Accuracy Charaterization for Metropolitan-scale Wi-Fi Localization
Posted: February 20th, 2005 | No Comments »Yet another excellent Place Lab publication. Accuracy Charaterization for Metropolitan-scale Wi-Fi Localization talks about the feasibility of building and the accuracy of a wede-area 802.11 Wi-Fi-based positioning system with very little calibration overhead. Their experiment show that the can estimate a user’s position with a median positioning error of 13-40 meters (depending upon the characteristics of the environment). They point out that building and deploying location-aware application that are usable by a wide variety of people in everyday situations is arguably no easier now than it was ten year ago. Moreover, most current location systems do not work where people spend much of their time. GPS does not work indoors and works poorly in many cities where the so called “urban canyons” form by building prevent GPS units from seeing enough satellites to get a position lock. They prone a mix approach to positioning to reach ubiquitous availability of location information.

ETH Meeting on Locative and Pervasive Gaming
Posted: February 10th, 2005 | 1 Comment »I lead an interesting meeting with Steffen P Walz, Mathias Ochsendorf from the ETHZ, and Nicolas Nova, Mauro Cherubini from CRAFT. We shared experiences, thoughts and ideas on locative and pervasives games as well as on spatial annotation. Nicolas bloged his notes taken during the meeting. (God brings you here Nicolas!).

Spatial Annotation Getting Mainstream in Two Years?
Posted: February 9th, 2005 | No Comments »Spatial annotation is getting more and more light it seems. The mainstream PCWorld mentionned Siemens Digital Graffiti project in Post-It Notes Go Mobile. According to Siemens, there are about two years from commercial roll-out. It is unclear on how the handle the message positioning (with simple cell IDs?) and how (un)accurate it is. They do not talk about any specific scenario either. I guess that is why there are not rushing it out of their lab.
