Summary

Individuals with hearing impairments face significant communication barriers in the restaurant industry, limiting their employment opportunities. This study introduces HaptiServe, a haptic-based wearable system designed to enhance communication for deaf waitstaff. The system consists of an ESP32-based smartwatch, a local server, and a web-based ordering interface operating over a local Wi-Fi network without requiring internet access. Communication is handled using MQTT for device notifications and HTTP for customer orders.

Evaluation results show that the server remains stable with up to 500 users without errors. Customer connections are stable up to 55 meters, although MQTT stability depends on the router used. The device operates safely at temperatures below 30.5°C and features task synchronization to prevent duplication. The main limitation lies in battery efficiency, as deep sleep mode has not yet been implemented. Overall, HaptiServe demonstrates strong potential as a solution to improve workplace accessibility for deaf individuals.

Product Impact

HaptiServe addresses communication barriers faced by deaf workers in the restaurant industry by providing a wearable-based system that delivers real-time order notifications without relying on sound. Through the integration of haptic feedback and a local network-based ordering system, this solution enhances workforce inclusivity, improves restaurant operational efficiency, and elevates service quality for customers. Additionally, the system expands employment opportunities for individuals with hearing impairments by offering a practical, stable, and easily deployable assistive solution within FB environments.

Product Uniqueness

HaptiServe integrates an ESP32-based wearable device with a web-based ordering system, utilizing local communication through MQTT and HTTP without relying on internet connectivity. Its key advantage lies in the use of haptic feedback as the primary communication medium, along with a task synchronization feature that prevents job duplication. The system is capable of handling up to 500 users stably without errors. The local network approach also enhances security, reduces operational costs, and ensures continuous system functionality even in the absence of an internet connection.
