The assistive gloves with integrated speech output is an offline wireless system designed to store, write, rewrite, and delete data in the database, serving as a vital tool for signers to communicate with non-signers effectively. This innovative prototype is crafted with lightweight materials that collaboratively facilitate seamless translation. The system operates through several key components, each with a distinct function. The 1000mAh Li ion battery supplies power to the system. Flex sensors and accelerometers gather movement data, which is processed by the Arduino Nano microcontroller. This data is then transmitted through the nRF module, first from the left glove to the right glove. Upon receiving the data, the Bluetooth module relays the information to the Android application, which converts gestures into text or speech, facilitating communication for individuals with hearing or speech impairments. The evaluation of the assistive gloves demonstrated that the prototype successfully fulfills its intended purpose of enhancing communication between signers and non-signers. Extensive testing, including functionality, accuracy, range, and latency assessments, revealed positive outcomes. The functionality test results of the system successfully translated gestures into both English and Mandarin with 96% accuracy, alongside English speech output. Latency tests indicate a minimal delay of 0.27 seconds and maximum delay of 2.90 seconds without obstruction and minimal delay reaches 1.90 seconds and maximum delay extends to 5.10 seconds with obstruction. Optimal translation performance within less than 2 meters. In terms of functionality, aesthetics, workability, durability, safety, and economy, the project achieved an overall rating of 4.10, described as very acceptable.
