ウルトラハットの知名度

Posted at 2019-12-25

皆さんメリークリスマス！（遅くなってごめんなさい）
この記事はIoTLT Advent Calendar 2019の12/24記事です。

IoTLT仙台やってるひろみちゃんこと櫻井です。

今年はめちゃくちゃ忙しくて参加するのどうしようかなと思ってたんですが思わず枠取っちゃったんですよね。
それでも後の方に後の方にと23日にしたのに遅れるという。申し訳ございません。

んで何書こうか迷ったんですが、先日イベントの為に作成した（してもらった）ウルトラハットについて書こうかと。

職業柄展示会に参加する事が多いんですが、内容によっては一人で対応する事もあるんですよね。
でもステージとかで聞きたい講演とかあるじゃないですか。
そんな時、こんなんあればいいなって思ったのがファミレスとか居酒屋にあるアレ↓

これ押してくれたら戻りますって感じにしたらIoTっぽいしいいんじゃないかと。
でも、普通に作っても面白くないので、いろいろ考えてみたんです。

皆さんアメリカ横断ウルトラクイズって知ってますかね？

子供ながらに見てた番組でしたが、福留さんの決め台詞「ニューヨークへ行きたいかー！？」が今でも忘れられません。
ゲームボーイでゲームソフト化もされ、自分もお年玉で買いました。
そんな国民的クイズ番組ですが、その中の早押しクイズなどで使用されていた回答権を解り易く表示する仕組がウルトラハットです。

これ見たらワクワクしますよね？
なんなら講演聞いてる人達も気になって声かけてくれるかも！
