Abstract

Customers tend to struggle with the large super- market settings by failing to locate products and move around the store. This may cause inefficiency and missed sales. Older methods, such as the use of fixed signs or personnel support, can have problems with natural language interpretation and offering useful information. The present paper proposes a local Large Language Model (LLM) powering conversational kiosk that can help customers in supermarkets with the help of natural voice. Customers are able to inquire about the locations of products and availability by speaking and receive clear responses as well as using text and speech.The kiosk uses the locally deployed LLM to understand customer intent and provide answers. This will minimize the use of cloud services hence lowering latency, cost and privacy concerns. The queries that customers make are compared to a pre- existing inventory database in order to locate precise aisle- level products. As well, there are simple rules of sales support, which propose complementary products in the interaction. The kiosk has a conversational robot avatar, speech synthesis, and a visual store map to enhance ease of use and interaction, which is validated by experimental observations of a customized product list and reliability in product guidance, consistency in response quality, and low response times. The findings prove the effectiveness of the local LLM-powered conversational kiosks in helping customers and providing the simplest sales support in supermarket environments.

Index Terms—Conversational kiosk, local large language models, supermarket navigation, voice-based interaction, cus- tomer assistance, in-store guidance, multimodal user interface, sales support, retail automation.
