1.3.2 Human/product interaction The balance of properties needed in a particular product varies enormously, depending on the exact duty that product will perform in service, the environment in which it will operate, and the way it will interact with the user or consumer. The last factor has assumed much greater influence in product design as competition between different manufacturers sharpens the perception of quality in users’ eyes. The study of human-product interactions is variously known as human factors or
Introduction Polymers are materials composed of long molecular chains that are well-accepted for a wide variety of applications. This unit explores these materials in terms of their chemical composition, associated properties and processes of manufacture from petrochemicals. The unit also shows a range of products in which polymers are used and explains why they are chosen in preference to many conventional materials. This unit is from our archive and it is an adapted extract from Design and ma

This unit will introduce you to the modelling process enabling you to recognise that systems models may be used in different ways as part of a process for: improving understanding of a situation; identifying problems or formulating opportunities and supporting decision making.

Like the hard systems approach, soft systems methodology is not seen as a ‘one pass’ procedure, but as a learning process. Iteration is a feature of the methodology's application. Learning is achieved in both approaches by the use of models, although soft systems has subsequently been enhanced to include a specific analysis of the culture and politics of the problem situation, as shown in Author(s): Acknowledgements Prepared for the Course Team by Simon Buckingham Shum Except for third party materials and otherwise stated (see terms and conditions), this content is made available under a Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Licence 4.19 Technologies and explicit knowledge continued The following examples give a taste of what is now making the transition from research laboratories into commercial products. Large hierarchical information structures are extremely common, whether in libraries, organisational charts or websites. Displaying such large structures is a challenge, and since the user soon runs out of screen space, navigating them can be tedious. Screen 7 shows a system that uses animation and carefully designed graphical effects to give the impression of manipula 4.18.2 Information visualisation We read increasingly of the problem of information overload. Earlier, we emphasised the importance of designing appropriate information representations to assist human interpretation in order to create actionable knowledge. Information visualisation is concerned explicitly with designing representations using intuitive visual metaphors and graphics to highlight the most important aspects of information structures and processes. Information visualisation is a rapidly emerg 4.17.1 Software agents A software agent is a program that displays a certain minimum level of autonomy – it acts as a surrogate for a human user. An agent does something for the user automatically, when given instructions. The more sophisticated the agent is, the fewer instructions it needs, and the more capable it is of making decisions on its own – the more ‘agent-like’ it is. An agent can be run on a client (the user's machine) or on a server (for example, a web server). It can also be anchored (sta 4.14.1 Metadata
Metadata is descriptive data about data. This has also come to refer to a way of tagging documents (on the Web or any other repository) with structured, descriptive information. For example, to describe a unit in B823, we would expect to have concepts such as title and author, but perhaps also prerequisite or core concepts. Translated into a metadata scheme, this might appear as follows (typically metadata fields use <angle brackets> to delimit each m
Access to safe, clean and sustainable energy supplies is one of the greatest challenges facing humanity during the twenty-first century. This unit will survey the world’s present energy systems and their sustainability problems, together with some of the possible solutions to those problems and how these might emerge in practice.
