Ashirase aims to develop an in-shoe navigation system to help support the visually impaired with walking and routines. The company hopes to have a viable product to market before the end of March 2023. The device fits around each foot, and includes a motion sensor attached to the outside of the shoe. Pairing with a smart phone app, the device will vibrate based on routes set in the app. The left side of the left foot will vibrate to indicate a left turn (and the opposite for a right turn), while the toes of each foot will vibrate to maintain a forward trajectory.

Animals do not get lost
the more we learn about how animals travel the more we can help them keep doing so. Knowing that salmon follow the scent of their natal stream, scientists added an odor to hatcheries and used it to lure the fish back to the Great Lakes, years after pollution levels there, now ameliorated, caused a local extinction. Knowing that peak songbird migration lasts no more than 6 or 7 days in a given area, ornithologists have led successful efforts to dim lights during the relevant time frame. Knowing that a shorebird migrating 32K km a year uses less than 2.5m2 of land along the way has helped conservationists engage in smaller, more affordable, more effective preservation.
GPS ankle bracelet rioter
Don’t wear a GPS ankle bracelet during cosplay
Betancur delivered that to investigators in a way few others involved in the half-assed insurrection have. Behold this galaxy brain at work. The case relies in part on location data produced by the GPS unit that the man was wearing for a prior offense.
Improving urban GPS
Combine raw GPS measurements with building outlines, plus some linear algebra, to reduce GPS errors in dense urban environments by 75%.
Fused LEO GNSS
continuous assured PNT service over ±60° latitude (covering 99.8% of the world’s population) with positioning performance exceeding traditional GNSS pseudoranging would cost less than 0.8% of downlink capacity for the largest of the new constellations, SpaceX’s Starlink. where previous proposals targeted positioning precision on-par with traditional GNSS pseudoranging (on the order of 3 m), fused LEO GNSS can improve on this by more than an order of magnitude to 20cm
Dead drop drugs
Most Russian drug dealers don’t hand off drugs anymore—they stash them in geotagged hiding spots ready for pickup by online buyers.
Parallel reality
very cool, basic idea: a display can show different pictures to different people at the same time, by taking advantage of the viewing angle (which means you have to know precisely where the viewers are)
Realtime 10 cm Location
Global Differential GPS uses a large ground network of real-time reference receivers, innovative network architecture, and real-time data processing software, the GDGPS System provides sub-10 cm positioning accuracy and sub-nanosecond time transfer accuracy anywhere in the world, on the ground, in the air, and in space, independent of local infrastructure.
AT&T sells your data
The suit seeks an injunction to ensure that AT&T can no longer collect and sell this data. The class action represents several California AT&T users who say they were never informed, nor gave consent, for their location data to be used in this fashion
Restaurant Patterns
what is the taco capital of the US? What is the exact longitude where Chinese food eclipses tacos? What about regional preferences, such as the South‘s affinity for BBQ? We reached out to Google for answers, and they provided an anonymized dataset based on actual restaurant visits
