![]() These mirrors are usually able to display general information such as news, weather, time, calendar, reminder, and alarms. General-purpose smart mirrors are those built exclusively for everyday use. Based on the field of use, smart mirrors can be classified into: general purpose, medical, fashion, and hotel. With time, the concept of smart mirror evolved, and nowadays, it is easy to create a smart mirror with those basic features as more specialized types of smart mirrors started to emerge. Those mirrors, using a reflective screen, were able to display not only general information such as weather, news, and email, but also personal data like calorie consumption, heart rate, steps, etc., obtained from connected devices. In the same year that Magic Mirror was released, Toshiba presented their own concept of a “smart mirror” at CES. The original project moved forward with a second version of the Magic Mirror (MagicMirror 2- (accessed on 15 October 2021)). Even though it started as a “Do It Yourself” (DIY) project around 2013–2014, the first known smart mirror was built by Michael Teeuw back in 2014 using a Raspberry Pi 2 (MagicMirror- (accessed on 15 October 2021)). The idea of a smart mirror is not something new, and the conception of this idea dates back to the late 1990s and early 2000s with science-fiction movies. Thus, it seems obvious to transform a normal mirror into a smart mirror with the capabilities of detecting and helping the user emotionally, both in the short- and long-term. Whether it’s stationed in the living room, bedroom, or bathroom, a mirror is something that most people use everyday. Nowadays, a mirror is a common object that everyone owns. A good solution is to transform an object that everyone owns such as a mirror and use it for monitoring the user’s emotions and, at the same time, offer features for emotional support in a smart way. Monitoring those emotions can be really challenging since it is uncommon to own a specific device for that kind of purpose. ![]() The problem is when those changes end up negatively, resulting in lower productivity and possibly impacting relationships such as a lover, work colleague, or friend. Sometimes it’s possible to see those changes in a matter of days or even hours. People’s emotions can change a lot in a short span of time. The effectiveness of the device is demonstrated by the performances of the implemented functionalities, and the evaluation in terms of its usability with real users. We exploit a deep learning technique to develop most of the smart functionalities. Among the advanced functionalities are the capabilities of detecting a person’s emotions, the short- and long-term monitoring and analysis of the emotions, a double authentication protocol to preserve the privacy, and the integration of Alexa Skills to extend the applications of the smart mirrors. In this paper, we present a general-purpose smart mirror that integrates several functionalities, standard and advanced, to support users in their everyday life. General purpose smart mirrors are suitable for home environments but the exiting ones offer similar, limited functionalities. Different kinds of smart mirrors exist: general purpose, medical, fashion, and other task specific ones. Smart mirrors are devices that can display any kind of information and can interact with the user using touch and voice commands.
