     DETAILED DESCRIPTION 
       [0011]    Embodiments will be described with reference to the drawings. 
         [0012]      FIGS. 1 and 2  show a device (glasses playing device  100 ) capable of playing back or displaying electronic media files or other data according an exemplary embodiment. The glasses playing device  100  includes an eyeglass frame  10 , a left lens  20 , a right lens  30 , a processor  40 , a memory  50 , an orientation sensor  60 , and a location tracker  70 . 
         [0013]    The eyeglass frame  10  defines two receiving holes  101 . The left lens  20  and the right lens  30  are received in the receiving holes  101 . In the present embodiment, the left lens  20  and the right lens  30  are display devices, such as liquid crystal display (LCD). 
         [0014]    The processor  40  is set within the eyeglass frame  10  and is electrically connected with the left lens  20  and the right lens  30 . 
         [0015]    The memory  50  is set within the eyeglass frame  10  and is electrically connected with the processor  40 . The memory  50  stores image files and other data. In this embodiment, each image file is a picture file and includes at least one picture. In another embodiment, each image file is a video file including at least one video segment. 
         [0016]    The orientation sensor  60  is set outside the eyeglass frame  10 . In another embodiment, the orientation sensor  60  can be set within the eyeglass frame  10 . The orientation sensor  60  is electrically connected with the processor  40 . The orientation sensor  60  transmits a location detection signal to detect a preset locations information in a classroom  200 . 
         [0017]    The location tracker  70  is set individually from the eyeglass frame  10 . The location tracker  70  receives the location detection signal through a wireless network. For example, the location detection signal may be received by the location tracker  70  through a WIFI network, the location detection signals confirm a current location of the orientation sensor  60 , and such information is transmitted by the location tracker  70  via the wireless network to the orientation sensor  60 . In this embodiment, the orientation sensor  60  includes a power signal transmitter, the location tracker  70  includes a power signal detector. The location tracker  70  according to a signal intensity transmitted by the orientation sensor  60  is able to determine the current location of the orientation sensor  60 . In another embodiment, other existing techniques also can be used by the location tracker  70  to determine the current location of the orientation sensor  60 . 
         [0018]      FIGS. 3 and 4  show an operating principle of the glasses playing device  100 . For example, the glasses playing device  100  can be applied in the field of teaching, where the location tracker  70  is arranged on top of classroom  200 . A user A wears the eyeglass frame  10 , and a left eye of the user A sees the left lens  20  and a right eye of the user A sees the right lens  30 . User A wears the eyeglass frame  10  as he moves within the classroom, relocating the orientation sensor  60  to multiple preset locations in the classroom  200 , such as preset locations “a”, “b”, and “c”. Then preset locations information of the multiple preset locations are recorded in the memory  50 , such as a preset location information “1” corresponds to the preset location “a”, a preset location information “2” corresponds to the preset location “b”, and a preset location information “3” corresponds to the preset position “c”. The preset positions are preselected positions of the orientation sensor  60  within the classroom  200 . The preset location information is represented by three-dimensional coordinates in the classroom  200 . Finally, multiple image files are stored in the memory  50 , such as image file “1”, image file “2”, and image file “3”. Each image file is marked with a corresponding preset location information, such as the preset location information “1” is marked on the image file “1”, the preset location information “2” is marked on the image file “2”, and the preset location information “3” is marked on the image file 
         [0019]    When above presetting procedures are completed, the user A wears the eyeglass frame  10  and enters the classroom  200 , the orientation sensor  60  transmits signals to the location tracker  70 , and the location tracker  70  receiving the signals of a particular strength detects the current location of the orientation sensor  60 . The current location is the actual location of the orientation sensor  60  in the classroom  200 . When the current location of the orientation sensor  60  is located at the preset location “a”, the location tracker  70  detects that the orientation sensor  60  is located at the preset location “a”, and the processor  40  reads the image file “1” from the memory  50  and the image file “ 1 ” is played through the left and the right lenses  20 ,  30 , that is, the image file “1” of the preset location information “1” is selected for playback, when the current location information is determined to be the same as the preset location information “1”. 
         [0020]    Similarly, when the current location of the orientation sensor  60  is at the preset location “b”, the current location information is determined to be the same as the preset location information “2.” The processor  40  thus reads the image file “2” from the memory  50  and the image file “2” is played through the left and the right lenses  20 ,  30 . When the current location of the orientation sensor  60  is determined to be at the preset location “c,” the processor  40  reads the image file “3” from the memory  50  and the image file “3” is played through the left and the right lenses  20 ,  30 . 
         [0021]    In the present embodiment, the image file is a picture file which includes at least one picture. For example, the image files 1 and 2 include a picture P 1 , a picture P 2 , and a picture Pn. When the orientation sensor  60  is determined to be at a preset location, the left lens  20  and the right lens  30  first regularly play the corresponding first picture of the image file. For example, when the orientation sensor  60  enters the preset location “a”, the left lens  20  and the right lens  30  display the first picture P 1  of the image file “1” for a period of five seconds. If within the first five seconds, the orientation sensor  60  moves, and enters the preset location “b”, the left lens  20  and the right lens  30  are given five seconds to play the first picture P 1  of the image file “2”. If the orientation sensor  60  remains at the preset location “a” for more than five seconds, the left lens  20  and the right lens  30 , play the second picture P 2  of the image file “1” for five seconds, that is, if the orientation sensor  60  has been located in one place, then each picture is played in a sequence, until all the pictures of the image file 1 have been played. 
         [0022]    The external surface of the eyeglass frame  10  has a jitter sensor  80 , where the jitter sensor  80  can be a gyroscope. The jitter sensor  80  is electrically connected with the processor  40 . The jitter sensor  80  senses whether the eyeglass frame  10  is shaking or otherwise not steady. For example, when the orientation sensor  60  enters the preset location “a”, the left lens  20  and the right lens  30  play the first picture P 1  of the image file “1” for a period of five seconds. If within the first five seconds at the preset location “a”, the user A turns his head, then the eyeglass frame  10  consequently experiences motion, meantime, the movement is sensed by the jitter sensor  80  and a signal is transmitted to the processor  40 , the processor  40  via the left lens  20  and the right lens  30  immediately play the second picture P 2  of the image file “1” for a period of five seconds. If no motion is detected within the first five seconds, then the first picture P 1  of the image file “1” is played for the full five-second period. If motion is detected within any five-second playback period, the next picture in the sequence is played, otherwise each image in the sequence is played for the full period of five seconds, until all the pictures P 1  to Pn of the image file 1 are played. This enables the user (the viewer), simply by turning his head, to quickly move through some images he has seen before, or which are of no interest to him. 
         [0023]    When the orientation sensor  60  is located at the preset locations “b” and “c”, playing procedure of the left lens  20  and the right lens  30  is similar to that of the preset location “a.”
