[Embodiment] In order to further understand the end point, structural features and functions of the present invention, the related embodiments and drawings are described in detail as follows: Please refer to FIG. 1 'which is a handheld device 1 according to an embodiment of the present invention. The schematic diagram of the block includes a processor 120, a three-axis acceleration sensor 110 and a power saving module 130. The three-axis acceleration sensor 110 has three reference axes (such as an X-axis, a y-axis, and a z-axis). When the handheld device 1 is placed in a certain state, such as horizontally placed on the desktop, three acceleration sensors are provided. 110 The measured tilt angle is the initial "reference angle. When the handheld device 100 is placed arbitrarily, the triaxial acceleration sensor 11 calculates the difference between the currently detected angle and the reference angle, and then changes the 201022926 (calculates the tilt angle of the handheld device 100. : Power saving module 130 series internal storage - the setting value of the power saving mode 131.

The processor 12 取得 obtains the tilt angle of the three-axis acceleration sensor 11 (M贞, And compared with the upper (four) ^ trigger angle. When the tilt angle meets the aforementioned trigger angle, it means that the handheld device 100 is in the state of "special (four) placement state" and the placement state is the user not #, not used, or It is not the state of the handheld device. In general, when the user views the kneading surface displayed by the handheld device (10), the user holds the handheld device more manually and the user will bow his head to the handheld device. The displayed picture. At this time, 'in order to match the user's gaze, the user will hold the hand-held device in a tilted manner to allow the user to view the picture Φ of the handheld device. (4) When Wei Wei W holds the device, the handheld device is placed on the table. The most common methods are horizontal placement, vertical placement, and side g placement (but not limited to three). Herein, for the sake of explanation, the assumption is made.) Since the handheld device exhibits any of the three-sided placement states, the user does not easily view the screen displayed by the handheld device 100. Therefore, the manufacturer or the user can preset the handheld device 100 to When any one of the above modes is placed, the tilt angle of the measurement of 2010201026 is measured as the trigger angle by the three-axis acceleration sensor 110. Although the processor 120 determines that the tilt angle meets the above-mentioned trigger angle, the processor 120 outputs a power saving. After receiving the power saving command, the power saving module 130 activates the set value of the foregoing power saving mode 131, and causes the handheld device 100 to enter the power saving mode 131.

Fig. 3A is a schematic view showing the state in which the handheld device of the present invention is placed horizontally according to an embodiment of the present invention. Fig. 3B is a schematic view showing the handheld device in a vertically placed state according to an embodiment of the present invention. Fig. 3C is a schematic view showing the state in which the hand-held device of the embodiment of the present invention is placed vertically. The flow of this method is explained as follows: One tilt angle of the handheld device 100 is detected (step S110). The triaxial acceleration sensor 110 of the handheld device 100 senses the movement or rest of the handheld device 1 in a horizontal or vertical plane. The user can use Φ to empirically set the placement state of the handheld device 100 to the trigger angle. As mentioned above, in order to match the user's gaze, the user generally holds the hand-held device in the hand so that the user can view the face displayed by the hand-held device. In this embodiment, when the handheld device 100 is in a horizontally placed state (as shown in FIG. 3A), in a vertically placed state (as shown in FIG. 3B), and in a vertically placed state (as shown in FIG. 3C). At the time, the user has the lowest chance of viewing the face of the screen. Therefore, the user or the manufacturer can preset the tilt angle of the handheld device 100 in this state of 2010. The trigger angle can be selected as the tilt angle of the three placement states (or only one of them, or two). • When the user randomly places the handheld device 100, the triaxial acceleration sensor 110 immediately detects the tilt angle of the current handheld device 1 and transmits it to the processor 120. It is judged whether or not the tilt angle of the hand-held device 100 conforms to any of the trigger angles (step S120). The processor 120 compares the tilt ® angle detected by the two-axis acceleration sensor 11 与 with the above, and all the trigger angles are compared one by one. When the tilt angle does not match any of the trigger angles, the processor 12 continues the current execution state and continuously detects the change in the tilt angle, that is, returns to step S110. When the tilt angle meets any of the trigger angles, the processor 12 determines whether any of the program modules 140 are being executed (step Si3〇). In the present embodiment, when the tilt angle conforms to any of the trigger angles, the hand-held device 1 is in one of a horizontal placement state, a vertical placement state, or a side vertical placement state. When the processor determines that the tilt angle meets the trigger angle, and any of the program modules 140 are being executed, the processor 120 sends a non-valued tube command to the power saving module 130 to activate the handheld device 1 The program module U0 is continuously executed (step S131). The processor ι2〇 continues the execution of the program module 140 until the program module 140 executes, or waits for computational resources (regardless of hardware resources or software resources) to form an idle state. 201022926: When the program module U is executed, it may use the data transmission module 150 to perform information transmission operations with the external device 16 , such as Bluetooth transmission technology, high-definition wireless transmission technology (Wi_Fi), Universal Serial Bus (USB) transmission technology or global interoperable microwave access... The processor 120 determines whether the program module 14 is executed or is in progress.
❹ 閒置（步驟测）。當㈣· 14G未執行完成或處於閒 置時，處理器120會持續判斷程序模紐14〇是否執行完成 或處於閒置（步驟S140)。 當程序模組140執行完成或處於閒置時，處理器 係發出一省電指令至省電模組130。省電模紐13〇在取得 省電指令後，會立即啟動省電模式131，令手持裝置上⑽ 進入省電模式131 (步驟S150)。 當傾斜角度符合任-觸發角度’且處理器12()判斷未 有任一程序模組140正執行中，處理器12〇會直接發出一 省電指令至省電模組13〇。省電模組13Q係根據此省電: 令啟動省電模式131，令手持裝置100進入省電模式 (步驟 S150)。 雖然本發明以前述之較佳實施例揭露如 ^ 上，然其並非 用以限定本發明，任何熟習相像技藝者’在 之精神和範圍内，所作更動與潤飾之等效替換，仍為月 明之專利保護範圍内。 ' ~ 發 【圖式簡單說明】 11 201022926 圖1 係本發明實施例之手持裝置之方塊示意圖； 圖2 係本發明實施例之節能方法之流程圖之一例； 圖3A係本發明實施例之手持裝置為水平置放狀態之示意 園， 圖3B係本發明實施例之手持裝置為豎直置放狀態之示意 圖；以及 圖3C係本發明實施例之手持裝置為侧面豎直置放狀態之 示意圖。 【主要元件符號說明】 100 手持裝置 110 三軸加速度傳感器 120 處理器 130 省電模組 131 省電模式 132 不值管模式 140 程序模組 150 資料傳輸模組 160 外部裝置 12闲 Idle (step test). When (4)·14G is not completed or is idle, the processor 120 continues to judge whether the program module 14 is performing or is idle (step S140). When the program module 140 is executed or is idle, the processor issues a power saving command to the power saving module 130. After the power saving mode button 13 has obtained the power saving command, the power saving mode 131 is immediately activated, and the handheld device (10) enters the power saving mode 131 (step S150). When the tilt angle meets the any-trigger angle' and the processor 12() determines that no program module 140 is being executed, the processor 12〇 directly issues a power-saving command to the power-saving module 13A. The power saving module 13Q is based on this power saving: the power saving mode 131 is activated, and the handheld device 100 is put into the power saving mode (step S150).
