Disney Research develops capacitive touch that detects multiple users through their fingertips (video)
Creating a truly multi-user, multi-touch display is a tricky prospect. How do you know who's who short of turning the screen into one giant fingerprint reader? Chris Harrison, Ivan Poupyrev and Munehiko Sato at Disney Research have suggested in a paper that fingerprinting on a capacitive touchscreen isn't far off -- it's just what we need to fingerprint that matters. Rather than look for physical ridges, the scientists' method sweeps through AC frequencies to find the exact electrical impedances of fingertips in contact with the screen. Different bodies, different clothes and even different shoes give everyone a unique signature that lets the screen identify specific people, even when they each have multiple fingers in play. The researchers propose that the technique would work well in collaborative workspaces, personalized devices and security, but let's not forget that this is Disney we're talking about: it's placing a strong emphasis on the prospects for shared screen gaming without the limitations we know today. While any practical use is still some distance away, it's easy to see future tablets and tables that are designed from the start to encourage a little socializing.
Modular robots join forces to search and rescue
These collaborative robots remind us a lot of NASA's SuperBot, only with a clear mission to search and rescue (and minus the crazy acrobatics). These modular bots, currently being developed in Germany, work both independently and as a group and are designed for use in applications such as military reconnaissance, surveillance, and even space exploration. When detached the individual bots can work separately to cover large areas over a shorter period of time. The units come together and join by way of a novel conical docking mechanism, allowing them to form a single, more complex robot. Each module is outfitted with a pair of rugged treads, various onboard sensors, a touch sensor, GPS module, and gyroscope to help then navigate and identify their surroundings. At this stage, the robots are pre-programmed, but a future goal is to make them autonomous and to increase the number of collaborative units working as one. The bots have yet to be used in real-world scenarios, however we'd hope that if one fell into a crevice, another one would come to its rescue. Or whatever.
Writely - The (free) Web Word Processor
C.K. told me about Writely a while back, and even when DownloadSquad blogged it in September it was available as an invite-only beta. Worse yet, it didn't (and still doesn't) like Safari. None of that matters now, however, as I just noticed that Writely seems to have opened its doors for all to come and play with a public beta. With how surprisingly cool this service is, I'll overlook the Safari incompatibility for now.What is this "Writely," you ask? Well, at face value it is an online, collaborative word processor with a wealth of extra bonus features such as full formatting support, blog publishing, tagging, multiple format exporting and revision checking. I am seriously impressed with all the features that are available and have already bookmarked it for my paper-writing ventures in Spring. Too bad 37signals' Writeboard doesn't have any of these fantastic features (hint hint guys), otherwise I'd be able to keep everything under one Backpack roof.One funny quirk about Writely: they're very open about how beta their service really is; once you sign in, a "Beta Meter" badge is placed on the right side of the toolbar. Nice.
