Produced by the Industrial Technology Research Institute, the instrument kept a running count of the day's attendance, the number of spectators presently at the show, and the exhibit's accumulated attendance. Its one major drawback: it was prejudiced. As it turned out, bald-headed people, blondes, those wearing white hats, and children need not have applied.
這個由工業技術研究院機械所開發出來的成品，可以顯示當天的參觀人數、場內現有人數和累計參觀人數，適用於大型的會議或展覽，可惜獨獨歧視頭頂上沒有黑髮的人。
