[0043] Embodiments of the invention will now be described with reference to the accompanying figures. The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive manner, simply because it is being utilized in conjunction with a detailed description of certain specific embodiments of the invention. Furthermore, embodiments of the invention may comprise several novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the inventions herein described.

[0044] As used herein, the terms “golf GPS device” and “device” may be used interchangeably. Further, as used herein, the terms “player,” “user,” and “player-user” may be used interchangeably.

Golf GPS Device with Clip

[0045] A golf GPS device including an integrated clip is typically clipped with a golfer's headwear or waist belt. In a golf GPS device including a display screen, when the device is clipped with the golfer's headwear such as a cap or hat, it would be difficult for the golfer to read the information displayed on the display screen because the display screen would likely face away from the golfer's eyes. In such a situation, the battery power of the golf GPS device will be wasted for the time when the golf GPS device is clipped with golfer's headwear. It would be better to turn off the display screen when the golf GPS device determines that it is clipped with the golfer's headwear.

[0046] Also, when the golf GPS device is clipped with the golfer's waist belt, it would be difficult for the golfer to read information displayed on the display screen because the information would be upside down for the golfer's eyes. It would be helpful for the golfer to read the information if the information displayed on the display screen is displayed upside down when the golf GPS device determines that it is clipped with the golfer's waist belt.

[0047] Further, some golf GPS devices with an audio module that generates the sound of certain information about the golf courses and golf plays, such as the distance of the golf GPS device to the green of the hole the golfer is playing. Sometimes such a golf GPS device is carried near the golfer's ears. In other times such a golf GPS device is carried somehow away from the golfer's ears, for example, when the GPS device is kept or clipped with golfer's waist belt. In such a situation, it would be helpful that the golf GPS device turns off the volume of the sound when it determines that it is clipped with the golfer's waist belt.

General Structure and Operation

[0048] In embodiments, a portable information processing and viewing device is provided. Referring to FIGS. 1 and 7, the device includes a body housing a GPS receiver 302, a memory 306, one or more processors 300 and a user interface, the body comprising a front surface and a rear surface. The GPS receiver receives GPS information transmitted from satellites. The memory stores map information or map data 308 of golf courses, each of which includes at least one hole and at least one feature on the hole. The one or more processors determine a distance between the device and a location on a golf course stored in the memory as part of the map information. The user interface provides a user with the determined distance. The user interface includes a display screen 304 on the front surface and a speaker 310 housed in the body.

[0049] In embodiments, the device further includes a clip integrated with the body. The clip includes a spring plate that faces the rear surface of the body of the GPS device. In one embodiment, the clip may be disintegrated from the GPS device. Based on input from one or more sensors or sensing elements, the one or more processors further determine whether something is gripped between the spring plate and the rear surface by spring action of the spring plate. When determining that no object is gripped between the spring plate and the rear surface, the display screen displays the determined distance in a first orientation, and the speaker generates sound at a first volume of the determined distance in response to a user request.

[0050] In embodiments, upon determining that an object is gripped between the spring plate and the rear surface by spring action of the spring plate, the one or more processors cause the user interface to operate in a clip mode, which includes one or more selected from the group consisting of i) not displaying the determined distance on the display screen, ii) displaying the determined distance on the display screen in a second orientation different from the first orientation, and iii) upon a user request, generating sound of the determined distance at a second volume higher than the first volume. Upon determining that the object is ungripped between the spring plate and the rear surface (i.e., the object is disengaged or removed from the spring plate of the clip) the one or more processors cause the user interface to return to the previous state of displaying the determined distance in the first orientation and generating sound at the first volume.

[0051] In embodiments, the one or more processors determine the clip mode based on a user input to the golf GPS device. In another embodiment, the one or more processors determine the clip mode based on information transmitted from one or more sensors, which are discussed below.

[0052] A golf GPS device can be used to track a player's location and ranges in real-time while playing on a golf course. In an embodiment, a golf GPS device comprises a GPS module, processor, memory, input, and output. The GPS module, processor, memory, input, and output can be chosen from ones that are currently well known and commercially available or those that are to be developed in the future. For example, the output can include one or more displays configured to visually convey information and/or speakers configured to verbally convey information. The input can include one or more sensors and/or mechanical, electrical, and digital buttons that facilitate a user to instruct the device to perform certain functions. More than one buttons and/or sensors may be utilized in combination for a particular function.

[0053] It is understood that the various inputs and outputs described herein may be located on any surface of the golf GPS device other than as shown in the depicted embodiments. It is further understood that the various inputs and outputs described herein may be combined into fewer components and that each input and/or output can be configured to perform other functions in addition to those shown in the depicted embodiments.

Golf GPS Device with Automatic Hole Recognition

[0054] Many golf GPS devices now have the feature of automatic hole recognition, which is to determine the particular hole in which the GPS device is located as the user travels along the golf course as the golf play proceeds. For example, the automatic hole recognition feature determines if the location of the GPS device is within a predetermined area or boundary of a particular one of the plurality of holes of golf course. The golf GPS device will include map information of the golf course, which includes the predetermined area or the boundary of such an areas for the automatic hole recognition feature. In such a device, when the user or golfer travels from one hole to another, e.g., from a predetermined area of one hole to a predetermined area of the other hole, the GPS device will automatically recognize the movement of the golfer from one hole to the other.

Golf GPS Device with Playing Hole Determination

[0055] During a play in a hole, sometimes golfers travel to another hole before finishing the play in the particular hole for various reasons. For example, a golfer playing in one hole (e.g., Hole 4) hits by mistake her ball to an area of another hole (e.g., Hole 11) that is adjacent to the hole (Hole 4) she is playing. Then, the golfer travels to the other hole (Hole 11) to complete her play for the playing hole (Hole 4). When the golfer uses a golf GPS device with the automatic hole recognition feature, the GPS device will recognize the other hole (Hole 11) when the golfer travels from her playing hole (Hole 4) to the hole in which her ball is located (Hole 11), e.g., when her golf GPS device enters a predetermined area of the other hole (Hole 11).

[0056] As the golf GPS device recognizes the other hole (Hole 11), the device will automatically compute and display on its screen the distance between the device and the green (or a position on the green) of the other hole (Hole 11). Sometimes this automatic actions of the device may confuse the golfer as the information displayed on the screen is different from what the golfer will likely look for, i.e., the distance between the device and the green (or a portion of the green) of the playing hole (Hole 4). In case the golfer recognizes that the displayed information is not what she is looking for, then the golfer would need to override what the device has done by changing the hole (Hole 11) that the device automatically recognized to the hole (Hole 4) that the golfer is playing. To do that the golfer should know how to change the hole that she is playing in the device. Typically such a change would require multiple actions of the golfer such as changing the currently displayed hole to the next hole (either immediately previous or subsequent hole) of the golf course until the golfer reaches the playing hole. When the playing hole is Hole 4 and the currently displayed hole is Hole 11, the golfer may have to transition the hole from Hole 11 to Hole 10, then to Hole 9 . . . until Hole 4 is displayed.

[0057] In embodiments of the invention, when the golf GPS automatically recognizes the change of holes, then the device automatically determines whether the new hole is immediately subsequent to the previously displayed hole. Further the golf GPS device provides a user interface in which two or more hole numbers are displayed for selection of the golfer. Then, the golfer can select the appropriate hole based on the status of the golf game. In other embodiments, the golf GPS device is equipped with a physical or electronic hot key for returning to the previously played hole when the device recognizes the hole change and has displayed information of the new hole. When the golfer hits the hot key, then the golf GPS device displays the information of the previously played hole.

Predetermined Area

[0058] The predetermined area or boundary for automatic hole recognition feature can vary from hole to hole. In embodiments, the predetermined area covers only a portion of a particular hole or covers substantially all area of a particular hole. In some embodiments, the predetermined area covers certain portions of a particular hole in which typically golfers travel when advancing to the next hole during golf plays. In some embodiments, the predetermined area of a hole covers the tee-off area of the hole. In some embodiments, one hole may have more than one predetermined area.

[0113] In embodiments, the map information includes geographical or locational information of features of golf holes. Referring to FIG. 10, holes 400 and 450 comprises a greens 404 and 454 and a tee-off areas 402 and 452. Map information of each hole comprises locational information of the green 404 or 454 and locational information of the tee-off area 402 or 452 and the hole number pre-assigned to that hole. The feature of the first hole 400 comprises a position of or associated with the green 404 of the first hole 402, wherein the position of or associated with the green 404 is predetermined and included in the map information of the first hole 400 or chosen by a predetermined algorithm at the time of computing the first distance.

[0114] In embodiments, each hole map information comprises a predetermined area defined with a boundary line or boundary lines on a map of that hole 400 or 450. The boundary line or lines of the predetermined area does not accurately follow the boundary of the hole as published by the golf course. The predetermined area is used for determining whether the device is located within the hole such that when the device is located within the predetermined area of the second hole, then the processor determine that the device is located in the second hole 450.

[0115] In embodiments, the predetermined area of each hole does not encompass a portion of the hole. The processor may determine that the device remains located in the first hole 400 once the device is within the predetermined area of the first hole 400 and leaves the predetermined area of the first hole 400 as long as the device does not enter the predetermined area of another hole, for example hole 450

[0116] In embodiments, the processor may determine that the device has moved from the first hole 400 to the second hole 450, when the device travels from a location within the predetermined area of the first hole to outside the predetermined area of the first hole, and then enters the predetermined area of the second hole.

Unintended Playing Hole Change

[0117] In some situations, a player, while playing on hole X (400 in FIG. 10), accidently hits the ball to the course of hole Y (450 in FIG. 10) before completing playing on hole X. In certain situations, hole Y is the subsequent hole after hole X. However in other situations, hole Y is simply a neighboring hole or a hole that is close to hole X and not the subsequent hole. In some embodiments, once the player moves to the location of the ball on hole Y, the golf GPS device will automatically recognize that the device is now located on the course of hole Y. The golf GPS device will further begin to determine distances between the device's current location on hole Y and various features along hole Y, such as those discussed above. However, because the player has not yet completed hole X, the player would rather want to know distances between the player (or the device) and various features of hole X.

[0118] In an embodiment, the player-user can manually select hole X on the device as to instruct the device to determine and report distances from the device to various features of hole X. However, this can be time consuming and/or inconvenient depending on the manual selection system, especially if the user has to scroll through a list of a plurality of holes to select hole X.

User Selection of Playing Hole

[0119] Referring to FIGS. 9 and 10, in embodiments, in order to allow a user to select hole X on the device, the processor 300 of the golf GPS device is configured to repeatedly determine in which one of the plurality of holes the device is located, and to determine if the device has moved from a first one 400 of the plurality of holes to a second one 450 of the plurality of holes. Once determined that the device has moved from the first hole 400 to the second hole 450, the processor determines whether or not the second hole is immediately subsequent to the first hole in terms of the pre-assigned hole numbers of the first and second holes in the golf course. When determined that the second hole 450 is not immediately subsequent to the first hole 400 in terms of the pre-assigned hole numbers of the first and second holes in the golf course, the processor causes to display for selection by a user the hole numbers of the first and second holes on the display screen as shown in FIG. 7. Upon the user's selection of the hole number of the first hole 400, the processor computes a distance between the device and a feature 404 of the first hole 400 and causes to display the computed distance on the display screen and the hole number of the first hole 400 as illustrated in FIG. 8.

[0120] When the user select the second hole 450, the processor computes a distance between the device and a feature 454 of the second hole 450 and causes to display the computed distance on the display screen and the hole number of the second hole 450.

Automatic Change to Next Hole

[0121] With continuous reference to FIGS. 9 and 10, when determined that the second hole, 450 is immediately subsequent to the first hole, the processor determines if the device has stayed within a predetermined zone 408 of the first hole 400 before moving to the second hole 450. When determined that the device has not stayed within the predetermined zone 408, the processor computes the first distance between the device and the feature, for example, the green 404 of the first hole 400 and causes to display the computed first distance on the display screen,

[0122] For this, the map information of the holes 400 and 450 include the predetermined zones 408 and 458, which comprise an arbitrarily defined area on a map of the corresponding hole. The areas encompass one or more features of hole, for example, at least part of the green 404, a golf cart paths 406 and 456 next to the greens 404, 454, an area adjacent the green 404, and an area surrounding the green 404. The zone 408 includes the green 404. Alternatively, the zone 458 exclude the green 454 while surrounding the green 454. In embodiments, the predetermined zones 408 and 458 do not include tee-off areas 402 and 452.

[0123] In embodiments, when determined that the second hole is immediately subsequent to the first hole 400, the processor determines if the device has stayed within a predetermined zone 404 of the first hole for a predetermined period or longer before moving to the second hole 450. When determined that the device has stayed within the predetermined zone 404 for the predetermined period or longer, only then the processor computes a distance between the device and a feature 454 of the second hole 450 and causes to display the computed distance on the display screen,

Hot Key Function

[0124] In some embodiments, the golf GPS device includes a hot key or some other unique input that the user can select or otherwise input to accelerate this process. Upon receiving input to trigger the hot key feature, the golf GPS device can automatically identify the immediately previous hole where the device was located without having to go through other holes intervening between holes X and Y in order. The golf GPS device can further determine and convey to the user information related to features of the immediately previous hole, such as but not limited to distances between the device's current location to various features of the immediately previous hole.

[0125] In certain embodiments, upon receiving such unique input, the golf GPS device determines whether the immediately previous hole was completed or not. In order to do so, in some embodiments, the device can determine one or more of whether the device was within a certain distance of the hole cup of the immediately previous hole and whether the device was ever located on the green of the immediately previous hole. If the device determines that it was, then in certain embodiments, the device confirms that the player accidently moved to another hole before completing the previous hole.

[0126] This hot key function is not limited to golf GPS devices of any particular type. Rather, the hot key function may be incorporated into any type of golf GPS device. For example, any of the golf GPS devices illustrated in FIG. 5B 502, 504, 506, 508 can comprise the hot key function described herein.

Hot Key Input

[0127] In an embodiment, the hot key is a single button that is located on the front surface, the back surface, or the circumferential surfaces. In another embodiment, the hot key is a plurality of buttons that a user has to press or otherwise select. Such plurality of buttons can be located on the front surface, the back surface, or the circumferential surfaces. In certain embodiments, individual buttons of the plurality of buttons can be located on different surfaces among the front surface, the back surface, and the circumferential surfaces. For example, in an embodiment, a user can press the main button 104 and the position mark button 108 together at the same time to trigger the hot key function.

[0128] Further, in an embodiment, the hot key is not a physical button but is a unique pressing pattern on a touchscreen input located on the golf GPS device. In some embodiments, the display itself is a touchscreen upon which a user can input the unique pressing pattern to trigger the hot key. In certain embodiments, the unique pressing pattern can be a unique sliding motion, a unique tapping motion, or a unique combination of any touch screen input.

No Hot Key Input

[0129] In an embodiment, the golf GPS device does not comprise a hot key but is configured to automatically perform the hot key function under particular circumstances. For example, in some embodiments, when the golf GPS device detects that the location of the device has moved from a point on hole X to hole Y, the golf GPS device is configured to determine whether hole Y is the immediately subsequent hole in order. In some embodiments, if hole Y is not the immediately subsequent hole in order, then the hot key function is automatically triggered. In certain embodiments, if hole Y is the immediately subsequent hole in order, then the hot key function is not triggered.

[0130] In certain embodiments, when the golf GPS device detects that the location of the device has moved from a point on hole X to hole Y, the golf GPS device is configured to determine whether hole X was completed by one or more methods described above. In some embodiments, if the golf GPS device determines that hole X was not completed, then the hot key function is automatically triggered. In certain embodiments, if the golf GPS device determines that hole X was completed, then the hot key function is not triggered.

[0131] In some embodiments, the hot key function is automatically triggered when the golf GPS device determines that hole Y is not the immediately subsequent hole to hole X in order and that hole X was not completed. In other embodiments, the hot key function is automatically triggered when the golf GPS device determines that hole Y is not the immediately subsequent hole to hole X in order or that hole X was not completed.

Dynamic Green View

[0132] In an embodiment, the golf GPS device displays a view of the green of the hole where the device is currently located. In general, depending on the location of the player relative to the green, the view of the green as seen from the player's point of view will be different. In some embodiments, the golf GPS device automatically determines the direction from which the player will be approaching the green and tilts the display of the green accordingly on the display. In other words, the golf GPS device displays the view of the green as seen from the player's location.
