HI-ZONE is an approximately 55 g, neck-worn, screenless AI Agent Wearable Platform that provides travelers with a persistent AI Tour Guide Agent across airports, streets, restaurants, museums, hotels, and destinations. Through voice, user-initiated vision, hybrid open-ear and in-ear audio, Bluetooth and Wi-Fi connectivity, and a smartphone gateway, it supports translation, navigation, cultural interpretation, dining, itinerary, and accessibility services in 20 languages without continuous screen use. CT5’s Multimodal Semantic Memory links selected places, routes, questions, preferences, actions, and outcomes into compact journey records, allowing follow-up requests to retain context. The Agent Workflow Engine coordinates specialized travel agents and returns one prioritized response. HI-ZONE supports partner-operated rental deployment through configurable trip profiles, fleet management, device reset, charging, hygiene logging, and journey-data deletion or anonymization. It evolves ZONE HSS1, a CES 2026 Innovation Awards Best of Innovation recipient in Artificial Intelligence, into an integrated device-memory-agent platform for context-aware travel assistance.
