IoT Based Smart Assistant for Blind Person and Smart Home Using the Bengali Language

Bengali is the seventh most spoken language, and 300 million people around the world speak in Bengali. The smart home is responsible for the digitization of modern society. This research reflects an Internet of Things (IoT) based smart solution, especially for the people who have a visual impairment along with the smart home. The proposed methodology presents a developed android application which will act as a smart assistant. The smart assistant is responsible for communicating with a blind person, browsing thoughts, and sharing ideas using the Bengali language. The proposed solution also focuses on the embodiment of IoT based blind stick. This article further assures a structural foundation of a smart home where blind persons and regular users will be able to control all the home appliances using Bengali voice command. This paper also illustrates experimental data analysis, such as transmission time calculation for GSM/GPRS and Bluetooth module, empirical coverage area calculation, a system usability scale (SUS), and data analysis of blind stick. We have found a SUS score of 84%. However, the proposed system will be beneficial and handy.
