english: So we joined forces with Georgia Tech, with Thad Starner's wearable computing group, to build us an underwater wearable computer that we're calling CHAT. [CHAT: Cetacean Hearing And Telemetry] Now, instead of pushing a keyboard through the water, the diver's wearing the complete system, and it's acoustic only, so basically the diver activates the sounds on a keypad on the forearm, the sounds go out through an underwater speaker, if a dolphin mimics the whistle or a human plays the whistle, the sounds come in and are localized by two hydrophones.

[CHAT: Cetacean Hearing And Telemetry] Sada umesto guranja tastature kroz vodu, ronioci obuku kompletan sistem, koji je samo akustičan, pa kada ronilac aktivira zvuk na maloj tastaturi na podlaktici, zvuci izlaze kroz podvodni zvučnik, ako delfin imitira zvižduk, ili ako ljudi puste zvižduk, zvuci ulaze i lokalizuju se pomoću dva hidrofona.
