Bringing underwater messaging to smartphones
Researchers in the University of Washington's Paul G. Allen School of Computer Science & Engineering introduce AquaApp, the first software-only solution for underwater communication and networking on smartphones. AquaApp is an acoustic system that leverages the device's built-in speaker and microphone to send and receive messages in a variety of underwater conditions without any special hardware required. The open-source code is available to download for Android devices at https://underwatermessaging.cs.washin....
