Hydrovoice

Nighttime hydration is essential for maintaining overall health; however, existing solutions such as bedside pitchers and traditional water dispensers fail to adequately address safety, accessibility, and sleep preservation. Users frequently navigate low-light environments, increasing the risk of spills, falls, and sleep disruption caused by bright lighting. Although modern smart-home devices provide automation and voice interaction, no current system integrates temperature-controlled water dispensing, spill prevention, and intelligent sensing into a single compact bedside unit.

The HydroVoice project aims to improve nighttime hydration by developing a multifunctional device that enables safe, hands-free access to water through voice-controlled operation and automated safety verification. The system integrates voice recognition, natural language processing, dual-camera sensing, and temperature regulation to detect cup placement, monitor fill levels, and ensure safe dispensing conditions before water is released. Additional features include ambient LED lighting for low-visibility environments and a touchscreen human-machine interface that allows manual control and system monitoring.

The resulting prototype is designed to enhance user safety, improve accessibility for individuals with mobility limitations, and minimize sleep disruption while demonstrating a scalable approach to intelligent hydration technology. By combining automation, sensing, and user-centered design, HydroVoice establishes a foundation for next-generation smart bedside appliances.
