Therefore, through this experiment, it can be verified that the 'photo-mechanical tactile' is caused by the 'pulse laser beam'.
