Central Question
Most multimedia in hypertext retains the page-based model.
How do the roles of links and the common structures generated change to fit the media?
Outline
• Hyper-Hitchcock Functionality
• Hypervideos
• Feedback on Hyper-Hitchcock
• Roles for Hypervideo Links
• Hypervideo Structures
• Summary
Hypervideos
Nine hypervideos each authored by 1-2 students in a Computers and New Media class
Recorded up to 1 hour using a DV camera then authored hypervideo in HH
Students had about 1 week for authoring activity.
Riding Down University Drive
Most directly maps geographic structure
Links are choices to stop in at sites along road.
Perspectives on Bridges
Shows bridges between College Station and Austin.
Presents different perspectives (roadway, construction, wildlife) in order.
Links are to seeing different perspective.
“In Danger” Buildings
Visits to buildings identified for demolition on TAMU campus.
Links are to seeing interior and details.
International Dance Festival
Shows bits of performances.
Brief “how-to use hypervideo player” at start.
Links are to seeing more and to next performance.
Preparing for the In-Laws
How-to for cleaning and cooking, includes constant audio commentary.
Links are to greater detail.
How To Make a Sandwich
Presents choices in sandwich creation.
Includes video of options.
Links are to select another option.
Evaluation of Hyper-Hitchcock
Easy to use hypervideo player, to work with video clips, to create composites.
Not as easy to manipulate composites and create links.
Spatial parser correctly interpreted composites.
Link labels were valued by many.
Audio energy graph was only valued by a few.
Automatic segmentation of source video into clips and automatic selection of in/out points did not help.
Structuring Problems
Authoring the two separate structures confused some students• Composition of video clips into linear
videos• Links between linear videos
Need for greater explanation of how the two structures interact
Suggested Features
Ability to have more than one link active at a time.
Ability to specify for video to stop playing at decision point.
Separate audio editor
Text overlays and video effects
Roles of Links
Detail Links
Prerequisite Links
Related Information Links
Alternate View Links
Action Choice Links
Hypervideos Mimicking Hypertext
Detail links resulted in sieves.
Some sieves included links from one detailed section to the next (shortcuts).
Related information links also created tangles.
Alternate view links likely to generate mirrorworld or counterpoint structures.
Hypervideo Differences
Split/joins and mirrorworlds used to merge alternate courses of actions or perspectives.
Return behaviors used to cause merging paths, thus the structure looks like a sieve.
