Researchers developed a sensing system to constantly track the performance of workers – TechCrunch

Published

on

Researchers have come up with a mobile-sensing system that can track and rate the performance of workers by combining a smartphone, fitness bracelets and a custom app.

The mobile-sensing system, as the researchers call it, is able to classify high and low performers. The team used the system to track 750 U.S. workers for one year. The system was able to tell the difference between high performers and low performers with 80% accuracy.

The aim, the researchers say, is to give employees insight into physical, emotional and behavioral well-being. But that constant flow of data also has a downside, and if abused, can put employees under constant surveillance by the companies they work for.

The researchers, including Dartmouth University computer science professor Andrew Campbell, whose earlier work on a student monitoring app provided the underlying technology for this system, see this as a positive gateway to improving worker productivity.

“This is a radically new approach to evaluating workplace performance using passive sensing data from phones and wearables,” said Campbell. “Mobile sensing and machine learning might be the key to unlocking the best from every employee.”

The researchers argue that the technology can provide a more objective measure of performance than self-evaluations and interviews, which they say can be unreliable.

The mobile-sensing system developed by the researchers has three distinct pieces. A smartphone tracks physical activity, location, phone use and ambient light. The fitness tracker monitors heart functions, sleep, stress and body measurements like weight and calorie consumption. Meanwhile, location beacons placed in the home and office provide information on time at work and breaks from the desk.

From here, cloud-based machine learning algorithms are used to classify workers by performance level.

The study found that higher performers typically had lower rates of phone usage, had longer periods of deep sleep and were more physically active.

Privacy experts and labor advocates have long raised concerns about the practice of tracking employees. That hasn’t stopped companies from incentivizing employees to wear fitness tracks in exchange for savings on insurance or other benefits. Startups have popped up to offer even more ways to track employees.

For instance, WeWork acquired in February Euclid, a data platform that tracks the identity and behavior of people in the physical world. Shiva Rajaraman, WeWork’s chief product officer, told TechCrunch at the time that the Euclid platform and its team will become integrated into a software analytics package that WeWork plans to sell to companies that aren’t renting WeWork space but want to WeWork-ify their own offices.

Meanwhile, the team of researchers suggests that while its system of continuous monitoring via wearables and other devices is not yet available, it could be coming in the next few years. It’s unclear if the team is making a calculated guess or if there are designs to try and launch this system as a product.

The team, led by Dartmouth University, included researchers from University of Notre Dame, Georgia Institute of Technology, University of Washington, University of Colorado Boulder, University of California, Irvine, Ohio State University, University of Texas at Austin and Carnegie Mellon University .

A paper describing the study will be published in the Proceedings of the ACM on Interactive, Mobile Wearable and Ubiquitous Technology.

Today’s Wordle Answer #594 – February 3, 2023 Solution And Hints

Published

on

If the answer is still a mystery, the word is “tasty.” Apart from describing food as having agreeable flavor, you could say something or someone is tasty if they’re elegant or tasteful. The word is a diminutive of the root noun “taste,” which is from Old French “tast,” which is the term for the sense of touch (now Modern French tât).

In the original context of its usage around the 1400s, “taste” meant a share or a small portion; or the sense by which the flavor of a thing is discerned; and savor or flavor. But by the late 1600s, it had also taken on the sense of “aesthetic judgment,” or “the ability to recognize and appreciate excellence” (via Etymonline). There are more variations of its usage, however, especially in idioms. For example, if you have a taste for something, it means you have a strong preference or desire for it, and if something’s so bad you can taste it, it means that thing is extremely unpleasant (via The Free Dictionary).

This is all based on the fact that the sense of taste is quite adept at perception and discrimination of refinement or finesse. This is the sense on which phrases like “have a good eye/nose” are also based. On average, the human tongue has 2,000–8,000 taste buds, with hundreds of thousands of receptor cells. To keep the sense of taste as keen as possible, each taste bud gets replaced about every two weeks (via Britannica).

We hope you finish your puzzle before you run out of guesses, and if you have a taste for puzzles, here are more like Wordle to keep you busy.

A New Cybertruck Spotting Just Revealed Two Big Design Changes

Published

on

The first clear change to the Cybertruck has to do with the rearview mirrors. As Electrek correctly notes, the Cybertruck was originally meant to lack side mirrors, favoring the more futuristic solution of body-mounted cameras. Assuming the particular prototype that was spotted on the road in Palo Alto represents recent changes, that’s at least one concession to reality from the aggressively conceptual Tesla truck.

The second, arguably more significant change is to the truck bed. Prior to this sighting, the Cybertruck had yet to be shown with a working, retractable tonneau cover. User Flavio Tronz on Instagram seems to have caught the Cybertruck with the cover half-retracted, suggesting that particular challenge has also been conquered.

In short, the Cybertruck seems to be getting the tweaks and flourishes to be expected for a car that is expected to enter full-scale production soon. The implementation of simple, proven solutions, like side mirrors, suggests that Tesla is getting real about putting their vision of the future on actual roads.

Is It Safe To Charge Your iPhone With Macbook Charger?

Published

on

According to Apple, if you own a Mac laptop or an iPad and have immediate access to the USB power adapter that came with it, you can certainly use it to charge your iPhone without the worry of potentially damaging your mobile device’s battery. It can also be used to charge other Apple products like a pair of AirPods or the Apple Watch. The following Apple USB power adapters are some of the options that can be used to charge your iPhone, provided that you have a USB-to-lightning cable:

  • 5W USB power adapter that came with iPhones that preceded the iPhone 11
  • 10W US power adapter that was included with every iPad Air and iPad Air 2, iPad 2, and iPad mini 2,3, and 4
  • 12W USB power adapter that was packaged with several versions of the iPad Pro

If you have a Mac USB-C power adapter or other third-party adapters that fulfill Apple’s safety standards, they can be used to charge your iPhone as well. Certain USB-C power adapters, when used in tandem with Apple’s USB-to-lightning cable, have the ability to fast-charge an iPhone 8 and later iterations up to 50% battery in about half an hour (via Apple). This includes the 29W USB-C power adapter that accompanied older MacBook models that were released in 2015 onwards as well as the 30W, 35W, 61W, 67W, 87W, 96W, and 140W USB-C power adapters that came with certain versions of the MacBook Air and MacBook Pro. If you own a MacBook laptop and have its Apple-brand power adapter, you should be able to see its wattage printed right on the device itself and determine if it can be used to charge your iPhone.
