At the 2015 Wearable Device Technology Expo in Tokyo in January, a tech firm introduced a small lapel worn sensor that can tell when the wearer's laughing, talking, or in trouble. Based on 10-years of "laugh-detecting" research, it's meant to help monitor the health of senior citizens. According to researchers:

To know they are "laughing" will help you see that they are happy and mentally well. "Falling" may indicate an emergency situation. This device reassures you that your loved ones, who live far away, are doing well.
