About This Document

This piece of coursework assesses the learning outcomes of researching user needs and the implications of technology for work practice, analyzing users and their activities, designing input modalities, output media and interactive content to appeal to an audience, and reflecting upon design practice. The coursework has two halves - the Design Rationale and the Models. The Design Rationale emphasizes the choice of solution and supports design decisions with references to specific design guidelines and findings. The Models reflect what you have learned about your users, their tasks, the objects they work with, and the context of use. These models should be useful summaries that support future work and reveal new information and learnings about the design concerns.

2017-2018Submission details: see Hand-in of Reports (p1)Module Learning Outcomes assessed in this piece of courseworkThe learning outcomes for this piece of coursework are:Research user needs and the implications of technology for work practice Analyse users and their activities, and carry forward lessons learned Design input modalities, output media and interactive content to appeal to an audience Reflect upon design practice and discuss the strengths and weaknesses of alternative techniquesAssignment Brief and assessment criteria (these will be discussed within a formally timetabled class)This piece of coursework has two halves – the Design Rationale convinces the reader than the prototype ought to achieve a great user experience. The second half documents what you have learned about the users, tasks and contexts of use at hand, and represents these learnings as a number of models. These models will support continued, iterative design of the interaction.Design RationaleThe design rationale should emphasise your choice of solution (with reference to the evident user need). The motivation for the redesign, and the desired qualities of experience that are sought (ease of use, engagement etc.) were established in the usability test and problem definition, so there is no need to repeat that again. The new information is the choice of solution – a Tree component rather than a menu structure, a link rather than a button. Also, try to support your design decisions with references to specific design guidelines, and findings. Everyone has an opinion about UI design, and everyone believes their opinion is right – to win the argument you need to quote authoritative sources that persuade others that your decision is the correct one .e.g styleguides, textbooks, practitioner websites.You will also need to select the most important issues to explain and emphasise. Like writing a summary, Models

2017-2018See the relevant slides on Analysis. These models should be useful summaries that support future work, and that reveal new information and learnings about the design concerns.For the task and object models I would suggest a relatively high level of analysis state the intended outcomes, and attributes, but omit system specific details, such as particular modes of data entry, or individual user actions – see slides.Example Structure Models Target Max Word Length 1,000words1.

Notes alongside diagrams, and a brief introduction as to how the diagram was produced, is sufficient for 1.1-1.4.Example Structure Design Report Target Max Word Length 2,500words1.
