Posture Check
An Arduino device giving physical feedback on posture during long study sessions.
Note
Facts only for now. Full write-up to follow.
Brief
Students develop poor posture during long study sessions. On-screen alerts get ignored during focused work.
How it works
- Ultrasonic sensor measures distance between the user and their screen
- LED light cue activates when poor posture persists
- Audio alert adds a second sensory channel
Process
- Research into student study habits and ergonomics
- Sensor programming and integration
- Arduino prototype build with LEDs and speaker
- Testing with students during study sessions, adjusting sensitivity and timing
Findings
- On-screen notifications were ignored during focused work
- Early versions were too aggressive; participants said they would unplug it
- False triggers on correct posture were the main calibration problem
