User Input Selection Device and Automated Bowling Coaching System in an Automatic Bowling Scoring System

This invention relates generally to bowling scoring systems and, more particularly, to bowling scoring systems having a graphic user interface. More particularly, the invention relates to a user interface that is intuitive in use and provides helpful information to the bowler.

Automatic scoring systems for bowling centers have been provided which respond to outputs produced by a pin-fall monitor in order to automatically score each bowler's game. The automatic scoring system typically includes a scoring console having a keyboard and a CRT display for entering the names of the bowlers, correcting scoring errors, and the like. The CRT display may also display video images, including the scores of the bowlers, as well as various other materials such as exciter graphics, instant replay of the bowler, and the like. Such systems typically include overhead monitors, which display the same video displayed on the scoring console display, in order to allow viewing by a larger group including other bowling teams, spectators, and the like. One such system is disclosed in commonly owned U.S. Pat. No. 5,255,185 for a BOWLING CENTER VIDEO DISPLAY SYSTEM, the disclosure of which is hereby incorporated herein by reference.

In addition to the above-described functions, the scoring system typically includes special features intended to assist the bowler in improving his or her score as well as specialized features such as the ordering of food and beverage service. The inclusion of all such functions in a bowling scoring system results in a proliferation of the number of entries that must be selected by the bowler in order to operate the bowling scoring system to its fullest capacity. Indeed, if each option were assigned to a discrete input key, the input keypad would require more than 125 keys.

One approach to reducing the number of selection keys required has been to organize the selections into various menus. The menu system operates as follows. The user selects a general function to be performed and is then presented with a number of possible selections. A selection is entered by a key that is associated with the selection by a number or letter on the keyboard. The selection will then generate another sub-menu requiring a further selection by the user. Typically, up to four menu levels are required in order to provide all of the user inputs to carry out a particular function. While such menu structures have reduced the number of keys on the keyboard, they are often confusing and cumbersome to operate. The result is that the user is not always able to achieve the desired function and spends an excessive amount of time attempting to achieve the attendant function.

One of the known functions for assisting a bowler in improving his or her score is to indicate to the bowler, after the bowler has thrown the first ball, the contact area where a second ball should contact the pattern of pins standing after the first ball in order to convert the leave. Such indication is typically provided at the curtain area above the pinsetter in the form of an illuminated arrow juxtaposed with an illuminated display of the leave. Such spare-conversion aid provides the minimum amount of information that is useful in assisting the bowler in converting the leave.

The present invention provides a bowling scoring system having a unique graphic user interface that is both intuitive and straightforward in operation, as well as providing special features for assisting the bowler in improving his or her score.

A bowling scoring system, according to a first aspect of the invention, includes a user input selection device for receiving user input selections. The input selection device includes a controller with a program having various program states. The controller is responsive to the state of the program for performing a particular one of a plurality of functions. A plurality of input selection keys are juxtaposed with the display device for providing inputs to the controller. A plurality of key indicia areas are provided on the display device, each of the areas are associated with one of the input selection keys. The controller is responsive to the state of the program for displaying a particular label in at least one of the indicia areas and for performing a function associated with the display area in response to actuation of the input selection key associated with the labeled indicia area. This "soft-key" feature provides an effective technique for receiving user input selections without requiting the large number of sub-menu layers required in the prior art input selection devices. The input selection keys and the key indicia areas are preferably distributed across the bottom of the display device. In this manner, the functions are readily available for selection by the user at all times. In particular program states, two of the input selection keys are provided for causing scrolling of selection items displayed on the display device.

This allows an exceptionally flat selection structure, which is intuitive to use and results in the user being able to carry out the intended selection.

A bowling scoring system, according to another aspect of the invention, includes a bowler coaching device for advising a bowler of a strategy for converting a leave. The coaching device includes a leave identification means responsive to the pin-fall sensor for determining the identity of a pattern of pins standing after a bowler rolls a first ball. A conversion analysis means is provided that is responsive to the leave identification means for determining the contact area where a ball should contact the pattern of pins standing in order to convert the leave. The conversion analysis means further determines bowler actions required in order to place the ball in the contact area; for example, the location of a target portion, or board, of the lane where the ball should be delivered in order to place the ball in the contact area as well as location of a placement of the bowler's feet at the start of the bowler's approach required to deliver the ball to the target portion of the lane. The bowler coaching device further includes a display generation means that is responsive to the conversion analysis means for causing the display device to display the contact area and the bowler actions required for the pattern of pins standing after the bowler rolls the first ball. Preferably, the graphic generation means generates an image of the pattern of pins and a ball in the contact area. The image may be a graphic image stored in the controller's memory. The coaching device may further include input means for receiving a user selection of the hand used by the bowler to deliver the ball. The controller determines and displays the bowler's action as a function of the hand used by the bowler to deliver the ball. A bowler coaching device, according to this aspect of the invention, may further include information regarding the difficulty of converting the leave, as well as information whether the leave is considered a split.

Referring now specifically to the drawings and the illustrative embodiments depicted therein, the bowling center illustrated in FIG. 1 includes an automatic scoring system 20 including a scoring processor 22 (FIG. 2) and a plurality of scoring consoles 24. Automatic scoring system 20 may additionally include a plurality of overhead monitors 26 in order to display the same images displayed on displays 28 associated with each scoring console 24. However, the images displayed on overhead monitors 26 are not limited to those displayed on scoring consoles 24. For example, if overhead monitors 26 are grouped into three units for each pair of lanes, as illustrated in FIG. 1, then two of the three monitors may display the same graphic images as the scoring consoles 24 associated with the two lanes with the third monitor displaying other graphic images, such as a television program, video recordings, or the like.

In the illustrated embodiment automatic scoring system 20 utilizes an open architecture which allows assembly of the system substantially from off-the-shelf components, utilizing an ISA bus standard and an Ethernet communication network. In this manner, the scoring processor may be readily upgraded for enhanced microprocessor technology and the communication system is supported by industrial standard communication technology. Each scoring processor 22 includes a mother board 30 having off-the-shelf components, such as a 486 processor 32, a PC/AT chip set 34, and other conventional components 36a-36d. A mother board bus 38, which has a protocol according to ISA standards, supports a multiplexed graphics interface card 40 for supplying video signals to displays 28 for a pair of scoring consoles 24, as well as a pair of overhead monitors 26. Mother board bus 38 additionally interfaces with a scorer interface card 42, which, in turn, provides interface with a pair of scoring consoles 24 for data other than graphic and audio data. A pair of sound cards 44 provide interface between ISA bus 38 and microphones 60 in a pair of scoring consoles 24. An Ethernet card 46 interfaces ISA bus 38 with a 10 Base T hub utilizing standard Ethernet protocol. Each scoring console 24 includes a micro-controller 48 in order to receive inputs from a keypad 50 or a touch-screen 54 and to communicate with scoring processor 22. Micro-controller 48 additionally receives inputs from a card reader 52. A multiplexer 56 allows a microphone 58 and a speaker 60 to be utilized with either a stereo input channel received from a sound card 44 or from an intercom multiplexer 62.

Intercom multiplexer 62 multiplexes each microphone/speaker combination of each console 24 onto one of four intercom lines 64a-64d (FIG. 3). Each intercom line 64a-64d is connected to a speaker phone 66a-66d at a central control console 67. In this manner, a request for intercom connection at any console 24 may be intercepted by any speaker phone 66a-66d. This allows more than one intercom request to be serviced at a time, thus avoiding the necessity for stacking requests.

Scoring console 24 includes a plurality of unlabeled user input selection buttons or switches 68a-68h, which are distributed along the bottom of a display surface 70 (FIG. 4). Display 70 is illustrated in FIG. 4 displaying a score-sheet for six bowlers including the name of the current bowler at 72, as well as the handicap 74 and average 76 of each bowler. Display surface 70 additionally includes a plurality of indicia areas 78a-78h, which are juxtaposed with the input keys 68a-68h. In the embodiment illustrated in FIG. 4, input keys 68a-68h are mechanical key switches which are located on scoring console 24 adjacent to display surface 70. In FIG. 5, a much-screen display surface 70' includes a combination of user selection keys 68a'-68h' directly overlaying the associated indicia areas 78a-78h. Each key indicia area 78a-78h includes an indicia that prompts the user of the function performed by the corresponding selection key 68a-68h, 68a'68h'. As will be set forth in more detail below, the indicia in each indicia area is established by the state of the software operating controller 48. Likewise, the function carried out by actuation of each of the selection keys changes dependent upon the state of the software of the micro-controller 48. This soft-key specification of the function of each key provides a unique input selection system.

Operation of the soft-key display is controlled by a soft-key routine 80 (FIG. 6). For each pass through routine 80, beginning at 82, the control determines whether each of the indicia areas is blank or empty at 84. If the area is not blank, then the soft-key label is stored in the specific indicia area at 86 and the function associated with the specific key is set at 88. The monitor display is refreshed and the associated function enabled at 90. If it is determined at 84 that the label is blank, then the soft-key label for the particular indicia area is removed at 92. The associated function is removed at 94 and the monitor display is refreshed at 90.

The soft-key system enables the program of micro-controller 48 to set and change the text label for each key 68a-68h, 68a'-68h' and its subsequent function at any time depending on the state of the program. The soft-key routine 80 matches the keyboard input with the soft-key map and performs the specific function when the key is actuated by the user. The soft-key is set up by displaying the soft-key label and enabling the specified function for the soft-key. During the execution of the software, a soft-key may change its meaning and subsequent action any number of times.

One state of the soft-key indicia is illustrated in FIG. 7, wherein soft-key indicia area 78c displays an upward-directed arrow and soft-key indicia 78d displays a downward-directed arrow. The associated keys (not shown in FIG. 7) provide scrolling of a cursor bar 82 on an image of possible selections superimposed over the bowler's score-sheet. If more selections are available than conveniently fit within the display area 84, the list of potential selections will scroll upward or downward when cursor bar 82 reaches, respectively, the downwardmost or upwardmost position as illustrated in FIG. 7. It is also noted by reference to FIG. 7 that indicia areas 78b, 78e, and 78f are blank. There is no function assigned to the keys associated with such indicia areas. Accordingly, the display is blank for these keys. Indicia areas 78a, 78g, and 78h are associated with keys that perform the same function for most of the states of the program as will be described in more detail below. As such, the indicia associated with the keys remain in their same locations for all such program states. FIG. 8 is similar to FIG. 7 except that the program is in a different state. However, the soft-keys are assigned the same functions and indicia as in FIG. 7 but for a different purpose; namely, selecting the scorer display format rather than the display language. FIG. 9 illustrates a different program state, which provides an on-screen calculator for use by the bowlers. Display areas 78b-78g display indicia related to calculator functions. The keys (not shown in FIG. 9) associated with these indicia areas carry out the functions illustrated within the respective indicia areas.

The soft-key routine 80 performs eight main functions illustrated in a main score-sheet display key-set 86, which is provided on display 28 unless a specific soft-key function is being entered. Key-set 86 includes function select keys for a contact sensitive help screen select key 88, an add/change bowler select key 90, a change score select key 92, a move arrows select key 94, a special features select key 96, a bowler track select key 98, an instant-replay select key 100, and a food and beverage select key 102 (FIGS. 10A, 11A, 12A, 13A, and 14A). When the user actuates the help select key 88, a context sensitive help screen key-set 104 is displayed by indicia areas 78a-78h (FIGS. 10A and 10B). Key-set 104 includes a help index key 106, which, when actuated, provides a key-set 108 and displays on the display 28 a group of selectible items. Within key-set 108, an up arrow select key 110 and a down arrow select key 112 provide scrolling of a highlight bar on the display. A view key 114 allows the user to view details of the item highlighted by the highlight bar. A cancel key 116 allows return to the main key-set 86. When in key-set 108, actuation of a help key 118 selects a key-set 120, which is blank except for a cancel key 122 which returns the user to the key-set 104. When in key-set 108, actuation of a search key 124 calls up a key-set 126 including a left arrow key 128, which, when actuated by the user, moves the cursor to the left. An OK select key 130 returns to the help index screen and selects the item highlighted by the highlight bar. A cancel button 132 returns to the help index key-set 108. When in the general help index search window key-set 126, actuation of a help key 134 provides a key-set 136, which includes a cancel key 138, which returns to the help index search key-set 126.

Context sensitive help screen key-set 104 additionally includes a key 140, which indicates to one or more front desks (not shown in FIG. 10A) that two-way intercom communication is desired. Actuation of a service key 142 indicates that service is requested by changing the background color of display 28. An up arrow key 144 and a down arrow key 146 scroll a highlight bar in opposite directions among a group of possible selections displayed on display 28.

When a user selects bowler key 90 from the main score-sheet display key-set 86, an add/change bowler information key-set 150 is displayed in indicia areas 78a-78h (FIGS. 11A and 11B). Key-set 150 includes a help key 152, which, when selected, causes display of context sensitive help key-set 104 which was previously described. Key-set 150 includes an add key 154, which, when activated, causes display of an add/change bowler key-set 156 (FIG. 11B). In addition to a help key 158, which provides access to context sensitive help key-set 104, key-set 156 includes a previous bowler key 160 and a next bowler key 162, which moves a cursor to the previous or next bowler displayed on display device 28. A left arrow key 164 and a right arrow key 166 allow movement of the cursor, respectively, left or right. A next field key 168 advances the cursor to the next field for the current bowler. An OK key 170, when selected, updates the bowler file and returns to main score-sheet display key-set 86. A cancel key 172 returns to the score-sheet display key-set 86 without updating the bowler's file.

Add/change bowler information key-set 150 includes a remove key 174, which, when actuated, causes display of a remove bowler key-set 176.

Add/change bowler key-set 150 additionally includes a move key 188, which, when actuated, causes display of a change bowler position key-set 190. Change bowler position key-set 190 includes a previous bowler key 192, which moves the highlighted bar up one bowler, and a next bowler key 194, which moves the highlight bar down one bowler. An OK key 196, when actuated, causes a reordering of the bowlers in the manner selected by keys 192 and 194 and return of the program to the score-sheet display key-set 86. A cancel key 198 causes direct returns to the score-sheet display 86.

Scores key 92 on main score-sheet display key-set 86 causes a change scores key-set 202 to be displayed in indicia areas 78a-78h (FIGS. 12A-12C). The change score key-set includes a change score key 204, a move score key 206, and an erase score key 208. Key-set 202 additionally includes a help key 210 and a cancel key 212, which perform functions similar to those functions previously described. Change score key 204, when actuated, calls up a change scores frame key-set 214 (FIG. 12b). This key-set includes a left arrow key 216, a previous bowler key 218, a next bowler key 220, and a right arrow key 222, along with help, OK, and cancel keys. All of these keys perform functions similar to those previously described. However, the selection items displayed on display device 28 are related to changing a bowler's score for a particular frame. When an OK key 224 is actuated, upon the cursor being at the desired location on the displayed selection items, a frame correction key-set 226 is displayed. In addition to help, OK, and cancel keys, frame correction key-set 226 includes a left arrow key 228, a previous bowler key 230, a next bowler key 232, and a right arrow key 234, which moves a cursor among selection items displayed on display 28. An undue key 236 allows a previous correction to be returned to an original state while an OK key 238 carries out the selected correction.

Selection of move score key 206 calls up a move score key-set 240 (FIG. 12a). Key-set 240 includes a left arrow key 242, a previous bowler key 244, a next bowler key 246, and a right arrow key 248, which moves a cursor among selection items displayed on display 28 in a manner previously described. An OK selection key 250 in key-set 240 calls up a move scores key-set 252 in order to take action with respect to the selected item on the display (FIG. 12c). Move scores key-set 252 includes a left arrow key 254, a previous bowler key 256, a next bowler key 258, and a right arrow key 260 in order to allow the user to move the cursor among selection items displayed on display device 28. When the desired selection item is highlighted, actuation of an OK key 262 causes the highlighted score movement to be carried out. A cancel key 264 returns the program to the score-sheet display key-set 86.

Actuation of erase score key 208 calls up an erase-a-frame key-set 266, which includes a left arrow key 268, a previous bowler key 270, a next bowler key 272, and a right arrow key 274, which performs functions previously described. An OK key 276 carries out the selection highlighted by the cursor by movement of keys 268-274 and advances the program to display the score-sheet display key-set 86. A cancel key 278 returns to the score-sheet display key-set without carrying out the highlighted action.

When the user selects the arrows key 94 from score-sheet display key-set 86, a moves arrow key-set 280 is called up and displayed on display 28 (FIGS. 13A and 13B). In addition to help, up arrow, down arrow, OK, and cancel keys, which function in a similar manner to that previously described, but on the selection items displayed on display 28, the move arrows key-set includes a tardy key 282 and a bowl-out key 284. When tardy key 282 is selected, a tardy key-set 286 is called up and displayed on display 28. The tardy bowler key-set 286 includes a previous bowler key 288 and a next bowler key 290, which moves the highlighted bar in opposite directions among the displayed bowlers. Selection of an OK key 292 causes the highlighted bowler to be tagged and to bowl out of sequence in a manner which will be described. A cancel key 292 causes return to the score-sheet display key-set 86 without any further action. Actuation of the bowl-out key 284 calls up a bowl-out key-set 296, which includes a previous bowler key 298 and a next bowler key 300 which moves the cursor bar in the manner previously described. An OK selection key 302 tags the highlighted bowler in order to bowl out of sequence in a manner which will be described. A cancel key 304 causes the program to return to the score-sheet display 86 without further action.

The tardy function allows a bowler be tagged as tardy, wherein the system will automatically weave that bowler into the line-up of bowlers so that the bowler may catch up without requiring the other bowlers to wait for that bowler to completely catch up. The bowl-out function automatically weaves the selected bowler in the line-up so that the bowler can quickly finish the game without requiring the other bowlers to wait. Both functions are carried out automatically once invoked by selection.

When special key 96 is selected from score-sheet display key-set 86, a special features key-set 306 is called up and displayed on display 28 (FIGS. 14A-14H). In addition to help, OK, and cancel keys, the special features key-set includes an up arrow key 308, and a down arrow key 310, which scrolls among various special feature selection items displayed on display 28. When the desired special selection function is highlighted by the prompting bar, actuation of the OK key 312 causes a key-set to be called up which provides selections relevant to the selected special feature. These include a bowler statistics key-set 314, which allows call-up and selection of statistics relevant to each of the bowlers, an exciter graphics key-set 316, which allows the user to turn the exciter graphics on or off, a language selection key-set 318, which allows the user to select the language for all screen displays and prompts, a previous games key-set 320, which provides selection keys in order to allow review of previous games bowled by the bowlers utilizing the goring console, a frames display key-set 322, which allows the user to select the number of frames displayed on the display 28, as illustrated in FIG. 8, a display score-sheet key-set 324, which allows review of a score-sheet from another lane, a sequence selection key-set 326, which changes the mode of operation of the sequencer, a TV selection key-set 328, which provides control for a television program displayed on display 28 or overhead monitor 26, a frame scores for strings of strikes 330, which allows selection of the number of frames in which sequential strikes are considered a string, a spare Coach control key-set 332, which allows the user to turn on or off the Coach feature, which will be described below, a bowler sequence key-set 334, which allows a sequence of one frame or two frames to be selected, a lane sequence key-set 336, which controls the lane arrow for matches utilizing a pair of lanes, a calculator key-set 338 for providing a calculator for use by the bowler, as illustrated in FIG. 9, a bowler track control screen 340, which allows a display of the bowler's previous rolled ball to be turned on or off, an instant-replay key-set 342, which allows an instant replay of the bowler's body movement during the previous ball to be turned on or off, a practice control screen 344, which allows the bowler to select various practice formats, and a spare combination key-set 346, which allows the practice mode selected by key-set 344 to be cancelled.

Automatic scoring system 20 additionally has a vacant bowler function that automatically compensates for teams with vacancies without requiring manipulation by the user. The scoring system additionally includes a pre-bowler function which allows a bowler and/or a team to pre-bowl scores for any week of the season. The scores are then automatically selected in the interfaced week of bowling or may be removed if the league or team decides that pre-bowled scores should not be used. Pre-bowled scores are automatically downloaded to the scorer console on the proper bowling night. For leagues that use the sum of individual handicaps, the handicap used on the night for pre-bowls will be placed on the handicapped used at the time the pre-bowl occurred. For leagues that use the sum of of individual handicaps, the handicap will be based upon the previous week's average. The automatic scoring system additionally will automatically compute the correct handicap when a mid-game substitution has occurred. This eliminates the risk of bowler error due to the complex calculation that is used to determine handicap according to conventional rules. The system will also compute the correct absentee score to use if a bowler cannot finish a game. The automatic scoring system 20 additionally includes a bowler personal identification number, which eliminates the need to manually enter substitute bowler information at the scorer console.

Automatic scoring system 20 additionally includes a bowler coaching device, generally designated 350, for advising a bowler of a strategy for converting a leave. Coaching device 350 responds to the output of a pin-fall sensor (not shown), which determines the pattern of pins standing after a bowler rolls a first ball. Bowler coaching device 350 includes a database of 1,023 possible patterns of pins standing after a first ball and including information relevant to each such leave. The information incorporated into each entry in the database is whether each pattern is considered a split and whether the spare is considered a low degree of difficulty, a moderate degree of difficulty, or a high degree of difficulty. The database additionally includes information regarding the placement of the target, or the position of the mid-lane, where the ball should pass. This value is measured in boards, the bowler should move the target from the previously delivered ball. Each of the records in the database additionally includes the placement of the feet, or position that the bowler should start the approach, which is also described in boards with respect to that of the initial delivery. The database additionally includes an entry of the contact area where the ball should contact the pin. The above-described information for each entry in the database is replicated for both left-handed and right-handed bowlers. A graphic display generally indicated at 352 is shown on display 28 and/or on overhead monitor 26 automatically after the bowler has rolled the first ball of a frame unless the feature is turned off (FIG. 15). The interface includes a graphic illustration area at 354 of an image of the pattern of pins standing and a ball in the contact area. The interface additionally includes a field 356, which indicates whether the particular bowler is a right-handed bowler or a left-handed bowler, a field 357, which indicates if the leave is considered a split display field 358, which indicates the degree of difficulty of the conversion, a display field 360, which displays the number of boards to be moved for placement of the target position, and a field 362 for displaying from the database the board movement for feet placement of the bowler.

The information displayed on graphic display 352 is generated by a display program 364 (FIG. 16). After the micro-controller 48 has retrieved the database entry corresponding to the pattern of pins left standing after the bowler rolls the first ball, the routine determines at 366, from information previously entered by the bowler in the scoring console, whether the bowler is a right-handed bowler. If the bowler is a right-handed bowler, the controller displays at 368, in field 360, the target position text in the database record for right-handed bowlers. The control then displays at 370, in field 362, the feet position for right-handed bowlers. The control displays at 372, in display 354, the graphic image relevant to a ball rolled by a right-handed bowler. If it is determined at 366 that the bowler is not a right-handed bowler, then the bowler is a left-handed bowler. The control then displays at 374, in field 360, the target position for a left-handed bowler and displays at 376, in field 362, the feet position for a left-handed bowler. The control displays at 378, in display area 354, a graphic image of the area of where a ball should be delivered in order to place the ball in the contact area.

The control then displays at 380, in field 358, the level of difficulty text from the selected file. It is then determined at 382, from the entry in the database file, whether the leave is considered a split. If so, it is displayed at 384, in a field 357, that the pattern is a split.
