CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority from Indian Provisional Patent Application No. 202221060355 filed on 21/10/2022, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
The present disclosure generally relates to the detection of safety headgear of a user of a vehicle. Particularly, the present disclosure relates to a system and a method for monitoring position and orientation of a safety headgear of a user operating a vehicle.
BACKGROUND
Recently there has been a rapid development of transportation due to the increase in population and rapid development in personal mobility solutions. However, with an increase in personal mobility, the probability of accidents has also increased on the roads due to a number of reasons. Such accidents may sometimes lead to the loss of life of the user of the vehicle.
Typically, the safety of the rider of a personal mobility vehicle such as a motorcycle or scooter is always compromised due to high exposure of the rider's body. The rider safety on such vehicles is a major concern throughout the world. To enhance the safety of the riders of such vehicles, safety headgear has been introduced so as to protect the head of the rider and minimize the risk of fatal injury in case of an accident. Such safety headgear is highly effective in protecting the rider from fatal injuries in case of an accident. However, it is important for the rider to wear the safety headgear properly all the time while riding the vehicle. It has been observed that most of the riders fail to equip themselves properly with safety headgear while riding, leading to serious injuries and even fatalities during accidents. Thus, to solve the problem of riders not wearing the safety headgear, many systems have been developed to detect the presence of safety headgear near the vehicle and the rider.
However, the present safety headgear detection systems are complex and fail to detect the position of the safety headgear to ensure whether the rider has been wearing the safety headgear properly or carrying it along without properly wearing the same. Moreover, such systems also fail to continuously monitor whether the rider has been properly wearing the safety headgear throughout the journey.
Therefore, there exists a need for a mechanism to detect and monitor the safety headgear of user of the vehicle that overcomes one or more problems associated as set forth above.
