IoT-Enabled Motion-Sensing Audio Playback System for Visually Impaired Individuals Using Arduino and Bluetooth Speaker

A novel Internet of Things (IoT) -enabled system is presented to improve the usability and accessibility of audio playback for those with visual impairments. To enable a simple and hands-free experience, the system uses an Arduino-based gesture-controlled Bluetooth speaker. The system uses a 9-axis accelerometer and gyroscope sensor to recognize hand motions, which are converted into order for the speaker. Using an Arduino board, which receives the gesture commands from the sensor and transmits them to the speaker using a Bluetooth module, the Bluetooth speaker is managed. Experiments assess the system's performance and show how well it detects hand movements and controls the speaker precisely and dependably. The proposed system recognizes hand motions such as play/pause, volume up/down, and track-skipping commands using an accelerometer and gyroscope sensor. An Arduino microcontroller receives the signals that have been processed, and it uses those signals to operate the Bluetooth module and speaker. The technology is precise and sensitive to hand motions, according to tests that were conducted after the prototype was developed.
