[0034] The portable device (100), the golf course geographic database (200), and the server (300) are connected to each other through a communication network.

[0035] Here, the communication network refers to a wired and wireless communication network such as the Internet, or a combination thereof. The network is not limited to a particular system and can be interpreted to include both a conventional internet and a mobile communication networks.

[0036] For example, the portable device (100), the golf course geographic database (200), and the server (300) may be connected to each other through a combination of various conventional communication networks, such as an internet network or a mobile communication network. The way how they are connected to each other is not limited to a particular way.

[0037] The golfer downloads a smart golf course round information provision application; installs it on the portable device (100); runs it to get an access to the smart golf course round information provision system (1000); and can receive a smart golf course round information provision service.

[0038] Hereinafter, the golf course round information provision system (1000) according to an embodiment is described.

[0039] The portable device (100) is attached to a body of a golfer. For example, the portable device (100) is accommodated in a carrier and the carrier is attached to the golfer's body. The portable device (100) may include a motion sensor (110) and a global positioning system (GPS) (120). The portable device (100) may further include additional components performing various functions. The motion sensor (110) may include an acceleration sensor (111) and a gyroscope sensor (112). The carrier may be a strap or a bag.

[0040] The golf course geographic database (200) stores geographic data of a golf course where a golfer is playing. The golf course geographic data includes golf course topography data, layouts, locations of hole cups, etc.

[0041] The server (300) receives motion data from the motion sensor (110) of the portable device (100) in real time, detects a golfer's swing motion, and extracts golf course geographic data from the golf course geographic database (200).

[0042] The server (300) receives the GPS location information from the GPS (120) of the portable device (100), and calibrates the location of the portable device (100) using the golf course topography data and the GPS location information.

[0043] After play in a given hole ends, the portable device (i) calculates a play score of the golfer based on the number of swing motion of the golfer which is detected by the motion sensor (100), and (ii) transmits the score to the server (300). The server determines (i) whether and where a penalty stroke occurs, and (ii) where the penalty stroke (i.e., a penalty location) occurred. Then, the server stores the penalty location.

[0044] The server (300) determines that an OB penalty stroke occurred when the swing motion is detected twice at a given location within a preset time period.

[0045] The server determines that a hazard penalty stroke occurred when the golfer moves towards a golf cart to retrieve a ball or bends down toward the ground to place a ball on the ground.

[0046] How to define a penalty stroke or how to score the penalty stroke is not limited to the way mentioned above. Instead, how to define a penalty stroke or how to score the penalty stroke can be modified in various ways.

[0047] The server (300) generates rounding information of the golfer and transmits the rounding information to the portable device (100). The rounding information is generated based on the swing motion of the golfer.

[0048] The rounding information may includes a tee shot distance, an out-of bounds (OB) stroke ratio, a hazard stroke ratio, an approach accuracy, and a putting accuracy, or a combination thereof.

[0049] Based on the geographic data and the GPS data, the server (300) provides first strategy information and second strategy information. The first strategy information includes a distance and a height from a current location of the golfer to a hole cup of a given hole. The second strategy information includes how to play on a green of the given hole based on a slope of the green and a hole cup location of the green.

[0050] The rounding information may be a play score of the golfer at the given round of golf play. The rounding information may include a score at a uphill slope hole, a score at a hazard-prone hole, a score at a dog-leg hole, or a combination thereof. Here, the dog-leg hole refers to a hole in such a shape that bends like a dog's hind leg.

[0051] The play score of the golfer may be calculated based on the number of swing motion and the number of penalty stroke of the golfer. FIG. 4 shows how to calculate the play score based on the number of swing motion and the number of penalty stroke of the golfer.

[0052] FIG. 4 is a layout of a golf course for explaining rounding information according to an embodiment of the present invention.

[0053] Referring to FIGS. 1 and 4, the points indicated by the black arrows pointing downward represent the tee points, and the broken lines represent the golfer's movement line. Additionally, the points indicated by the black-colored diamond dots indicates the positions where swing motions were detected, and the points indicated by the gray-colored diamond dot indicates the position where both of a ball releasing motion and a swing were detected. Additionally, black circles represent hole cups.

[0054] Referring to FIG. 4, the first hole (h1) is a par 4 hole, and the golfer scores 5 strokes, which is a bogey play. A bogey play means the golfer made one more stroke than the standard par to put the ball into the hole cup.

[0055] The 2nd hole (h2) is a par 3 hole. 3 swing motions were detected. 1 movement of bending golfer's waist toward the ground was detected to set up the golf ball. Such movement is counted as a hazard penalty. Combining the 3 swing motions and the 1 hazard penalty, the play score at the 2nd hole is counted as a bogey.

[0056] In this way, the server (300) transmits the rounding information to the portable device (100) carried by the golfer. Based on the round information, the golfer can easily figure out his/her golf score at a given hole and at a given round of golf play and improve his/her golf skill.

[0057] FIG. 5 is a flowchart showing a method for providing smart golf course round information based on a motion sensor according to an embodiment of the present invention. More detailed description of S100 to S500 is provided below referring to FIGS. 1 to 3.

[0058] First, the golfer carries the portable device (100) to his/her body and starts playing a golf rounding (S100). The location where the portable device (100) can be attached to the golfer's waist, but the location of the the portable device (100) is not limited thereto. It can be attached to anywhere of the golfer's body.

[0059] After S100, the portable device (100) transmits GPS data and motion data to the server (300) (S200). The server (300) may be installed anywhere, e.g., in the golf course. Preferably, it is can be installed at a golf shop management office that manages golf course facilities.

[0060] After S200, the portable device (100) detects the golfer's swing motion based on the motion data (S300). Through S200 to S300, the server (300) tracks golfer's movement and golfer's swing motion over time. The golfer's movement can be obtained from the GPS location information. The moment of the golfer's swing motion can be obtained from the motion data.

[0061] After S300, the server (300) processes an OB (Out of bounds) penalty stroke or a hazard penalty stoke (S400). For example, the server (300 processes a golfer's movement as an OB (Out of bounds) penalty stoke when the golfer's swing is detected twice within a preset time period at the same location. The preset time period may be 5 seconds, 10 seconds, etc., but is not limited thereto. Additionally, the server (300) processes a golfer's movement as a hazard penalty stroke when it detects that the golfer moves in the direction where a golf cart is located to retrieve a golf ball or that the golfer bends his or her waist to the ground to place a golf ball on the ground.

[0062] Here, OB refers to an area beyond a predetermined boundary of a given golf course or an area marked as such by an entity hosting a given golf game. A hazard refers to a bunker or a natural obstacle area where a level of difficult of golf play is high or impossible. The hazard may be intentionally build in the golf course to enhance difficulty or landscaping of the golf course.

[0063] In addition, for accurate score counting, video information can be used which is obtained using cameras. The cameras can be installed in at least one location within the golf course. The location where the cameras are installed is not specifically limited.

[0064] After S400, the server (300) provides rounding information to the golfer's portable device (100) (S500). Here, the rounding information may include at least one of a tee shot distance, an OB ratio, a hazard ratio, an approach accuracy, a putting accuracy, or a combination thereof.

[0065] The rounding information is a play score of the golfer at the given round of golf play. The rounding information may include a score at a uphill slope hole, a score at a hazard-prone hole, a score at a dog-leg hole, or a combination thereof. The play score of the golfer can be obtained based on (i) the number of swing motion of the golfer, and (ii) the number of a penalty stroke of the golfer.

[0066] The above-described embodiments are provided along with drawings to help understanding the present invention. It should be noted that the embodiments are provided merely for an exemplary purpose. It is apparent that, to a person having an ordinary skill in the art, various other modifications and equivalent embodiments are available from the present invention. It should be noted that the scope of the present invention should be determined by the appended claims.
