A Case Study in Rapid Prototyping
Since the first quarter of 1988, Pratt & Whitney (P&W), a Division of United Technologies
Corporation (UTC), has been involved in the development for the use of rapid prototyping
technologies that use a "layer-by-Iayer" building approach. Based on over 4 1/2 years
experience with Stereolithography, this paper will address three aspects of our experience
including: Implementation, Current Operations, and Future PlansMechanical Engineerin
Low-fi skin vision: A case study in rapid prototyping a sensory substitution system
We describe the design process we have used to develop a minimal, twenty vibration motor Tactile Vision Sensory Substitution (TVSS) system which enables blind-folded subjects to successfully track and bat a rolling ball and thereby experience 'skin vision'. We have employed a low-fi rapid prototyping approach to build this system and argue that this methodology is particularly effective for building embedded interactive systems. We support this argument in two ways. First, by drawing on theoretical insights from robotics, a discipline that also has to deal with the challenge of building complex embedded systems that interact with their environments; second, by using the development of our TVSS as a case study: describing the series of prototypes that led to our successful design and highlighting what we learnt at each stage
Technology inspired design for pervasive healthcare
Pervasive healthcare technologies are increasingly using novel sensory devices that are able to measure phenomena that could not be measured before. To develop novel healthcare applications that use these largely untested technologies, it is important to have a design process that allows proper exploration of the capabilities of the novel technologies. We focus on the technology-inspired design process that was used in the development of a system to support posture and provide guidance by nudging people, and how this has lead us to explore pervasive healthcare applications
Good vibrations: Guiding body movements with vibrotactile feedback
We describe the ongoing development of a system to support the teaching of good posture and bowing technique to novice violin players. Using an inertial motion capture system we can track in real-time a player’s bowing action and how it deviates from a target trajectory set by their music teacher. The system provides real-time vibrotactile feedback on the correctness of the student’s posture and bowing action. We present the findings of an initial study that shows that vibrotactile feedback can guide arm movements in one and two dimension pointing tasks. The advantages of vibrotactile feedback for teaching basic bowing technique to novice violin players are that it does not place demands on the students’ visual and auditory systems which are already heavily involved in the activity of music making, and is understood with little training

Towards a real-time system for teaching novices good violin bowing technique
We describe the ongoing development of a system to support the teaching of good posture and bowing technique to novice violin players. Using an inertial motion capture system we can track in real-time: i) a player’s bowing action (and measure how it deviates from a target trajectory); ii) whether the player is holding their violin correctly. We detail some initial experiments that show that vibrotactile feedback can guide arm movements in one and two dimensions. We then present some preliminary findings from integrating the motion capture and feedback components into a prototype real-time training system. The advantages of vibrotactile feedback are that: i) it does not use the students’ visual and auditory systems which are already involved in the activity of music making; ii) it is an intuitive way to guide body movements
Back to practice, a decade of research in E-government
E-government is a multidisciplinary field of research based initially on empirical insights from practice. Efforts to theoretically found the field have opened perspectives from multiple research domains. The goal of this chapter is to review evolution of the e-government field from an institutional and an academic point of view. Our position is that e-government is an emergent multidisciplinary field of research in which focus on practice is a prominent characteristic. Each chapter of the book is then briefly presented and is positioned according to a vision of the e-government domain of research.E-government, Case study, E-administration, Public domain

The changing face of human-computer interaction in the age of ubiquitous computing
HCI is reinventing itself. No longer only about being user centered, it has set its sights on pastures new, embracing a much broader and far-reaching set of interests. From emotional, eco-friendly, embodied experiences to context, constructivism and culture, HCI research is changing apace: from what it looks at, the lenses it uses and what it has to offer. Part of this is as a reaction to what is happening in the world; ubiquitous technologies are proliferating and transforming how we live our lives. We are becoming more connected and more dependent on technology. The home, the crèche, outdoors, public places and even the human body are now being experimented with as potential places to embed computational devices, even to the extent of invading previously private and taboo aspects of our lives. In this paper, I examine the diversity of lifestyle and technological transformations in our midst and outline some 'difficult' questions these raise together with alternative directions for HCI research and practice
