A prototype of a smart gesture-controlled mirror with enhanced interactivity is proposed and designed in this paper. With the help of hand gestures, the mirror provides some basic amenities like time, news, weather etc. The designed system uses Pi cam for image acquisition to perform the functions like gesture recognition and an ultrasonic sensor for presence detection. This paper also discusses the experimental analysis of human gesture interaction using parameters like the angle which ranges its horizon from 0 to 37 degree when tilting the forearm up and down and 0 to 15 degrees when the forearm is twisted right to left and otherwise based on yellow, pink and white background colours. Additionally, the range of detection using an ultrasonic sensor is restricted to the active region of 69.6 to 112.5 degrees. Moreover, time delay which takes half a second for a time as retrieve with the system and take 6 to 10 seconds for fetching headlines and weather information from the internet. These analyses are taken into account to subsequently improve the design algorithm of the gesture-controlled smart mirror. The framework developed comprises of three different gesture defects under which mirror will display the mentioned information on its screen.
