Story-Boarding and Interactive Techniques

Department of Information Systems



Learning Objectives

Understand issues in requirements analysis for interactive software

Understand role of prototyping Understand role and characteristics

of story boards as a form of prototype

Appreciate process of storyboarding



Multimedia and Interactive Systems

Interactive / multimedia software focuses heavily on user interaction with the system

E.g. consider a 3D games application– Significant processing may occur, hidden

from users– But for such a system, quality of user

experience is a major part of requirements



Multimedia and Interactive Systems

Besides games, for what other types of application does this hold true?



Role of Prototypes

Critically important to carry out some kind of prototyping

Extent of prototyping depends on:

Prototypes fulfil all the familiar needs…



Role of Prototypes

Appropriate use of prototypes can... …Help to elicit subtle requirements:

…Increase understanding of known requirements (all the above and more)



Role of Prototypes

Appropriate use of prototypes can also...

…Help check …Help with …Save



Kinds of Prototype

Prototypes differ from formal models in that they look like the intended software

Wide range of possible technologies

At one extreme: ‘Paper CASE’



Story Boards

Originally adapted from film, television and cartoon industry, story boards are a form of prototype

“a cartoon strip or series of thumbnail sketches representing successive screen contents and output media, section divisions and relationships and navigation links”



Why Storyboard in Sys. Development?

Much like film, video or cartoon, depends on nature and scale of project

For simple software with short development time, story board is just a rough design aid

For complex projects with multidisciplinary team, story boards may be explicit part of requirements elicitation and documentation



Skills for Effective Storyboarding

Consider an interactive instruction package

Creating a storyboard requires:– subject domain expertise– knowledge of instructional techniques– graphic design skills– understanding of human-computer

interaction– program design and implementation skills– project management skills



Development of a Story Board The next three slides show stages

in the development of a story board for an instruction package

From first rough draft to final software

Don’t try to read them - the resolution is way too poor for this!



First Draft:



Developed Storyboard



Implemented Software



All three preceding examples are from Sarah Price, 1999 “The Art of Storyboarding” at:

www.icbl.hw.ac.uk/~sprice/ctl/index.html#storyboard

(Learning Technology Centre, Heriot-Watt University)



What a Storyboard Includes Can express everything that can

be seen, heard or experienced by the user of a multimedia program





…And the next slide shows a fragment of a navigation storyboard...





Both preceding examples are from Adrian Mallon, 1995 “Storyboarding Multimedia” at:

Interactive Storyboarding

Traditionally story boards were paper-based

A number of software packages support interactive storyboarding

E.g. multimedia authoring tools:




Several purpose-built packages also exist:

See for example:– www.boardmastersoftware.com– www.powerproduction.com– www.filmmakerstore.com

(Most still intended for the film industry)




Interactive (software) storyboarding can give further productivity gains

Software can also help document the software development process
