`
`DETAILED DESCRIPTION OF PREFERRED
`EMBODIMENTS
`
`In order to work with computer peripheral device, the
`design of PC gamesat early stage mostly used a keyboard or
`mouse as the input source; therefore, a keyboard motion
`mapping table is designed by software programming in each
`PC game,
`in which the keyboard motion mapping table
`records the correspondence between each motion command
`of the PC gameand any key command on a keyboard. The
`purposeofthe keyboard motion mappingtable is to allow the
`PC gameto be ableto resolve the motion commandissued by
`the user through a specific key, and then, using the keyboard
`motion mappingtable, to facilitate execution of correspond-
`ing motions to the PC game. For example, jump up motionis
`represented by the Up key (1) on the keyboard, jump down
`motion indicated by the Down key (|), forward motion by the
`Left key (<-) and backward motion by the Right key (=).
`However,as the drawbacks caused by the keyboard motion
`mappingtable in the priorart set forth hereinbefore, this may
`largely weakenthe entertaining effect created by existing PC
`games. Besides, since people’s demands may increase and
`health-care issues may becomenoticeable in the future, long-
`term use ofthe PC game employingexisting keyboard motion
`mapping table by the user can result in specific injuries to
`user’s body(e.g. fingers), so conventional PC gamesusing the
`keyboard motion mappingtable will inevitably vanish on the
`market gradually.
`In orderto allow existing popular PC gamesto survive on
`the current market, the present invention provides a new
`mapping tool to substitute the conventional keyboard motion
`mapping table, and the mappingtoolofthe present invention
`can also get rid of limitation in keyboard using a remote
`device as the input device.
`Refer conjunctively to FIGS. 1A and 1B, wherein FIG. 1A
`shows a diagram for an embodiment of the mapping tool
`according to the present invention, and FIG. 1B shows a
`flowchart for the method of producing the mapping tool
`according to the present invention. In implementation, the
`mapping tool set forth hereinafter may be a software appli-
`cation.
`
`In FIG. 1A, the mapping tool 10' according to the present
`invention is linked with the original keyboard mappingtable
`10, wherein the Up key (1), Down key (|), Left key (<-) and
`Right key (>) each represents respective direction key on the
`keyboard, while the alphabets A, A' indicate jump up motions,
`the alphabetsB, B' indicate jump down motions, the alphabets
`C, C' indicate forward motionsandthe alphabets D, D' are for
`backward motions. Each motion in the mapping tool 10'
`according to the present invention is not instructed by the
`keyboard, but enabled by aremote motion signal generated by
`an external remote device, and thenthe key press signal on the
`keyboard is simulated based on the generated remote motion
`signal so as to replace the effect of the keyboard mapping
`table 10, further using the remote motion signal to control the
`PC game.Details of the method for producing the mapping
`
`4
`tool 10' according to the present invention can be shown as
`FIG. 1B, and will be explained infra.
`In the method shown as FIG.1B, it generates a plurality of
`remote motion commands with an external remote device,
`and creates a remote motion database consisting ofthe remote
`motion commandsbased on the remote motion commands
`(S100), wherein such remote motion commands may be
`motions such as, but not limited thereto, swing up, swing
`down, swingleft, swing right, circling, swing upperright to
`lower left, swing upper left to lower right, stab forward or
`retract backward, then the mapping tool 10' determines on
`each remote motion commandto define an actual motion.
`
`Next, itreads the keyboard mappingtable 10 (S102) to further
`resolve the plurality of keyboard commandsandplurality of
`motion commands in the keyboard motion mappingtable 10
`(S104); upon completion of the resolution, the mapping tool
`10' appreciates the correspondence between the keyboard
`commandsin the keyboard motion mapping table 10 and the
`motion commands. Subsequently,
`the mapping tool 10'
`searches for the corresponding remote motion command
`based on the motion command (S106), and whenthe corre-
`sponding remote motion commandbeingsearchedis located,
`the mapping tool 10° links the remote motion command with
`the keyboard command included in the keyboard motion
`mapping table 10; as the linking operation is done, the pro-
`duction of the mapping tool 10' is completed (S108).
`Refer now conjunctively to FIGS. 2A and 2B, wherein
`FIG. 2A shows a diagram for the architecture of a PC game
`system having the mapping tool according to the present
`invention, and FIG. 2B shows a diagram for an embodiment
`of a PC gamesystem having the mapping tool according to
`the present invention. As shown in FIG.2B, the system com-
`prises a host 12, a remote device 14, a mapping tool 124 and
`a screen 16. The host 12 can be a desktop computer, and
`consists of a wireless reception device 120, a mapping tool
`124 and at least one PC game 122. The wireless reception
`device 120 can be a wireless receiver used to receive the
`remote motion signal transmitted from the remote device 14,
`and the wireless reception device 120 can employ various
`types of connection interfaces to connect to the host 12, and
`such connection interfaces may be a USB interface, IEEE
`interface or RS-232 interface. The PC game 122 has a key-
`board motion mapping table 1220, the keyboard motion map-
`ping table 1220 recording the correspondence between each
`motion command of the PC game and any key command
`pressed on a keyboard. The mapping tool 124 consists of a
`remote motion resolution section 1240 and a remote motion
`
`mapping table 1242, the remote motion resolution section
`1240 being used to resolve the remote motion signal and
`generating the remote motion mapping table 1242 based on
`the result of the resolution; meanwhile, the remote device 14
`controls the PC game 122 through the remote motion map-
`ping table 1242 anddisplays the control result on the screen
`16.

`
`As shown in FIG.2A, the mapping tool 124 can be loaded
`in the host 12 byat least two fashions. Thefirst approachis to
`download the mapping tool 124 includedin the server host 18
`to the host 12 via the network 20, and the second wayis to,
`with a recordable media 22, transfer the mapping tool 124
`includedin the recordable media 22 to the host 12 by manual
`loading. The said recordable media 22 may be a Compact
`Disk (CD), a floppy disc or a USB thumbdrive.
`The remote device 14 is used to generate a remote motion
`signal and transmit it to the wireless reception device 120.
`The remote device 14 consists of an inertia sensing module
`140, a sensing signal operation unit 142 and a wireless trans-
`mission module 144. The inertia sensing module 140 can

`sense the acceleration and angular speed ofthe remote motion
`that the user performs through the remote device 14 along X
`axis, Y axis and Z axis and accordingly generatesa signal; in
`the present embodiment, the remote device 14 is held in hand
`by the user. The inertia sensing module 140 consists of at least
`one accelerometer or at least one gyroscope. The sensing
`signal operation unit 142 is used to receive the acceleration
`and angular speed of the remote motion generated by the
`inertia sensing module 140, and generates the remote motion
`signal indicating the acceleration and angular speed of the
`remote motion through computation; the wireless transmis-
`sion module 144 receives the remote motion signal generated
`by the sensing signal operation unit 142, further transmitting
`such a remote motion signal to the wireless reception device
`120 wirelessly (e.g. Bluetooth™, Radio Frequency)
`Refer now conjunctively FIGS. 2A, 2B and 3, wherein FIG.
`3 showsa flowchart for the operation method of a PC game
`using the mapping tool according to the present invention.
`Initially, the userfirst loads in at least one PC gamecontaining
`the keyboard motion mapping table 1220 (S200), the key-
`board motion mapping table 1220 recording the correspon-
`dence between each motion command of the PC game and
`any key commandpressed on a keyboard. The PC game 122
`may be an action game,a heuristic game, an adventure game,
`a shooting game, a simulation game, a sport gameora stra-
`tegic game, shown on the screen 16 of FIG. 2A as a tennis
`sport game. Next,it installs the mapping tool 124 into the host
`12 (S202), the mapping tool 124 comprising a remote motion
`resolution section 1240 and a remote motion mapping table
`1242. The mapping tool 124 can beinstalled in two ways; the
`first approach is to download the mapping tool 124 included
`in the serverhost 18 to the host 12 via the network 20 and then
`install it, and the second wayis to, with a recordable media 22
`(e.g. a Compact Disk (CD), a floppy disc or a USB thumb
`drive), install the mapping tool 124 stored therein into the host
`12.
`
`The wireless reception device 120 of the host 12 receives
`the remote motion signal transmitted by the remote device 14
`(S204), the remote motion signal being the signal generated
`by the acceleration and angular speed of the remote motion
`that the user performs through the remote device 14 along X
`axis, Y axis and Z axis, and the remote motion resolution
`section 1240 of the mapping tool 124 receives the remote
`motion signal transmitted by the wireless reception device
`120, then the remote motion resolution section 1240 resolve
`the received remote motion signal (S206). The remote motion
`resolution section 1240 can be a motion algorithm which
`resolves the meaning ofthe remote motion signal based on the
`rules defined in the motion algorithm, and creates a remote
`motion database with each of the resolved remote motion
`
`signal, in which the remote motion database can be defined
`beforehand. The mapping tool 124 next separates the motion
`command and keyboard key commandincludedin the key-
`board motion mapping table 1220 to acquire the keyboard key
`command (S208), and the mapping tool 124 links the
`resolved remote motion signal stored in the remote motion
`database with the separated keyboard key command ofthe
`keyboard motion mapping table 1220 (S210); upon comple-
`tion of such a linkage, the production of the remote motion
`mapping table 1242 is done. The mapping tool 124 simulates
`the keyboard key signal based on the remote motion signal
`through the remote motion mapping table 1242 (S212), and at
`this moment, the user can now operate the PC gameusing the
`mapping tool 124 (S214).
`The mapping tool 124 according to the present invention
`can replace the conventional keyboard motion mapping table
`1220. It senses the acceleration and angular speed generated

`by the user’s body with the inertia sensing module 140 of the
`remote device 14, thereby creating signals indicating motion
`states of the user’s body such as rotation, rhyme, swing or
`force, then transmitting wirelessly the generated remote state
`signal to the host 12; in this way, it is possible to provide the
`feature of high sensitivity, thus satisfying the demand for
`real-time control. Through the resolution on the remote state
`signal performed by the remote motion resolution section
`1240 ofthe mapping tool 124 and then using the mapping tool
`124 to operate the PC game,it allows the present invention to
`meet the requirement for real-time operation of high sensi-
`tivity.
`The present invention provides the following beneficial
`effects:
`
`1. the user, during PC gameoperations, may be exempted
`from the limitation ofkeyboard, better conforming to human-
`ized operation condition and achieving the goal of natural
`ergonomics, without causing injuries or negative influences
`on specific portions of user’s body (e.g. fingers). It is also
`possible to enhancethe effect of entertainment by exploiting
`the features of the mappingtool;
`2. the game design company needs not to abandon popular
`PC gamesdeveloped in earlier days, the usercan still play the
`existing PC game through the mappingtool; hence, the game
`design companyis able to significantly reduce the cost of
`game development.
`The aforementioned descriptions simply set forth the pre-
