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). |

1. A method of promoting ergonomic posture of a user sitting in an ergonomics awareness chair, the method comprising:
reading a first sensor value from a first sensor of the ergonomics awareness chair and a second sensor value from a second sensor of the ergonomics awareness chair; calculating a posture type based on the first sensor value and the second sensor value, wherein the posture type is one of proper sitting posture and improper sitting posture; determining a time the user has been in the posture type; alerting the user of improper posture if the posture type is the improper sitting posture and the time is greater than a predetermined threshold time; alerting the user to take a break from sitting in the ergonomics awareness chair if the posture type is the proper sitting posture and the time is greater than a predetermined break interval; and repeating the reading, the calculating, the determining, the alerting the user of improper posture, and the alerting the user to take the break until the user is alerted to take the break. |
