     DETAILED DESCRIPTION OF THE INVENTION 
       [0016]    Please refer to  FIG. 1 .  FIG. 1  is a block diagram of a portable LED interactive learning device according to an embodiment of the present invention. The portable LED interactive learning device  100  in the present invention includes a motion detecting device  110 , a tilt detecting device  120 , a micro processer  130 , a LED set  140 , a memory  150 , and a input module  160 . The motion detecting device  110  and the tilt detecting device  120  are utilized for detecting and receiving the user&#39;s motion control or order. The micro processer  130  will receive the control signals from both the motion detecting device  110  and the tilt detecting device  120 , and send a display signal to the LED set  140  based on the user&#39;s motion. The LED set  140  is utilized for displaying any learning or game contents according the display signal. The memory  150  can be utilized for storing the display and interactive record or the game contents. The input module  160  can receive outside input source, such as flash drive or hard disk, to extend the capacity of the memory  150 . The fully operation of the portable LED interactive learning device  100  in the present invention is detailed as follows. 
         [0017]    First, the motion detecting device  110  will detect any motion or action derived from the user&#39;s gesture. Please refer to  FIG. 2 .  FIG. 2  is a block diagram of the motion detecting device  110  according to an embodiment of the present invention. The motion detecting device  110  further includes a motion sensor  112  and a control sensor module  114 . The motion sensor  112  is utilized for detecting the user&#39;s gesture. For example, when the user sweeps his finger form right to left above the motion sensor  112  to draw a horizontal line, the motion sensor  112  will generate a motion signal S M  based on the user&#39;s sweep. The LED set  140 , latter proceeds by the micro process  130 , will display a corresponding horizontal line according to the motion signal S M . Moreover, the control sensor module  114  is utilized as function selection controls. There are many types of function selections for game and learning purpose, such as store, reset, start, forward or backward. The user can setup the desire function at will. For instance, in one embodiment of the present invention, the user can setup an order by placing his finger above the control sensor module  114  for at least 3 seconds as a “store” function. And the control sensor module  114  will generate a corresponding control signal S C  based on the above motion order. 
         [0018]    In practice, the motion sensor  112  and the control sensor module  114  can be implemented by infrared photography (IR) sensors, gyro sensors, phototransistors, photo-resistors or other photosensitive devices. And we are going to use IR sensors to illustrate the embodiment of the present invention. The IR sensors comprise a pair of IR photodiodes and IR emitters. The IR photodiodes and the IR emitters can be received and emitted at the same time. Therefore, the user only needs to slightly touch or sweep thumb above the IR sensors and the motion sensor  112  and the control sensor module  114  can be thereby enacted. The advantage of using IR sensors is that they are much cheaper than touch panels, and the user does not really need to push the buttons to manipulate the device and play games. However, as will be easily observed by a personal of ordinary skill in the art, other embodiments of the present disclosure utilizing different types of sensor devices are also possible, and the use of IR sensors is not meant to be taken as limitations. 
         [0019]    Next, the tilt detecting device  120  is utilized for detecting tilt condition of the device and generating a tile signal S T  based on the tilt condition. Similar as the control sensor module  114 , the tilt detecting device  120  in the present invention can be utilized as function selection controls, such as a navigation function. For example, if the user wants to see next figures, they can tilt the device forward and backward to see the previous figures. Moreover, the tilt detecting device  120  can also be used to detect the shake movement of the device, which can create more movement selections for the user to control the interactive device in the present invention. In practice, the tilt detecting device  120  can be implemented by a jiggle switch, G-sensor or other tilting detecting units. Same, the use of the jiggle switch or G-sensor is not meant to be taken as limitations. 
         [0020]    After receiving the motion signal S M , the control signal S C , or tilt signal S T  from the motion sensor  112 , the control sensor module  114 , or the tilt detecting device  120 , the micro processor will proceed these signals and generate a display signal S D  to LED set  140  to display corresponding figures. In one embodiment of the present invention, the LED set  140  is consisting of 108 LEDs to form a 5″ display matrix. Please note that, the present invention id not limited to the color selection of LEDs. That is, the LED set  140  can be embodied by different colors, such as red, green, or blue, depending on different design requirements. Comparing with other display device (e.g. LED display, OLED display, TFT LCD, OLED display or TN type LCD display), the usage of LEDs in the present invention thereby significantly reduces the display cost, which can create more convenience and affordable device for kid&#39;s education development. 
         [0021]    The memory  150  can be utilized for storing the game contents or the user&#39;s interactive record. The input module  160  can receive outside input source, such as cartridge, flash drive, or hard disk, to provide more contents or games, and extend the capacity of the memory  150 . Here, the input module  160  can be embodied by a cartridge slot, or a USB interface slot. Moreover, the portable LED interactive learning device  100  in the present invention can further include a build-in audio system (not shown) to play back the sound effect and music during the game playing, which can increase more interactive attraction for kids. 
         [0022]    Please refer to  FIG. 3 .  FIG. 3  is a flowchart showing an operation of a portable LED interactive learning device according to an embodiment of the present invention. Provided that substantially the same result is achieved, the steps of the flowchart shown in  FIG. 3  need not be in the exact order shown and need not be contiguous, that is, other steps can be intermediate. As shown in  FIG. 3 , the user&#39;s function order (e.g. start, reset, or replay function) will be detected by the portable LED interactive learning device based user&#39;s motion (Step  301 ). After receiving the order from the motion detecting device, the micro processer will perform the function order on LED set based on the receiving order (Step  302 ). Next, user&#39;s gesture will be detected to determine the figure which the user desires to draw (Step  303 ). Then the figure will be display on the LED set based on the detected gesture (Step  304 ). Moreover, the tilt condition of the device will be detected by the tilt detecting device (Step  305 ), and the corresponding navigation function will be performed on LED set based on the receiving tilt condition (Step  306 ). Last, the playing information or game data can be saved and stored in the memory, or stored in outside memory devices through the input module (Step  307 ). 
         [0023]    Please refer to  FIG. 4  and  FIG. 5 ,  FIG. 4  is diagram schematically showing a deployment of portable LED interactive learning device according to an embodiment of the present invention. As shown in  FIG. 4 , the motion sensor  112  can be located in the middle of LED set matrix in order to detect the user&#39;s movement. And the control sensor module  114  can be located at the right and left bottom corners of the LED set matrix, which the user can use the control sensor easily. As shown in  FIG. 5 , the portable LED interactive learning device can display any figure or letter (as shown “M” letter in  FIG. 5 ) based on the users movement. Along with the tilt detecting module, the portable LED interactive learning device can create more functional abilities for user&#39;s selection. 
         [0024]    Another embodiment of the present invention is showing in  FIG. 6 . The portable LED interactive learning device can be association with real time clock or alarm clock. The user can be able to look at the real time through the portable LED interactive learning device  100  and to set the stand-up time. As shown in  FIG. 6 , the portable LED interactive learning device display the time 9:17, and when the real time clock or alarm clock rings, the user only needs to swing their hand a few times in front of the unit to shut off the ring. In contrast to the related art interactive device, the portable LED interactive learning device in the present invention utilizes sensor detectors to detect user&#39;s movement. The user does not really need to push any buttons to manipulate the device and play games. He only needs to slightly touch or sweep thumb above the detecting device to play on the screen. Moreover, the portable LED interactive learning device in the present invention utilizes LED set as a display mean, which significantly reduces the display cost, and creates more convenience and affordable device for kid&#39;s education development.
