## Background
FIELD OF THE INVENTION
The present invention relates to an input control apparatus and an interactive system using the same, and more particularly, to an input control apparatus capable of switching between a mouse mode, a joystick mode, a keyboard mode and the combination thereof in a manner that two such input control apparatuses can be integrated as a handheld device with a left-hand unit and a right-hand unit while both connecting to an electronic device, such as a computer, an interactive gaming device or an interactive multimedia device and thus forming an interactive system.
BACKGROUND OF THE INVENTION
After developing for years on the high gear, multimedia game enjoys great breakthrough not only in its audio and graphic performances, but also in it animation capability, since the computation abilities of electronic devices relating to multimedia games had been greatly improved which is directly resulted from the recent rapid development of semiconductor industry. Hence, players can now enjoys a multimedia game in a virtual-reality environment full of sounds and images.
Although the fun of playing multimedia games can be greatly enhancing by the improvement of audio/video effect, it is noted that for most multimedia games, conventional input interface, such as keyboard, joystick, or mouse, etc., are still used by players as the control device. In another word, as players can only interact with multimedia games through such conventional handheld input interfaces, the fun of playing multimedia games is reduced.
There are already some techniques for improving such disadvantage. One such technique is a game controller disclosed in U.S. Pub. No. 20070050597, entitled “Game controller and game system”. The aforesaid game controller is comprised of: a master control unit; and an auxiliary control unit; wherein the master control unit has more operation buttons that the auxiliary control unit. Moreover, the master control unit can be operated independently in a manner similar to a common remote control, while the auxiliary control unit is only operable when it is electrically connected to the master control unit by a transmission wire and is only used for controlling the movement of a cursor displayed on a game screen. Thus, the aforesaid game controller is short in that: it is unable for the auxiliary control unit to function independently without connecting to the master control unit, and further, the game controller lacks the ability to integrate functions of various input interfaces, such as mouse, keyboard, joystick, etc., into the game controller.
Another such technique is disclosed in U.S. Pat. No. 6,782,245, entitled “Wireless peripheral interface with universal serial bus port”. The wireless peripheral interface is used for coupling with a Universal Serial Bus (USB) port for connecting a wireless peripheral with a host computer or controller. Wireless peripheral devices (e.g., keyboard, mouse, trackball, touch pad, joysticks, and game controllers) transmit communication signals to the peripheral interface, which are received and processed into formats suitable for transmission to the host computer or controller via USB. However, the aforesaid interface is still short in that: conventional input devices (e.g., keyboard, mouse, trackball, touch pad, joysticks, and game controllers) are still used as control device for the host computer that the aforesaid wireless peripheral interface lack the ability to integrate all those device coupled to such wireless peripheral interface into one single control device; and thus a game executed on the host computer is played by those conventional mouse, keyboard or joystick that is dull and not lively enough.
Therefore, an inertial sensing input control apparatus is needed for providing users with an integrated operation interface to interact with an electronic device connected thereto.

As methods for charging the inertial sensing input control apparatus 100 are known to those skilled in the art, and thus are not described further herein.
Please refer to FIG. 2, which is a schematic block diagram depicting the interactive system of the first exemplary embodiment. The inertial sensing input control apparatus 100 comprises an inertial sensing module 109, a switch unit 110, a remote control unit 111 and an interface unit 112. The inertial sensing module 109, being configured with at least an inertial sensor, is used for sensing at least a control motion and thus correspondingly generating at least an inertial sensing parameter. It is noted that each inertial sensor can be a device selected from the group consisting of a gyroscope, an accelerometer, and the combination thereof. AS the inertial sensor is designed to detect the limb movements of a user, other than inside the inertial sensing module 109, each of which can be attached to a specific location of the user's body, such as the abdomen, the front arm, the leg, and so on, but is not limited thereby. In addition, the inertial sensing module 109 can either be arranged inside the inertial sensing input control apparatus 100, or outside the inertial sensing input control apparatus 100, whichever is electrically connected with the inertial sensing input control apparatus 100 by a wired manner or wireless manner.
In FIG. 2, the interface unit 112, used for generating at least an input signal, is electrically connected to the plural press-keys arranged on a surface of the inertial sensing input control apparatus 100 of FIG. 1, so that when any one key or any key combination is pressed, the interface unit 112 will receiving a signal corresponding to the key-pressing and then transmitting the signal to the remote control unit 111. Moreover, the switch unit 110 is electrically connected to the mode switch key 1051 of FIG. 1 so as to be used for selecting an input mode for the inertial sensing input control apparatus 100, in which the input mode is a mode selected from the group consisting of a mouse mode, a joystick mode, a keyboard mode and the combination thereof, but is not limited thereby.
The aforesaid input mode is defined with respect to the I/O protocol of different input interfaces. Taking the embodiment of FIG. 1 for example, as the keyboard 303 is used as the input unit of the electronic device 300, so that the computer 301 must be equipped with the I/O protocol for such keyboard. The remote control unit 111 is coupled to the inertial sensing module 109, the interface unit 112 and the switch unit 110 for enabling the remote control unit 111 to generate and thus transmit a control signal to the receiving end 200 according to the I/O protocol of the selected input mode, the at least one input signal and the at least one inertial sensing parameter.

AS shown in FIG. 2, the receiving end 200 comprises a receiving unit 201, an operation unit 202 and an interface connecting unit 203. The receiving unit 201 is used for receiving a control signal generated from the remote control unit and thus decoding the control signal into an inertial sensing parameter, at least an input signal and at least an I/O protocol. The operation unit 202 is coupled to the receiving unit 201 for analyzing the inertial sensing parameter into at least a motion signal while generating an operation signal according to the at least one input signal and the at least one I/O protocol. The interface connecting unit 203 is used for transmitting the operation signal and the at least one motion signal to the electronic device 300. Moreover, the communication between the interface connecting unit 203 and the electronic device 300 can be realized in a wired or wireless manner, in which the wireless communication can be enabled by Bluetooth or radio frequency communication, such as radio frequency identification (RFID) means; as the wired communication can be enabled by the use of an universal serial bus (USB) port, or other connection port, such as RS232 or SCSI, but is not limited thereby.
The communication between the inertial sensing input control apparatus and the receiving end is illustrated in FIG. 1 and FIG. 2. For instance, when a user playing a multimedia game or an interactive software on the interactive system 400 of FIG. 1, the inertial sensing input control apparatus 100 which can be held in one hand of the user is enabled to detect the movement of the hand by the inertial sensing module 109 configured therein and thus generate an inertial sensing parameter accordingly. In addition, during the proceeding of the multimedia game or interactive software, the user can enhance his/her interaction with the game and the user by the use of those press-keys formed on the inertial sensing input control apparatus 100, such as cross key 102, the key A 104 or the key B 106.
Furthermore, also during the proceeding of the multimedia game or interactive software, the user can use the mode selection key 1051 for directing the switch unit 110 to select an input mode for the inertial sensing input control apparatus 100. That is, the switch unit 110 is going to perform an evaluation to determine values of a mouse input flag, a joystick input flag and a keyboard input flag so as to select an input mode according to those flag values. Please refer to FIG. 3, which shows an input mode selection of the present invention. In an exemplary embodiment shown in FIG. 3, a plurality of input modes are defined with respected to different flag value combinations, that is, by assigning the aforesaid flags to be either 1 or 0, an input mode can be selected and used for transmitting data to the electronic device 300. For instance, when the mouse input flag is 0 while the joystick and keyboard input flags are both 1, the joystick+keyboard mode will be selected.
In the exemplary embodiment of FIG. 1 and FIG. 2, the mouse mode is selected for illustration. Please refer to FIG. 4, which is a schematic diagram illustrating how an input control apparatus of the invention is configured to imitate a computer mouse when the mouse mode of the input control apparatus is selected. As shown in FIG. 4, the inertial sensing input control apparatus 100 will mimic a computer mouse to interact with the electronic device 300. For instance, when the left key 1052 of the inertial sensing input control apparatus 100 is pressed, the electronic device 300 will respond just like the left key of a mouse is pressed, and that is the same to the middle key 1053 and the right key 1054. Moreover, when the inertial sensing input control apparatus 100 is moved, the cursor displayed in the display unit 302 of the electronic device 300 is going to move accordingly.
FIG. 5 is a schematic diagram illustrating how an input control apparatus of the invention is configured to imitate a keyboard when the keyboard mode of the input control apparatus is selected; and FIG. 6 is a schematic diagram illustrating how an input control apparatus of the invention is configured to imitate a joystick when the joystick mode of the input control apparatus is selected. As shown in FIG. 6, the inertial sensing input control apparatus 100 in such joystick mode can assign its press-keys and motions detected by the inertial sensing module thereof to correspond to different keys of a joystick. Similarly, as shown in FIG. 5, the inertial sensing input control apparatus 100 in such keyboard mode can assign various inertial sensing parameters to various motions detected by the inertial sensing module thereof and thus further to correspond to different keys of a keyboard.
Please refer to FIG. 7, which shows an interactive system according to a second embodiment of the invention. Different from the first embodiment shown in FIG. 2, the interactive system has two inertial sensing input control apparatus 100 that are electrically connected with each other while each is capable of transmitting a control signal to the receiving end 200 through its remote control unit 111. As each inertial sensing input control apparatus 100 is equipped with its own switch unit 110, the two inertial sensing input control apparatus 100 can defined their respective interface units 112 to operate under different input modes. For instance, the two such input control apparatuses 100 can be integrated and acted as a left-hand unit and a right-hand unit of an integrated a handheld apparatus for meeting the control requirements of a comparatively more complicated game executing on the electronic device 300. In addition, the input control apparatuses 100 can be configured as independent devices to be operated by different users so that the number of the input control apparatuses is not limited to be two, and thus can be as many as the electronic device permitted.
To sum up, the inertial sensing input control apparatus is a device capable of imitating functions of various input devices, by which a user playing the interactive system will not need to shift between different input devices just for meeting different control requirements of the interaction. In addition, the inertial sensing input control apparatus is configured with an inertial sensing module for generating inertial sensing parameters corresponding to the motion of the input control apparatus, which can be configured to conform with various I/O protocols in respective, and thus enables the electronic device to act corresponding to those I/O protocols as soon as the receiving end receive such inertial sensing parameters. Moreover, a plurality of such inertial sensing input control apparatuses can be connected with each for meeting the control requirements of a comparatively more complicated game executing on the electronic device, or the control requirements of game required to be played by both hands.
The invention being thus described, it will be obvious that the same may be varied in many ways.
