Expanding the horizons of location-aware computing

R. Want, B. Schilit
2001 Computer  
However, we found that the system could differentiate between a button press and the normal operation of the badge, which meant the test button could also be used to send commands to the system.  ...  In the case of Active Badge, you carried an electronic badge-rather than a computer-that informed the computer infrastructure where you were.  ...  While at Olivetti Research (1988-91), he developed the Active Badge, a system for automatically locating people in a building.  ...

Dynamic Privacy Management in Pervasive Sensor Networks [chapter]

Nan-Wei Gong, Mathew Laibowitz, Joseph A. Paradiso
2010 Lecture Notes in Computer Science  
A user study was then conducted to evaluate several privacy management approaches -an active badge system for both online and on-site control, on/off power switches for physically disabling the hardware  ...  Results from a user study indicated that an active badge for on-site privacy control is the most preferable method among all provided options.  ...  Acknowledgments We thank our colleagues at the Media Laboratory who participated in the user study and the deployment of this system, especially Bo Morgan for developing the SPINNERD server.  ...

Providing location information in a ubiquitous computing environment (panel session)

Mike Spreitzer, Marvin Theimer
1993 Proceedings of the fourteenth ACM symposium on Operating systems principles - SOSP '93  
Finally, we report some measurements of the unextended system in operation, focusing on how well the system is actually able to track people.  ...  Our system uses two kinds of location information, which turn out to provide partial and complementary coverage.  ...  Users can hide from our active badge system by simply taking off their badge.  ...

Context-Aware Computing Applications

B. Schilit, N. Adams, R. Want
1994 1994 First Workshop on Mobile Computing Systems and Applications  
We believe that a limited amount of information covering a person's proximate environment is most important for this form of computing since the interesting part of the world around us is what we can see  ...  Instances of these application types have been prototyped on the PARCTAB, a wireless, palm-sized computer.  ...  Acknowledgments A number of people worked on the location systems in our lab, including Marvin Theimer, Mike Spreitzer, Karin Petersen, David Nichols and Phil James.  ...

Evaluating and improving the automatic analysis of implicit invocation systems

Jeremy S. Bradbury, Juergen Dingel
2003 Software engineering notes  
It is especially difficult to analyze software systems developed with the implicit invocation architectural style because the loose coupling of their components increases the size of the finite state model  ...  In one of our examples, we will show how with iterative analysis a system parameter can be chosen to meet the appropriate system requirements.  ...  ACKNOWLEDGEMENTS We would like to thank David Garlan, Serge Khersonsky and Jung Soo Kim for providing us with information and software that served as the basis for our research.  ...

Jumping for Fun? Negotiating Mobility and the Geopolitics of Foursquare

Germaine R. Halegoua, Alex Leavitt, Mary L. Gray
2016 Social Media + Society  
Rather than assume that there is some universal "right way" to engage social media platforms, we interrogate how the location-based social media practice known as "jumping" played out on the popular service  ...  The case study examined in this article highlights the practices of participants who attempt to integrate themselves into the design of a social media system and the "workarounds," tensions, negotiations  ...  Where the main purpose or goal of this community is sharing how to unlock badges foursquare, but now the purpose of it is not there . . .  ...
