多功能化要求攜帶型電子裝置具有較大屏幕，而輕薄短小之要求則使得攜帶型電子裝置很難有太大之屏幕，如此具有投影輸出功能之攜帶型電子裝置應運而生。即，於攜帶型電子裝置上安裝有投影輸出裝置，從而將攜帶型電子裝置之相關資訊由投影顯現出來，如此則不必受到攜帶型電子裝置自有顯示幕尺寸大小之限制。The multi-functional portable electronic device has a large screen, and the requirement of being thin and light makes it difficult for the portable electronic device to have a large screen, so that a portable electronic device having a projection output function emerges. That is, the projection output device is mounted on the portable electronic device, so that the related information of the portable electronic device is visualized, so that it is not limited by the size of the display screen of the portable electronic device.
惟，使用者於操作攜帶型電子裝置之按鍵時必然要產生攜帶型電子裝置之晃動，如此攜帶型電子裝置輸出之投影也跟著晃動，非常不利於觀看，從而限制了具有投影輸出功能之攜帶型電子裝置之應用。However, when the user operates the button of the portable electronic device, the shaking of the portable electronic device must be generated, so that the output of the portable electronic device is also shaken, which is very unfavorable for viewing, thereby limiting the portable type with the projection output function. The application of electronic devices.
有鑒於此，有必要提供一種具有穩定投影之攜帶型電子裝置。In view of the above, it is necessary to provide a portable electronic device having a stable projection.
一種攜帶型電子裝置，包括一鍵盤投射模組、一紅外線發生器及一紅外線感應模組，該鍵盤投射模組用於投射鍵盤圖形，該紅外線發生器用於投射與鍵盤圖形平行之紅 外線，當使用者操作鍵盤圖形時，該紅外線感應模組用於接收被使用者之手指反射之紅外線以得出使用者所按下之鍵值。A portable electronic device includes a keyboard projection module, an infrared generator and an infrared sensor module, wherein the keyboard projection module is used for projecting a keyboard graphic, and the infrared generator is used for projecting a red parallel with the keyboard graphic. In the outer line, when the user operates the keyboard graphic, the infrared sensing module is configured to receive the infrared light reflected by the user's finger to obtain the key value pressed by the user.
相較於習知技術，所述攜帶型電子裝置藉由鍵盤投射模組投射之鍵盤圖形來代替傳統之按鍵鍵盤，使得人們不用觸動攜帶型電子裝置就能進行資訊之輸入，如此攜帶型電子裝置則能輸出穩定之投影而利於觀看。Compared with the prior art, the portable electronic device replaces the traditional keyboard keyboard by the keyboard graphic projected by the keyboard projection module, so that people can input information without touching the portable electronic device, such a portable electronic device. It can output a stable projection for viewing.
