Description
本發明係關於一種調整畫面顯示方向的方法及其相關裝置，尤指一種可提升使用便利性的調整畫面顯示方向的方法及其相關裝置。 The present invention relates to a method for adjusting a display direction of a screen and related devices, and more particularly to a method for adjusting a display direction of a screen and a related device thereof, which can improve convenience of use.
隨科技進步與發展，各式各樣可攜式電子裝置紛紛推出，如行動電話、個人數位助理、數位相機及平板電腦等。一般而言，上述之可攜式電子裝置皆具有影像顯示的功能，以供使用者查閱及瀏覽資料。考量使用者可能以不同方式手持或擺放可攜式電子裝置，目前可攜式電子裝置增設有重力感測器(gravity sensor，G-sensor)，使可攜式電子裝置的畫面顯示方向能依照可攜式電子裝置的擺放或手持方向而改變，以達到使用者不需改變自身的觀看位置(如扭轉頭部來觀看影像)，即可看到符合自身觀看角度的影像畫面，以提升使用上的便利性。 With the advancement and development of technology, a variety of portable electronic devices have been launched, such as mobile phones, personal digital assistants, digital cameras and tablets. In general, the portable electronic devices described above all have the function of image display for users to view and browse data. It is considered that the user may hold or place the portable electronic device in different ways. Currently, the portable electronic device is provided with a gravity sensor (G-sensor), so that the screen display direction of the portable electronic device can be The portable electronic device is changed in the orientation or the hand-held direction, so that the user does not need to change his or her viewing position (such as twisting the head to view the image), and the image image matching the viewing angle can be seen to enhance the use. Convenience.
關於重力感測器的運作原理，詳細說明如下。當使用者傾斜或轉動一行動電話時，行動電話中的一重力感測器偵測行動電話相較於水平面的三維軸向(即x、y、z軸)的角度，以及根據偵測到的x、y、z軸的角度，輸出相對應的感測參數至行動電話中的一判斷單元。判斷單元根據感測參數來判斷是否需調整行動電話的畫面顯示方向。舉例來說，當行動電話的擺放位置為直立(x=+90度、y=0度)時，輸出對應x軸的感測參數為“1”，而對應y軸的感測參數 為“0”；若使用者將行動電話向右旋轉呈橫置(x=0度、y=-90度)時，重力感測器會輸出對應x軸的感測參數為“0”，而對應y軸的感測參數為“1”。重力感測器的三軸感測參數亦可轉換為傾斜角度，可攜式電子裝置即可根據傾斜角度之變化，適當地調整影像的顯示方向。 The operation principle of the gravity sensor is described in detail below. When the user tilts or rotates a mobile phone, a gravity sensor in the mobile phone detects the angle of the mobile phone relative to the three-dimensional axis of the horizontal plane (ie, the x, y, and z axes), and based on the detected The angles of the x, y, and z axes output the corresponding sensing parameters to a judgment unit in the mobile phone. The judging unit judges whether the screen display direction of the mobile phone needs to be adjusted according to the sensing parameter. For example, when the position of the mobile phone is upright (x=+90 degrees, y=0 degrees), the sensing parameter corresponding to the x-axis is “1”, and the sensing parameter corresponding to the y-axis is It is “0”; if the user rotates the mobile phone to the right to be horizontal (x=0 degrees, y=-90 degrees), the gravity sensor outputs the sensing parameter corresponding to the x-axis as “0”, and The sensing parameter corresponding to the y-axis is "1". The three-axis sensing parameter of the gravity sensor can also be converted into an oblique angle, and the portable electronic device can appropriately adjust the display direction of the image according to the change of the tilt angle.
根據習知技術，透過重力感測器可偵測可攜式電子裝置的轉動狀態，因此當使用者旋轉可攜式電子裝置時，可攜式電子裝置會自動調整畫面的顯示方向，達到更便利的效果。然而，在某些情況下，使用者可能會不小心晃動到可攜式電子裝置，但此無意的晃動卻造成畫面方向的調整，使得使用者必需再次轉動可攜式電子裝置來恢復畫面方向，反而造成使用上的困擾。詳細說明如下。 According to the prior art, the rotation state of the portable electronic device can be detected through the gravity sensor, so when the user rotates the portable electronic device, the portable electronic device automatically adjusts the display direction of the screen to facilitate the display. Effect. However, in some cases, the user may accidentally shake to the portable electronic device, but this unintentional shaking causes the orientation of the picture to be adjusted, so that the user must turn the portable electronic device again to restore the picture orientation. On the contrary, it causes troubles in use. The details are as follows.
根據重力感測器的特性，當行動電話呈穩定狀態時，重力感測器能正確地感測行動電話的轉動狀態，但當使用者手持行動電話時，行動電話通常處於較不穩定的狀態(如使用者移動時所造成的晃動)，因此重力感測器無法精確地感測行動電話的轉動狀態，造成判斷單元誤判使用者意圖旋轉行動電話，而變更行動電話的畫面顯示方向。舉例來說，在使用者手持行動電話的情況下，若使用者的身體或手部傾斜時，重力感測器所偵測的x、y軸的感測參數會產生變化且可能超過預設值，因而造成使用者非預期之畫面方向的改變。有鑑於此，習知技術實有改進之必要。 According to the characteristics of the gravity sensor, when the mobile phone is in a steady state, the gravity sensor can correctly sense the rotation state of the mobile phone, but when the user holds the mobile phone, the mobile phone is usually in a relatively unstable state ( If the user shakes when the user moves, the gravity sensor cannot accurately sense the rotation state of the mobile phone, and the judgment unit misjudges the user's intention to rotate the mobile phone, and changes the screen display direction of the mobile phone. For example, in the case where the user holds the mobile phone, if the user's body or hand is tilted, the sensing parameters of the x and y axes detected by the gravity sensor may change and may exceed the preset value. , thus causing a change in the direction of the user's unexpected picture. In view of this, the prior art has been improved.
因此，本發明之主要目的在於提供一種調整畫面顯示方向的方法及其相關裝置，以避免非預期之畫面顯示方向的變更，進而提升 使用上的便利性。 Therefore, the main object of the present invention is to provide a method for adjusting the display direction of a screen and related devices to avoid unintended changes in the display direction of the screen, thereby improving Convenience in use.

In an embodiment, the first sensor 102 and the second sensor 104 can be a gravity sensor and a compass sensor. The gravity sensor detects the three-axis acceleration parameter of the portable electronic device 10, and further derives characteristic parameters such as acceleration and/or tilt angle, and can correspondingly know the placement direction of the portable electronic device (including the user's handheld Or placed on other objects, such as the desktop).

請參考第2圖，其為本發明實施例一畫面顯示方向調整方法20的流程示意圖。畫面顯示方向調整方法20可用於具有螢幕畫面顯示功能的一可攜式電子裝置(如智慧型手機、平板電腦或個人數位助理等)中，並包含有以下步驟： Please refer to FIG. 2 , which is a schematic flowchart of a screen display direction adjustment method 20 according to an embodiment of the present invention. The screen display direction adjustment method 20 can be used in a portable electronic device (such as a smart phone, a tablet computer or a personal digital assistant) having a screen display function, and includes the following steps:
步驟200：開始。 Step 200: Start.
步驟202：偵測至少兩個感測器之特性參數。 Step 202: Detect characteristic parameters of at least two sensors.
步驟204：根據第一感測器之特性參數，判斷是否滿足畫面顯 示方向調整的第一條件。 Step 204: Determine whether the screen display is satisfied according to the characteristic parameter of the first sensor The first condition of the direction adjustment is shown.

步驟208：根據第一條件和第二條件的判斷結果，判斷是否改變畫面顯示方向。 Step 208: Determine whether to change the screen display direction according to the determination result of the first condition and the second condition.
步驟210：結束。 Step 210: End.
根據畫面顯示方向調整方法20，可攜式電子裝置透過多個感測器所偵測到不同的特性參數，用以判斷特性參數是否滿足可攜式電子裝置中預設的條件，進而判斷是否需調整可攜式電子裝置的畫面顯示方向。感測器可為重力感測器(gravity sensor，G-sensor)、羅盤感測器(compass)或陀螺儀(gyro meter)。重力感測器用來偵測可攜式電子裝置的三軸加速度參數，進而推算出加速度和/或傾斜角度等特性參數，並可對應得知可攜式電子裝置的擺放方向(包含使用者手持或擺放於其他物體上，例如桌面)。羅盤感測器用來偵測可攜式電子裝置相對於地球磁場的方位夾角的特性參數，並可對應得知可攜式電子裝置的螢幕方向。於一實施例中，陀螺儀的特性參數為角速度。 According to the screen display direction adjustment method 20, the portable electronic device detects different characteristic parameters through multiple sensors, and determines whether the characteristic parameter meets the preset condition in the portable electronic device, thereby determining whether it is required Adjust the screen display direction of the portable electronic device. The sensor can be a gravity sensor (G-sensor), a compass sensor or a gyro meter. The gravity sensor is used to detect the three-axis acceleration parameter of the portable electronic device, thereby deriving characteristic parameters such as acceleration and/or tilt angle, and correspondingly knowing the orientation of the portable electronic device (including the user's hand-held Or placed on other objects, such as the desktop). The compass sensor is used to detect the characteristic parameter of the azimuth angle of the portable electronic device with respect to the earth's magnetic field, and can correspond to the screen direction of the portable electronic device. In an embodiment, the characteristic parameter of the gyroscope is angular velocity.
傳統使用單一感測器來判斷是否需要改變畫面顯示方向的缺點在於，某些狀況下感測器無法正確判斷出可攜式電子裝置的所有擺放狀態。再者，單一感測器的變化量無法反映出可攜式電子裝置相對於使用者的觀看方向。舉例來說，當使用者將智慧型手機平放於桌面上，並且從直向(portrait)轉為橫向(landscape)擺放時，於先前技術中因重力感測器之變化量不滿足改變畫面顯示方向的條 件，智慧型手機不會調整畫面顯示方向，因此使用者必須將智慧型手機橫向直立起來以改變畫面顯示方向。而本發明可根據重力感測器之狀態來判斷智慧型手機目前的擺放狀態，進而再根據羅盤感測器的變化來判斷螢幕方向是否改變。如果羅盤感測器的變化顯示為直向平放轉為橫向平放，則智慧型手機對應改變畫面顯示方向。如果羅盤感測器的變化顯示仍為直向平放，則智慧型手機不會改變畫面顯示方向。 A disadvantage of using a single sensor to determine whether it is necessary to change the display direction of the screen is that the sensor cannot correctly determine all the placement states of the portable electronic device under certain conditions. Moreover, the amount of change of the single sensor does not reflect the viewing direction of the portable electronic device relative to the user. For example, when the user puts the smart phone on the desktop and shifts from the portrait to the landscape, the change in the gravity sensor does not satisfy the change screen in the prior art. Bar showing direction The smart phone does not adjust the orientation of the screen, so the user must erect the smartphone horizontally to change the orientation of the screen. The invention can judge the current state of the smart phone according to the state of the gravity sensor, and then judge whether the screen direction changes according to the change of the compass sensor. If the change of the compass sensor is displayed as a straight flat to a horizontally flat, the smart phone changes the display direction of the screen. If the change in the compass sensor is still flat, the smartphone will not change the orientation of the screen.
又或者，使用者持拿智慧型手機的方式是與地面呈一傾斜角度，並且向左或向右傾斜智慧型手機時，重力感測器的變化量會超過預設應改變畫面顯示方向的臨界值，先前技術的判斷法則會因此對應改變螢幕顯示方向，例如從直向顯示改為橫向顯示。但在此情況下使用者仍是以直向觀看智慧型手機，因此造成誤判。本發明的畫面顯示方向調整方法會在判斷重力感測器之變化量超過預設臨界值後，再根據羅盤感測器的變化量來判斷智慧型手機的螢幕方向是否改變。如果羅盤感測器的變化量顯示仍與原先螢幕方向一致，則智慧型手機不會改變畫面顯示方向；反之，則改變畫面顯示方向。 Or, the way the user holds the smart phone is at an oblique angle to the ground, and when tilting the smart phone to the left or right, the amount of change of the gravity sensor exceeds the limit that should change the display direction of the screen. Values, prior art judgments will therefore change the display orientation of the screen accordingly, for example from a straight display to a horizontal display. However, in this case, the user still watches the smart phone in a straight direction, thus causing a misjudgment. The method for adjusting the screen display direction of the present invention determines whether the screen direction of the smart phone changes according to the amount of change of the compass sensor after determining that the amount of change of the gravity sensor exceeds a preset threshold. If the change amount display of the compass sensor is still consistent with the original screen orientation, the smart phone will not change the screen display direction; otherwise, the screen display direction will be changed.
接著請參考第3圖，其為本發明另一實施例之畫面顯示方向調整流程30的示意圖。如第3圖所示，可攜式電子裝置偵測至少兩個感測器之特性參數(步驟300)，例如重力感測器和羅盤感測器。在可攜式電子裝置取得感測器所測得的特性參數後，可攜式電子裝置根據其中一個感測器之特性參數，判斷可攜式電子裝置的擺放方向(步驟302)，以及根據另一個感測器之特性參數，判斷可攜式電子裝置的螢幕方向(步驟304)。因此，可攜式電子裝置能根據擺放方 向與螢幕方向，調整可攜式電子裝置的畫面顯示方向(步驟306)。簡單來說，本發明實施例中的可攜式電子裝置透過多個感測器所偵測到不同的特性參數，用以得知可攜式電子裝置的擺放狀態及螢幕方向，進而判斷是否需調整可攜式電子裝置的畫面顯示方向(或於另一實施例，判斷擺放狀態及螢幕方向是否滿足畫面顯示方向調整的第一條件及第二條件，以決定是否調整畫面顯示方向)。 Next, please refer to FIG. 3 , which is a schematic diagram of a screen display direction adjustment process 30 according to another embodiment of the present invention. As shown in FIG. 3, the portable electronic device detects characteristic parameters of at least two sensors (step 300), such as a gravity sensor and a compass sensor. After the portable electronic device obtains the characteristic parameter measured by the sensor, the portable electronic device determines the placement direction of the portable electronic device according to the characteristic parameter of one of the sensors (step 302), and according to Another characteristic parameter of the sensor determines the screen orientation of the portable electronic device (step 304). Therefore, the portable electronic device can be placed according to the placement In the direction of the screen, the screen display direction of the portable electronic device is adjusted (step 306). Briefly, the portable electronic device in the embodiment of the present invention detects different characteristic parameters through a plurality of sensors, and is used to determine the placement state and the screen direction of the portable electronic device, thereby determining whether It is necessary to adjust the screen display direction of the portable electronic device (or in another embodiment, determine whether the placement state and the screen direction satisfy the first condition and the second condition of the screen display direction adjustment to determine whether to adjust the screen display direction).
關於畫面顯示方向調整的條件說明，請參考第4圖，其為本發明實施例一畫面顯示方向調整方法40的示意圖。如第4圖所示，可攜式電子裝置偵測第一感測器與第二感測器的特性參數(步驟400)。在可攜式電子裝置取得第一感測器所測得的第一特性參數後，可攜式電子裝置判斷第一特性參數的變化量是否超過第一臨界值(步驟402)。若第一特性參數的變化量超過第一臨界值時，可攜式電子裝置判斷第二感測器所測得的第二特性參數是否超過第二臨界值(步驟404)。若第二特性參數超過第二臨界值時，可攜式電子裝置調整畫面資料的尺寸與解析度，並旋轉畫面顯示方向(步驟410~412)。相反地，若第二特性參數未超過第二臨界值時，可攜式電子裝置不旋轉畫面顯示方向(步驟414)。另一方面，若第一特性參數的變化量未超過第一臨界值時，可攜式電子裝置接著判斷第一特性參數是否符合第一狀態(例如第一特性參數所對應之方向是否符合可攜式電子裝置目前的擺放方向)(步驟406)。若第一特性參數符合第一狀態時，可攜式電子裝置判斷第二特性參數是否符合第二狀態(例如第二特性參數所對應之方向是否符合可攜式電子裝置之螢幕方向)(步驟408)。若第二特性參數符合第二狀態時，可攜式 電子裝置調整畫面資料的尺寸與解析度，並旋轉畫面顯示方向(步驟410~412)。相反地，若第一特性參數不符合第一狀態或第二特性參數不符合第二狀態時，可攜式電子裝置不旋轉畫面顯示方向(步驟414)。 For a description of the conditions for the screen display direction adjustment, please refer to FIG. 4, which is a schematic diagram of a screen display direction adjustment method 40 according to an embodiment of the present invention. As shown in FIG. 4, the portable electronic device detects characteristic parameters of the first sensor and the second sensor (step 400). After the portable electronic device obtains the first characteristic parameter measured by the first sensor, the portable electronic device determines whether the amount of change of the first characteristic parameter exceeds the first critical value (step 402). If the amount of change of the first characteristic parameter exceeds the first threshold, the portable electronic device determines whether the second characteristic parameter measured by the second sensor exceeds the second threshold (step 404). If the second characteristic parameter exceeds the second critical value, the portable electronic device adjusts the size and resolution of the screen data, and rotates the screen display direction (steps 410-412). Conversely, if the second characteristic parameter does not exceed the second threshold, the portable electronic device does not rotate the screen display direction (step 414). On the other hand, if the amount of change of the first characteristic parameter does not exceed the first threshold, the portable electronic device then determines whether the first characteristic parameter meets the first state (eg, whether the direction corresponding to the first characteristic parameter is compatible with the portability The current orientation of the electronic device) (step 406). If the first characteristic parameter meets the first state, the portable electronic device determines whether the second characteristic parameter meets the second state (for example, whether the direction corresponding to the second characteristic parameter meets the screen orientation of the portable electronic device) (step 408) ). Portable if the second characteristic parameter meets the second state The electronic device adjusts the size and resolution of the screen material and rotates the screen display direction (steps 410 to 412). Conversely, if the first characteristic parameter does not conform to the first state or the second characteristic parameter does not conform to the second state, the portable electronic device does not rotate the screen display direction (step 414).
此外，請參考第5圖，其為本發明一實施例之畫面顯示方向變更的示意圖。如第5圖所示，可攜式電子裝置可為一行動電話50。假設使用者手持行動電話50或平放於桌面，且行動電話50的指向是朝北方，此時螢幕單元500的顯示方向符合直向之行動電話50。當使用者旋動行動電話至橫向時，行動電話50的指向會轉朝東方。在此情況下，除了軸向變化量之外，地磁偏移量亦有改變。根據本發明實施例，當軸向變化量與地磁偏移量皆大於其預設值時，可確認行動電話50為使用者所旋轉，並自動調整螢幕單元500的顯示方向，否則不會調整畫面顯示方向(如僅有軸向變化量大於預設值)，藉以避免使用者的移動或晃動，造成非預期之畫面方向改變，而影響使用者的觀看。相較之下，習知技術僅根據軸向變化量，來決定是否變更畫面顯示方向，可能會造成不必要的調整畫面顯示方向。舉例來說，使用者手持行動電話且行動電話的指向是朝北方，當使用者移動身體時，可能晃動到行動電話，造成軸向變化量超過預設值。在此情況下，雖然行動電話的指向仍朝北方，但行動電話仍會調整畫面顯示方向，造成非預期之畫面方向改變。 In addition, please refer to FIG. 5, which is a schematic diagram of a screen display direction change according to an embodiment of the present invention. As shown in FIG. 5, the portable electronic device can be a mobile phone 50. It is assumed that the user holds the mobile phone 50 or lies on the desktop, and the pointing of the mobile phone 50 is toward the north, and the display direction of the screen unit 500 is in line with the direct mobile phone 50. When the user rotates the mobile phone to the landscape, the pointing of the mobile phone 50 turns to the east. In this case, in addition to the amount of axial change, the amount of geomagnetic offset also changes. According to the embodiment of the present invention, when both the axial change amount and the geomagnetic offset amount are greater than the preset value, it can be confirmed that the mobile phone 50 is rotated by the user, and the display direction of the screen unit 500 is automatically adjusted, otherwise the screen is not adjusted. The display direction (such as only the amount of axial change is greater than the preset value), in order to avoid the user's movement or shaking, causing unintended changes in the orientation of the picture and affecting the user's viewing. In contrast, conventional techniques only determine whether to change the screen display direction based on the amount of axial change, which may cause unnecessary adjustment of the screen display direction. For example, the user holds the mobile phone and the mobile phone is pointed to the north. When the user moves the body, it may shake to the mobile phone, causing the amount of axial change to exceed a preset value. In this case, although the mobile phone is still pointing north, the mobile phone will still adjust the direction of the screen display, causing unexpected changes in the direction of the picture.
第6圖繪示本發明另一實施例之畫面顯示方向變更的示意圖。於此實施例中假設使用者手持行動電話60且行動電話60的指向是朝北方，此時螢幕單元600的顯示方向符合直向之行動電話60。當 使用者左右旋轉行動電話60時，軸向變化量會大於預設值，然而地磁偏移量不會有太大改變，亦即行動電話的指向依然朝向北方。在此情況下，因地磁偏移量沒有改變，因此行動電話60不會調整畫面顯示方向。 FIG. 6 is a schematic diagram showing a change of a display direction of a screen according to another embodiment of the present invention. In this embodiment, it is assumed that the user holds the mobile phone 60 and the pointing of the mobile phone 60 is toward the north. At this time, the display direction of the screen unit 600 conforms to the direct mobile phone 60. when When the user rotates the mobile phone 60 left and right, the amount of axial change will be greater than the preset value, but the geomagnetic offset will not change much, that is, the pointing of the mobile phone is still facing the north. In this case, since the geomagnetic offset does not change, the mobile phone 60 does not adjust the screen display direction.
除此之外，可攜式電子裝置可參考陀螺儀的變化量來判斷可攜式電子裝置的移動狀態，並藉此判斷使用者之觀看方向是否改變，例如由坐立直向持拿方式改為側躺直向持拿方式。上述各種感測器僅為一般可攜式電子裝置可能具有之感測器種類的範例，本發明可適用之感測器類型不限於此。 In addition, the portable electronic device can determine the moving state of the portable electronic device by referring to the amount of change of the gyroscope, and thereby determine whether the viewing direction of the user changes, for example, changing from sitting upright to holding. The side is lying straight and holding the way. The above various sensors are only examples of the types of sensors that a general portable electronic device may have, and the types of sensors to which the present invention is applicable are not limited thereto.
以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。 The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
