What are various forms of corrective input or output provided by modern posture monitoring systems coupled with microcontrollers?

Subtle vibration alerts, visual feedback via a connected smartphone application, or auditory cues suggesting correction.

Contemporary posture monitoring systems leverage software and biofeedback loops to actively train users. Once microcontrollers analyze data against ergonomic thresholds, the output mechanisms are designed to provide diverse, non-intrusive forms of feedback. These outputs can range from physical sensations, such as subtle vibration alerts directly on the device, to digital communication, such as visual displays on an accompanying smartphone application that shows posture status or historical trends. Auditory cues are also employed to prompt corrective action. This variety ensures that the feedback mechanism can be tailored to the user and the context of their activity.
