Revolutionizing Behavioral Measurement with MIT’s Marko System

Good data goes a long way, but sometimes it is hard to collect.  This is especially so in the behavioral sciences.  We have historically relied on self-report, or quantitative observations that require other people to manually tally rates of occurrence.  Using other people inherently introduces reliability and validity issues.  Moreover, some naturalistic settings create distractions or other motivational issues that conflict with data collection.

But those days are soon coming to an end.

New technology out of MIT can automatically track your behavior within a three dimensional vector-based space, and without the need for invasive video or for other people to manually record data.

The device is called Marko, and it works by emitting radio signals across a space and measuring their reflections from moving people…sort of like a radar system for people.  Initially, the device has to “learn” about your unique movements for a bit such that it can identify you and differentiate you from others.  After that, no one needs to wear anything.

Marko has already shown successes in a variety of settings, the details of which will be presented at the 2019 Conference on Human Factors and Computing Systems. In one example provided by BigThink, Marko monitored a patient with dementia in an assisted living facility.  The staff often reported that he would appear agitated but didn’t know why.  They noted that “over a month, they measured the patient’s increased pacing between areas of their unit — a known sign of agitation. By matching increased pacing with the visitor log, they determined the patient was agitated more during the days following family visits. This shows Marko can provide a new, passive way to track functional health profiles of patients at home, the researchers say.”

Thus, Marko potentially allows for meaningful functions of behavior to be reliably identified.  The technology removes all of the common issues involved with data recording done by humans which affect the reliability and validity of the data itself.

  1. Well that was a horrible example of using Marko. The assisted living facility could have ran a separate, probably cheaper program, and would probably figure this stuff out. Plus, at the end of the day, we are still defining behaviors and the rules that follow. Have you ever tried to create a computer program to fix those issues? These are all very expensive ways to get the same data. We are all just scared of human error to figure out the end result that we put our priorities in the hands of robots. Behavior analysis, when at the personal level, should be helped at the personal level (not at a robotic level). There is a great tradition of humanism in BA. We should definitely watch ourselves when it comes to new technologies.
