| 摘要 |
The present invention provides an educational or entertainment system capable of activating audio, web-based streaming or flash video presentations from designated portions of a printed surface containing visual images, comprising a surface containing a plurality of discrete, visually colored zones which code for particular presentations, each of said colored zones being overlaid by or surrounded by a zone of invisible fluorescent substance which can be detected by the use of light outside the visible spectrum and means for detecting the same. The system further includes a portable reader comprising: (i) a sensor pipe, (ii) a means for directing a first beam of light within the visible spectrum, located within the sensor pipe and a means for directing a second beam of light, also within the visible spectrum, located within the sensor pipe, (iii) a detector for detecting light emanating from said invisible fluorescent substance when light outside the visible spectrum impinges upon it and for detecting light reflected from the visually colored zones, (iv) a means activated by the detector when light emanating from said invisible substance is detected which causes the reader to emit said second beam of light, and (v) means for playing audio, web-based or flash video presentations coded by the visually colored zones when light of a particular wavelength within the visible spectrum is reflected from a visually colored zone and detected.
