Evaluating TP-Link Smart Plug: Perceived Usability and Effects on User Performance

Smart home technology has recently expanded due to advancements in wireless network sensors and mobile devices. A smart home is a home that is comprised of devices that can interact with each other and be controlled remotely via mobile applications. Smart home devices include smart bulbs, smart switches, smart plugs, smart TVs, and surveillance cameras. Employing such devices and applications could lead to some usability issues if usability is not taken into consideration during the development phase of the smart home technology. This paper investigates the usability of the TP-link smart plug and its smartphone application. The data was collected from pre- and post-test questionnaires, observation during tests, and post-test interviews. The findings show that linking the smart plug to the application was somewhat difficult, but using the smart plug was generally easy. Furthermore, recommendations were suggested to enhance the interface of the smart plug's smartphone application.
