CO32004 MDM Unit 2 Component Parts
Overview • At the end of this unit, you will be able to • Use a principled approach to media selection and presentation • Select appropriate navigation strategies for the degree and nature of user control • Differentiate between interacting with the interface and with content • Consider the above principles in creating documentation for customers and to control projects Unit 2 slide 2 of 24
Relation to Module Outcomes • (1) Identify appropriate media elements for multimedia interfaces • Principled approach • Controlling the project • (2) Evaluate architectures for multimedia applications • Navigation and nature of interaction Unit 2 slide 3 of 24
Multimedia Awareness: • Multimedia allows us to use multiple media elements to represent a given piece of information. • In groups, discuss whether this brings benefits. For example, you might consider: • Coping with different interaction preferences • Coping with different physical capabilities • Reinforcement – eg TV sound effects • Brand association (Halo effect) • Overload Unit 2 slide 4 of 24
Media Presentation and Selection • Issues include: • How much information to display ? • How it should be presented ? • Which media formats to use • Individual preferences • Guidelines available Unit 2 slide 5 of 24
Text and Graphics Unit 2 slide 6 of 24
Functionality but no Form? Unit 2 slide 7 of 24
Form and Function ? Unit 2 slide 8 of 24
Golden Rectangles - 0.618:1 Unit 2 slide 9 of 24
Mondrian Unit 2 slide 10 of 24
Clip Art: Uses and Abuses ? probably best to avoid! Unit 2 slide 11 of 24
Follow-up Exercise • Examine a range of multimedia applications. • Consider the selection of different media elements and how they are combined. • How effectively has each component been used? • Could it be done more effectively ? • Now consider, how much of what you conclude • Is your opinion, • Is fashion, • Is based upon agreed standards?

Navigation Strategies Linear Hierarchical Composite Hypermedia Based on Tay Vaughan (1993) Multimedia Making it Work 1st edn p. 108 Unit 2 slide 13 of 24
Lost in Hyperspace ? • Where am I? • How did I get here? • What can I do here? • Where can I get to? • How do I go there? • What have I seen so far? • Where else is there for me to see? Unit 2 slide 14 of 24
Multimedia Awareness: • Working in groups • Identify application areas which lend themselves to the architectures discussed above (linear, hierarchical, hypermedia, composite) • Identify design strategies to help prevent the user being “lost in hyperspace” Unit 2 slide 15 of 24
Frame based menus Unit 2 slide 16 of 24
Alternative Menus Unit 2 slide 17 of 24
Design Strategies for User Control • Guides, maps, overviews • Progress indicators • Signposting (e.g. menus, “see also”) • Backtrack facilities, breadcrumbs • Controls for dynamic media Unit 2 slide 18 of 24
Interactivity and Multimedia • User engagement in activity • Interacting with content to achieve goals • Real (theatrical) interactivity rather than “point and click” • Users are engaged in wider “activities” • Prof Wendy Hall (Southampton Univ.) • “The interface is a barrier and it’s our job to make it as thin as possible!” (Dec 1993 BCS Multimedia Systems & Applications Conference, Leeds) • Hiroshi Ishii (MIT) – Tangible User Interfaces (HCI2003) Unit 2 slide 19 of 24
Virtual Experiments Unit 2 slide 20 of 24
Encouraging Reflection Unit 2 slide 21 of 24
Multimedia Awareness • In groups discuss • What is meant by interactivity in the context of multimedia? How it can be realised? • Think of some multimedia applications you are familiar with. How interactive were they ? What could be done to make them more interactive ? • In your opinion, what limits the scope of interactivity in multimedia applications ? • Are buttons (or links) prescriptive? Is it a bad thing if they are? Unit 2 slide 22 of 24
Exploring Interactivity • Visit the following web-sites • http://www.usabilitynews.com/ • http://www.bcs-hci.org.uk/ • http://www.hcibook.com/ • http://www.id-book.com/ • http://www.cogs.susx.ac.uk/ECOi/ • to find out more about interactivity Unit 2 slide 23 of 24
Questions to ask yourself • What principles do I follow • In selecting content • In selecting interaction modes • How much control does the customer want the user to have? • In making an aspect of the interface attractive/pretty • Am I neglecting the actual activities of the user • Next Week’s Lecture • Development Lifecycles and Iterative Design Techniques Unit 2 slide 24 of 24
