Japanese matchmaking firms get high-tech lift from gadgets and AI

Artificial intelligence and other cutting-edge technologies are starting to play a role in matchmaking as they increasingly wind their way deeper into people's lives. Today's high-tech gadgets are now being used to give people greater knowledge of potential mates, details from hobbies and smoking preferences to whether they have walked down the aisle before. At a konkatsu (marriage introduction) party held by matchmaking agency Zwei in June, participants wore wristbands. When they shook hands, their profiles would show up on a tablet computer, facilitating conversation. "Oh, I see you're a movie lover!" said one attendee, taking cues from the tablet computer.
