     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0029]    There is disclosed a controller, a joystick, and action buttons for portable electronic devices, including but not limited to the Motorola Droid, Apple iPhone, mp3 players including but not limited to the Apple iPod Touch and Microsoft Zune and, with a larger size which is applicable to the Apple iPad, computer tablets, netbooks and laptop computers. 
         [0030]    Video games played on mobile phones and mobile computers can be awkward and difficult, and when the game play is awkward and difficult, it can deny the player/user of a satisfying experience. Video game players greatly depend on the responsiveness and comfort level the user feels with the control mechanism that interacts with that which is going on in the on-screen video game world. For example, currently a simple movement UP in a video game on a touch screen phone requires the user to swipe or press his or her finger on a specific location such as a virtual joystick on the screen to execute that action. This type of action be a player provides an unsatisfying gaming experience for many users. 
         [0031]    A game controller with a joystick and buttons which are removably attached to the frame around the screen of a computer would solve this problem. Pushing one&#39;s thumb UP on a physical joystick that signals movement along the Y axis which executes a subsequent UP action on the screen in the game would better satisfy the hands-on experience many gamers seek. Working in concert with the joystick, pressing corresponding action buttons will execute jump or fire commands. 
         [0032]    The issue with utilizing a physical game controller for a mobile touch screen device is size limitations. Screens are small and a controller the size of the device is not ideal nor is it practical to carry it around. 
         [0033]    The solution is to removably attach a minimally invasive Bluetooth enabled, rechargeable joystick and corresponding Bluetooth enabled, rechargeable action buttons to the surface of the touch screen device with a removable suction cup or a hook and loop type of removable fastening device such as a Velcro fastener or by magnets. The joystick and action buttons are wired directly to the input source of the mobile device, for example, a USB for a netbook or via a 30 pin connector on an iPhone. The user has the freedom to removably attach the joystick and action buttons any place on the device. For a mobile touch screen device such as a netbook or laptop, attaching the joystick with a removable suction cup and action buttons with a removable suction cup to the lower left and right sides or corners of the screen would be unobtrusive to the on-screen viewing surface and effective in meeting the high standards of today&#39;s mobile gamer. 
         [0034]    Referring to  FIG. 1  there is disclosed a perspective view of the game controller, joystick and action buttons for portable electronic devices with a display where the joystick and the action buttons are removably attached to the screen of a portable electronic device with a display to provide an image of increased size in accordance with the principles of the invention. A controller  12  is coupled through conductive wires to a joystick  14  and action buttons  16 . The Joystick and the action buttons are attached to a portable electronic device with a display with a non-residue, removable micro suction tape, or removable suction cup or a hook and loop type of removable fastening device such as a Velcro fastener or by magnets which are permanently affixed to the bottom of the joystick and the action buttons, The Joystick and action buttons may be located on the lower left and right sides or corners of the portable electronic device with a display  20 . A rechargeable Bluetooth chip and circuitry  18  is coupled to the game controller  12 . Referring to  FIG. 2  there is shown a perspective view of the joystick  14  and action buttons  16  located in the game controller  12 . 
         [0035]    The joystick and action buttons of the controller are removably attached to the surface of a portable electronic device with a display with a non-residue, removable micro suction tape, or removable suction cup, or a hook and loop type of removable fastening device such as a Velcro fastener or by magnets which are permanently affixed to the bottom of the joystick and the action buttons and lock firmly onto the portable electronic device with a display. This allows a user to be up close to the on-screen action, thus allowing for a more visceral experience, and a more user-friendly yet effective means of going about playing a mobile game. 
         [0036]    They are as effective as virtual controls yet provide the user the hands on experience. They are easily and quickly removable to restore other functions of the mobile device. Advantages will become apparent from a study of the following description and accompanying drawing. 
         [0037]      FIG. 1  is a perspective view showing the action buttons  16  on the user&#39;s right side and the joystick  14  on the user&#39;s left side. The oval shaped member  12  represents a storage unit for the controller. The action buttons  16  are mounted on suction cup and the joystick  14  is mounted on a suction cup. A rechargeable Bluetooth chip and circuitry housing  18  is located within the game controller  12 . 
         [0038]    In operation, one uses the controller wired to or wirelessly with the portable electronic device with a display. The user must turn on or plug in the respective joystick and action buttons to activate functionality. For Bluetooth to function properly, as with a Bluetooth headset, it must be paired with the mobile device in order for movement of the joystick and action buttons of the controller to sync navigation of the portable electronic device with a display. 
         [0039]    Paring may be obtained without altering the software or hardware in the controller by coupling the communication port of the portable electronic device with a display to a user interface apparatus which includes a microprocessor that converts instructions from the user interface apparatus to an instruction which is performed by the controller. Thus, while the interface apparatus may be different from both the controller and the interface apparatus in the controller, instructions from the interface apparatus are formatted the same as instruction from the controller. 
         [0040]    While there have been shown and described and pointed out the fundamental novel features of the invention as applied to the preferred embodiments, it will be understood that the foregoing is considered as illustrative only of the principles of the invention and not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments discussed were chosen and described to provide the best illustration of the principles of the invention and its practical application to enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are entitled.
