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.
