    Executive Summary The Equipment Management (EM) trial was one of the practical initiatives conceived and implemented by members of The Application Home Initiative (TAHI) to demonstrate the feasibility of interoperability between white and brown goods, and other domestic equipment. The trial ran from October 2002 to June 2005, over which period it achieved its core objectives through the deployment in early 2005 of an integrated system in trials in 15 occupied homes. Prior to roll out into the field, the work was underpinned by soak testing, validation, laboratory experiments, case studies, user questionnaires, simulations and other research, conducted in a single demonstration home in Loughborough, as well as in Universities in the East Midlands and Scotland. Throughout its life, the trial faced significant membership changes, which had a far greater impact than the technical issues that were tackled. Two blue chip companies withdrew at the point of signing the collaborative agreement; another made a major change in strategic direction half way through and withdrew the major portion of its backing; another corporate left at this point, a second one later; one corporate was a late entrant; the technical leader made a boardroom decision not to do the engineering work that it had promised; one company went into liquidation; another went up for sale whilst others reorganised. The trial was conducted against this backdrop of continual commercial change. Despite this difficult operating environment, the trial met its objectives, although not entirely as envisaged initially – a tribute to the determination of the trial’s membership, the strength of its formal governance and management processes, and especially, the financial support of the dti. The equipment on trial featured a central heating/hot water boiler, washing machine, security system, gas alarm and utility meters, all connected to a home gateway, integrated functionally and presented to the users via a single interface. The trial met its principal objective to show that by connecting appliances to each other and to a support system, benefits in remote condition monitoring, maintenance, appliance & home controls optimisation and convenience to the customer & service supplier could be provided. This is one of two main reports that form the trial output (the other, the Multi Home Trial Report, is available to EM Trial members only as it contains commercially sensitive information). A supporting library of documents is also available and is held in the virtual office hosted by Loughborough University Centre for the Integrated Home Environment

    A comparison of processing techniques for producing prototype injection moulding inserts.

    This project involves the investigation of processing techniques for producing low-cost moulding inserts used in the particulate injection moulding (PIM) process. Prototype moulds were made from both additive and subtractive processes as well as a combination of the two. The general motivation for this was to reduce the entry cost of users when considering PIM. PIM cavity inserts were first made by conventional machining from a polymer block using the pocket NC desktop mill. PIM cavity inserts were also made by fused filament deposition modelling using the Tiertime UP plus 3D printer. The injection moulding trials manifested in surface finish and part removal defects. The feedstock was a titanium metal blend which is brittle in comparison to commodity polymers. That in combination with the mesoscale features, small cross-sections and complex geometries were considered the main problems. For both processing methods, fixes were identified and made to test the theory. These consisted of a blended approach that saw a combination of both the additive and subtractive processes being used. The parts produced from the three processing methods are investigated and their respective merits and issues are discussed

    Reducing risk in pre-production investigations through undergraduate engineering projects.

    This poster is the culmination of final year Bachelor of Engineering Technology (B.Eng.Tech) student projects in 2017 and 2018. The B.Eng.Tech is a level seven qualification that aligns with the Sydney accord for a three-year engineering degree and hence is internationally benchmarked. The enabling mechanism of these projects is the industry connectivity that creates real-world projects and highlights the benefits of the investigation of process at the technologist level. The methodologies we use are basic and transparent, with enough depth of technical knowledge to ensure the industry partners gain from the collaboration process. The process we use minimizes the disconnect between the student and the industry supervisor while maintaining the academic freedom of the student and the commercial sensitivities of the supervisor. The general motivation for this approach is the reduction of the entry cost of the industry to enable consideration of new technologies and thereby reducing risk to core business and shareholder profits. The poster presents several images and interpretive dialogue to explain the positive and negative aspects of the student process

    Tangible user interfaces : past, present and future directions

    In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users' knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive research is required in or- der to fully understand the implications of tangible user interfaces, to develop technologies that further bridge the digital and the physical, and to guide TUI design with empirical knowledge. This paper examines the existing body of work on Tangible User In- terfaces. We start by sketching the history of tangible user interfaces, examining the intellectual origins of this field. We then present TUIs in a broader context, survey application domains, and review frame- works and taxonomies. We also discuss conceptual foundations of TUIs including perspectives from cognitive sciences, phycology, and philoso- phy. Methods and technologies for designing, building, and evaluating TUIs are also addressed. Finally, we discuss the strengths and limita- tions of TUIs and chart directions for future research

    Sketch-based rapid prototyping platform for hardware-software integrated interactive products

    This paper presents a platform in which interaction designers can effectively and rapidly develop tangible interactive prototypes by sketching. The study aims to build a platform that plays the role of sketching in the hardware-software integrated interactive product design process. The platform consists of three components: a sketch based interactive concept exploration software application called STCtools, a set of physical user interface(PUI) widgets with a key converter and a video projection based Augmented Reality desk (ARdesk). For prototyping, a designer creates hardware and software sketches with pen based computers using STCtools. Sketches of hardware and software are drawn in a client device and composed in an electronic whiteboard, which is the server device. PUI widgets can be physically attached on a foam mockup or on a screen of the client device. The hardware-software integrated simulations are conducted on ARdesk. The sketch simulation is captured and projected onto a paper marker created with invisible infra-red ink
