Wearables Offered at Discount in Amazon Deal of the Day

Wearables made Amazon’s Deal of the Day promotion Friday at discounts of more than 20 percent. The four wearables in the bargain bin: a Lumo Lift Posture Coach and activity tracker ($49) that tracks steps taken, distance traveled and calories burned and sends gentle vibrations when slouching is sensed; a Lumo Posture Trainer ($99) that attaches to the lower back and trains a user to improve posture; and Myo gesture control armbands ($159 in black or white) that read electrical activity of muscles and arm motion to let users control technology with hand gestures.
