Creating User Interfaces

1
Creating User Interfaces

• General remarks on handhelds
• Websites for regular mobile devices
• NewsHandheld functions
• Classwork/Homework Start plans for team
  presentation on hand-held products

2
Hand held devices

• Made possible by improvements in semi-conductors
• Logic and memory
• Batteries
• Electro-mechanical devices
• Keys
• Camera (CCD), other devices

3
Limits

• Human interface?
• Fingers arent getting smaller
• Advantages and disadvantages of very small, but
  costly devices
• ?

4
Synergies

• Handheld device MAY be connected to other things
  (infrastructure)
• Networks
• Websites
• Programs
• and these factors may be as important as the
  instrument itself
• Example Iphone supported only by certain
  network, only available in certain areas.

5
Two distinct but related situations

• Web sites that detect client hardware
• Web sites for downloading to hand heldIncluding
• Coordination of ipod broadcast
• Synchronization of schedules

6
News paper / news readers

• Regular computer
• Hand held

7
Aside

• This is something apart from issue of viability
  of print newspapers, relating to the issue of
• Revenue stream from advertisements, especially
  classified ads
• Generation of news from professional journalists,
  editors versus bloggers, specific audiences

8
Hand held products

• Individual functions plus combinations
• Phone (phone plus carrier)
• Voice
• Text
• Picture video
• Personal Digital Assistant (maintain calendar,
  notes) (PDA plus carrier)
• Email, sharing
• Digital camera
• Still and video
• Audio player
• Hand held GPS (geographical positioning system)
• Book reader
• ?

9
How to analyse / rate

• Should each team take 2-3 products
• Compare across multiple functions
• Compare for one main function
• Phone
• Music
• Camera
• PDA?
• GPS?
• Book reader
• ?

10
Assessment

• Evaluate effectiveness efficiency
  satisfaction
• Do the functions work? Do you use all/many/most
  functions
• E.g., modes for camera groups for phone
• Are they easy to do (without manual or on-line
  help or, for complex ones, with help)
• Cost/benefit do more expensive products in the
  product group provide more functionality?
• ?

11
Assessment, continued

• The team needs to come up with the attributes to
  measure and the metrics (measuring scheme).

12
Task Presentation

• I want
• Research (product reviews) and
• Your own assessment plus (possibly) friends
• Will work best if you own the products within
  your group
• I also want
• Charts with pictures of screens, diagrams,
  results

13
Classwork/Homework

• Decide on teams 4 students each
• Decide overall approach
• Combinations versus base functions?
• Product sets

14
Aside teams

• Most work in industry is team work and
• Most work requires presentations
• So.that is why I assign it!
