     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates generally to controllers for electronic devices. More specifically, the present invention relates to game controllers for hand-held smart devices. 
     Description of the Related Art 
     With a growing number of hand-held electronic devices available to consumers, there is an increasing need for secondary accessories that modify and enhance these devices. Many such accessories exploit existing capabilities of the hand-held devices by enhancing and simplifying a consumer&#39;s ability to use the device. As an example, an accessory may modify a hand-held device so that an attachment provides additional functionalities to the device. As another example, an attachment may enhance a user&#39;s ability to enjoy application software available for the smart devices, such as game applications, by providing additional controls. 
     One of the more recently developed electronic devices are e-readers, tablets, or smart devices having relatively large screens. These smart devices are often used for reading books, internet browsing, watching stored movies, playing games, and other work or recreational activities. Many of these devices, as well as some popular cell phones, and in particular smart phones, have evolved to having a full touch screen and no traditional attachments, such as an alpha-numeric keyboard, joystick, or a game controller. Touch screens also present additional challenges to game users in that the lack of a traditional keyboard, joystick, or a controller generally decreases a user&#39;s ability to react with sufficient comfort, ease, and speed to the demands of a game application. For example, by navigating a game application by means of a touch screen, a user typically utilizes only an index finger of one hand as opposed to traditional game controllers which provide a variety of controls and buttons so that a user may engage one or more fingers of both hands. As another example, controlling a smart device software application, such as a game application, by means of a touch screen may present a problem in that a user may block certain parts of the touch screen while engaging fingers on the touch screen. Thus, a user may be deprived of a higher level of enjoyment of the smart device game and other applications. Further, most smart hand-held devices are not equipped for long-term use in that a user must continuously hold or otherwise prop-up the device. For example, the smart devices themselves are generally planar and need to be propped or angled by hand to view the screen. This can be cumbersome and taxing for extended periods of time and challenging when the user engages in use of a game or other application. Even though many smart devices have the capability to function like a personal computer or another gaming device, most are not designed for such extensive usage. As a result, a number of secondary accessories have been developed to modify the smart devices for enhanced and simplified use such as an attachable keyboard. However, there is a lack of an accessory providing additional controls which a user could utilize for a smart device software applications such as game applications. 
     Game accessories such as game controllers are known in the art. For example, U.S. Pat. No. 6,102,802 discloses a game controller with pressure-sensitive analog sensors for video game machines. U.S. Pat. No. 6,659,870 discloses a game controller with an additional steering lever. U.S. Pat. No. 7,794,326 further discloses a game controller with a variety of controls and pivotal grips ensuring ergonomics of the game controller. The problem is that none of the game controllers are compatible and can be used with the smart hand-held devices such as iPhone®, iPad®, or iPad Mini. 
     Therefore, there remains a need for a game controller accessory for electronic smart devices that provides a user with enhanced ability to utilize and enjoy the smart device application software by offering additional control options besides the touch screen. 
     SUMMARY OF THE INVENTION 
     The present invention addresses one or more of the above needs by providing a controller accessory for hand-held smart devices. One possible embodiment of the present teachings includes: an electronic smart device controller comprising a right side panel, a left side panel, a detachable chassis, and a detachable cradle. The right side panel and the left side panel may receive the detachable chassis or the detachable cradle, such that the detachable chassis can be fastened between the right side panel and the left side panel. The detachable cradle may be fastened between the right side panel and the left side panel, such that the detachable chassis can be completely removed and substituted with a detachable cradle, so that the detachable cradle is substantially planar with a depression portion and serves as a housing for a smart device. The smart device may be inserted into the depression portion of the cradle so that the cradle can support the smart device, and wherein the cradle with the smart device is attached to the right side panel and the left side panel. 
     Another possible embodiment of the present teachings includes: an electronic smart device controller comprising a right side panel, a left side panel and an undetachable cradle. The undetachable cradle may be fastened to the right side panel and the left side panel, such that the undetachable cradle is substantially planar with a depression portion and serves as a housing for a smart device. The smart device may be inserted into the depression portion so that the controller can support the smart device. 
     The teachings herein also provide for a method comprising: providing (i) a right side panel, (ii) a left side panel, and (iii) a detachable chassis and attaching the right side panel to the detachable chassis on the right side of the chassis and attaching the left side panel to the detachable chassis on the left side of the chassis. The method may include detaching the right side panel from the detachable chassis and detaching the left side panel from the detachable chassis. The method may further include providing a right side panel, a left side panel, a smart device, and a detachable cradle having dimensions fit for supporting the smart device, a depression portion to house the smart device, and a raised wall. The method may also include inserting the smart device into the depression portion of the cradle so that it is leaning against the raised wall of the cradle, inserting the cradle with the smart device to the right side panel and the left side panel, and attaching the right side panel and the left side panel to the detachable cradle securely. 
     The present teachings provide a controller that is specifically compatible and fit for one or more smart devices by providing a detachable or undetachable cradle for supporting the one or more smart devices; therefore the user is not limited to controlling the smart device software application with touch screen only. In addition, the controller allows for enhanced enjoyment of the user&#39;s smart device by enabling the user to utilize both hands in controlling the software applications at the same time, therefore increasing the number of control options the user has, the speed and quality of the user&#39;s response to the demands of the software applications, and adding overall flexibility in use and function of the smart device.

     Although the controller described herein includes illustrations relating to its use with an e-reader/tablet style device such as the iPhone®, iPad®, and iPad Mini (available from Apple, Inc., Cupertino, Calif.), it is understood that the controller can be formed in alternative sizes, shapes and configurations to serve as a controller having the described features and utilities for other electronic devices such as smart phones, MP3 players, computing devices, and other popular electronic devices. 
     Any numerical values recited herein include all values from the lower value to the upper value in increments of one unit provided that there is a separation of at least 2 units between any lower value and any higher value. As an example, if it is stated that the amount of a component or a value of a process variable such as, for example, temperature, pressure, time and the like is, for example, from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, it is intended that values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 etc. are expressly enumerated in this specification. For values which are less than one, one unit is considered to be 0.0001, 0.001, 0.01 or 0.1 as appropriate. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest value and the highest value enumerated are to be considered to be expressly stated in this application in a similar manner. 
     Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints. The use of “about” or “approximately” in connection with a range applies to both ends of the range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, inclusive of at least the specified endpoints.
