闇夜でほのかに光るホタルの光や秋の夜長に鳴く虫の声は、人の心を落ち着かせる効果を持っている。これらは人間の脳波や脈拍と同じ「1/ｆゆらぎ」という特別なリズムを持っていて、人を安らかな気持ちにさせる。 こうした光や音を目や耳の不自由な人たちに楽しんでもらおうと、蛍の光を「音」に、虫の声を「光」に変換して表現する研究が始まっている。
超小型電池とマイコンチップを搭載することで、本物そっくりに光る（４～５時間程度）手のひらサイズのホタルロボットが試作器として完成している。
視覚障害者に蛍の光を聞いてもらったり、聴覚障害者に鳴く虫の音を見てもらったりして、今まで障害者の方々が感じ取ることの出来なかった未知の世界を体感してもらえるようになる。目や耳の不自由な方々、あるいは日常生活の中で障害を抱えていらっしゃる方々の身近な道具として、それらの人々が日々遭遇している現代社会のストレスなどから解放されることに役立つようになる。
