Design and Implementation of Smart Supermarket System for Vision Impaired

摘要

The visually impaired people face a lot of challenges in their routine life. One such challenge is that they have to depend completely on others for purchasing. In this paper a solution has been given to identify and purchase products in the supermarket. This system uses PIC microcontroller and RFID technology. The blind people are provided with low power RFID reader when they step into the supermarket. In the supermarket, products are segregated and placed in the shelves. Each shelf is integrated with a passive RFID tag along with unique ID which describes the category of the product and its specification. The passive tag information is read by the RFID reader and sent to microcontroller. The read tag ID is matched with recorded audio file in the APR9600 IC and played through the speaker which is embedded with the RFID reader. As the recorded audio file is unique to each product and clearly specifies about the product, they can decide about acquiring the item by listening to the audio. On implementing this method, blind people can satisfy their purchasing needs without others support.
