An Interaction Model and Infrastructure for Localized Activities in Pervasive Computing Environments
International Conference on Pervasive Services
By Helder Pinto, Rui Jose, Jose Creissac Campos
Issue Date:July 2007
This paper presents an interaction model for pervasive computing environments supporting localized activities, i.e., activities strongly associated to a specific physical environment. We are particularly interested in activities performed by occasional vis...
New directions for system support in Pervasive Computing
Pervasive Computing and Communications Workshops, IEEE International Conference on
By Helena Rodrigues,Rui Jose,Arlindo Santos,Bruno Silva
Issue Date:March 2012
In this paper, we discuss alternative paths towards system support for Pervasive Computing that are based on a balanced combination between global services and situated devices that we hypothesise will be the key to widespread deployment of Pervasive Compu...
Open Display Networks: A Communications Medium for the 21st Century
By Nigel Davies,Marc Langheinrich,Rui José,Albrecht Schmidt
Issue Date:May 2012
Open public display networks could emerge as a new communications medium for the 21st century, but this transformation can only occur if the technology moves from its current, closed model to a new, open one.
Place-Aware Content Selection from Dynamic Web Sources for Public Displays
Signal-Image Technologies and Internet-Based System, International IEEE Conference on
By Fernando Reinaldo Ribeiro, Rui José
Issue Date:December 2009
Public digital displays could greatly benefit from the ability to dynamically select from the Internet content items that would be strongly related with the place where each display is installed. Generically, this is similar to the type of problem addresse...
An Open Architecture for Developing Mobile Location-Based Applications over the Internet
Computers and Communications, IEEE Symposium on
By Rui José, Adriano Moreira, Filipe Meneses, Geoff Coulson
Issue Date:July 2001
Abstract: The mobile Internet is enabling a broad range of new applications that dynamically obtain information that is relevant to their current location. This type of application would greatly benefit from generic mechanisms for supporting the associatio...
Instant Places: Using Bluetooth for Situated Interaction in Public Displays
IEEE Pervasive Computing
By Rui José, Nuno Otero, Shahram Izadi, Richard Harper
Issue Date:October 2008
Instant Places is an investigation into the role of Bluetooth presence and naming as techniques for situated interaction around public displays. The authors' utilization of Bluetooth naming extends beyond identity representation, introducing the use of a s...
HAPS Systems Performance Using a Ka-Band Channel Model Based on a Time Series Generator
Electronics, Communications, and Computers, International Conference on
By José Luis Cuevas-Ruis, José A. Delgado-Penin
Issue Date:March 2005
<p>Actually, there are analyzed many applications inside the Ka and upper bands around the world. However, when a link is implemented at frequencies above 10 GHz, the attenuation due to the rain and others weather effects increases considerably. Ther...
Pins and posters: Paradigms for content publication on situated displays
IEEE Computer Graphics and Applications
By Rui Jose,H. Pinto,B. Silva,A. Melro
Issue Date:March 2013
Public-display systems are still far from being a medium for meeting people's diverse communication goals. Moving toward open displays will require publication paradigms that can overcome the challenges of meaningful engagement and enable users to fully un...
