2. Nina Reeves, Module Tutor 2 Overview User Centred Design Theory Standards Practical Case study PRiMMA project (Open University and others) Relate to Assignment 2

3. Nina Reeves, Module Tutor 3 User Centred Design overview

4. Nina Reeves, Module Tutor 4 UCD Standards ISO standard ISO 13407:1999 Human Centred Design Processes for Interactive Systems Main principles Understand and specify the Context of use eg: user and task characteristics + environment of use Appropriate allocation of function btw user and system Active involvement of users in design process Iteration of design solutions Co-operative evaluation Multi-disciplinary design teams To do this we need to understand the context

5. Nina Reeves, Module Tutor 5 Co-operative evaluation (Faulkner, 2000) Arose out of criticism of experimental methods OK for aspects which could be closely controlled Mobile phone calculator task Less suited to multimedia interfaces - games Co-op evaluation aims to identify and rectify problems with a prototype Requires little training – cost effective for industry 4 steps Recruit users Prepare tasks Interact with the user and the system records what happens Summarise the observations Caveat Only as good as the task(s) chosen

6. Nina Reeves, Module Tutor 6 How about designing from scratch? Assignment 07/08 Watercooler design and evaluation In a large, multinational organisation, it is often difficult to get to know who has a particular expertise that a current project you are working on requires. One usually relies on looking at the intranet or asking around in the office and hoping that someone knows.   Social networking sites can be handy, but managers often feel that staff waste time on them. Apart from Common Rooms beloved of academics, there is a well-known phenomenon called the “watercooler” effect in the USA where people gather to collect a drink and conversations start and “intelligence” is shared. It is a challenge for organisations to find a way to capture the intelligence which is shared verbally in this way and yet maintain the confidentiality of company business and protect intellectual property. See http://mu220watercoolerproject.pbworks.com/Background+info+page   Your task is to design a system which would work via a touch sensitive whiteboard and webcam situated near the refreshments area of an office. It is a “walk up and use” multimedia system so all interaction should be intuitive and language independent so that it can be used across the globe.

10. Nina Reeves, Module Tutor 10 Scenario-based design What we need is to let our imaginations go… What might users want to do… Used at the start Eg: Storyboard based on what you think someone might want to do Scenario based design Central to most scenario based design is a textual description or narrative of a use episode. This description is called a scenario. The scenario is described from the user point of view and may include social background, resource (e.g. disk space, time) constraints and background information. The scenario may describe a currently occurring use, or a potential use that is being designed and may include text, video, pictures, story boards, etc. http://ldt.stanford.edu/~gimiller/Scenario-Based/scenarioIndex2.htm

11. Nina Reeves, Module Tutor 11 Scenario-based design - overview

12. Nina Reeves, Module Tutor 12 Eg: what did they do? Watercooler design 07/08 Users’ plans Find a person with expertise, who’s working on a particular project Navigation – find a place, office, lab, facility General knowledge about What’s on? Build trust between colleagues thro’ shared interests Users’ situated actions Drink in hand Avoid keyboard use Gesture better – think “Minority report” or “Disclosure” Accessibility – visual/audio/physical impairment Scenarios of use Describe in words how someone might want to use these systems Example follows for practice

13. Eg: RoSPA game design 09/10 Users’ plans Learn about hazards/ways to stay safe Have more fun than just reading a book Users’ situated actions Finding out in advance? Improve hazard perception Practise asking “What if?” Scenarios of use Part of a learning module Fun What kind of a game? Identifying hazards/correcting hazards/collect rewards/compete with others… Nina Reeves, Module Tutor 13

15. Assignment 2 – preparation 4 design Mobile Car Sales training app Who will use this? …Car sales staff What kind of lives do they lead?...busy, social, stressful… What technology are they happy with? What kind of customers do they meet? What are their needs? What assumptions should be made about the company who employs them? What research have you done wrt competitive survey? Write out the scenarios in words Nina Reeves, Module Tutor 15

16. Nina Reeves, Module Tutor 16 What now? Could conduct a Focus group with sales staff Facilitator encourages the group to rank the features elicited and talk about any further scenarios May provide other material eg: magazines, adverts etc concerning image related features of the vehicles List features Subsequent use of questionnaires might collect data ranking features in importance Data analysis would need Rank correlation For Assignment 2… Think about the data (aspects/features of the cars that can be changed) that you want to include Design for a mobile device – think screen size!!
