   DESCRIPTION 
   The present invention relates in general to a gaming device, and more particularly to a gaming device which has moving screen simulation. 
   BACKGROUND OF THE INVENTION 
   Existing gaming machines, such as traditional slot machines, include a variety of game events. Typical events are the player obtaining certain values or awards, the initiation of a bonus round and the termination of a game. Typically when events such as these occur, the gaming machines have certain features which draw attention to the event and entertain the player. For example, if a player advances to a bonus round, gaming machines often flash lights, make sounds or implement other features. Known gaming machines do not simulate movement of the gaming device screen. 
   To increase player enjoyment and excitement, it is desirable to provide players with new features for gaming devices, where the new features involve simulated movement of the gaming device screen. 
   SUMMARY OF THE INVENTION 
   The present invention overcomes the above shortcomings by providing a gaming device which includes a monitor or screen and imagery displayed on the screen. Preferably, the screen is a video monitor. Imagery is the combination of all images displayed on the screen, including background, color and shading. The gaming device also includes a plurality of events, such as the initiation of a primary game or bonus round, the termination of a primary game or bonus round, a player gaining or losing values or a player gaining or losing opportunities. 
   When certain events occur (hereafter, “triggering events”), the computer of the gaming device simulates physical movement of the screen by repositioning the imagery on the screen in order to create the illusion that the screen is physically moving. Triggering events can be any occurrences, predetermined or determined by the computer of the gaming device during a primary game or bonus round. For example, imagery which includes trees on a hillside against a sky blue background would fill an entire screen. By repositioning this imagery, the computer can create the illusion that the screen is physically shaking or moving about in some other manner. The computer can reposition the imagery in a variety of manners. 
   In one embodiment of the present invention, the gaming device includes a plurality of reels, preferably video reels and a plurality of symbols on the reels. Functionally, a plurality of the reels spin, come to a stop and display one or more symbols. One or more reels may not spin and may function solely as a display screen. The term display, as used herein, includes, but is not limited to, showing, performing or otherwise representing a person, place or thing, at rest or in motion, visually and/or audibly. 
   The symbols which are displayed on each reel in relation to each other form a combination of symbols. When a player reaches a predetermined combination of symbols on the set of reels, a triggering event occurs. The computer then initiates a bonus round and displays an initial bonus round screen which includes imagery including objects against a background such as oil derricks against a solid color background. The computer then performs the moving screen feature on this initial screen by iteratively positioning the imagery at various positions. The effect is to simulate actual vibration or shaking of the screen. Preferably, in the oil derrick embodiment, after the simulation stops, the computer displays oil flowing over the initial bonus round screen. Once the oil display terminates, the computer enables the player to play the bonus round. 
   The simulated screen movement of the present invention involves the repositioning of imagery which gives the player the illusion that the gaming device screen is moving. The gaming device can perform this feature upon the occurrence of any triggering event and during a primary game or bonus round. The feature of the present invention provides players with additional excitement and entertainment. 
   It is therefore an object of the present invention to provide a gaming device with moving screen simulation. 
   Other objects, features and advantages of the invention will be apparent from the following detailed disclosure, taken in conjunction with the accompanying sheets of drawings, wherein like numerals refer to like parts, elements, components, steps and processes.

   DETAILED DESCRIPTION OF THE INVENTION 
   Gaming Device and Electronics 
   Referring now to the drawings,  FIG. 1  generally illustrates a gaming device  10  of one embodiment of the present invention, which is preferably a slot machine having the controls, displays and features of a conventional slot machine. Gaming device  10  is constructed so that a player can operate gaming device  10  while standing or sitting. However, it should be appreciated that gaming device  10  can be constructed as a pub-style table-top game (not shown) which a player can operate preferably while sitting. Gaming device  10  can also be implemented as a program code stored in a detachable cartridge for operating a hand-held video game device. Also, gaming device  10  can be implemented as a program code stored on a disk or other memory device which a player can use in a desktop or laptop personal computer or other computerized platform. 
   Gaming device  10  can incorporate any primary game such as slot, poker or keno in addition to any of their bonus triggering events which trigger the bonus scheme of the present invention. The symbols and indicia used on and in gaming device  10  may be in mechanical, electrical or video form. 
   As illustrated in  FIG. 1 , gaming device  10  includes a coin slot  12  and bill acceptor  14  where the player inserts money, coins or tokens. The player can place coins in the coin slot  12  or paper money in the bill acceptor  14 . Other devices could be used for accepting payment such as readers or validators for credit cards or debit cards. When a player inserts money in gaming device  10 , a number of credits corresponding to the amount deposited is shown in a credit display  16 . After depositing the appropriate amount of money, a player can begin the game by pulling arm  18  or pushing play button  20 . Play button  20  can be any play activator used by the player which starts any game or sequence of events in the gaming device  10 . 
   As shown in  FIG. 1 , gaming device  10  also includes a bet display  22  and a bet one button  24 . The player places a bet by pushing the bet one button  24 . The player can increase the bet by one credit each time the player pushes the bet one button  24 . When the player pushes the bet one button  24 , the number of credits shown in the credit display  16  decreases by one, and the number of credits shown in the bet display  22  increases by one. 
   Gaming device  10  also has a display window  28  which contains a plurality of reels  30 , preferably three to five reels in mechanical or video form. Each reel  30  displays a plurality of indicia such as bells, hearts, fruits, numbers, letters, bars or other images which preferably correspond to a theme associated with the gaming device  10 . If the reels  30  are in video form, the gaming device  10  preferably displays the video reels  30  at video monitor or screen  32  instead of at display window  28 . Furthermore, gaming device  10  preferably includes speakers  34  for making sounds or playing music. 
   At any time during the game, a player may “cash out” and thereby receive a number of coins corresponding to the number of remaining credits by pushing a cash out button  26 . When the player “cashes out,” the player receives the coins in a coin payout tray  36 . The gaming device  10  may employ other payout mechanisms such as credit slips redeemable by a cashier or electronically recordable cards which keep track of the player&#39;s credits. 
   With respect to electronics, gaming device  10  preferably includes the electronic configuration generally illustrated in  FIG. 2 , including a processor  38 , a memory device  40  for storing program code or other data, a screen  32  and at least one input device such as play buttons  20 . The processor  38  is preferably a microprocessor or microcontroller-based platform which is capable of displaying images, symbols and other indicia such as images of people, characters, places, things and faces of cards. Screen  32  is a surface on which images are displayed such as a monitor or other display device (i.e., a liquid crystal display). The memory device  40  can include random access memory (RAM)  42  for storing event data or other data generated or used during a particular game. The memory device  40  can also include read only memory (ROM)  44  for storing program code which controls the gaming device  10  so that it plays a particular game in accordance with applicable game rules and pay tables. 
   As illustrated in  FIG. 2 , the player preferably uses play buttons  20  to input signals into gaming device  10 . Furthermore, it is preferable that touch screen  46  and an associated touch screen controller  48  are used instead of a conventional screen  32 . Touch screen  46  and touch screen controller  48  are connected to a video controller  50  and processor  38 . A player can make decisions and input signals into the gaming device  10  by touching touch screen  46  at the appropriate places. As further illustrated in  FIG. 2 , the processor  38  can be connected to coin slot  12  or bill acceptor  14 . The processor  38  can be programmed to require a player to deposit a certain amount of money in order to start the game. 
   It should be appreciated that although a processor  38  and memory device  40  are preferable implementations of the present invention, the present invention can also be implemented using one or more application-specific integrated circuits (ASIC&#39;s) or other hard-wired devices, or using mechanical devices (collectively referred to herein as a “processor”). Furthermore, although the processor  38  and memory device  40  preferably reside on each gaming device  10  unit, it is possible to provide some or all of their functions at a central location such as a network server for communication to a playing station such as over a local area network (LAN), wide area network (WAN), Internet connection, microwave link, and the like. The processor  38  and memory device  40  are generally referred to herein as the “computer.” 
   With reference to  FIGS. 1 and 2 , to operate the gaming device  10 , the player must insert the appropriate amount of money or tokens at coin slot  12  or bill acceptor  14  and then pull the arm  18  or push the play button  20 . The reels  30  will then begin to spin. Eventually, the reels  30  will come to a stop. As long as the player has credits remaining, the player can spin the reels  30  again. Depending upon where the reels  30  stop, the player may or may not win additional credits. 
   In addition to winning credits in this manner, preferably gaming device  10  also gives players the opportunity to win credits in a bonus round. This type of gaming device  10  will include a program which will automatically begin a bonus round preferably when a predetermined combination of indicia appears on a plurality of reels  30 . As illustrated in the three reel slot game shown in  FIG. 1 , the predetermined combination of indicia could be the text “BONUS!” appearing in the same location on three adjacent reels. 
   Moving Screen Simulation 
   Referring now to  FIG. 3 , gaming device  10  displays certain imagery  52  on screen  32 . For purposes of this application, imagery  52  is illustrated by a star and its rectangular-shaped, white background. During a primary game or during a bonus round, when a triggering event occurs, the gaming device  10  displays this imagery  52 . Triggering events are events which occur before, during or after a game or bonus round such as the initiation of a game, the initiation of a bonus round, the player gaining values, the player loosing values, the player gaining opportunities to gain value, the player loosing opportunities to gain value, or the renewal of a game or bonus round. Preferably, when the computer initially displays imagery  52 , portions of the imagery  52  are moving. However, it should be appreciated that the present invention can be adapted so that certain portions of imagery  52  do move. For instance, imagery  52  could include the image of a dog on a hillside, where nothing is moving except for the tail of the dog. 
   In either alternative, the computer displays imagery  52  for a predetermined, relatively short length of time. After this length of time elapses, the computer repositions imagery  52  so as to create the illusion that the physical screen  32  is actually moving. Preferably, the computer accomplishes this simulation by repositioning the entire imagery  52  from position to position in a relatively rapid manner, on screen  32 . 
   Certain reposition techniques are illustrated in  FIGS. 4 through 6 . In these illustrations, the imagery is repositioned from its original position to two new positions. However, the imagery can be repositioned to any number of positions. In  FIG. 4 , the new positions have angular alignments which are different from each other and different from the original position. In  FIG. 5 , the new positions are horizontally displaced to the left and right of the imagery&#39;s original location, and in  FIG. 6 , the new positions are vertically displaced above and below the imagery&#39;s original location. The computer displays the imagery  52  iteratively at these different locations, thereby creating the illusion that screen  32  is physically vibrating or shaking. 
   It should be appreciated that the computer can reposition or otherwise manipulate the imagery  52  in a variety of manners so as to create various screen simulations. For instance, the computer can rotate imagery  52 , shift imagery  52  upwards or downwards or from side to side or combine any of these manipulations. Furthermore, the computer can reposition the imagery  52  to any number of new locations. 
   Eventually the computer stops repositioning the imagery  52 , and the simulation is complete. Following the simulation, the primary game or bonus round may continue, terminate or other events may occur depending upon the particular program of the game or bonus round. 
   In one preferred embodiment of the present invention, the primary game involves a plurality of reels  30 , preferably video reels. The reels  30  display a plurality of symbols. By pushing play button  20 , the player causes the reels  30  to spin. When the reels  30  stop spinning, if a predetermined combination of symbols is displayed, a triggering event occurs and the computer initiates a bonus round. In this preferred embodiment, after the player reaches this triggering event, the computer displays an initial bonus screen-shot. This bonus screen-shot displays certain imagery  52  which is a plurality of oil derricks against a solid color background. 
   Initially, the oil derricks and the background are stationary for a predetermined amount of time. After this time elapses, the computer repositions the oil derricks and background (as a whole) from one position to another on the screen  32  for a predetermined length of time. This process of repositioning creates the illusion that the physical screen  32  is vibrating or shaking. After this simulation is complete, the oil derricks and background become stationary. 
   It is preferable that next, the computer displays liquid oil spilling or flowing onto screen  32 . The computer carries out this visual oil spillage for a predetermined length of time and then replaces this imagery with a third bonus round screen-shot where the computer enables the player to play the bonus round. The player then plays the bonus round until it terminates. Preferably, the imagery and symbols in this embodiment are related to the theme of oil business in the State of Texas of the United States. 
   The simulated screen movement feature of the present invention involves certain imagery which the computer repositions from position to position on a gaming device screen. The rapid repositioning of the imagery creates the illusion that the screen is actually moving (i.e., vibrating, shaking, floating, drifting or rocking). In this manner, the computer simulates physical movement of the screen. This simulation can be included in primary games or bonus rounds of gaming devices. Furthermore, this feature can be used to accompany any event during a primary game or bonus round. The use of this feature adds excitement, entertainment and enjoyment to primary games and bonus rounds of gaming devices. 
   While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but on the contrary is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the claims. It is thus to be understood that modifications and variations in the present invention may be made without departing from the novel aspects of this invention as defined in the claims, and that this application is to be limited only by the scope of the claims.
