Wearable technology, smart textiles, IoT-based safety systems, human-computer interaction, embedded systems, and intelligent transportation in automotive engineering.
BACKGROUND OF INVENTION
Bicyclists often face challenges in signaling their intentions to motorists, especially in low-visibility conditions or at night. Traditional hand signals, while effective, may not always be noticed by drivers, increasing the risk of accidents. To address this, Gesture Control Bicycle Indicator Gloves have been developed as an innovative wearable safety solution. These gloves incorporate smart sensors and wireless communication technology to detect specific hand gestures, which then activate LED indicators on the gloves, signaling turns or stops.
Existing methodologies for bicycle indicators include manual hand signals, handlebar-mounted turn indicators, and wearable LED bands. However, these methods have limitations, such as reliance on user consistency or requiring additional installation. Gesture-controlled gloves improve upon these by offering an intuitive, hands-free signaling method. By integrating motion sensors, microcontrollers, and wireless connectivity, these gloves enhance cyclist visibility and safety, reducing accident risks while providing a seamless, user-friendly experience for urban and nighttime cycling.

SUMMARY
Gesture Control Bicycle Indicator Gloves are an innovative wearable safety solution designed to enhance cyclist visibility and communication with motorists. These smart gloves integrate motion sensors, microcontrollers, and LED indicators to detect hand gestures and automatically signal turns or stops. When a cyclist extends their hand for a turn, the embedded sensors recognize the gesture and activate corresponding LED indicators, ensuring clear and visible signaling, even in low-light conditions. Wireless connectivity can also be incorporated to sync with additional rear indicators on the bicycle for enhanced visibility.
Objective of Invention:
The primary objective is to improve road safety for cyclists by providing an intuitive, hands-free signaling system. The gloves aim to replace or supplement traditional hand signals, which are often ineffective in poor lighting or heavy traffic. By integrating gesture recognition and LED-based indicators, this invention enhances cyclist communication, reduces accident risks, and promotes safer urban commuting.

DETAILED DESCRIPTION OF INVENTION
Cycling is an eco-friendly, cost-effective, and healthy mode of transportation, but cyclists often face challenges in effectively signaling their intentions to motorists, especially in low-light conditions. Traditional hand signals may go unnoticed, increasing the risk of accidents. To address this issue, Gesture Control Bicycle Indicator Gloves offer an innovative, smart signaling solution that enhances cyclist visibility and safety.
These smart gloves are embedded with motion sensors, microcontrollers, and wireless communication modules to detect hand gestures and activate LED indicators automatically. When a cyclist tilts their hand to signal a turn or applies braking motion, the glove wirelessly communicates with an indicator unit mounted on the bicycle to illuminate corresponding lights. This hands-free, intuitive signaling method ensures clear communication between cyclists and other road users, reducing accident risks and improving road safety. With advancements in wearable technology, these gloves provide a seamless and reliable alternative to traditional signaling methods.
Purpose of the Gesture Control Bicycle Indicator Gloves
Bicycle accidents have increased due to several safety limitations in traditional bicycles, including:
• Lack of rear lights, making bicycles difficult to spot at night.
• Absence of brake lights, preventing motorists from knowing when a cyclist is slowing down.
• No built-in indicator lights for turning signals, making it hard for cyclists to communicate their movements.
To overcome these challenges, Gesture Control Bicycle Indicator Gloves integrate advanced sensors, microcontrollers, and wireless communication to improve bicycle safety. This system offers several advantages:
• Enhanced Visibility: Rear lights ensure the bicycle is visible even in low-light conditions.
• Automatic Brake Lights: Lights activate automatically when the cyclist applies brakes.
• Gesture-Based Control: Eliminates the need for buttons, allowing intuitive operation.
• Dual Brake Lights: Two rear brake lights increase visibility and safety.
• Wireless Communication: Ensures seamless interaction between gloves and indicator lights.
• Lightweight and Battery-Powered: Designed for convenience without adding bulk to the bicycle.
By addressing these issues, the system provides an effective and user-friendly solution for safer cycling.
Testing Procedures
Continuity Test
A continuity test is an essential step in electronics used to verify that an electrical circuit is complete and capable of conducting current. This test ensures there are no open circuits caused by faulty soldering, damaged components, or incorrect connections.
A small voltage is applied across the circuit, often through an LED or a buzzer. If the circuit is continuous, the LED lights up or a beep sound is heard. If not, it indicates a break in the circuit.
Steps to Perform the Continuity Test:
1. Use a multimeter set to continuity (buzzer) mode.
2. Connect the ground terminal of the multimeter to the circuit ground.
3. Place the multimeter probes across the paths that need to be tested.
4. If the circuit is intact, a beep sound confirms continuity; otherwise, no sound indicates an open circuit.
This test is crucial after soldering and hardware assembly to detect issues like broken paths, poor soldering, or handling damage.
Power-On Test
The power-on test ensures that voltage levels at different circuit points match the required specifications before connecting the microcontroller. Running this test without the microcontroller prevents potential damage due to incorrect voltage levels.
Steps to Perform the Power-On Test:
1. Set the multimeter to voltage mode.
2. Check the transformer output to confirm the expected 12V AC voltage.
3. Apply this voltage to the power supply circuit.
4. Verify that the voltage regulator receives 12V input and correctly converts it to 5V output.
5. Confirm that the 5V supply is correctly reaching the 40th pin of the microcontroller.
6. Check voltage levels at other essential terminals to ensure all connections are functioning correctly.
By ensuring proper voltage distribution, this test prevents damage to critical components and ensures the system operates reliably.
Purpose of the Gesture Control Bicycle Indicator Gloves
Bicycle accidents have become more common due to several safety limitations in traditional bicycles. Some of the key reasons include:
• Lack of rear lights – Bicycles are difficult to spot at night, increasing the risk of accidents.

• Absence of turn indicators – Cyclists have to rely on hand signals, which may not always be visible, especially in low-light conditions or heavy traffic.
To address these safety concerns, Gesture Control Bicycle Indicator Gloves provide an advanced and user-friendly solution.
