Furthermore, due to the further calculation results of the optical reflection, there is often a drift, and there is a difference between the visual relationship between the user's visual observation and the size of the shielding object. If different objects such as a finger or a pen are used, there will be different effects, so the actual operation is performed. In fact, it is not easy for a user to operate a touch interface that is too high resolution; instead, a low resolution or a large graphic is suitable for a touch operation, but this does not match the current computer specifications. Therefore, the present invention discloses a technical feature that when the user approaches the screen with a finger or a pen, the area screen can sense the proximity of the finger or the pen, and the system enlarges the graphic of the area, and uses the proximity sensing to dynamically enlarge the area. Graphical interface on the screen for user convenience.

When the emitted light of the light source module 500 is reflected by the surface of the different angles and heights of the reflective component 600 to the first image capturing module 900, the first image capturing module 900 can be used to capture the second object 800. image.
第4圖及第5圖中之箭頭方向係表示物件之移動方向，當一物件800由顯示裝置200上方緩緩接近其表面，並進入反光元件600且將發光元模組500之發射光反射到第一影像擷取模組900之範圍內時，反光元件600可將發光源模組500之發射光分別反射至第一影像擷取模組900之不同高度，以使第一影像擷取模組900擷取物件800之第一影像及第二影像。其中，當物件800進入反光元件600可將發光源模組500之發射光反射至第一影像擷取模組900之範圍內時，第一影像擷取模組900依序先擷取物件800之第一影像。隨著物件800慢慢接近並碰觸到顯示裝置200之表面，第一影像擷取模組900之光源會擷取物件800之第二影像。The direction of the arrows in FIGS. 4 and 5 indicates the moving direction of the object. When an object 800 slowly approaches the surface of the display device 200, it enters the retroreflective element 600 and reflects the emitted light of the illuminating element module 500.
