大型免許・二種免許で必要な「深視力」(三桿法)の感覚を、スマホで手軽にトレーニングできるアプリです。 三桿法の動きをシンプルに再現し、中央のラインがそろうタイミングを見極める練習ができます。 ■ 使い方 開始位置を選ぶ(奥 / 手前 / ランダム)  ・奥・手前:端からの練習向け  ・ランダム:実際の検査に近く、開始位置(中央から何cmか)が分からない状態で開始 スタートで練習開始(1回押すだけ) 中央のラインの濃さ・太さが変化(棒は動き続けます) 「3本がそろった」と感じた瞬間にストップ(これを3回) 各回の誤差は「手前」「奥」の方向と距離(cm)で表示 3回の平均誤差が 2cm以下 なら合格の目安 奥・手前モードでは、開始から約3秒で揃うリズムをつかみやすいのが合格のコツです。ランダムモードでは、実機と同じく“わからない位置から見極める”感覚を鍛えられます。 ■ 注意事項 本アプリは訓練・予習用のシミュレーションです。 実際の深視力検査の結果や、免許の取得・更新を保証するものではありません。ご了承ください。
