SYSTEM AND PROCESS FOR INTERACTIVE SIMULATION AND FOR DISSUADING YOUNG PEOPLE FROM TAKING DRUGS

Abstract: A system and method is disclosed for interactively simulating and discouraging drug taking behavior, in which a simulated ingestion of drugs provides an initial enhanced sensation of movement and sound, and apparent enhanced player performance. After a determined time, the effect wears off, the player must take time to obtain and take another dose. The scenario is repeated, but with each repetition, tolerance to the drug grows, the "highs" are shorter, and a growing percentage of the player's time must be devoted to obtaining and taking the drugs. A series of repetitions turns initial elation into frustration and strongly discourages drug use. The invention is illustrated by an implementation in the form of a modified multimedia motorcycle racing game.

Description: This invention generally relates to the field of cognitive modification, and more particularly to the utilization of technological means for simulating the deleterious effects of drug usage and thereby discouraging the use of drugs by youngsters. BACKGROUNG OF THE INVENTION Use of addictive drugs by young people is a tremendous and tragic problem worldwide. Current approaches to this problem include international, military and police efforts to control the production and interdict the flow of addictive drugs, as well as a diverse array of programs involving education and role models that are designed to deter youngsters from using drugs. The present invention focuses on the "user side" of the problem. However, rather than using conventional passive media such as stories, books, or videos, the present invention seeks to employ more active delivery methods in order to increase the power and effectiveness of the anti-drug message. It is well established that interactive video, arcade, handheld and multimedia computer games capture the attention of young people as do few other toys. It occurred to me that it might be possible to use these particular interactive media, combined with the information I have gathered professionally regarding the patterns of drug use and addiction, to create for youngsters a strong and lasting predisposition against ever getting involved with drugs. Drug taking is characterized by an initial "high", followed by a depressed state as the drug wears off. Repeated ingestion results in "tolerance", that is, less of a high for a given dose, a shorter high, and ever deepening states of depression that follow. Considerable anxiety and preoccupation surround the expensive process of securing another dose. Increasing the dosage can temporarily counteract the development of tolerance, but the subsequent bouts of depression will typically deepen. Further, in increasing the dosage (or dealing with drugs of unknown strength) is very easy to self-administer an overdose, which can readily kill. With some drugs, there are strong withdrawal effects when an established habit cannot be sustained. Obviously, drugs constitute a "disaster area" for our youth, and major ongoing threat to society. US-A-5 035 625 discloses a method of teaching a student via a computer game combined with a teaching system. The game, such as e.g. a football game, is interrupted at pause points and the student is asked questions such as e.g. math questions. If the student answers correctly the probability for higher scores in the game playing session afterwards is increased, e.g. the joystick is sampled more often than regular and thus the mobility increases, and, conversely, the probability for higher scores later on is decreased if the given answers were wrong. SUMMARY OF THE INVENTION It is an object of the present invention to harness the most powerful interactive media available in order to deliver a compelling and lasting anti-drug message to young people. Further objects of the invention include the following: to provide a simulated experience of actually making a decision whether or not to take a dose of drugs, and then to demonstrate the effects of that decision. to provide a system that may be used at any time of the day or week and is not limited to certain physical or psychological sessions. to provide a versatile system that can be used alone; can be used to provide "booster" sessions for renewed impact or to reinforce other treatments; can be used to deter use by pleople who have never used drugs; or can be used to treat people who have been addicted. to provide specific implementations of the invention in a variety of embodiments, so as to have the option of obtaining reinforcement either by readministering the original embodiment, or by administering different embodiments, over a period of time. to provide different and alternative implementations that target different drugs. to encourage situations wherein a subject who has used the invention and its simulated option to take drugs, will suggest to another subject not to use the simulated drug option. The objects of the invention are achieved through multimedia electronic games that may be adapted to run in a variety of forms on any of a number of state-of-the-art gaming platforms. In such a game, a simulated ingestion of drugs provides an initial enhanced sensation of movement and sound, and apparent enhanced player performance. After a determined time, the effect wears off, the player has to attend to the preoccupations of taking another dose. The scenario is repeated, but with each repetition tolerance to the drug grows, the "highs" are shorter lived, and growing percentage of the player's time must be devoted to obtaining and taking the drugs. After a series of repetitions it becomes clear that rather than enhancing the player's ability to play the game, the drug taking has become a serious limitation that completely frustrates any concerted effort to play the game competitively. As shown in the description that follows, and in the accompanying drawings, the invention has been implemented in the form of a motorcycle racing game on a "multimedia PC" platform. However, as further explained in such description, the principles of the invention could equally well be implemented in any of a variety of electronic games that pit the user's skill against the computer, or indeed against other users, and on any of a variety of gaming platforms.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Typical Operation of the Invention Figure 1 is a flow chart showing the typical mode of operation of the invention in the context of an interactive electronic game. It is important to recognize that the principles of the invention, as illustrated in Figure 1, could be implemented in an unlimited number of completely different interactive game programs, and furthermore, that such principles are not specific to any particular additive drug. Indeed, the flowchart in Figure 1 itself represents a specific embodiment in which certain design decisions not dictated by the principles of the invention have been made, as a matter of arbitrary choice or for ease of illustration. Figure 1, therefore, should not be understood as defining the limits of the invention. In Figure 1 , the program begins in a "Start" state, 101 . General initialization 103 as appropriate for the type of game involved then follows. Either following step 103 (as shown here for clarity) or as part of step 103 , certain performance parameters for the game are set to default or base levels, 105 . The user is then presented with a choice 107 to take or not to take a simulated dose of drugs. If the user chooses not to take the drugs, conventional game play 109 follows. If the user opts to take the drugs, a further series of initialization steps ( 111 to 117 ) follows. An initial drug level is set, 111 . A timer is started, 113 . The selected performance parameters are "enhanced" - that is, increased or decreased in order to give the user apparently superior performance characteristics, or to give inferior characteristics to game opponents and/or antagonists. Background effects (music, etc.) are started, 117 (a normal initialization step which has been delayed). The game then enters an event loop, shown here as an event polling step 115 . On each "timer tick" 121 the drug level is examined and possibly reduced by a certain amount 123 , and the performance parameters are optionally adjusted 125 in accordance with the new drug level. Default timer processing 127 handles the normal processing that must occur on every timer tick in a game of the type involved. (Other normal processing, such as processing of user input control events, is assumed but not shown). The game may define "special events", such as collisions, fight sequences, etc., which are to be handled, for example, more benignly than normal, in order to augment the perception of enhanced performance. Such special events are detected 129 and processed as desired 131 . Finally, when the drug level has been sufficiently reduced by repetitions of step 123 , a "drugs worn off" condition arises, which is detected in step 133. If step 133 detects that the drugs have worn off, a cycle of steps 135-143 are performed before game play is continued. First, the player slows down and/or stops (shown here as a sudden stop) 135 ; performance parameters, if still enhanced, are disenhanced, and background events are suspended. The user is then presented with a decision whether or not to take another dose of drugs 137 . In this example, the only way for the user to proceed with the game is to take another dose. A "Yes" response results in a full or partial restoration of the drug level 139 , corresponding adjustment of parameters 141 , resumption of background effects 143 , and resumption of play in the event loop 115 . The foregoing illustrates the characteristics of a typical game that incorporates the principles of the invention. Variations and extensions of the modes of operation shown will be obvious, with respect to game implementation, to those skilled in the art of electronic game implementation, and with respect to game design, to those versed in the pharmacology of addictive drugs. Operation of a Working Version of the Invention - A Modified Motorcycle Racing Game As previously stated, the invention as illustrated in Figure 1 can be implemented in an unlimited number of interactive games, with the mode of the interaction being based on a variety of addictive substances. The example chosen by the inventor for purposes of demonstration is based on a motorcycle racing game, and is targeted at the drug cocaine. This example has been implemented to the point of an operable working prototype. It is a modification of an existing popular multimedia motorcycle racing game, "Cyclemania", by Compro Software Systems Ltd. of Israel. Copies of the unmodified game are available through ordinary entertainment software distribution channels. The modification provides an option at the start of the game to play in either conventional mode, without drugs, or to play in a different mode, with cocaine. Cyclemania is a circa 1994 game, and the demonstration was created on a limited budget. While it illustrates the principles of the invention, and is the preferred embodiment at this time, obviously much more could be done on the more powerful platforms and software environments that exist as of the date of this patent application. Such platform include poserful dedicated arcade machines, virtual reality consoles with head mounted displays, the Nintendo 64, Sony Playstation and Sega Saturn videogame systems, personal computers based on Intel or other CPU chips, as well as networked computers running distributed interactive game applications. The preferred embodiment runs on modest PC equipment. A minimal setup requires a 486-66 or faster processor, 8 MB or more of RAM, a SoundBlaster or other recognized sound card and a 2X or better CD ROM drive. The details of the preferred embodiment in no way limit the invention or the attached claims. Figure 2 illustrates a typical computer setup for playing multimedia games of the "arcade/action" variety. It comprises a CPU 201, video monitor 250, high speed (2X or better) CD drive 210, joystick 240 , keyboard 230, stereo sepakers 260, 265, and optionally a mouse 220. The video monitor 250 is shown in Figure 2 displaying a typical scene from a conventional (non-drug) playing session with the Cyclemania game. Figure 3 is a "screen shot" (a printout of a captured full-screen image from video monitor 250 ) of the first screen of the modified Cyclemania game that appears after the opening credits and initialization. The background display 310 is the same as in the unmodified game. Overlayed on this display is a dialog box 320 that automatically appears which presents the keyboard selectable choice 330 , 340 to play a conventional game "without drugs", or to play "with cocaine", using keyboard function keys "F1" or "F2". The figures also show the motorcycle instrument panel 350 (with analog, metric speedometer 351 , tachometer and gearshift indicator 352 and gas gauge 353 ), overlayed position and lap indicators 311 - 314 and timer 315 , showing elapsed time in the game. Partially obscured by the dialog box in this figure is a digital "miles per hour" speed display 316 at top center (in addition to the analog, metric speedometer 351 ). The player's start position is fixed as the third of six riders. A Walkthrough of a Conventional Play Session Figure 4 shows the start of a conventional game. As is typical in games of this genre, the program designers have gone to great lengths to provide for realism in vehicle physics and game play. This particular game is notable for the realism of the scenery and the accompanying 3D terrain generation, providing (without drugs) a breathtaking simulated ride through actual roads in Israel. The user must acquire considerable skill to turn in a competitive performance in the conventional game. Figura 4 shows that at the start of the game an additional status panel 411 becomes visible showing where the player 420 (initially pointed out by arrow 421 ) stands in relation to the five other riders in the race. One second into the game, as shown in timer 315 , the player has already fallen to last place, just trying to get the bike moving. The bike quickly accelerates to speeds, upwards of 150 m.p.h. However, turns must be carefully executed at this speed, or the bike will wipe out with disastrous consequences. Figure 5 shows the immediate aftermath of such a wipeout (biker 511 and bike 512 flat on the ground). It is possible in the conventional game to start catching up on the group. Figure 6 shows the player 611 having advanced to third place, attempting to overtake the second place bike 612. However, a slight collision between two bikes flattens our player again, which in the virtual world only results in sending him or her to last place. Trying once again to catch the others, the player, 711 in Figure 7, comes up on a "slow moving" Porsche® 712. Not surprisingly, as shown in Figure 8, not going around the slower vehicle, results in a crash 811, again sending the player back to last place. Despite such potential setbacks, with effort and learning, the conventional game can be mastered and won. Description of Game Play "With Cocaine" The present invention is illustrated when the user, presented with the innocent looking choice in Figure 3 , selects, via the keyboard, the simulated option 340 to take cocaine. The player's computer character then says "Whoa, what a rush!" and the modified game begins. Figure 9 shows the start of the modified game. This scene is similar to Figure 4 of the conventional game, except that gauge 353 in Figure 4 has been replaced in Figure 9 by a head-shaped bar-graph 953 . This bar graph serves as a form of "drug-o-meter" showing how much drugs remain in the player's "head". The bar is rendered in color, with red at the bottom and changing to amber in the middle, and yellow at the top. When the "cocaine" option is selected at the beginning of the modified game, and whenever the user "refills" with the drug during the course of play, the bar graph moves from empty to full in an animated sequence over approximately two seconds, giving the visual effect of filling one's head with a "snort" of cocaine. A hissing sound effect is provided for accompaniment. After this brief interlude, the game begins. The clock begins to roll, but - unlike the conventional game - the other bikes will not start moving until the player's bike is underway. The user here gets off to a reasonable start in fourth place (tied for third according to panel 911 ). Once all the bikes blast away, the player weaves through all of them almost immediately and surges into first place, winding the bike up to about 170 m.p.h. ( Figure 10 ). The bike will not fall over in turns, leaps over overtaken and oncoming traffic and obstacles (including opponent's bikes, pedestrians, horses, etc.), and is essentially unstoppable. However, as shown in the "head" indicator 1053 , the drug inevitably wears off. Clock 1015 in Figure 10 shows the situation 23 seconds into the game. The player surges along in first place for about another five seconds, and then completely runs out of drugs at about 30 seconds. This is evidently unbearable, for the player slams on the brakes, decelerates from 170 to 0 m.p.h. in a handful of seconds, and at about 35 seconds on clock 1115 comes to a full stop at the side of the road as shown in Figure 11 . There is only one thing on his or her mind: a dialog 1160 appears in the form of a "though bubble", saying "I want another dose!". As shown in panel 1111, the closest rider behind has already blasted by. Getting antoher dose is not really an "option" in this embodiment. It is a necessity. The player can't answer "no" to this question. The only way out (short of flipping the power switch) is to hit the escape key, thereby bringing up the option to quit, resume, or start a new game. There is no way to continue the modified game, once started, without continuing to take drugs. Hitting the Return (Enter) key gets the player the needed dose. By the time the player finishes snorting up, all of the other bikes have zoomed by. The player, with some effort, can get back into a reasonable position. But it starts to get harder with each iteration, as the duration of the "high" from the dose of cocaine gradually tails off over repeated doses from the initial duration of 30 seconds on the game clock down to the 10 to 12 second range. Figure 12 shows a situation 1:14 minutes into a game, after one "refill". The player 1220 is closing in on the third-place rider 1212 . However, the indicator 1253 shows that the player has just run out of drugs. Instead of overtaking rider 1212 , player 1220 hits the brakes and comes to a screeching halt as shown in Figure 13 , demanding "another dose". A mere seven seconds after Figure 12 , as shown by clock 1315 , the player is back in last place. By the time he/she refills, the player will be well back in last place, facing ever diminishing effects from the given dose of drugs. The result is that, despite the seeming enhancement in his/her performance, the player falls steadily behind, and it becomes completely impossible, because of the recurring, debilitating obsession with having to get another dose, ever to catch up with the other racers. How Does it Work? Programming the modifications shown here involved overlaying some simple graphics (the "head" bar graph) on the screens of the existing game, continually outputting the "head" status from within the game's "event loop", manipulating a number of control variables, and providing a few substitute high-level program routines. In Cyclemania, as in the typical action/arcade game, a large number of internal program variables are "exposed" at or near the surface of the user interface. This is to enable programming with relatively high level scripts, as well as to control game play attributes for purposes of testing, debugging and review. A typical situation in which similar variables are altered, albeit for entirely different reasons, are to provide "cheat codes" and "God modes" in these types of games (sometimes put in to help the testers and then left in (but not publicized) for "fun" and future development). Cyclemania has a full complement of these exposed internal variables. In combination with some very simple source code modifications (the control sequences for the opening screen and "I Want Another Dose" dialogs), these variables can be easily utilized to accomplish the unique requirements of the invention. Figure 14 is a flow chart showing the operation of the substitute and additional routines incorporated in the modified Cyclemania game in order to implement the invention. Briefly, in conventional Cyclemania there is a base range of performance parameters including parameters such as player speed, opponent speed, aggressiveness, responsiveness to user inputs, sound volume and tempo, and the like. At the very beginning of the game, an extension 1407 - 1419 to the program's initialization routine 1405 sets up the opening drugs/no drugs dialog, and operates the animated "head" graphic and sets the timer for the first time. When the user elects at the beginning of game play to take cocaine 1410 , the modified program simulates a drug induced state by enhancing those parameters above their base range, reducing the speed of opponents, setting the gas level to "full" and disabling the decrementation of the varialbe indicating gas consumption 1412-1419 . In addition, three substitute routines are provided (at 1460 ) to execute in lieu of the ordinary collision routine. First, where the collision is with another rider, the substitute routine 1462 , instead of causing a fall, causes the player's bike to scoot around the other bike (without any user steering input, and even if the evasive motion implies impossible G-forces). If the collision is with any other type of on-road object, then, no matter how big or high this object is, or how fast it is moving, or what direction it is moving in, a second substitute routine 1464 is invoked to cause the player's bike to jump over it (thereby defying gravity). (Thus, the rider on cocaine can cruise at 170 m.p.h. down the wrong side of the road straight into the radiator of an oncoming semi-trailer truck and the program will lift the bike over the truck, allowing our player to continue on his or her way at undiminished speed). Where the collision is with the side of the road (or the scenery), a third substitute routine 1466 simply tracks the bike along the edge of the road at its current speed, without regard for user input or G-forces. The main action in the game is called from the event loop 1430 , which begins upon the completio of initialization. The event loop is a continuous loop which polls for defined events and processes them until there occurs an event that forces termination of the loop. The events to be processed include a number that are processed in a conventional game, and in some cases these events are processed in the same manner as in the conventional game. Conventionally handled elements include default timer processing 1444 (based on "ticks" form the system clock); default input processing 1452 (although with altered sensitivity and acceleration parameters); graphics generation 1456, 1457 and rendering 1458 during "vertical retrace" of the video display 1455; reloading terrain data from the CD 1470, 1471; and sound events 1475 , 1477 . However, in the version of the game with drugs, "timer tick" processing 1440 , in addition to the normal default processing 1444 , also affects the drug level. After a dose of cocaine has been given, the dose will reduce to zero over some determined (but diminishing) amount of time, as a result of decrementing at step 1442 in response to a timer tick event 1440 . The running out of this timer triggers an "out of cocaine" event 1480 . The occurrence of this event does not affect the opposing riders (except that they resume their normal speed) or stop the clock, but causes routines to be executed to do the following: 1. Decelerate the player's bike to a stop; set opponents back to normal speed 1481 - 1484 . 2. Raise the "I want another dose" dialog and wait for as long as required for an affirmative press of the "Enter" key or an "Escape" 1485 - 1487 . 3. Fill the animated "head" bar graph graphic 1489-1492. 4. Reset opponents to reduced speed 1493 . 5. Continue (letting the player restar his/her bike) 1494 - 1497 . Each time the player takes a dose of drugs, the initial value (DLINIT) of the decrement counter that specifies the number of system clock ticks until the current dose runs out, is reduced by 25% until the duration of the cocaine high has been shortened to its minimun of 10 seconds 1489-1491. The routine that reduces the "head" bar display while the player is riding is a substitute for the normal routine that operates the gas gauge. The original gas routine is not used in the modified version, and in any event, in the modified version, the gas gauge display has been overlayed by the "head graphic". The substitute routine works the same way as the normal gas gauge report, except the "head" indicator is a pure function of time determined completely by the initial setting of a decrement variable and timer ticks 1440 in the program's event loop 1430. Options for Further Refinement and Development There are numerous options for potential variation or embellishment over the present embodiment. For example, the ability to increase or calibrate the dosage could be provided, providing a temporary boost, further deepened depression, and the possibility of sudden death through an overdose. Randomness could be incoporated, affecting parameters such as the strength of a batch of drugs (also with the possibility of overdose). A multiplayer game could be provided, where players "on drugs" could compete against others (and/or additional computer-controlled players) playing conventionally. Other games besides motorcycle racing games will be utilized, as the objects of the invention are best achieved if a variety of games are available. Other implementations could include any genre of interactive game that pits the skill or dexterity of the user against the computer and/or other players, Examples include other forms of racing games, other "action" games such as "shooter" games, fighting games, and sports games, among others, as well as simulations, adventure and role playing games. Any of such games could be implemented on any of the arcade, virtual reality, videogame or computers systems discussed herein or on any future game playing platforms. In addition, other drugs could be modeled. In the context of the present motorcycle racing game, possible examples include the following: Opiates (heroin): "With heroin (F2) or without drugs (F1)". If F2 is selected a sound of aspiration is played indicating that the racer is snorting or "chasing the dragon". The displayed yead that indicates drug level in the body gets full. All the players start racing except the stoned one who says "Whoa, what a rush" (or something of the kind), bends his head and does not move. When the level of the head has decreased a fourth, then he is ready to run in the same conditions of the cocaine option of the test trial: jumping over other cars, not falling, etc. This cycle is repeated as in the cocaine option. If F1 is selected a normal race takes place. Alcohol: "With alcohol (F2) or without drugs (F1)". If F2 is selected, the screen gets blurred and the rest takes place in the same manner as with the cocaine option. The only difference is that with alcohol, crashes take place as in the normal option and he takes a bit longer to recover from them. In summary, after an initial representation of the differential "behavioral and/or subjective" effects of drugs (i.e., cocaine = excitement, heroin = drowsiness, alcohol =blurred vision), the well being and sense of power that these drugs offer are similar ("what a rush", speed, etc.). These and other different effects of each drug could also be represented depending on the type of game or action, the potential "personality" of the player, the dosage of the drug taken or a combination of these variables. For instance, in a game with two possible levels of cocaine intake, the larger dose would "paralyze the player" and with the lower dose the player would behave as we see in the present game. More complex physiological sounds or effects can be added, so that the player will have a deeper knowledge of the internal effects of the drug. For instance, heart rate could also be displayed. In the case of cocaine, heart rate would be higher at the beginning of the drug intake and slowly decrease in parallel with the decrease of drug level head marker, giving a more realistic effect to the experience of playing "stoned". While discussed above in the context of the example motorcycle racing game, using similar techniques, those skilled in the art could readily simulate the effects of different drugs in the differente modes or versions of any game constructed in accordance with the principles of this invention. It is apparent from the foregoing that a new system and method have been developed which demonstrate the great power of interactive game media to deliver a compelling anti-drug message to youngsters. It is my hope that this invention will be successfully used to keep kids from ever using drugs. While the presently existing implementation has been described in greatest detail, it will be apparent to those skilled in the art that up-to-the-minute interactive games and media could be substituted, and the order of play and interaction varied, without departing from the scope of the invention, as defined in the following claims.
