I. How to implement Q & A and interactivity on LED poster displays:<\/span><\/h6>\n

\uff081\uff09The LED screen is merely a display device used to present visuals, the actual intelligence, the ability to comprehend and respond, resides in an industrial, grade host computer equipped with an AI voice module, which works in tandem with sensors to trigger interactions.<\/p>\n

\uff082\uff09LED poster display \uff08visual interface\uff09+ industrial PC \uff08central processor\uff09+ data acquisition modules \uff08microphone\/camera\/touch overlay\uff09+ AI powered large scale speech recognition model.<\/p>\n

II. Interaction type of Posters:<\/span><\/h6>\n

\uff081\uff09Voice Q & A\uff08can speak and answer questions\uff09:<\/p>\n

\u2460Microphone input: a built in microphone array captures the user’s speech.<\/p>\n

\u2461ASR\uff08Automatic speech recognition\uff09\uff1aconverting speech into text.<\/p>\n

\u2462AI model processing: the host sends text to the AI, and the AI generates a response.<\/p>\n

\u2463TTS\uff08Text to speech\uff09synthesis: converts text into speech for playback via speakers, while simultaneously displaying the text or animated visuals on an LED poster screen.<\/p>\n

\uff082\uff09Touch\/Motion based interaction\uff08tap and gesture based interaction\uff09:<\/p>\n

\u2460Touch: tapping a button on the screen sends coordinates to the host unit, which then executes preset logic\uff08such as displaying an introduction or playing a video\uff09<\/p>\n

\u2461Camera\/Radar: triggered by approaching person, page turning via hand gestures.<\/p>\n

III. Why can’t conventional LED poster screens provide responses or facilitate interaction?<\/span><\/h6>\n

\uff081\uff09In terms of hardware a standard poster display consists only of a media player + LED screen.<\/p>\n

\u2460Advertising player: its function is straightforward, it simply reads images or videos\uff08from a USB flash drive or uploaded via the back end\uff09and plays them on a loop.<\/p>\n

\u2461No microphone: cannot hear people speaking.<\/p>\n

\u2462No camera\/radar\/touch frame: cannot detect someone approaching, cannot see gestures, and cannot register clicks.<\/p>\n

\u2463Without a high performance industrial PC, there is no computing power available for speech recognition or running AI based Q & A functions.<\/p>\n

\uff082\uff09At the software level: lacks interaction logic and AI capabilities.<\/p>\n

\u2460The content consists of a pre-arranged playlist.<\/p>\n

\u2461No ASR\uff08automatic recognition\uff09no AI knowledge base, and no text to speech synthesis.<\/p>\n
