The
為便於理解,須先說明地是,於本實施例中,「畫面」所指的是螢幕上顯示出來的完整的像素資料,由函式庫產生。例如,若螢幕的解析度為800x600,則此螢幕即有480000個像素,由每個像素的顏色資料構成的畫面即為使用者在螢幕上看到的畫面。「畫面資料」所指的是構成一個畫面的原始資料,由應用程式產生。畫面資料可包括文字、圖片、二進制資料(Binary Data)、應用程式介面(Application Programming Interface;API)、函數(Function)、結構化資料(如:XML)、或其他方式表示(如:遊戲應用程式裡的每一個角色都可由一張圖片表示)。「桌面畫面」所指的是於裝置開機後,作業系統顯示之最初的介面畫面。「應用程式識別碼」指的是每個應用程式之獨特的識別碼,用來辨識應用程式。「裝置識別碼」指的是每個裝置之獨特的識別碼,用來辨識裝置。舉例來說,裝置識別碼可為一裝置之網際網路通訊協定位址(IP)或者一裝置本身獨有的識別碼(Unique Identifier;UID),本發明於此並不限制。 For ease of understanding, it must be explained first that in this embodiment, the "frame" refers to the complete pixel data displayed on the screen, which is generated by the library. For example, if the resolution of the screen is 800x600, the screen has 480000 pixels, and the picture formed by the color data of each pixel is what the user sees on the screen. "Screen data" refers to the original data that constitutes a screen, which is generated by the application. Screen data can include text, pictures, binary data (Binary Data), application programming interface (API), function (Function), structured data (such as: XML), or other means (such as: game application Each role in this can be represented by a picture). "Desktop screen" refers to the initial interface screen displayed by the operating system after the device is turned on. "Application ID" refers to the unique ID of each application, which is used to identify the application. "Device ID" refers to the unique ID of each device, used to identify the device. For example, the device identification code can be an Internet Protocol address (IP) of a device or a unique identifier (UID) of the device itself, and the present invention is not limited herein.
除此之外,「事件(Event)」所指的是使用者透過輸入裝置,如前述之第一顯示單元12或第二顯示單元22選擇欲使用之應用程式後,輸入裝置所產生的資料,其中事件包含裝置識別碼。舉例來說,若事件是由第一顯示單元12產生的,事件中所包含的裝置識別碼便是對應於第一裝置10,若事件是由第二顯示單元22產生的,事件中所包含的裝置識別碼便是對應於第二裝置20。此外,事件還包含使用者的輸入資料。舉例來說,若使用者透過觸控螢
幕或滑鼠點選應用程式圖示,或透過鍵盤按鍵點擊選擇應用程式,則事件可包含使用者透過觸控螢幕或滑鼠點選的位置座標,或包含鍵盤按鍵的點擊資料。
In addition, "Event" refers to the data generated by the input device after the user selects the application to be used through the input device, such as the aforementioned
前述所定義之各名詞於接續的敘述中均將用以說明本實施例所提供之多裝置系統1,但於接續的敘述中前述各名詞之定義便不再贅述。
The nouns defined above will be used to describe the
於本實施例中,中央處理器14係運作單一作業系統。在尚未有使用者操作第一裝置10或第二裝置20時,中央處理器14將應用程式啟動器L所產生的桌面畫面傳送至第一顯示單元12,並控制其顯示桌面畫面。此外,透過第一通訊單元16與第二通訊單元26之間的資料傳輸,中央處理器14亦將應用程式啟動器L所產生的另一桌面畫面傳送至微控制器24。接著,微控制器24傳送桌面畫面至第二顯示單元22,以控制其顯示桌面畫面。須說明地是,桌面畫面經第一顯示單元12或第二顯示單元22顯示即呈現中央處理器14所運作之作業系統之個別的桌面畫面,以供第一使用者和第二使用者操作。
In this embodiment, the
根據第一使用者與第二使用者的操作,第一顯示單元12與第二顯示單元22能夠分別呈現作業系統不同的運作畫面。於此,第一顯示單元12與第二顯示單元22可為觸控螢幕或一般顯示螢幕,但本發明並不限定。
According to the operations of the first user and the second user, the
須說明地是,於本實施例中,中央處理器14之功能主要係用以運作作業系統,而微控制器24其功能較單純地係為發送與接收指令,以及控制第二顯示單元22顯示所接收的資料。關於中央處理器14與微控制器24之間的工作機制,將於以下敘述中進行說明。
It should be noted that in this embodiment, the function of the
請同時參照圖1與圖2,圖2為根據本發明一例示性實施例所繪示之多裝置系統之作業系統的方塊圖。 Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 2 is a block diagram of an operating system of a multi-device system according to an exemplary embodiment of the present invention.
多裝置系統1之作業系統的軟體架構係如圖2所示,多裝置系統1之作業系統至少包括有系統核心K、函式庫F、執行環境E與應
用程式框架AF,其中函式庫F至少包括伺服單元S,且應用程式框架AF上建構有複數個應用程式A、B與應用程式啟動器(Launcher)L。此外,函式庫F與執行環境E係架構於系統核心K之上,應用程式框架AF之下。
The software architecture of the operating system of the
值得注意地是,於本實施例中,應用程式A指的是程式開發者依使用者需求進行客製化編程所完成的應用程式,可同時由第一使用者與第二使用者選擇並被啟動與獨立操作。例如,應用程式A可為地圖應用程式,第一使用者與第二使用者可同時使用此地圖應用程式,第一使用者可瀏覽台灣的地圖,第二使用者可瀏覽美國的地圖,雙方互不影響。 It is worth noting that, in this embodiment, the application program A refers to the application program completed by the program developer according to the user's needs for customized programming, which can be selected by the first user and the second user at the same time. Start-up and independent operation. For example, application A can be a map application. The first user and the second user can use this map application at the same time. The first user can browse the map of Taiwan, and the second user can browse the map of the United States. Does not affect.
進一步說明,當第一使用者操作第一裝置10選擇應用程式A時(例如,點選第一顯示單元12所顯示之應用程式A的圖示),應用程式A可被啟動,供第一使用者使用。此時,第二使用者仍可操作第二裝置20選擇應用程式A(例如,點選第二顯示單元22所顯示之應用程式A的圖示),使應用程式A再次被啟動,供第二使用者使用。相同地,當第二使用者操作第二裝置20選擇應用程式A時(例如,點選第二顯示單元22所顯示之應用程式A的圖示),應用程式A可被啟動,供第二使用者使用。此時,第一使用者仍可操作第一裝置10選擇應用程式A(例如,點選第一顯示單元12所顯示之應用程式A的圖示),使應用程式A再次被啟動,供第一使用者使用。
To further illustrate, when the first user operates the
也就是說,於本實施例中,應用程式啟動器L可重複地啟動同一個應用程式A,即第一使用者與第二使用者可同時以不同的用戶身分透過第一裝置10與第二裝置20個別地啟動並接續地操作應用程式A,不會互受牽制。
That is to say, in this embodiment, the application launcher L can repeatedly launch the same application A, that is, the first user and the second user can pass through the
另一方面,如圖2所示,建構在應用程式框架AF上的應用程式亦可為應用程式B。須說明地是,以使用Android系統之裝置為例,應用程式B所指的是裝置中系統預載的應用程式,如:電子郵件程式、簡訊程式、行事曆、瀏覽器、聯絡人與其它應用程式,或者 是由使用者自行由程式商店(如:Google PlayTM)中下載與安裝的應用程式,如:地圖、LINETM、微信…等。 On the other hand, as shown in Figure 2, the application built on the application framework AF can also be the application B. It should be noted that, taking the device using the Android system as an example, application B refers to the applications pre-installed in the device system, such as email programs, SMS programs, calendars, browsers, contacts, and other applications Programs, or applications downloaded and installed by the user from a program store (e.g. Google Play TM ), such as maps, LINE TM , WeChat... etc
值得注意地是,應用程式B與應用程式A的差別在於,應用程式B無法同時由第一使用者與第二使用者透過第一裝置10與第二裝置20個別地啟動與操作。
It is worth noting that the difference between the application B and the application A is that the application B cannot be activated and operated by the first user and the second user through the
進一步說明,當第一使用者與第二使用者均未透過第一顯示單元12或第二顯示單元22選擇任何應用程式A或B時,第一顯示單元12與第二顯示單元22所顯示的桌面畫面裡均可同時包括有應用程式A與B的圖示。然而,當第一使用者透過第一顯示單元12選擇了應用程式B時,於第二顯示單元22所呈現之系統運作畫面中便不會出現應用程式B的圖示。換言之,當第一使用者已啟動應用程式B時,第二使用者便無法再次啟動應用程式B。另一方面,當第二使用者透過第二顯示單元22選擇了應用程式B時,於第一顯示單元12所呈現之系統運作畫面中便不會出現應用程式B的圖示。換言之,當第二使用者已啟動應用程式B時,第一使用者便無法再次啟動應用程式B。
To further illustrate, when neither the first user nor the second user selects any application A or B through the
或者,當第一使用者透過第一顯示單元12選擇了應用程式B時,於第二顯示單元22所呈現之系統運作畫面中仍顯示應用程式B的圖示,但此時若第二使用者透過第二顯示單元22選擇了應用程式B,中央處理器14便會發出錯誤訊息,透過第一通訊單元16與第二通訊單元26之間的資料傳輸傳送到微控制器24,再由微控制器24控制第二顯示單元22顯示此錯誤訊息。換言之,當第一使用者已啟動應用程式B時,第二使用者便無法再次啟動應用程式B。另一方面,當第二使用者透過第二顯示單元22選擇了應用程式B時,於第一顯示單元12所呈現之系統運作畫面中仍顯示應用程式B的圖示,但此時若第一使用者透過第一顯示單元12選擇了應用程式B,中央處理器14便會發出錯誤訊息,並控制第一顯示單元12顯示
此錯誤訊息。換言之,當第二使用者已啟動應用程式B時,第一使用者便無法再次啟動應用程式B。
Or, when the first user selects application B through the
接下來,為便於理解,以下敘述中之作業系統係舉例為Android系統,但本發明於此並不限制作業系統的類型。以Android系統來說,執行環境E即為Android執行環境(Android Runtime),且系統核心K即為Linux核心(Linux Kernel)。此外,函式庫F包含多種由程式語言撰寫的系統元件,以供應用程式開發者使用。於Android系統下,當一裝置開機時,中央處理器便開始運作作業系統,作業系統裡的系統核心K便啟動執行環境E與函式庫F,由執行環境E啟動應用程式框架AF,由應用程式框架AF啟動應用程式啟動器L。當一使用者選擇任一應用程式A或B時,應用程式啟動器L便會啟動A或B。當應用程式A或B需要執行某個功能時,應用程式A或B可透過應用程式框架AF呼叫函式庫F中對應的函式,由函式庫F執行此函式。當應用程式啟動器L需要執行某個功能時,應用程式啟動器L亦可透過應用程式框架AF呼叫函式庫F中對應的函式,由函式庫F執行此函式。然Android系統之架構的詳細工作原理應可為本發明所屬技術領域中具有通常知識者理解,於此便不作更多細述。 Next, for ease of understanding, the operating system in the following description is an Android system as an example, but the present invention does not limit the type of operating system here. For the Android system, the execution environment E is the Android runtime (Android Runtime), and the system core K is the Linux kernel (Linux Kernel). In addition, the library F contains a variety of system components written in programming languages for use by application developers. Under the Android system, when a device is turned on, the central processing unit starts to operate the operating system. The system core K in the operating system starts the execution environment E and the library F. The execution environment E starts the application framework AF, and the application The application frame AF starts the application launcher L. When a user selects any application A or B, the application launcher L will start A or B. When the application A or B needs to perform a certain function, the application A or B can call the corresponding function in the library F through the application framework AF, and the library F executes the function. When the application launcher L needs to perform a certain function, the application launcher L can also call the corresponding function in the library F through the application framework AF, and the library F executes the function. However, the detailed working principles of the architecture of the Android system should be understood by those with ordinary knowledge in the technical field to which the present invention belongs, and will not be described in more detail here.
但須說明地是,於本實施例中,應用程式啟動器L本身也是一個應用程式,主要用以啟動應用程式A或B,但應用程式啟動器L的功能實際上亦可包含桌面的切換、應用程式快捷(Shortcut)功能、背景圖(Wallpaper)…等。 It should be noted that, in this embodiment, the application launcher L itself is also an application, which is mainly used to launch the application A or B, but the function of the application launcher L can actually include switching of the desktop, Application shortcut (Shortcut) function, background image (Wallpaper)... etc.
接著說明本實施例中應用程式如何由使用者選擇,以及由多裝置系統1啟動跟執行。由於以上敘述中已闡述應用程式A與B之差異,故於以下敘述中僅針對應用程式A如何由使用者選擇,以及由多裝置系統1啟動跟執行作說明。
Next, it will be explained how the application program in this embodiment is selected by the user, and activated and executed by the
當第一使用者透過第一顯示單元12選擇應用程式A(如:點選應用程式A的圖示)時,第一顯示單元12便會產生一第一事件,並
將此第一事件傳送至中央處理器14。當第二使用者透過第二顯示單元22選擇應用程式A(如:點選應用程式A的圖示)時,第二顯示單元22便會產生一第一事件,並將此第一事件傳送至微控制器24,透過第二通訊單元26與第一通訊單元16之間的資料傳輸,中央處理器14接收到此第一事件。
When the first user selects application A through the first display unit 12 (for example, clicks on the icon of application A), the
接著,此第一事件會由中央處理器14傳送至系統核心K,由系統核心K傳送至函式庫F,接著再由函式庫F傳送至應用程式框架AF,並由應用程式框架AF傳送至應用程式啟動器L。應用程式啟動器L接收第一事件後,便能根據此第一事件得知使用者選擇的應用程式A是哪個應用程式,並啟動此應用程式。
Then, this first event will be sent from the
於上述應用程式啟動器L啟動被選擇的應用程式A的過程中,應用程式啟動器L取得應用程式識別碼與裝置識別碼,將此二者包成一個指令,並傳送此指令至應用程式框架AF,由應用程式框架AF執行應用程式A並將此指令交予伺服單元S。伺服單元S接收此指令後,便會紀錄指令中的裝置識別碼與應用程式識別碼的對應關係。 In the process of the application launcher L starting the selected application A, the application launcher L obtains the application ID and the device ID, packs the two into one command, and sends this command to the application framework AF, the application framework AF executes the application A and passes this command to the server unit S. After the server unit S receives this command, it records the correspondence between the device identification code and the application program identification code in the command.
接下來,應用程式A會產生一啟動畫面資料,並將此啟動畫面資料傳給應用程式框架AF,由應用程式框架AF把此啟動畫面資料傳給函式庫F,由函式庫F產生一啟動畫面。函式庫F參考伺服單元S所記錄之裝置識別碼與應用程式識別碼的對應關係便能獲知一目標顯示裝置,於是函式庫F便把此啟動畫面傳送到此目標顯示裝置。若此目標顯示裝置為第一裝置10,函式庫F便將此啟動畫面傳送到中央處理器14,由中央處理器14再送到第一顯示單元12。若此目標顯示裝置為第二裝置20,函式庫F便將此啟動畫面傳送到中央處理器14,透過第一通訊單元16與第二通訊單元26之間的資料傳輸,由微控制器24接收此啟動畫面並控制第二顯示裝置22顯示此啟動畫面,如此一來,便完成應用程式A由多裝置系統1啟動跟執行的過程。
Next, application A will generate a splash screen data, and send the splash screen data to the application framework AF. The application framework AF sends the splash screen data to the library F, and the library F generates a Splash screen. The library F can learn a target display device by referring to the correspondence between the device identification code recorded by the server unit S and the application program identification code, and then the library F sends the startup screen to the target display device. If the target display device is the
接著說明本實施例中應用程式由多裝置系統1執行後如何被操作。同樣地,由於以上敘述中已闡述應用程式A與B之差異,故於以下敘述中僅針對應用程式A由多裝置系統1執行後如何被操作作說明。
Next, it will be explained how the application program is operated after being executed by the
當被選擇之應用程式A已由應用程式啟動器L啟動並由應用程式框架AF執行後,其畫面就顯示於第一顯示單元12或第二顯示單元22,第一使用者或第二使用者便可開始操作應用程式A。
When the selected application A has been activated by the application launcher L and executed by the application framework AF, its screen is displayed on the
當第一使用者點選第一顯示單元12所呈現之畫面的任一處以操作應用程式A時,第一顯示單元12便會產生一第二事件,並將此第二事件傳送至中央處理器14。當第二使用者點選第二顯示單元22所呈現之畫面的任一處以操作應用程式A時,第二顯示單元22便會產生一第二事件,並將此第二事件傳送至微控制器24,透過第二通訊單元26與第一通訊單元16之間的資料傳輸,微控制器24將此第二事件傳送至中央處理器14。
When the first user clicks on any place of the screen presented by the
接著,中央處理器14將此第二事件傳送至系統核心K,由系統核心K將此第二事件傳送至函式庫F。於是,函式庫F便根據第二事件得知裝置識別碼,並將此裝置識別碼交予伺服單元S。由於伺服單元S紀錄有裝置識別碼與應用程式識別碼的對應關係,因此伺服單元S能告知函式庫F此裝置識別碼所對應的是哪個應用程式A。當函式庫F得知此裝置識別碼所對應的應用程式A後,函式庫F透過應用程式框架AF將此第二事件傳給應用程式A,由應用程式A執行此第二事件。

〔實施例的可能功效〕 [Possible effects of the embodiment]
綜上所述,本發明所提供之多裝置系統至少具有以下優點: 首先,本發明所提供之多裝置系統係包括多個裝置,且該些裝置均於單一作業系統,相較於習知的多裝置系統來說,無須進行作業系統的切換,對於各裝置所發送的指令能直接地於單一作業系統下進行運算,減少了多裝置系統運作上的複雜度。 In summary, the multi-device system provided by the present invention has at least the following advantages: First of all, the multi-device system provided by the present invention includes multiple devices, and these devices are all in a single operating system. Compared with the conventional multi-device system, there is no need to switch the operating system. The instructions can be directly operated on a single operating system, reducing the complexity of the operation of a multi-device system.
再者,本發明所提供之多裝置系統中的多個裝置僅需其一設置有中央處理器來負責運算各裝置傳送來的指令,相較於習知的多裝置系統來說,無須於各獨立的裝置上均設置有中央處理器,也能流暢地進行事件判斷與指令運算,更能節省系統的設置成本。 Furthermore, in the multi-device system provided by the present invention, only one of the multiple devices in the multi-device system needs to be equipped with a central processing unit to be responsible for computing the instructions sent by each device. Compared with the conventional multi-device system, there is no need for each device. Independent devices are equipped with a central processing unit, which can also perform event judgment and instruction calculation smoothly, which can save system setup costs.
此外,本發明所提供之多裝置系統中,雖然多個裝置僅其一設置有中央處理器,不同的使用者仍可透過各自的裝置啟動並操作相同的應用程式,而不會受到同一應用程式僅能透過單一裝置啟動與操作的限制,提供了使用者相當大的使用彈性。 In addition, in the multi-device system provided by the present invention, although only one of the multiple devices is equipped with a central processing unit, different users can still activate and operate the same application through their respective devices without being affected by the same application. The limitation that only a single device can be activated and operated provides users with considerable flexibility.
以上所述僅為本發明之實施例,其並非用以侷限本發明之專利範圍。 The above are only the embodiments of the present invention, and they are not intended to limit the patent scope of the present invention.
