Sonar Ruler vs Beacon AR

Sonar Ruler is a winner in the Best App Ever Awards - "Most innovative use of iPhone hardware" category! The Amazing New Sonar Ruler is an experimental app that uses echoes to measure distances with your iPhone! * It uses the same principles that dolphins use to find food! * It sends a short pulse from the speaker and measures how long that pulse takes to bounce off of something and return to the phone. It then estimates how far away you are. >> Impress your friends with what this unique app can accomplish using only an iphone! << Ϟ GIZMODO.com: "that's a damned neat trick for a phone to be able to do." Features: * Sonic distance measurement up to 60 feet * Set Units to feet, inches, or meters * Custom saved settings for measuring in different environments If you're a teacher, this app is a great way to teach students the principles of sonar, and how sound propagates through air. ** Watch a demo video here: http://bit.ly/sonarvideo ** German/Japanese subtitles here: http://bit.ly/sonarvid Enjoy!

Note: Use with iPads requires some adjustment to the chirp boundaries

ARにより iBeacon (location and proximity detection technology)と互換性のあるビーコン周辺の電波分布を簡単に把握できるようになりました。 次のような場面でご利用ください。 - ビーコン設置場所の検討時 - ビーコン利用アプリ開発時 ◆特徴 - 計測したい場所で画面タップすることで、ビーコンの電波強度を記録できます。 - 電波強度分布を３Dで確認できます。 - 結果はCSVや画像に出力できます。 - 面倒なUUIDの入力も、UUIDを撮影することで簡単に入力できます。 - ビーコンの上に千円札（北里柴三郎 / 野口英世の面）を置いて映すことで、ビーコンの場所として認識させることもできます。
