From Touch to Voice: The Role of Smart Devices in Enhancing Navigation and Interaction for the Visually Impaired

Smart devices integrate haptic feedback and voice interaction technologies to provide innovative solutions for navigation and information interaction for the visually impaired. This paper explains the fundamental principles of core technologies such as sensors, voice recognition, and haptic feedback, as well as the architecture of auxiliary navigation systems. It analyzes the integration patterns and optimization strategies of haptic and voice interaction, and explores the challenges faced by current technologies in terms of recognition accuracy, latency, and battery life through practical applications such as outdoor and indoor navigation. The paper also proposes targeted improvement measures to provide technical references for enhancing the efficiency of navigation and interaction experiences for the visually impaired.
