A new system relies on short-range Bluetooth signals emitted from people’s smartphones to trace who they've been in contact with. These signals represent random strings of numbers, likened to “chirps” that other nearby smartphones can remember hearing, offering a way to find people who may have been in contact with people who have tested positive for Covid-19.

Bluetooth signals from your smartphone could automate Covid-19 contact tracing while preserving privacy

A system that enables smartphones to transmit “chirps” to nearby devices could notify people if they have been near an infected person.

A simulation system invented at MIT to train driverless cars creates a photorealistic world with infinite steering possibilities, helping the cars learn to navigate a host of worse-case scenarios before cruising down real streets.

System trains driverless cars in simulation before they hit the road

Using a photorealistic simulation engine, vehicles learn to drive in the real world and recover from near-crash scenarios.

“I’ve recently encountered researchers at a loss for how to describe their visualizations in ways that make them more accessible. When visualizations appear in, say, textbooks, scientific publications, or educational materials, they might appear as braille translations of the image, but more often they appear as textual descriptions. But what is the best way to describe a visualization?,” sa...

3Q: Collaborating with users to develop accessible designs

An MIT team discusses the pitfalls of “parachute research” and the importance of “sociotechnical” factors.

Roboticists are developing automated robots that can learn new tasks solely by observing humans. At home, you might someday show a domestic robot how to do routine chores.

Showing robots how to do your chores

By observing humans, robots learn to perform complex tasks, such as setting a table.

MIT cognitive scientists have developed a computer model of face recognition that performs a series of computations that reverse the steps that a computer graphics program would use to generate a 2D representation of a face.

A new model of vision

Computer model of face processing could reveal how the brain produces richly detailed visual representations so quickly.

CurveBoards are 3D breadboards — which are commonly used to prototype circuits — that can be designed by custom software, 3D printed, and directly integrated into the surface of physical objects, such as smart watches, bracelets, helmets, headphones, and even flexible electronics. CurveBoards can give designers an additional prototyping technique to better evaluate how circuits will look and f...

Integrating electronics onto physical prototypes

In place of flat “breadboards,” 3D-printed CurveBoards enable easier testing of circuit design on electronics products.

MIT's new system allows a self-driving car to situate itself in snowy conditions.

To self-drive in the snow, look under the road

Weather’s a problem for autonomous cars. MIT’s new system shows promise by using “ground-penetrating radar” instead of cameras or lasers.

In a new metadata-protecting scheme, users send encrypted messages to multiple chains of servers, with each chain mathematically guaranteed to have at least one hacker-free server. Each server decrypts and shuffles the messages in random order, before shooting them to the next server in line.

Protecting sensitive metadata so it can’t be used for surveillance

System ensures hackers eavesdropping on large networks can’t find out who’s communicating and when they’re doing so.
