A system that can read your hidden excitement, happiness, anger, or sadness. With or without your cooperation?

It’s called “EQ-Radio,” and it’s the creation of MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL).

MIT Develops Tech that Can Read Your Inner Emotions, Accurately, From a Distance

They claim it’s accurate 87% of the time. It reads your feelings by bouncing ordinary WiFi signals off of you that can track your heart rate. There are no on-skin sensors involved with EQ-Radio.

How EQ-Radio Works

WiFi is a two-way form of communication: Your router carries internet data to your laptop, which then transmits data back to the router en route to the internet.

An EQ-Radio measures the speed at which data completes a round trip to its target — for example, you — and analyzes fluctuations in that speed to measure your heart rate. It’s your heart rate that gives away your emotional state. (Is there Not a wide array of emotions?)

The correlation of heartbeat to emotion in each person is unique to some extent, but MIT says they can accurately assess the emotional state even of people they’ve never before studied 70% of the time.

Mingmin Zhao, on the MIT team, told MIT News, “Just by knowing how people breathe and how their hearts beat in different emotional states, we can look at a random person’s heartbeat and reliably detect their emotions.”

One of the challenges the team faced was filtering out extraneous “noise” such as breath sounds to clearly detect the heart rate.

Bear in mind that it’s not audio that EQ-Radio has to analyze, but instead data that reflects the speed of the WiFi bounceback.

So “noise” refers to irrelevant data, not the actual sound of, say, your breath. That they’re able to measure heart rate with about a .3% margin of error is remarkable. That’s as good as an ECG monitor.

The EQ-Radio software is based on previous work the lab has done using WiFi to detect human movement. The goal of the earlier work was to use WiFi in smart homes that could do things like control heat and lighting based on your location, and detect if an elderly person has fallen. (It’s also seen as having potential use for animation motion-capture in films.)

The junction of that earlier project and EQ-Radio was the exploration of more-accurate health-tracking wearable devices.

The Possible Uses of EQ-Radio

There are a number of obvious applications for EQ-Radio, such as:

• Far more accurate test screenings and focus groups for ad agencies and film studios
• Smart homes that can adjust lighting and environmental controls to match, or help you out of, your mood
• Smart hotels that could continually customize a guest’s environment according to mood
• Non-invasive healthcare and psychiatric monitoring, with office or home-installed systems
• Directed advertising based on an assessment of a target’s mood
• Interrogations

Hopefully, EQ-Radio won’t turn up in personal devices that let you “read” the emotions of people around you.

(And after all these emotional diagnosis? How are our health to be treated? By EQ-Radio also? Can the people receive any feedback? Is this a one-way technique to accumulate meta data for ad. agencies?)

EQ-Radio and Privacy

When EQ-Radio moves beyond its current laboratory setting, there’ll be obvious privacy concerns: Do you have the right to keep your feelings to yourself? (Are you kidding?)

If you’re in a public place — say, a hospital or theater — where an EQ-Radio system is in operation, will a signed release from you be required before your emotional state can be tracked?

Would you have to give a police department permission to monitor your feelings during an investigation, or could you refuse as you can a polygraph test?

Could an authoritarian government “read” its citizenry at will?

Will this become a standard tool to anti-terrorism authorities?

It may be that the right to private emotion is the next personal freedom. It remains to be seen whether we’ll be asked to surrender it.

(Again. Welcome to this absurd future).
