HTC will demonstrate the first of three upcoming wearable products next week. The Taiwanese manufacturer will show a smartwatch prototype to carriers at the Mobile World Congress trade show. The source says the watch, which HTC has “no plans to show publicly” in Barcelona, will be based on Qualcomm’s Toq smartwatch, and will use that company’s Mirasol display. The source also said the HTC watch will feature Bluetooth connectivity and a music player.
