A team at MIT has created the EQ-Radio, a device capable of detecting human emotions using wireless signals. The device comes out of MIT's Computer Science and Artificial Intelligence Lab. With the EQ-Radio, which uses wireless signals to detect your heartbeat, your emotions can be detected based on changes.
When your earlier measurements are available for comparison, the system is 87% accurate. That drops to 70% when it can only use the current data set.
Just by generally knowing what human heartbeats look like in different emotional states... we can look at a random person's heartbeat and reliably detect their emotions. - Mingmin Zhao, PhD student
One of the team members, Fadel Adib, says the EQ-Radio can tell if your heart skips a beat and it could be useful in medical settings for examining arrhythmias.
By recovering measurements of the heart valves actually opening and closing at a millisecond time-scale, this system can literally detect if someone's heart skips a beat. This opens up the possibility of learning more about conditions like arrhythmia, and potentially exploring other medical applications that we haven't even thought of yet. - Adib
