Microsoft aims to improve maps with GPS data from 33,000 Beijing cab drivers
Microsoft's already added a Taxi Fare Calculator to Bing Maps to help keep your cabbie in check, and it's now actually enlisted the help of some 33,000 Beijing cab drivers in an effort to further improve driving directions. More specifically, it's relying on GPS data collected from the cab drivers' cars over a period of three months, which has since been funneled into a system called T-Drive created by a team at Microsoft Research Asia. Just how big a difference can a bit of local know-how make? Apparently, about a 16 percent cut in time on average, or roughly a savings of five minutes for every 30 minutes of driving. Of course, it won't do anyone outside of Beijing much good at the moment, but there's plenty more GPS-equipped cabs out there if Microsoft ever decides to expand things.
Microsoft dreams of smart charging pad with information display (update: prototype pics and video)
It's no Courier, but for a charging pad, this is a pretty interesting concept. According to a patent filed by Microsoft's Beijing office, the idea for such a pad is that it can have one side dedicated to inductive charging (maybe for a future Zune or even Microsoft's own phones), while the other side can be used for displaying useful information "such as weather conditions, sports scores, news headlines." It may not sound very practical at first blush, but have a listen at this -- the built-in accelerometer and the charging surface's load detector help determine which side isn't in use, thus switching that side off to reduce power consumption. Voilà! As for why the eggheads suggested adding a light panel for glowing up a glass prism -- it's the new crystal ball. Update: looks like this device has been around since March 2009! A tipster -- who happens to be affiliated with Microsoft Research Asia -- has just hit us with some photos of a prototype device based on this patent. It's called the uPad (please, don't start) and was produced as souvenirs for Microsoft Research Asia's 10th anniversary. As you can see after the break, the uPad wirelessly charges a modified Wireless Laser Mouse 7000. We want one. Update 2: and now we have a video -- narrated in Chinese -- after the break. Thanks, bfishadow!
Microsoft's Photo2Search for cameraphone queries
In one of the most ambitious projects to date for associating real-world objects with digital information about them, a team from Microsoft Research Asia is in the final stages of developing a platform for photo-based searches. Rather straightforwardly called Photo2Search, the technology was developed against the backdrop of a growing cameraphone market, whose widespread adoption is bringing portable computing to the masses but whose limited input options continue to deliver a frustrating search experience. Project leader Xing Xie came up with the idea for a database that could be queried via texted or emailed phone pics in late 2004, but at the time both machine-based photo identification and computer-vision algorithms were too slow and rudimentary to suit their needs. Over a year of work has refined the technology to make it faster, but more importantly, relevant -- unlike older software, Xie's version is now able to discern features that allow it to match specific objects and not just those which share similar characteristics. Unfortunately there are no immediate plans for rolling out this technology to consumers (it's still not quite ready for primetime, apparently), but since most of today's phones produce photos that are little more than a pixelated mess, we're probably not quite ready either.[Via picturephoning and MocoNews]
