Apple still hasnt announced plans to release an iWatch, but the evidence of one continues to mount. The iPhone maker recently patented a special type of pedometer that can locate itself on the users body, an invention that could find its way into Apples first wearable device. According to a U.S. Patent and Trademark Office filing from Mar. 13, Apples Wrist Pedometer Step Detection patent describes optimizations for detecting steps when a pedometer is worn at a users wrist. The patented technology is meant to accurately track the amount of steps a user takes, whether they wear their device around their wrist, arm or ankle.
