This invention describes a wearable fitness tracker that includes a pressure sensor, like a barometric altimeter, to measure altitude. It's specifically designed to be worn on a person's arm, forearm, hand, or finger. The device uses this altitude data for various functions, such as improving gesture recognition or managing an airplane mode.
Why it matters: Since 2015, wearable technology has become ubiquitous, and the miniaturization and integration of altimeters and other sensors for advanced activity tracking and gesture recognition are now standard. This makes the specific applications described, like altimeter-aided gesture recognition, much more feasible and powerful to implement.
