LO1Demonstrate a critical understanding of current techniques of task analysis, design approaches and user interface implementation within specific human-computer environments.
LO2Critically appraise methods and guidelines for HCI evaluation, and conduct an evaluation using proposed evaluation techniques and evaluative criteria.
LO3Assess the various trends towards more sophisticated interfaces with regard to Web 2.0, online communities, inclusive design, and multimedia.
Begin by providing the following 3 subsections, and base them on good HCI design practice from appropriate HCI literature.
What criteria you are going to evaluate against, and why?
Which TWO evaluation techniques are you going to use, and why?
Provide an outline plan for each of the two techniques.
Critically evaluate the web site pairs using the TWO techniques of your choice with at least 5 participants, using the plans you drew up earlier. You are encouraged to select participants whose computer skills differ from one another, bearing in mind that they must be 18 years old or above. Through this sampling, you can still gain valuable information by selecting participants who, as a group, mirror the larger population. You must obtain ethical consent from your participants to conduct any form of evaluation.
Describe what you have discovered in terms of usability and user experience for both the web sites, based on relevant HCI principles of your choice and justify your solutions. As per the lectures, consider the possible influences of Persuasive Design and Responsive Design as part of your evaluation. Document all your findings clearly in your portfolio.
document the results of the evaluation of both web sites, showing clearly what the participants did. Participants’ names must be anonymised.
You must include in the appendices ALL the documentation and briefing notes you gave to participants. You are encouraged to use charts, diagrams and tables to present the data so that it is clearly legible to the reader.
Take a critical view based on your judgement of the evaluation data you gathered using both methods. Consider and evaluate your findings, linking them to relevant HCI literature. In other words, do your reading and research in a critical manner; do not take everything at face value, and do not always believe everything you read.
Suggest possible solutions to all usability and user experience problems you have described from both the evaluation processes under B) above.
