This application is a continuation application of commonly assigned U.S. patent application Ser. No. 10/889,985 entitled �METHOD AND SYSTEM FOR DYNAMICALLY LEVELING GAME PLAY IN ELECTRONIC GAMING ENVIRONMENTS,� filed on Jul. 12, 2004 now abandoned, which claims priority to U.S. Provisional Patent Application No. 60/486,672 entitled �METHOD AND SYSTEM FOR AUTOMATIC HANDICAPPING IN ELECTRONIC GAMING ENVIRONMENTS,� filed Jul. 11, 2003, and to U.S. Provisional Patent Application No. 60/577,446 entitled �DVD GAME ARCHITECTURE,� filed Jun. 4, 2004. All of the above applications are incorporated herein by reference thereto.
In some electronic game environments that involve competition between multiple players (typically games requiring motor skill and dexterity), skill level is typically determined at the outset of the game and effects all players of the game. Thus, for example, one of the players can choose to play an �easy� version of a car racing game or more difficult version, etc. To change the skill-based level of play, the game typically requires restarting at a new skill level.
Embodiments of the present invention provide enhanced computer- and network-based methods and systems for automatically and dynamically providing skill-based game content on an individualized basis yet preserving competition between game participants, all within the confines of a single game. Different participants can simultaneously and competitively play the same game at each participant's individual skill level in a manner that is most comfortable to the participant. Example embodiments provide a Dynamic Challenge Level Adjuster (�DCLA� or �Level Adjuster�) for carrying out the techniques for automatically determining game content based upon dynamically adjusted individual skill levels. In one embodiment, the Level Adjuster is included as part of an Electronic Gaming Engine (�EGE�), which provides a runtime environment for electronic games. The DCLA determines an initial skill level index for each participant, either receiving an indication of a skill level from the participant or determining one automatically, for example based upon queries or sample challenges. When automatic adjustment of skill levels is enabled, the DCLA adjusts a skill level index of a participant as the game progresses, for example, based upon the correctness of a response to a prior challenge. When appropriate, the DCLA determines a corresponding challenge level based upon the current skill level index of a participant, and uses the determined challenge level (or the skill level index) to automatically select a next challenge to be presented to the participant.
Embodiments of the present invention provide enhanced computer- and network-based methods and systems for automatically and dynamically providing skill-based game content on an individualized basis yet preserving competition between game participants within the confines of a single game. The encompassed techniques �level the playing field� between the participants, thus enhancing the overall competitive environment provided by the game. In this way, different participants can simultaneously and competitively play the same game at each participant's individual skill level in a manner that is most comfortable to the participant. For example, an adult can compete with a young child in a trivia-based contest and both experience a constructive level of challenge while playing each other.
Example embodiments provide a Dynamic Challenge Level Adjuster (�DCLA� or �Level Adjuster�) for carrying out the techniques for adjusting game play content. In one embodiment, the DCLA is included as part of an Electronic Gaming Engine (�EGE�), which provides a runtime environment for electronic games. The EGE provides the basic components needed to integrate different types of challenges, for example, multiple-choice question and answer challenges, into an electronic game. Games that are created using the EGE therefore automatically provide multi-player skills-based game play based upon an individual's skill level. One skilled in the art will recognize, however, that a DCLA can be integrated into games other than those created using an EGE and into other game environments and gaming engines.
The term �skill level� refers to some measure of skill of a participant. It may be a measure of various age criteria, experience criteria, or knowledge criteria, etc. A �skill level index� or �handicap index� is some indication of a participant's skill level. In some embodiments, it may be treated as disadvantaging the more skilled players; in other embodiments, it may be treated as advantaging the less skilled players.
The term �challenge level� refers to the level of the challenges (game content) presented by the game, and, depending upon the particular implementation, may or may not map directly to participants' skill levels. For example, challenges may be grouped into different levels, yet each challenge level may map to a range of skill levels. Each game provides logic regarding how a participant is moved between skill levels and, potentially, between challenge levels. In one embodiment of a DVD-based game called TimeTroopers�, three challenge levels, �cadet,� �captain,� and �commander,� are mapped to ranges of skill levels (from 0-14). In that game, as each challenge is answered, the participant's skill level increases for correct answers and decreases for incorrect answers. When the participant's skill level crosses a challenge level �boundary� (for example moves from skill level 4 to skill level 5), challenges from the group of challenges associated with the next harder challenge level are presented by the game. One skilled in the art will recognize that many different variations of mapping skill levels to challenge levels can be created and many different logic paths for how movement between skill levels and between challenge levels is accomplished. It is contemplated that the techniques of the present invention can be incorporated into any such scheme.
FIG. 1 is a block diagram of components an example Electronic Gaming Engine including a Dynamic Challenge Level Adjuster. In one example embodiment, the Electronic Gaming Engine comprises one or more functional components/modules that work together to provide game flow, game content, dynamic adjustment of skill and/or challenge level, scoring, and other capabilities. One skilled in the art will recognize that these components may be implemented in software or hardware or a combination of both. The example EGE illustrates how a DCLA may be integrated into an electronic game environment or game engine. In FIG. 1, an Electronic Gaming Engine comprises game flow logic 101; game content models, for example, question and answer (�Q&A�) challenge models 102; a dynamic challenge level adjuster (�DCLA�) 103; one or more scoring modules 104; challenge data 105; participant (player) data 106; and an input/output interface 107. The game flow logic 101 provides the flow of the game, from participant to participant, from round to round. It selects appropriate game content using the challenge models 102, the challenge data 105, and the participant data 106; presents the selected content via interface 107; invokes the DCLA to adjust the skill level for a current participant; and scores the participant's responses using scoring module(s) 104, storing the new scores in participant data 106 and advancing or retreating the participant as indicated on a scoreboard.
In one embodiment of the EGE, the scoreboard is an electronic scoreboard, such as that described in U.S. Provisional Application No. 60/577,446, entitled �DVD Game Architecture.� One skilled in the art will recognize, however, that the EGE can also be used in conjunction with an external scoreboard, such as a separate game board or other physical object. In that case, the �pieces� representing the participants are not moved automatically by the game, but the remaining functions are performed electronically by the game. Other variations and combinations are also possible.
When the game participants have specified that dynamic adjustment of skill levels is desirable, the dynamic challenge level adjuster 103 receives the result of a challenge and determines an adjustment for the participant whose �turn� it is. This adjustment is then typically stored in the participant data 106. The participant data 106 may be stored in a data repository that is the same or separate from the challenge data repository 105.
In step 201, the game determines the number of participants (game players) and other game parameters, such as whether dynamic skill level adjustment is to be utilized and whether initial skill levels are to be determined automatically. In some scenarios, the participants are not given a choice, but instead the game determines the DCLA functionality provided. In step 202, the game determines an initial skill level index for each participant. Again, this can be performed manually or automatically by the DCLA. A routine for determining initial skill level indexes is described with reference to FIG. 3. Eventually, in step 203 (other activity may occur in the interim), when game play is initiated, the game continues in step 204, otherwise returns to one or more of the setup steps, for example, steps 201-202. In step 204, the game determines which participant's turn is next, designates the determined participant as the current participant, and retrieves a corresponding skill level index and score for the current participant. In step 205, the game determines a next challenge for the current participant based upon the retrieved skill level index. Note that, upon subsequent turns for this participant, this index may have been dynamically adjusted by the DCLA to indicate that challenge content should be selected from a different challenge level. In step 206, the game presents the determined challenge to the current participant and obtains a response. In step 207, (assuming that dynamic skill level adjustment has been enabled), the game invokes the DCLA to adjust the skill level index of the current participant and/or a challenge level associated with that participant. A routine for performing these adjustments is described with reference to FIG. 5. In step 208, the game records the score for the current participant and advances the participant on the scoreboard as appropriate. In some embodiments, scoring may be integrated in with the DCLA, such as in games where the DCLA is always operative and automatic skill level adjustment enabled. In step 209, the game determines whether the current participant has won the game (dependent on the game logic, for example, because there may be more than one winner or no winner if the round is incomplete), and, if so, continues in step 210, otherwise continues in step 204 to select start a next participant's turn. In step 210, the game handles any �tie� situations if applicable. In step 211, the game presents winner information, and then ends. In some scenarios, the game may return to step 203 to allow the participants to begin a new game. Also, one skilled in the art will recognize that other and different steps may be provided.
FIG. 4 is an example flow diagram of a routine for automatically determining an initial skill level index for a game participant. An indication of the current participant is designated as an input parameter. The resultant skill level index is returned. The steps illustrated in FIG. 4 are merely exemplary of any number of and type of queries that can be asked of a participant to assist in determining an appropriate initial skill level. It is contemplated that questions even perhaps tailored to the game being played may be presented to gain from the designated participant information that would assist the game in determining an appropriate skill level. One or more of steps 401-404 may be performed as appropriate to the game. For example, in step 401, the routine requests and determines the designated participant's age or other experience determining criteria. Specific inquiries involving year in school (e.g., grade level), countries visited, books read, other games played, are some of the many examples that could be used by the game to automatically determine an initial skill level. In step 402, included in some embodiments, the routine selects a set of sample game content (e.g., challenges), potentially even based upon the answers provided to the questions presented in step 401. In step 403, the routine presents the selected sample challenges and determines the correctness or incorrectness of any responses. In step 404, the routine �rates� the participant according to the answers and responses provided to the previous steps, and assigns a corresponding initial skill level index to the participant (stored, for example, in the participant information data repository 106 of FIG. 1). The routine then returns.
In the example shown in FIG. 5, an indication of the current participant and the participant's response to the most recent presented challenge are designated as input parameters. In step 501, the routine determines whether the designated response was correct or incorrect. The implementation of this step is game dependent and may be handled by the game flow logic. For example, a register or parameter may be used to indicate this information. If the response was correct, then the routine continues in step 503, otherwise continues in step 502. In step 503, the routines makes an appropriate upwards adjustment of the skill level index and stores the value in the participant data as appropriate, and continues in step 504. In step 502, the routines makes an appropriate downwards adjustment of the skill level index and stores the value in the participant data as appropriate, and continues in step 504. Note that the upwards and downwards adjustments may be implemented with opposite logic (e.g., correct answers yielding a downward adjustment) as appropriate to the game, or some other set of heuristics for making adjustments may be used. In addition, adjustments may be made in non-linear increments and/or decrements, and may depend upon the skill level indices of other participants. Many variations are possible. In step 504, the routine determines whether, based upon the newly set skill level index, a change to the challenge level is appropriate, and, if so, continues in step 505, otherwise returns. In step 505, the routine indicates the challenge level that corresponds to the designated participant's new skill level index as the challenge level for the designated participant, and then returns. Dependent upon the implementation, setting or determining a challenge level may be inherent in the skill level index (and not implemented as a separate step) if the mapping between such is handled by the game flow logic (i.e., the game flow logic understands that a participant having a skill level index of �n� maps to a challenge level of �x�),
Although the techniques of automatically determining game content based upon dynamically adjusted individual skill levels and the DCLA are generally applicable to any type of electronic game, the phrases �game,� �game content,� �challenge,� �puzzle,� �question,� etc. are used generally to imply any type of scenario that can be presented to participants to elicit responses that can be scored or represented by a change on a game board. In addition, one skilled in the art will recognize that although the examples described herein often refer to an educational game, the techniques of the present invention can also be used in other environments that would benefit from dynamic content adjustment based upon individual skill levels, such as presenting challenges for certification purposes, testing, etc. In addition, the concepts and techniques described are applicable to all types of platforms that can host or perform such content, including but not limited to personal computers, networked computer systems, computer systems, DVD or DVD-like platforms, handheld gaming consoles, personal digital assistants, etc. Essentially, the concepts and techniques described are applicable to any platform capable of executing the scenarios described herein.
Also, although certain terms are used primarily herein, one skilled in the art will recognize that other terms could be used interchangeably to yield equivalent embodiments and examples. For example, it is well-known that equivalent terms in the multimedia and gaming fields and in other similar fields could be substituted for such terms as �player,� �participant,� �scoreboard,� �audio,� �video,� etc. Also, the phrase �to present� (and its variations) are used to convey an operation appropriate to the content being presented. For example, when audio is presented it is generally played (to be heard), although accessibility-friendly systems may provide other means for presenting audio. Similarly, when video is presented it is generally displayed, although in some system Braille may be used, or an audio interface used to describe the video. In addition, terms may have alternate spellings which may or may not be explicitly mentioned, and one skilled in the art will recognize that all such variations of terms are intended to be included.
Example embodiments described herein provide applications, tools, data structures and other support to implement a DCLA to be used for dynamically adjusting game content based upon individual skill levels. FIG. 6 is an example block diagram of a general purpose computer system for practicing embodiments of an Electronic Gaming Engine including a Dynamic Challenge Level Adjuster. One skilled in the art will understand how to apply the embodiment described herein to other electronic platforms. Typically, such platforms incorporate a memory medium of some nature that is used to hold instructions to cause the game or game engine to be performed. Each portion that comprises the Electronic Gaming Engine (�EGE�) executes on one or more of such computer systems. Moreover, the general purpose computer system 600 may comprise one or more server and/or client and/or peer computing systems and may span distributed locations. In addition, each block shown may represent one or more such blocks as appropriate to a specific embodiment or may be combined with other blocks. Also, the various blocks of the EGE 610 may physically reside on one or more machines, which use standard inter process communication mechanisms to communicate with each other.
In the embodiment shown, computer system 600 comprises a computer memory (�memory�) 601, a display 602, a Central Processing Unit (�CPU�) 603, Input/Output devices 604, and network devices 605. The components of the Electronic Gaming Engine 610 are shown residing in memory 601. (The memory 601 includes any type of computer memory including RAM, ROM, DVDs, CDs, and persistent storage such as disk drives.) The components of the EGE 610 preferably execute on CPU 603 and perform electronic game processing, as described in previous figures. Other downloaded code 630 and potentially other data repositories, such as repository 620, also reside in the memory 601, and preferably execute on one or more CPU's 603. In a typical embodiment, the EGE 610 includes game flow logic 611, game content (challenge) models 612, Dynamic Challenge Level Adjuster (�DCLA�) 613, scoring module(s) 614, challenge data 615, participant data 616, and a game input/output interface 617. One skilled in the art will recognize that many different arrangements of the components of the EGE 610 are possible.
The components of the EGE may be implemented in hardware, software, or some combination of both, using standard well-known techniques, programming languages, hardware, etc. One skilled in the art will recognize that various object-oriented and distributed methodologies may be used. However, any of the EGE components 611-617 may be implemented using more monolithic programming techniques as well. In addition, programming interfaces to the data stored in the challenge data (content) data repository 615, the participant information data repository 616, or the functions of the DCLA 613 can be made available by standard means such as through C, C++, C#, and Java API and through scripting or tag-based languages such as JavaScript or XML, or through web servers supporting such. The data repositories 615 and 616 that are used to store challenge and participant information are preferably implemented for scalability reasons as one or more databases rather than as a text files. However, any method for storing such information may be used. In addition, the DCLA 613 may be implemented as stored procedures, or methods attached to stored �objects,� although other techniques are equally effective.
One particular embodiment of the DCLA has been implemented in a DVD platform and is described in detail in U.S. Provisional Application No. 60/577,446, entitled �DVD Game Architecture.� FIG. 7 is an example block diagram of a DVD system for practicing embodiments of an Electronic Game environment including a Dynamic Challenge Level Adjuster. The DVD system 700 comprises a DVD player 701 connected directly or indirectly to a display device 702. In some embodiments, the DVD player 701 may be optionally controlled by a remote control device 704 or by controls resident or otherwise associated with the DVD player 701. A DVD game, which implements the EGE abstractions, along with instructions for controlling the DVD player to present content and to navigate to other content, are stored on a DVD 703 and played on DVD player 701.
FIG. 8 shows an abstraction of the skill levels available along a continuum 801-803. As implemented in one embodiment, the skill levels range from 0-14, which correspond to three possible groupings of challenge levels: easy, medium, and hard. As shown, skill levels 0-4 are mapped to easy challenges; skill levels 5-9 are mapped to medium challenges; and skill levels 10-14 are mapped to hard challenges. This continuum can be represented in 4 bits of memory and thus a 4-bit value is stored in the general registers for each participant to indicate the participant's current skill level. Note that these mappings and the number of skill levels are modifiable, and that more skill levels are possible based upon what memory tradeoffs are desired. For example, to implement a �hidden� super-easy challenge level, less than 5 skill levels need to be mapped to the other three challenge levels if it is desired to still represent the entire skill level continuum in 4 bits. Alternatively, more bits can be used to represent the continuum thus enabling the same or more skill levels to be mapped to these challenge levels.
When dynamic skill level adjustment has been enabled, a participant's skill level increases for each detected correct answer and decreases for each detected incorrect answer. That way, when the detected correct answers exceed the detected incorrect answers by more than the number of skill levels per challenge level (here, 5 levels), the challenges become more difficult. This adjustment intends to even out the level of play between participants as the game progresses. Skill continuum 801 shows an initial skill level for a game participant. By convention, this initial level is set to a middle value within the challenge level that was initially indicated by the participant or selected automatically by the game. In this example, the easy challenge level corresponds to �cadet;� the medium challenge level to �captain,� and the hard challenge level to �commander.� Skill continuum 802 shows an automatic adjustment of the participant's skill level increased by 3 levels from the initial skill level shown in skill continuum 801. Similarly, skill continuum 803 shows an automatic adjustment of the participant's skill level decreased by 2 levels from the prior adjustment in continuum 802.
