Stealing From a Cashierless Store (Without You, or the Cameras, Knowing It)

Excerpt from this article:

Standard Market is the latest entry in the emerging fray of retail automation, where companies are throwing cameras, sensors and machine learning into grocery stores to replace the checkout line. In January, Amazon opened its first cashierless Go market in Seattle to the public; it has since opened more of the stores. In China, experiments in cashierless stores abound, using radio frequency identification tags and a self-checkout process that involves scanning a Quick Response code or your face.

Standard Cognition’s approach is different. It relies exclusively on the ceiling cameras and artificial intelligence software to figure out what you are buying. The cameras document shoppers’ movements, speed, stride length and gaze. The store knows when I glance at a poster and for how long. It knows if I slowed down, grabbed a chocolate bar and put it back. It knows if my body is facing the dried mangoes but my face is set on the popcorn.

And it knows (or is trying to know) when I am planning to steal.

This Phone App Knows If You’re Depressed

Many smartphone apps use a device’s sensors to try to measure people’s physical well-being, for example by counting every step they take. A new app developed by researchers at Dartmouth College suggests that a phone’s sensors can also be used to peek inside a person’s mind and gauge mental health.
