A System Designed to Collect Users' TV-Watching Data Using a Smart TV, Smartphones, and Smart Watches

In this study, we suggest an enhanced smart TV logging system composed of a smart TV, smartphone, and smart watch. It can be used to research the audience's complicated and segmented behaviors while watching TV. We designed a prototype of the system, which can not only detect whether viewers are located in the TV-viewing area but also measure their movements and activities by analyzing beacon signals and sensor data from the smart watch. We conducted a technical evaluation to verify its fidelity and measure its performance, and a user study identified what factors affect the users' level of engagement with the TV content. The experiment results showed that the system accurately detected and measured users' location and engagement levels while watching TV. We found that smartphone usage while watching TV is important in understanding users' TV-viewing behavior.
