Epson, best-known for printers, is jumping into the wearable tech game. Among other things, the technology in Epson's upcoming Pulsense PS-100 wristband and PS-500 watch will monitor continuous heart rate (no chest strap required). This will enable the devices to calculate calories burned based on "personal biometrics" in addition to activity levels, age, gender and other factors, Epson claims. Epson is open-sourcing its Pulsense technology in hopes of spreading the platform via partners. The wristband features an LED and connects wirelessly to smartphone apps for reading and storing biometric data, while the watch's LCD will display heart rate and other stats. The devices can store up to 480 hours of heart-rate data, Epson says.
