Participatory design of sensing networks: strengths and challenges.
ABSTRACT Participatory design (PD) involves users in all phases of design to build systems that fit user needs while simultaneously helping users understand complex systems. We argue that traditional PD techniques can benefit participatory sensing: community-based participatory research (CBPR) projects in which complex technologies, such as sensing networks using mobile phones, are the research instruments. Based on our pilot work on CycleSense, a community-based data gathering system for bicycle commuters, we discuss the benefits and challenges of PD in participatory sensing settings, and outline a method to integrate PD into the research process.

ABSTRACT: Current building management systems (BMS) operate based on conservatively defined operational hours, maximum occupancy rates, and standardized occupant comfort set points. Despite the increasing building energy consumption rates, occupants are not usually satisfied with the indoor conditions in commercial buildings. This study proposes an intermediary communication platform, which enables occupants to communicate their preferences to the BMS. The objective is to facilitate the communication between humans and buildings toward adaptive end user comfort management and to compensate for high rate of discomfort in office buildings. The design process of the intermediary, as well as the participatory sensing approach for deploying it in a test bed is presented. The key element is the interpretation of occupants' preferences in the form of change in the HVAC system operations. The results are presented to investigate the correlation between sensed ambient conditions and the user preferences. The results show that although there is a weak to moderate correlation between ambient temperature, humidity, and occupants' preferences, the variation of correlation for different occupants is relatively high.Proceedings of the Fourth ACM Workshop on Embedded Sensing Systems for Energy-Efficiency in Buildings; 11/2012

ABSTRACT: A new generation of 'behaviour-aware' services are emerging, defining the future mobile social networks. It is important for current mobility models to capture mobile users' behavioural characteristics and also reproduce their effects on the performance of networking protocols. Recent work in mobility modelling focused on replicating metrics of encounter statistics and spatio-temporal preferences. In this study, we attempt to show the sufficiency (or inadequacy) of these mobility metrics in reproducing realistic performance of networking protocols. We provide three main findings: (a) careful parameterisation of the models can replicate mobility metrics; (b) a rich set of communities in real mobile societies exist with distinct behavioural clusters of users; (c) even carefully crafted models surprisingly result in structural dynamics and protocol performance that is dramatically different from the trace-driven performance. These findings strongly suggest a need to re-visit mobility modelling to incorporate accurate behavioural characteristics.International Journal of Sensor Networks 04/2012; 11(3):179-191.

Conference Paper: A low-tech sensing system for particulate pollution[Show abstract] [Hide abstract]
ABSTRACT: We present an ultra low-cost sensing system, which enables participants to see and reflect on the particulates in their air. Drawing on prior work in paper computing, we introduce small sensors for particulate pollution that can be easily assembled from common paper materials for less than $1 USD, and mailed by regular postal service to residents of entire neighborhoods, cities, or geographic regions. Recipients collect particulate samples using these sensors and mail them back to a central location, where the particles are viewed and analyzed via a microscope. The data, which includes rich images of actual air pollution particles, can then be broadcast to larger audiences. This paper details the design of our system and its deployment with a local air quality activist community. We conclude by highlighting the tradeoffs between high-tech and low-tech sensing, and suggest opportunities for tangible interaction to support rich, new ways of seeing our environment.Proceedings of the 8th International Conference on Tangible, Embedded and Embodied Interaction; 02/2014
