Abstract

The special need mainly visual impaired people will face difficulty to get used to surrounding environment. The current environment challenges this group, the inconvenience to adapt to their natural places could be held by new technology invented to able assist them. The ‘Development of Spectical for The Special Needs with Voice and Navigation Tools’ is mainly offering a wearable eyeglass with an ultrasonic sensor to assist the blind in comfortably navigating alone while preventing from obstacles. This project may already exist and the modification and originality on this current project are based on earlier study. This process made use of an Arduino Nano and Arduino Uno as microcontroller to control the activities of a device, ultrasonic sensors to detect an obstruction in the predefined surrounding, and an Arduino DF player module to generate voice audio. Rf module to communicate between microcontrollers. GSM is functioned to send a message to caregivers about his present location module and lastly GPS module to get real time location. This may allow the user to move more freely. This device is inexpensive, quick, and simple to use, and it is an innovation to aid the blindness and low vision in overcoming daily activities. Thus, this project implies both warning and action given to the user to ensure the safety and will be user friendly without cause any distress to circumstance surrounding it.
