Human Computer Interaction Assignment
Assessment Tasks -
Passenger Transport Victoria are looking to overhaul their existing MYKI system for passenger ticketing and replace it with something radically different. They have requested that your team propose the user interface design modifications.
1. Perform a user analysis. You must have a clear view of the users of this system. Consider that not everyone is comfortable with the technology. For example, you need to deal with user variation such as age or language skills.
2. Perform a task analysis to identify the tasks the potential users will perform, and in what order.
3. Consolidate your findings from your user and task analysis and propose a design and specify system requirements to realise the recommended interface. For example, the number of items to display, the screen size, what colours, how many different screens to display, the devices to you,the physical design.
4. Develop a low-fidelity (paper) prototype (a minimum of 4 screens). Based on the above requirements, develop a preliminary design of the user interface. At this stage, the prototype is basically a medium to support your initial concept and ideas. For example, the prototype should show where the relevant button locations, how much information would be presented on each screen etc. Low- fidelity prototyping is mainly to allow designers to produce alternative designs expediently without having to go into depth or functionality. Think of low-fidelity prototyping as the 5D tool for: design, draft, decide, discard and do-over.
5. Perform an interim evaluation of your design by creating a method of feedback and asking 3-4 potential users (e.g. friends, family members, classmates, etc.) to complete the feedback for your low-fidelity paper prototype. Carry out the evaluation according to prescribed methods found in the textbook (Shneiderman & Plaisant, 2014) or from other scholarly sources. Use appropriate survey techniques. Analyse the data you have collected from the user evaluation and note down any recommendations as to how you could refine and improve on your initial design.
6. Based on the user test feedback and recommendations develop a high-fidelity prototype. The high-fidelity prototype should be an online mock-up of your proposal and should demonstrate some navigation, although it does not need to work as a complete interface. A minimum of 4 screens should be produced in correspondence to your storyboard. The high-fidelity prototype must be computer based and any software is acceptable including PowerPoint, storyboarding, etc.
7. Create an evaluation plan with recommendations on the tools and methods you intend to use to evaluate the usability of your interface.
8. Produce a report to document the tasks and the outcome of your efforts undertaken for the project. Remember, this report is intended for your employers and as such be professionally formatted and presented. Your report will support the viability of your interface and as such needs to convince your employer that your interface design is satisfactory and that it meets user acceptance test.
Recommended Structure
For the purpose of this project you are assumed to be a professional. As such, you should attempt at your best to reflect this quality in the preparation of the report. As a minimum, the report should contain the following:
- Introduction - State the purpose and objectives of the report.
- Main Body - including a description of each of the tasks listed in the criteria.
- Conclusion - This is basically a summation, consolidating the main points of the report.
- A list of references
- Appendix - includes the low fidelity prototype, high fidelity prototype, and questionnaires and user responses collected in Task D.
