Abstract
Ergonomics awareness chairs, systems, and methods are disclosed. Methods include reading sensor values from sensors in an ergonomics awareness chair, calculating a posture type based on the sensor values, determining a time the user has been continuously sitting properly, and, if the time is greater than a predetermined threshold time, alerting the user to take a break. Systems include a user-interface computer and an ergonomics awareness chair with a controller. The ergonomics awareness chair includes a shoulder sensor, a lumbar sensor, a buttocks sensor, a thigh sensor, and an armrest sensor in each of the armrests. The controller is configured to acquire sensor values from the sensors. The user-interface computer is programmed to determine at least two types of postures based on the sensor values. The types of postures may include sitting properly and sitting improperly (e.g., slouching, hunching, straining shoulders, leaning, sitting on edge, and crossing legs).
