Handhelds for Information Retrieval (3)Handhelds for Information Retrieval (3)
• Existing Guidelines for Design- Human Short Term Memory 7+/-2
• Unfamiliar Tasks• Cognitive Overload
- Scrolling and “Clicking” Interfere• Will Not• Can Not• See (?) Not
- Minimal Graphics (Resolution) Affects Landmark Use
- More Skimming, Information Lost- Task Focus Equalized Among Tasks- Leverage Existing Mental Models
• Hierarchical Models• The Right Schema (Appearance)

Web Design IssuesWeb Design Issues
• When Searching for Information in a Small Screen Display
• 28 User Experiment• “Strategic Information Searches”• Desktop PC vs. Palm (IIIc)• More Time on Handheld (Varied)• Information Location Breakdowns at 225 & 350
Words (5 Test Pages)• Accuracy Similar Among Systems

Web Design Issues (2)Web Design Issues (2)• Re-Think Web Design Ideas and Guidelines• “Web Browsing vs. Strategic Information Seeking”• Task-Specific
- Look-Ups (Reminding and Refreshing)- Not Exhaustive Searches (Learning)- “Answer Clearly Articulated Questions”
• Most Guidelines are for Interfaces, Not Information (Architecture)- Not Just Less Information- Not Only Lists, but Structures- IA May Help More Than UI
• On-Line Comprehension- Even Less on Handhelds (Note Cards?)- Context & Concise Information
• Order of Problems & Tasks• Relative Semantic Representations of Information• Timely

Interaction Save Display Space• Design Inspirations- Magic Lens
• Filtering to Modify Presentation• Weather – Traffic – Population Map(s)
- Pad++• Zooming• Panning
- Gestures• Graffiti

Using Small Screen Space Results (4)Using Small Screen Space Results (4)
• Familiarity Improves Interaction• Users Wanted to “Break the UI” - If No
Overlap, No Delay for Interaction• Shorter Delay Time (1/5 second)• Icons First vs. Text First Interaction
• How Would Information Complexity Change this Design?
• Additional Feedback with Audio?

Improving Mobile Internet UsabilityImproving Mobile Internet Usability
• WAP Issues• How Does the Protocol Affect IA?• Put “web-like material on current and future
phone networks” p 673
• Using “ellipsis” to diplay important information elements
• Phones (Still) Currently (Primarily) Support Hierarchical Menus- Orange - LOTS of key presses
• Perfect avg = 8.2• Test avg = 16.5

• Best Match• Possible Match• Function Synonyms (Labels)
- Not Frequently-Used Functions• Dynamic Interfaces (Can) Cause Confusion• Conflicts with Habit• Less Optimal, But Predictable
- WebTwig Dynamic Outline Works- Cursor Keys Need to Be Improved- Avoid Scrolling- Use Action Text
