全AI視障輔助購物裝置設計

這是一款安裝於購物推車上的智慧輔助裝置「HITUO」，旨在協助視障者於無人超市中安心且自主地完成購物。隨著無人商店逐漸普及，購物流程高度自助化，雖提升效率，卻也讓視障者在商品辨識、空間導航與結帳過程中面臨更多困難與不確定性。
HITUO整合四顆鏡頭、感測器、RFID系統與語音AI模組，提供三大核心功能。首先為避障與導航，透過距離感測與即時運算，當前方出現障礙物時，系統會以語音與震動回饋提示使用者安全移動方向。其次為商品辨識與語音播報，當商品放入推車時，系統透過RFID初步判讀，並結合影像辨識進行二次確認，即時播報商品名稱與價格，並同步顯示於螢幕上，使用者亦可透過語音互動查詢總金額或尋找特定商品區域。最後為快速結帳功能，使用者僅需透過感應手機或卡片，即可於推車上完成付款流程。
整體設計透過多重感測融合與直覺化介面，降低視覺依賴，提升購物過程中的安全性與自主性，並兼具通用設計概念，使一般顧客亦能使用，加速結帳效率，打造更友善且無障礙的智慧購物體驗。

HITUO

HITUO is a smart assistive device mounted on a shopping cart, designed to help visually impaired users shop independently in unmanned supermarkets. As retail becomes increasingly self-service, visually impaired users face challenges in navigation, product identification, and checkout.

The system integrates cameras, sensors, RFID, and voice AI to deliver three key functions: obstacle detection with voice and vibration feedback for safe navigation; product recognition through RFID and image verification with real-time audio and screen display; and seamless checkout via contactless payment directly on the cart.

By combining multi-sensory interaction and intuitive design, HITUO reduces reliance on vision and enhances safety and autonomy. It also follows universal design principles, making it accessible to all users while improving overall shopping efficiency.
