Introduction

In recent years, assistive technologies have made significant strides in empowering individuals with disabilities, particularly those with speech and hearing impairments. One such innovation is the Smart Glove, a wearable electronic system designed to bridge the communication gap by translating hand gestures into readable text and audible speech. With the increasing demand for accessible communication tools, this project combines Arduino, flex sensors, an accelerometer, and Bluetooth connectivity to create a real-time gesture interpretation system.

The glove is embedded with three flex sensors, one on each of the index, middle, and ring fingers, to measure finger bends. An accelerometer detects hand orientation and motion. These inputs are processed by an Arduino UNO, which maps each gesture to a predefined word or phrase. The interpreted gesture is sent via Bluetooth to a mobile phone or PC, where it is displayed as text and converted into speech using a text-to-speech engine.

The Smart Glove is a powerful example of human-computer interaction, enabling users to communicate efficiently without verbal input. It offers a portable, affordable, and practical solution for real-time interaction.

Project Methodology: Smart Glove for Gesture-to-Speech

The development of the Smart Glove follows a structured engineering approach, divided into hardware interfacing, signal processing, and wireless communication.

1. Hardware Assembly & Interfacing

The first phase involves mounting the sensors onto a wearable fabric (the glove) and creating the electrical connections:

• Flex Sensors: Integrated onto the fingers. Each sensor is connected in a Voltage Divider configuration with a $10k\Omega$ resistor to convert resistance changes into measurable analog voltage.
• ADXL335 Accelerometer: Mounted on the back of the hand to track 3-axis ($X,Y,Z$) movement.
• Microcontroller: The Arduino Nano acts as the central hub, receiving analog inputs from the sensors via its ADC (Analog-to-Digital Converter) pins.

2. Data Acquisition & Calibration

Since every hand and glove fit is different, a calibration phase is necessary:

• Baseline Mapping: The system records voltage values for a “Neutral” hand position.
• Threshold Setting: Specific voltage ranges are defined for “Bent” vs. “Straight” fingers.
• Orientation Mapping: The accelerometer values are mapped to determine if the hand is flat, vertical, or tilted.

3. Gesture Recognition Logic

The Arduino runs a firmware script that continuously polls the sensors:

• Pattern Matching: The code compares the real-time sensor data against a pre-stored truth table of gestures.
• Logic Example: IF (Index Flex > Threshold) AND (Middle Flex > Threshold) AND (Tilt = 0), THEN Gesture = “Peace”.
• Data Packaging: Once a match is confirmed, the corresponding string (e.g., “I am hungry”) is prepared for transmission.

4. Wireless Transmission

• The HC-05/06 Bluetooth Module establishes a serial link with a smartphone.
• The recognized text is sent as a data packet using the UART protocol (Universal Asynchronous Receiver-Transmitter).

5. Mobile Application & Output

The final stage occurs on an Android device:

• Bluetooth Reception: The app listens for incoming strings from the glove.
• Text Rendering: The received string is displayed on the mobile UI.
• Speech Synthesis: The app triggers the smartphone’s built-in Text-to-Speech (TTS) engine to announce the gesture out loud, enabling audible communication for the user.
