200928865 九、發明說明： 【發明所屬之技術領域】 本發明關於一種可攜式電子裝置及其控制的方法，特 別關於一種可攜式電子裝置及其非接觸控制的方法。 【先前技術】 在目前的可攜式電子裝置技術中，接觸控制式的可攜 式電子裝置已發展地相當成熟。如圖1所示，其為習知觸 ® 控式可攜式電子裝置的外觀示意圖，使用者利用手指12 在可攜式電子裝置14的觸控式螢幕141上沿著不同方向 滑動、或是以不同程度的按壓，使得觸控式螢幕141接收 到特定的信號後而執行對應的欲啟動功能。 然而，不同的觸控式螢幕在操作時亦有不同的控制機 制，舉例來說，當此可攜式電子裝置的觸控式螢幕為電阻 式控制的觸控式螢幕時，則使用者的手指接觸螢幕時會導 Q 致部分波的傳遞受到阻擋，而透過設置於可攜式電子裝置 内部的檢測單元所偵測到的相對能量衰減量以提供給軟 體進行運算，進一步定位出手指所在的座標。 另一種常見的觸控機制則為電容式觸控，雖和電阻式 設計相當，但其主要是利用内外侧導電層產生均勻的低壓 電場，當手指接觸到螢幕，就會與外側導電層上的電場產 生電容耦合，而吸去微小的電流，再由偵測電極負責測量 各角落的電流進而算出手指的座標。 請再參照圖1所示，觸控式螢幕141皆必須利用一接 6 200928865 觸體（例如使用者的手指12)以直接接觸於觸控式螢幕 141上，使可攜式電子裝置14内的感應單元142得以感應 到使用者的手指12作動的方向及按壓的時間長短，並將 此些信號傳送至處理單元143内進行進一步的判斷並執行 對應的欲啟動功能。其中不同機制的觸控方法所需的接觸 體並不完全相同，對於電阻式的觸控機制而言，接觸體可 為導電體或非導電體^然而對於電容式的觸控機制而言， 接觸體則必須具有導電的特性以吸收微小的電流並導致 ® 電流分佈產生微量的變化。由於接觸體經常在觸控式螢幕 141上滑動，勢必造成觸控式螢幕141的表面上殘留許多 痕跡，例如使用者以手指12為接觸體時，經過長期使用 的觸控式螢幕141表面上會殘留許多指紋161或刮痕 162，因此影響可攜式電子裝置14的美觀甚至觸控功能。 因此，如何提供一種可攜式電子裝置及其非接觸控制 的方法，其係可藉由非接觸螢幕的控制方式，即能夠控制 Q 執行對應的欲啟動功能，不致於螢幕殘留痕跡而確保美 觀，長時間使用亦不會減損控制功能，已成為重要課題之 【發明内容】 有鑑於上述課題，本發明之目的為提供一種可攜式電 子裝置及其非接觸控制的方法，其藉由無線方法輸出無線 信號並接收該信號的折射信號，且在比對輸出與折射無線 信號之後，據以於對照表中尋找並執行相對應的欲啟動功 200928865 能。因此，可蘇山& 错由偵測使用者在邛攜式電子裝 應距離内的動作乜拈/ 戒置的有效感 接觸勞幕，故不目對應的欲啟動功能，而無需直接 亦不會因此減損控制功能時間的使用後在鸯幕殘留痕跡， 為達上述目的， -

Field of the Invention The present invention relates to a portable electronic device and a method of controlling the same, and more particularly to a portable electronic device and a method thereof for non-contact control. [Prior Art] In the current portable electronic device technology, the contact-controlled portable electronic device has been developed to be quite mature. As shown in FIG. 1 , it is a schematic diagram of the appearance of a conventional touch-controlled portable electronic device. The user uses the finger 12 to slide in different directions on the touch screen 141 of the portable electronic device 14 , or With different degrees of pressing, the touch screen 141 receives a specific signal and then performs a corresponding function to be activated. However, different touch screens also have different control mechanisms during operation. For example, when the touch screen of the portable electronic device is a resistively controlled touch screen, the user's finger When the screen is touched, the transmission of the partial wave is blocked, and the relative energy attenuation detected by the detecting unit disposed inside the portable electronic device is provided to the software for calculation to further locate the coordinate of the finger. . Another common touch mechanism is capacitive touch. Although it is equivalent to the resistive design, it mainly uses the inner and outer conductive layers to generate a uniform low-voltage electric field. When the finger touches the screen, it will be on the outer conductive layer. The electric field generates capacitive coupling, and a small current is drawn, and the detecting electrode is responsible for measuring the current at each corner to calculate the coordinates of the finger. Referring to FIG. 1 again, the touch screen 141 must be directly contacted with the touch screen 141 by using a 6 200928865 contact body (eg, the user's finger 12) to enable the portable electronic device 14 to The sensing unit 142 senses the direction in which the user's finger 12 is actuated and the length of time the button is pressed, and transmits the signals to the processing unit 143 for further determination and execution of the corresponding function to be activated. The contact body required by the touch method of different mechanisms is not completely the same. For the resistive touch mechanism, the contact body can be an electrical conductor or a non-conducting body. However, for a capacitive touch mechanism, the contact is The body must be electrically conductive to absorb small currents and cause a slight change in the current distribution. Since the contact body often slides on the touch screen 141, a lot of traces remain on the surface of the touch screen 141. For example, when the user uses the finger 12 as a contact body, the surface of the touch screen 141 that has been used for a long time will be A plurality of fingerprints 161 or scratches 162 remain, thus affecting the aesthetics and even the touch function of the portable electronic device 14. Therefore, how to provide a portable electronic device and a non-contact control method thereof can be controlled by a non-contact screen, that is, the Q can be controlled to perform a corresponding function to be activated, and the appearance of the screen is not preserved to ensure the appearance. In view of the above problems, it is an object of the present invention to provide a portable electronic device and a method for non-contact control thereof, which are output by a wireless method. The wireless signal receives and rejects the refraction signal of the signal, and after comparing and outputting the refracted wireless signal, the corresponding starting function 200928865 can be found and executed according to the comparison table. Therefore, the Sushan & error is detected by the user's effective action/stopping action within the distance of the portable electronic device, so the corresponding function is not required to be activated, and there is no need to directly or not This will detract from the residual traces of the control function after the use of the curtain, in order to achieve the above purpose, - to be willing / 6 4 (according to this Mao Mingzhi - kind of portable current Leigong installation, which includes - launch unit, - The sensing unit and the electronic device are equipped with a processing unit, wherein the _ two dumps are 7L early and the Ύ processing is electrically coupled to the salt metering unit. The unit and the transmitting unit are fired. ^ 耵 兀 以 以 以 以 以 以 以 以 以 以 以 以 以 ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο 而 ο 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而兀 (4) Refracting the look-up table to find and execute the corresponding function to be activated. The wireless signal may be an electromagnetic wave signal or a light wave signal. Meanwhile, according to the method of non-contact control of the present invention, it may be used to control the 4 stable type. Electronic device. This The method of contact control comprises the steps of: outputting a wireless signal in a wireless T mode; wirelessly receiving the refracted wireless signal; and comparing the rounded and refracted non-wire signal to one The refracting reference table finds and executes a corresponding function to be activated, wherein the wireless signal can be an electromagnetic wave signal or a light wave signal. According to the above, a configurable electronic device and a method thereof for non-contact control of the present invention It uses a wireless method to output and receive wireless signals, and finds the corresponding function to be activated in the refracting table according to the result of comparing the two signals. Finally, the processing unit is used to perform the function to be activated. In the present invention, the wireless method can be used to confirm the user's action within the effective sensing distance of the portable electronic device, so that no touch screen is required, that is, 200928865 can be used to enable the portable electronic device to switch differently. Compared with the conventional technology, the function of the hair is caused by traces on the screen and the disc is beautiful, and the long-term use will not detract from the control function. [Embodiment] Hereinafter, a portable electronic device and a method of non-contact control thereof according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein the same elements will be described with the same reference numerals. 2 is a block diagram showing the operation of the portable electronic device of FIG. 2, and FIG. 4 is a flow chart of a non-contact control method that can be used for charging and setting. 4, first, in Figure 2: a = preferred embodiment - portable (four) set = coupled to the transmitting unit ί42 early; ° 245. Its A 'processing unit 245 is electrically based on the Q 4 unit 243 and storage unit 244. In the middle, portable === method: know 'first, TM type to take a round ^, hair shot early 242 series use wireless side unit (four) line signal 1; continue 'in step s', sense The wireless of the measured refraction, 妒::: is received in correspondence with the output wireless signal I - and finally - in step S3, the wireless information table of the storage unit 244 causes the processing unit to be 5 in the comparison. Now I and the refracted wireless signal 244 并 并 执行 执行 四 四 钱 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 Signal worker. Alternatively, the transmitting unit 242 outputs the wireless signal in a wireless manner only when the portable electronic device 24 is in an active state, and the wireless signal output is more detailed when the user utilizes an object within the effective sensing distance. = in order to block the output of the wireless signal Ϊ the direction of travel and perform a specific direction of motion 'will cause the refracted from the object 22 wireless signal & refracted back to the sensing unit 243, and the sensing unit such as the wireless signal 11 'The wireless ray number R (for example, the difference in wavelength or intensity of the signal) refracted by the output wireless signal 1 ”, and according to the obtained alignment result, the corresponding refractory pair (10) is sought to be activated. The function, according to which the function to be activated is displayed and displayed on the screen 241. Therefore, it is not necessary to directly contact the screen 241 of the portable electronic device μ to switch the function, so that the accounting is in the process of operation 241 remains any trace to ensure aesthetics. The object 22 described above can be oriented in a direction perpendicular to the screen 241, or horizontally in the direction of the screen 241 & to perform a particular gesture or action; The portable electronic device 24 can be switched to different functions to be activated according to the distance moved by the object 22 or the amplitude of the movement. The above-mentioned function to be activated can be selected from the setting mode, the communication mode, the multimedia mode, and the data processing mode. The group of the mode and the application mode may be used by the processing unit 245 of the portable electronic device 24 to compare (eg, calculate or determine) the difference between the output wireless signal and the refracted wireless signal meter. It can also be executed by other judging elements. 200928865 In addition, the sensing unit according to different mechanisms has a corresponding operation mode. For example, when the sensing unit 243 is a microwave sensor, due to the output wireless signal I and the refraction The wireless signal R is an electromagnetic wave signal, so when the processing unit 245 compares the output wireless signal I and the refracted wireless signal R, it compares based on the wavelength relationship between the two signals. In contrast, when the sensing unit is In the photo sensor, since the output wireless signal I and the refracted wireless signal R are all optical signals, the processing unit 245 outputs the comparison. The wireless signal I and the refracted wireless signal R are compared based on the intensity relationship between the two signals. Although the above two implementations propose two different signals, regardless of the signal type, the processing unit 245, which is a difference between the wireless signal I outputted and the refracted wireless signal R, so as to find a corresponding function to be activated in the refracting table 244a, and execute the function to be activated. Therefore, the various signal types are considered to be one of the various embodiments of the present invention, and are not to be construed as limiting the scope of the invention. It is to be noted that the embodiment of the function to be activated is not limited to the invention. Please refer to FIG. 3 and FIG. 5A to FIG. 5D simultaneously, which are respectively schematic diagrams of the non-contact controlled portable electronic device of the present invention, which are corresponding to the function to be activated under different motion control within the effective sensing distance, and the applied functions thereof. The non-contact controlled portable electronic device is exemplified by microwave control. As shown in FIG. 5A, when the object 22 (for example, the user's finger) is above the screen 241 of the portable electronic device 24, it moves in a direction that is gradually closer to the screen 241 in a direction perpendicular to the screen 241 11 200928865. The object 22 performs a pressing action, so that the wireless signal I that is rotated for the screen 241 reaches the object 22, and the line from the transmitting unit 242 is "returned to the sensing unit 243, and the refraction is not The direction of the screen 241 is shifted, so that the refracted object '22 is different from the wireless signal length of the refracted wireless signal j at the wavelength close to the number R. The processing unit 245 compares the radio signal from the transmitting unit 2 Ο 〇 signal I and the refracted received from the sensing unit 243 to obtain a wireless pair of outputs to obtain a ratio of the output wireless signal to the refracted 唬R. And further searching for the wavelength function of the angle R in the refraction table 244a. For example, when the portable electronic device 24 is in a state to be activated, since the screen is pressed in the multimedia mode corresponding to the screen 241, the processing unit 245 outputs the output according to the action of the refraction (four) line signal= The wavelength of the wireless signal I is changed, and the wavelength of the ^ is determined, and the processing unit ice performs the function of "playing" in the refraction table according to the action, thereby enabling the portable electronic device to play in the multimedia mode. By performing the "press" action to perform the playback sound halfway. As shown in FIG. 5B, when the object 22 is at the sensing distance 241, that is, relative to the curtain 241, the object is gradually fascinated, so the processing unit 245 is based on the refracted wireless signal R: According to the change of the wavelength of the moving wireless signal I, it is determined that the user=long and round-out processing unit 245 performs the function of the refracting table 244='and the 'suspend' according to the action. In the multimedia 12 200928865 body mode, the action of "μ film or the like is actuated. Captain" to perform a temporary interruption to play music or as shown in Fig. 5C - V does not "when the object 22 is in the portable electronic device 24 When the hour hand rotates, the processing unit 245 determines that the user performs the clockwise rotation action by the wavelength of the wireless signal R and the output wireless signal ι, and the processing unit 245, the action is in the refraction table. In Ο 244 244a, the action 4 of "Enhancing the volume of the energy" and allowing the portable and the hour hand to rotate can be actuated in the multimedia mode by "improving the volume of the music or the movie, etc." Do not' The object 22 is moved counterclockwise from above the 241 of the portable electronic device μ, so that the processing unit 245 determines that the user performs the counterclockwise rotation according to the refracted wireless signal W wavelength and the input (four) wireless money W wavelength change. And the processing unit 245 finds the function of “reducing the volume” in the operation of the refracting table 2 according to the action, so that the portable electronic device 24 can perform the action of “reverse 8^pin, turn” in the multimedia mode. Perform actions such as lowering the volume of music or movies. Of course, in each of the above embodiments, the action of pressing, lifting, or rotating the object is taken as an example to illustrate that different actions may correspond to different functions to be activated. According to the actual demand, the invention can further subdivide the function to be activated corresponding to the action of the object by the magnitude of the pressing, lifting or rotating and the length of the action. In the case of 敎, it is also possible to align the components of the (4) to detect the rotation of the domain m movement so that signals of different degrees of movement can be switched to the corresponding functions to be activated. In addition, the above-mentioned (four) wave-only portable electronic device is exemplified by 13 200928865, and the present invention can also be a light-controlled portable electronic device according to actual needs. When the sensing unit is a light sensor, the portable electronic device can recognize the motion of the object according to the intensity of the output light wave signal and the refracted light wave signal. Further, although the above description is only made with one function to be activated, the actual action of the object on the other side can represent different functions to be activated in different function operations. For example, when the non-contact-controlled portable electronic device is in the communication mode, the user's pressing action can correspond to the "dial-out" action, and the lifting action can correspond to the "hang-up" action. When the non-contact-controlled portable electronic device is in the photo browsing mode, the user's clockwise rotation action can correspond to the "zoom in" action, and the counterclockwise rotation action can correspond to the "small" action. In summary, according to the portable electronic device and the method for non-contact control disclosed in the present invention, it is known that the sensing method replaces the touch method directly contacted by the prior art to switch different functions to be activated. Comparing the wavelength or intensity of the output Q wireless signal with the refracted wireless signal to confirm the user's action within the effective sensing distance of the portable electronic device, so that the portable device can be used to enable the portable type without touching the screen The electronic device switches between different functions to be activated. The non-contact control technology of the present invention can be widely applied to, for example, a mobile phone, a personal digital assistant or a handheld PC. This novel control design makes such frequently used portable electronic devices not cause traces of the screen. Ensure beautiful appearance and long-term use will not detract from the control function. 14 200928865 The above description is for illustrative purposes only and not as a limitation.
