Talk at Ubicomp 2007.
Industrial health and safety is an important yet largely unexplored application area of ubiquitous computing. In this paper we investigate the relationship between technology and organization in the context of a concrete industrial health and safety system. The system is designed to reduce the number of incidents of “vibration white finger” (VWF) at construction sites and uses wireless sensor nodes for monitoring workers’ exposure to vibrations and testing of compliance with legal health and safety regulations. In particular we investigate the impact of this ubiquitous technology on the relationship between management and operatives, the formulation of health and safety rules and the risk perception and risk behavior of operatives. In addition, we contrast sensor- network inspired and smart artifact inspired compliance systems, and make the case that these technology models have a strong influence on the linkage between technology and organization.

17. Invisible Risks
Risk perception is poor
Lesson 1: Shift from H&S compliance to increasing awareness
Gerd Kortuem - Lancaster University - 2007 - kortuem@comp.lancs.ac.uk
18. Self-Image and Social Pressure
Safety equipment often not used
Lesson 2: Personal and social “invisibility” becomes key design goal

19. Past Experiences & Narratives
GPS had been experienced as surveillance technology
Lesson 3: Technology narrative should be part of the design

20. Developers’ Blind-spot
(a) Wider organizational aspects are perceived to be of low importance
(organizational culture, re-distribution of power, organizational disruption,
societal issues, privacy and security concerns)
(b) Even organizational issues that are considered to be of importance
often do not actually influence the design process

26. Points to Take Home
• Industrial workplace is opportunity for ubicomp
• Design process must investigate organizational context
• Architecture is not neutral
