Glove Sign is a portable prototype that translates one-hand gestures into characters/messages to support communication for people with speech impairments. The system uses a stretchable glove with five 2.2" bend sensors (one per finger), an on-board IMU (accelerometer + gyroscope) on Arduino Portenta, portable power, and an LCD1602 I2C display for instant feedback.

    Sensor data are filtered and normalized; then a recognition algorithm maps finger postures and hand orientation to letters or simple commands. The output is shown locally on the display and can be forwarded to a software dashboard for logging.
