3.2 Physical SoT (Satisfaction of Things)
SoT allows users to evaluate the services they have experienced with a simple hand signal toward the cameras installed at the exits of places such as tourist attraction sites, cafés/restaurants, or civil service offices. SoT investigates and collects the consumer satisfaction data by recognizing the hand motions via camera sensors, and significantly increases the user participation rates through making the evaluation process simple, interesting, and efficient. Furthermore, this real-time satisfaction survey platform can collect automatically not only the date and time and the number of visitors but gender, ages of customers through facial recognition technology.
The data collected and extracted from SoT provides various real-time data at low cost to local governments or service providers. The aggregated data sets obtained by SoT support its clients to develop effective data-based decision-making process, marketing strategies and service improvement.
