The present invention discloses a low-cost and student-oriented solution for enhancing posture and combating drowsiness during long study periods. With simplicity and usability in mind, the system is integrated into a standard study chair with ease and utilizes low-cost electronic devices like pressure sensors (2), a tilt sensor (3), and a vibration motor (4) to establish a smart feedback system promoting correct posture and vigilance. The system works by constantly observing the seating activity of the user. Pressure sensors (2) embedded within the seat and backrest measure the presence and posture of the user, while a tilt sensor (3) built into the headrest monitors forward head movement, which is an early indication of drowsiness or distraction. Whenever the system perceives slouching, extended inactivity, or excessive head nodding over a predefined threshold angle, it initiates a subtle vibration motor (4) integrated into the chair. Unlike wearable solutions that may be uncomfortable or intrusive, the chair-based system provides a non-invasive experience. It does not intrude into the user's space but rather integrates smoothly into their surroundings without the need for them to wear a device or alter their usual study habits. Basic sensors and a microcontroller making the design low cost and easy to build make it suitable for students, teachers, or hobbyists looking for health-oriented innovations. Further, this intelligent study chair (1) can be modified for purposes of usage in schools, libraries, coaching institutions, or even home study rooms. By dealing with both posture and sleepiness within an integrated system, not only does it enhance physical health but also mental concentration. Overall, this project describes a new yet practical methodology for enhancing study habits through intelligent furniture design providing comfort and productivity in an intelligent, easy-to-use configuration.
