Abstract: ABSTRACT The present invention provides an intelligent mobility-assist stick for visually impaired users based on a distributed dual-unit architecture comprising a Sensor Processing and Actuation Module (SPAM) and an Intelligent Mobile Device (IMD). The SPAM comprises multimodal sensing elements including mmWave radar, ultrasonic sensors, and infrared sensing components, coupled to an ESP32-based microcontroller configured to perform real-time obstacle detection and classification using lightweight machine-learning or TinyML algorithms. The SPAM provides immediate haptic and/or audio feedback and communicates processed obstacle, hazard, and system-status information to the IMD through a Bluetooth Low Energy (BLE) interface. The IMD functions as a communication and control hub comprising GPS, cellular and/or Wi-Fi connectivity, and a software application configured to receive BLE data, transmit location and emergency information to a cloud-based safety platform, and receive remote commands from authorized guardians. An SOS input on the SPAM generates an emergency signal that is transmitted to the IMD through BLE, enabling the IMD to acquire geographical location information and communicate an emergency notification to the cloud platform and designated guardians. The distributed architecture separates local sensing, obstacle classification, and immediate user feedback from network communication, cloud synchronization, location tracking, and remote monitoring functions. The system further supports bidirectional communication, historical movement and event logging, and remote safety monitoring for mobility assistance.
