[0175] Figure 4 , Figure 5 and Figure 6 is a diagram for generating hand signal information of a personal mobile device according to an embodiment of the present invention.

[0176] The personal mobile device 1 may generate first-hand signal information by identifying surrounding conditions.

[0177] The first hand signal information may include at least one of size information of the hand signal, left or right position information of the hand signal, transmission direction information of the hand signal, and transmission range information of the hand signal.

[0178] Hereinafter, a method for generating first hand signal information according to the distribution of a plurality of personal mobile devices 111 located within a predetermined range will be described.

[0179] Here, the distribution of the plurality of personal mobile devices 111 may mean the number of the plurality of personal mobile devices 111 located within a predetermined range and the detailed locations of the plurality of personal mobile devices 111 located within the predetermined range.

[0180] In more detail, the detailed locations of the personal mobile devices within the predetermined range may be the distances between the plurality of personal mobile devices 111 and the personal mobile device 1 .

[0181] The predetermined range may mean a range within a certain distance in front, rear, left, and right directions centered on the personal mobile device 1 , and the direction and distance may be set according to a user's selection.

[0182] For example, Figure 4 As shown, the personal mobile device 1 can identify five personal mobile devices among the plurality of personal mobile devices 111 around the personal mobile device 1 .

[0183] If the number of the plurality of personal mobile devices 111 identified as being located within the predetermined range is five, detailed locations of the plurality of personal mobile devices 111 may be determined. Each distance between the personal mobile device 1 and the determined plurality of personal mobile devices 111 may be detected.

[0184] If it is determined that the distance is narrower than a certain distance, the size information of the first hand signal may be determined as a small hand signal. Figure 6 As shown, the small hand signal may be the transmission of a hand signal using the user's hand.

[0185] When it is determined that the determined detailed positions of the plurality of personal mobile devices 111 are gathered in the d area based on the personal mobile device 1, the personal mobile device 1 may determine the position of the right hand signal. For example, when the hand signal position is right, the hand signal may be sent using the user's right wrist or right arm, such as Figure 6 shown.

[0186] The personal mobile device 1 selects any one of the plurality of personal mobile devices 111 for sending the first hand signal, and may determine the transmission range information of the first hand signal based on the detailed location of the selected personal mobile device 111. In more detail, Figure 5 As shown, the hand signal transmission range of the first hand signal information may be based on personal mobile devices within a predetermined range of the personal mobile device 1 .

[0187] The hand shape corresponding to the personal mobile device within the predetermined range may be set. For example, in order to send a hand signal to a personal mobile device within a distance of 7 m based on the personal mobile device 1, the set hand shape may be to use two fingers, but is not limited thereto.

[0188] For example, in order to send a hand signal to a personal mobility device or a pedestrian in front of the personal mobility device 1 , the set hand shape may be such that the palm is visible, but is not limited thereto.

[0189] For example, Figure 4 As shown, the personal mobile device 1 can identify three personal mobile devices among the plurality of personal mobile devices 111 around the personal mobile device 1 .

[0190] If the number of the plurality of personal mobile devices 111 identified as being located within the predetermined range is three, detailed locations of the plurality of personal mobile devices 111 may be determined. Each distance between the personal mobile device 1 and the determined plurality of personal mobile devices 111 may be detected.

[0191] If it is determined that the distance is wider than a certain distance, the size information of the first hand signal may be determined as a large hand signal. Figure 6 As shown, a large hand signal may be a transmission of a hand signal using the user's arm.

[0192] When it is determined that the determined detailed locations of the plurality of personal mobile devices 111 are clustered in the b-zone based on the personal mobile device 1 , the personal mobile device 1 may determine the transmission direction of the first hand signal as the rear b-zone.

[0193] For example, Figure 4 As shown, the personal mobile device 1 can identify multiple personal mobile devices 111 centered around the personal mobile device 1 .

[0194] If the number of personal mobile devices 111 identified as being within the predetermined range is one, the detailed location of the personal mobile device 111 may be determined. The distance between the personal mobile device 111 and the determined personal mobile device 111 may be detected.

[0195] If it is determined that the distance is wider than a certain distance, the size information of the first hand signal may be determined as a large hand signal. Figure 6 As shown, the large hand signal may be the transmission of a hand signal using the user's arm.

[0196] When it is determined that the determined detailed locations of the plurality of personal mobile devices 111 are concentrated in the d area based on the personal mobile device 1 , the personal mobile device 1 may determine the transmission direction of the first hand signal as the front d area.

[0197] Hereinafter, a method for generating first-hand signal information according to the distribution of a plurality of pedestrians located within a predetermined range will be described.

[0198] Here, the distribution of the plurality of pedestrians may mean the number of the plurality of pedestrians located within the predetermined range and the detailed positions of the plurality of pedestrians located within the predetermined range.

[0199] In more detail, the detailed positions of the plurality of pedestrians within the predetermined range may be the distances between the plurality of pedestrians and the personal mobility device 1 .

[0200] The predetermined range may mean a range within a certain distance in all directions of the front, rear, left, and right with the personal mobile device 1 as the center, and the direction and distance may be set according to a user's selection.

[0201] For example, Figure 4 As shown, the personal mobility device 1 can identify seven pedestrians around the personal mobility device 1 .

[0202] If the number of the plurality of pedestrians identified as being located within the predetermined range is seven, the detailed positions of the plurality of pedestrians may be determined. Each distance between the personal mobile device 1 and the determined plurality of pedestrians may be detected.

[0203] If it is determined that the distance is wider than a certain distance, the size information of the first hand signal may be determined as a large hand signal. Figure 6 As shown, the large hand signal may be the transmission of a hand signal using the user's arm.

[0204] When it is determined that the detailed positions of the plurality of pedestrians are concentrated in the c-zone based on the personal mobile device 1 , the personal mobile device 1 may determine the transmission direction of the first-hand signal as the front c-zone.

[0205] For example, Figure 4 As shown, the personal mobility device 1 can identify three pedestrians around the personal mobility device 1 .

[0206] If the number of the plurality of pedestrians identified as being located within the predetermined range is three, the detailed positions of the plurality of pedestrians may be determined. Each distance between the personal mobile device 1 and the determined plurality of pedestrians may be detected.

[0207] If it is determined that the distance is greater than a certain distance, the size information of the first hand signal may be determined as a large hand signal. Figure 6 As shown, the large hand signal may be the transmission of a hand signal using the user's arm.

[0208] When it is determined that the detailed positions of the plurality of pedestrians are gathered in the d area based on the personal mobile device 1, the personal mobile device 1 may determine the hand signal position to the right. For example, when the hand signal position is to the right, the hand signal may be sent using the user's right wrist or right arm, such as Figure 6 shown.

[0209] For example, Figure 4 As shown, the personal mobility device 1 can identify a pedestrian around the personal mobility device 1 .

[0210] If the number of pedestrians identified as being within the predetermined range is one, the detailed position of the pedestrian may be determined. The distance between the personal mobile device 1 and the determined pedestrian may be detected.

[0211] If it is determined that the distance is wider than a certain distance, the size information of the first hand signal may be determined as a large hand signal. Figure 6 As shown, the large hand signal may be sent as a hand signal using the user's arm.

[0212] Based on the personal mobility device 1 , when it is determined that the detailed positions of the multiple pedestrians are located between the d area and the c area, the personal mobility device 1 may determine the transmission direction of the first hand signal as the front d area and the right c area.

[0213] Fig. 7A and Figure 7B is a flowchart of a control method of a personal mobile device according to an embodiment of the present invention.

[0214] The method starts with a state where the personal mobility device 1 is traveling ( 710 ). This state can be determined by the personal mobility device 1 .

[0215] While the personal mobility device 1 is driving, the personal mobility device 1 may determine whether a user's gesture has occurred ( 711 ).

[0216] In more detail, the user's gesture may be a user's gesture detected by a wearable electronic device 2 connected to the personal mobile device 1 through wireless communication. When the wearable electronic device 2 detects the user's gesture, the wearable electronic device 2 may send information corresponding to the gesture to the personal mobile device 1. The personal mobile device 1 may determine whether the user's gesture has occurred by receiving the information corresponding to the gesture.

[0217] If it is determined that the user's gesture has occurred (Yes at 711 ), the personal mobile device 1 may determine whether the gesture is a meaningful hand signal ( 712 ).

[0218] In more detail, when determining whether the gesture is a meaningful hand signal, the personal mobile device 1 may determine whether the gesture matches a predetermined gesture, and if the gestures match, the gesture may be determined to be a meaningful gesture.

[0219] If it is determined that the user's gesture is meaningful (Yes at 712 ), the personal mobile device 1 may recognize the surrounding situation of the personal mobile device 1 ( 713 ).

[0220] Identifying the surrounding situation may be identifying at least one of the number of personal mobile devices within a predetermined range of the personal mobile device 1, the detailed locations of the personal mobile devices within the predetermined range, the number of pedestrians within the predetermined range, and the detailed locations of the pedestrians within the predetermined range.

[0221] Within the predetermined range, the direction and distance may be set according to the selection of the user of the personal mobility device 1 .

[0222] Recognizing surrounding conditions can be based on image information obtained by a camera. In addition, recognizing surrounding conditions can be based on location information of personal mobile devices located within a predetermined range and location information of pedestrians located within a predetermined range obtained by an intelligent transportation system (ITS).

[0223] The ITS device may be installed on a personal mobile device located within a predetermined range, detect a location value of the personal mobile device located within the predetermined range, and transmit the detected location value to the personal mobile device 1 .

[0224] In addition, the ITS device may be installed on a wearable electronic device of a pedestrian located within a predetermined range, detect a position value of the pedestrian located within the predetermined range, and send the detected position value of the pedestrian to the personal mobile device 1 .

[0225] The personal mobile device 1 may determine whether there is an object to which at least one hand signal is to be sent based on the surrounding situation, such as a personal mobile device, a pedestrian, or a vehicle ( 714 ).

[0226] If there is no object to which a hand signal is to be sent among the personal mobile device, pedestrians, and vehicles (No at 714 ), the personal mobile device 1 may repeatedly identify the surrounding situation of the personal mobile device 1 ( 715 ).

[0227] If it is determined that there is an object to which a hand signal is to be sent (Yes at 714 ), the personal mobile device 1 may check whether the position or direction of the object to which a hand signal is to be sent can be determined ( 720 ).

[0228] If the position or direction of the object to which the hand signal is to be sent cannot be determined (No at 720 ), it is determined that the position of the object to which the hand signal is to be sent is incorrect, so that the identification of the surrounding situation of the personal mobile device 1 may be repeated ( 715 ).

[0229] If the position or direction of the object to which the hand signal is to be sent can be determined (Yes at 720 ), the personal mobile device 1 can determine the detailed position of the object to which the hand signal is to be sent.

[0230] The personal mobile device 1 may check whether the object to which the hand signal is to be sent is located on the right or left ( 721 ).

[0231] The personal mobile device 1 may generate left or right position information of the hand signal based on the position of the object to which the hand signal is to be sent. For example, when the position information of the hand signal is the left side, the user may generate information for suggesting the use of "left wrist or left arm".

[0232] The personal mobile device 1 may check whether the object to which the hand signal is to be sent is located in front or behind ( 722 ).

[0233] The personal mobile device 1 may generate the hand signal transmission direction information based on the position of the object to which the hand signal is to be sent.

[0234] The personal mobile device 1 may determine whether the distance between the object to which the hand signal is to be sent and the personal mobile device 1 is close ( 723 ).

[0235] If the distance between the object to which the hand signal is to be sent and the personal mobile device 1 is not close (No at 723), the personal mobile device 1 may generate first hand signal information including hand signal size information for suggesting the user to use a "large hand signal" (724).

[0236] If the distance between the object to which the hand signal is to be sent and the personal mobile device 1 is close (yes at 723), the personal mobile device 1 may generate first hand signal information including hand signal size information for suggesting the user to use a “small hand signal” (725).

[0237] For example, a small hand signal may send a hand signal using a user's wrist, and a large hand signal may send a hand signal using a user's arm.

[0238] The personal mobile device 1 can generate the first hand signal information by including at least one of the size information of the hand signal based on the position of the object to which the hand signal is to be sent, the left or right position information of the hand signal, the transmission direction information of the hand signal, and the transmission range information of the hand signal.

[0239] The user who has boarded the personal mobility device 1 may perform a first hand signal corresponding to the first hand signal information.

[0240] The personal mobile device 1 may determine whether there are more objects around the personal mobile device 1 to which a hand signal is to be sent ( 730 ).

[0241] If there is another object to which a hand signal is to be sent around the personal mobile device 1 (Yes at 730), the personal mobile device 1 may return to step 713 to continue identifying the surroundings of the personal mobile device 1. If there is no other object to which a hand signal is to be sent around the personal mobile device (No at 730), the personal mobile device 1 may proceed to the end.

[0242] Figure 8 is a flowchart of a method for controlling a personal mobile device according to another embodiment of the present invention.

[0243] The method starts with the state that the personal mobility device 1 is traveling ( 810 ). This state can be determined by the personal mobility device 1 .

[0244] The personal mobile device 1 may determine that the user who has boarded the personal mobile device 1 has performed a hand signal corresponding to the first hand signal information ( 820 ).

[0245] The personal mobile device 1 may identify changes in surrounding conditions within a predetermined range based on the personal mobile device 1 (830). The personal mobile device 1 may detect a speed value to see if the speed of the personal mobile device within the predetermined range has changed. In addition, the personal mobile device 1 may detect a GPS value to see if the GPS of the personal mobile device within the predetermined range has changed.

[0246] If there is a change in the detected speed value and GPS value, the personal mobility device 1 may determine that the surrounding conditions of the personal mobility device 1 have changed (Yes at 830 ).

[0247] When the surroundings of the personal mobile device 1 change (Yes at 830 ), the personal mobile device 1 may check whether the surroundings have changed to correspond to the first hand signal ( 840 ).

[0248] If the surrounding conditions of the personal mobile device 1 have not changed (No at 830) or if the surrounding environment has not changed to correspond to the first hand signal (No at 840), the personal mobile device 1 may generate second hand signal information for executing the first hand signal again (850).

[0249] The second hand signal may include the first hand signal information, and the second hand signal information may include feedback information for proposing to perform the first hand signal again.

[0250] The user who has boarded the personal mobility device 1 may execute a second hand signal corresponding to the second hand signal information ( 860 ).

[0251] Meanwhile, the disclosed embodiments may be implemented in the form of a recording medium storing instructions executable by a computer. The instructions may be stored in the form of program code, and when executed by a processor, the instructions may generate a program module to perform the operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.
