Abstract:
Visually impaired is someone’s condition of
lacking visual observation due to neurological and physiological
factors. Also, wildfire and coronavirus cases made the situation
worst for visually impaired people. A helping tool is very needed
to overcome these problems. This paper proposes a prototype of
an embedded glove using ultrasonic and flame sensors to
provide a convenient and safe method for visually impaired
people to overcome difficulties in daily life. Smart glove system
prototype based on Arduino UNO microcontroller, ultrasonic
and flame sensors, SIM800L GSM module for communication,
and buzzer for alarm notification. Then, the complete device
prototype was tested using both the acrylic box and embedded
at one’s hand as a proof of concept for emphasizing the
reliability and usefulness of our work. The results show that the
ultrasonic sensor works well for detecting an object with a
coverage of 40 cm from the blind. The fire/flame sensor also
works well when using fire detection mode for detecting the
small fire from matches or lighter at a distance of about 15 cm
or big fire from a burnt paper at a distance of about 20 cm and
will be sending a short message to the respected person through
SIM800L GSM. The only drawback for this device is a bit heavy
when used on hand and still lacks an IoT system. However,
further research will be conducted to overcome those problems
soon.
