A smart band that allows you to talk with bone conduction! Developed by an engineer from Samsung [IFA 2016]

SGNL (Signal) is a young venture company spun off by Mr. Choi, who was active as an engineer at Samsung Electronics. The smart bracelet "sgnl" developed by the company is attracting attention at the Samsung booth. The device is a smartwatch, or a wearable device that replaces the wristband of a regular watch and wraps around the wrist. Pair with your smartphone via Bluetooth. The body has a built-in accelerometer and vibrator. When there is an incoming call on your smartphone, the bracelet will vibrate to let you know. This alone is not a big deal. The fun of sgnl continues. sgnl uses the principle of bone conduction to transmit the voice of a call to the human body. The basic position when using this product is to hold your index finger up when you receive a phone call and cover the ear canal with the skin on the side of the jawbone. To find out which part of the ear the skin is on, search the Internet and search for "tragus." I experienced a demonstration at the venue. When you hold your finger in the basic position, you can hear the other party's voice strangely. It wasn't the same as a normal phone call, but it was clear enough that I could hear the content of the conversation. CEO Choi gave us an interview. “The idea of ​​sgnl is that even if you wear a state-of-the-art smartwatch with a built-in microphone and speaker, you won't be able to make calls as comfortably as you would with a smartphone because the audio of conversations would be leaked out. That's why sgnl has a microphone that picks up the voice, so you can talk on the phone as if you were talking on the phone." Start fundraising on Kickstarter. The target amount was reached immediately. Since the band width can be adjusted from 18 to 24 mm, there should be many watches that can be applied.
