Sony is introducing their new-look smartwatch 3 at CES, alongside an interesting new API and their Lifelog Web portal. As Sony is wont to do at CES, they’ve also got a rather mysterious new wearable for us. Their Smart-B Trainer prototype headset has sensors optimized for running, and is touted as a kind of motivational coach for your runs. It will also play music, and “intelligently” suggest a soundtrack for your run. Sony is also refreshing their SmartEyeglass wearable for use with any pair of glasses.
