To Hye-ryeong Yoon, a barista with hearing impairment, who strives to live like ordinary people by learning to communicate, IoT has brought small but big changes. We intended to sincerely deliver the usefulness and value IoT service can bring people based on the story of her. We captured the everyday life of Yoon living on her own, who always needed mother’s help, without depending on others with the help of the technology. We also included the surprise event of her expressing appreciation to her mother in the video. Although the story does not feature famous models, nor it does have any dramatic content, we believed that a story of ordinary people we can see around us and story about families can give deep impression. To maximize the immersion of story and induce bond of sympathy, we produced the video in a format similar to a documentary while minimizing brand exposure.
