KTF offers a 'Love Detector' service which analyzes if someone talks with love and affection. Users can test themselves. They have to aim their mobile phone at themselves during a video conversation, see a 'love meter' bar on their screen or mobile phone, and later get a text message with the analysis. The service costs $0.32 (yh). Brands thus get better at understanding us. Not only our written language, not only our spoken words, but also the way we say them. In the end brands will be better listeners than humans. It will take at least another thirty years for that to happen though.
