The first way is to seek help from the teachers of the Creative Technology Lab. One solution provided by the teacher is to use a laser and equip a laser receiver on the top to determine the position of the audience. But the teacher also pointed out that there is a problem that the audience needs to be equipped with a laser on their feet after entering the venue. As a result, this option becomes less feasible. So I thought of the workshop about Arduino I attended here in my freshman year. I knowed that the only sensor offerd in our school is Arduino, and schools offer courses on Arduino and that distance-aware parts are available. So in order to specifically detect the position of the audience, I proposed a plan to use two Ardunio distance sensors, and got a positive reply from the teacher about the feasibility. But the specific operation remains to be studied in depth.
