Energy Consumption and Light Interference Study for the Concept Smart Mirror
Abstract: This thesis deals with the study of how the Smart Mirror fares compared to other information oriented devices in three areas: Energy consumption, light interference from the mirror foils and general performance of the computer system. The development of Smart Mirrors has mainly been focused on usability, whilst research in performance and light interference is lacking. The project, contains composing and building a Smart Mirror which is the system all testing is performed on. The start of the thesis focuses on hardware and what choices that are possible to later describe why the mirror is designed the way as it is. It also explains the general structure of the program running the Smart Mirror and how it was built up. The programming structure shows one possible way to control the mirror and what possibilities this structure can lead to, but does not directly aect the later. The result is derived from measuring energy in Watt (W) with an energy meter and light interference in illumination with a lux meter. When it comes to the light interference tests, they mainly focus on the Smart Mirror image and viewing capabilities in a completely dark room and an illuminated room to see how the background lighting disrupts the image brightness and instead goes over to use its reecting capabilities. The outcome of the project is that the Smart Mirrors greatest obstacle to truly be a commercial device is the lower image brightness derived from the coating material. The coating material is also one of the essential components as it otherwise looses its mirroring capabilities and thus does not work as a mirror. This is also the lead cause to the high energy consumption that puts the Smart Mirror well above the normal TV and also high-performance computers.
