Abstract:
The advance development to the innovation in the technology industries nowadays tends to evolve from a simple products to a sophisticated projects for the improvement society. In the
beginning ,the visually impaired person uses a stick to guide their way everytime when their
travelling. The stick has been always contribute the visually impaired person in improving their
mobility but unfortunately the stick has its own limitation. One of the issue that visually
impaired person for using the stick is that, it could only detect the obstacles that are within the
contact the contact ranges of the stick. This problem situation could cause the visually impaired
person to be in trouble because of insufficient time to detect and information about their
surrounding for them to react a new obstacles in front of the visually impaired person. The
main aim of “OBSVOID” is to innovate a cap to emphasize the safety of visually impaired
person when using the blind stick. From research that had been done, the visually impaired
person can only detect the the ground and the lower level obstacle. Despite that, there are many
overhead obstacle that cant be detected by the blind stick. The existing of blind stick these days
solely designed to aid the blind moving or travel by not having any safety being emphasized
while using the blind stick. The “OBSVOID” ultimate aim is to designed a prototype of the
smart cap to aid the visually impaired folks safely and emphasizing the importance safety of
the visually impaired person. The “OBSVOID” will use three ultrasonic sensors for the
detection of obstacle height in different direction and three servo motor to notify the user by
slight vibration. Therefore , we have a tendency to innovate a cap for the safety of the visually
impaired and reducing accidents involving them as well as to increase their confidence to do
their daily activities.
