The Influence of the Perception of Visualized Data on Service Usability

With the spread of the Internet, all types of individuals come into contact with data on a daily basis and are required to correctly select, perceive, and utilize the data. In the residential environment, smart homes are accelerating, and the integrated management of devices and appliances in homes has become easier through apps and touch panels. However, in current smart home system management platforms, information is not presented appropriately for the purpose of using the system and devices. In addition, the presented data are complex, as they are a composite of data from different scales, making them difficult to perceive consistently. The presentation of Visualized Data for smart home management is often intended to promote energy and power savings. However, the “rebound effect,” where reduced energy costs lead to increased consumption, remains problematic. To address this, Visualized Data must be continuously perceived. Therefore, this research aims to classify the ease of perception of data and to examine methods of visualizing data to promote continuous perception. The survey revealed that concise and clear data with appropriate context or highlighted elements are easier to perceive.
