You may not have given much thought to being able to text underwater, but for millions of scuba diving and snorkeling enthusiasts, communication in the ocean is pretty essential to staying safe.
Right now, hand gestures are the preferred way of keeping in touch under the waves, and professional divers use a globally recognized vocabulary of more than 200 of them .With those limitations in mind, researchers have developed a special smartphone app that uses acoustic signals to enable people to stay in touch underwater.from the University of Washington in Seattle.
"Other than downloading an app to their phone, the only thing people will need is a waterproof phone case rated for the depth of their dive,"That app is AquaApp, and it can work with speakers and microphones on ordinary smartphones – or even smartwatches. It gives users 240 preset messages to pick from, split into eight categories for easier access.
On top of that, smartphones and smartwatches used to send and receive messages are likely to be always shifting position under the water. The app does this through a 'preamble' that establishes contact between two devices. Having established the best conditions for messaging, the communication can then be sent, overcoming obstacles like motion and reflection.
