2 枚の板状のゲルに挟むことで取り付けた．ユーザのゲル上での操作に伴うゲルの形状変化により，超音波の伝播特性は変化する．この変化を利用して，ゲル表面への押し込み動作の押下位置・圧力を同時に認識する．本研究では，ゲルに超音波を送受信するプロトタイプを実装し，押下ごとの押下圧力を一定に保つ機械を用いて正確にゲル上 4 箇所でそれぞれ 200g から 1000g を 200g ごとに圧力をかけて認識を行い，提案手法の性能を調査した．評価の結果，認識精度は 69.3% であることを確認した．このデータのうち，200g，600g，1000g のデータのみを用いて認識を行った結果，認識精度は 88.8% であり，誤認識が少ないことが確認できたため，5 人の被験者を対象に同様の実験を行った．学習データに機械による実験のデータ，テストデータに被験者それぞれの実験データを使用したところ，認識精度は平均で 62.1%
