Creating User Interfaces

1
Creating User Interfaces

• Ideas Trends
• Homework Post constructive comments. Work on
  project.

2
Idea way to view progress

• Technology driven
• solution searching for problem
• What is killer ap?
• Problem driven
• problem searching for solution
• Interaction of two
• technology to problem to re-direction of
  technology

3
Trends

• Voice Speech Recognition
• general unrestricted, still coming?
• dictation systems in use
• directed speech (VoiceXML) substantial use
• phone help desks, 800 information, pharmacy
• car directions
• factory
• Case of actual problems re-directing research on
  technology

4
Trends

• Immersion / ubiquity (natural speech recognition
  access to files databases)
• general be anywhere (somewhere), ask question
  and get answer synthesizing information from
  anywhere including own computer files
• search (google competitors)
• keywords only. Access to growing number of files
  (e.g., PowerPoint charts)
• Dark web
• Semantic Web still in development

5
Keywords

• enough in certain cases
• search (google still ahead of others, notably Ask
  Jeeves)
• Ask artist Jacques Lipchitz

6
Natural language or not

• false assumption best interface is people
  talking to computers
• Abdominal study
• Technical questions and technical answers
• PI said please don't make me use English

7
Games

• Puzzles
• new ideas (hexic not quite next tetris)
• Action
• improved plots
• improved integration 3D modeling and video
  requires improved performance
• Peer to peer games
• improved networking
• ideas and marketing
• Trend to large communities playing game
• ??

8
Meta trend

• User-centered design
• consumer rebellion against products
• buggy released too soon?
• overly complex (fat)
• My complaint want the old Paint Shop Pro back
  simple, cheap
• Open Source
• distributed developmentMaybe not diverse enough

9
Meta trend

• Outsourcing / off-shoring
• Technical work done by remote group using fixed
  specifications
• Initial motivation costs, eventually skills
• My theory IT (information technology
  professionals) did a poor job relating to actual
  users rest of the company so that proximity was
  not valued.

10
Meta trend

• Evaluation of technology
• Is it good enough to provide substantial value
  even if not close to perfect / ideal?
• Phone directed speech / speech synthesis
• Language translation
• Google/yahoo/etc. directions/locations

11
Meta trend / issues

• Concerns with
• Viruses
• Spam
• Unwanted cell phone messages audio or text
• Privacy (identity theft, insider crime)
• Problem in search of technology solutions

12
Meta trend

• Globalization issues
• ICANN remain with US Dept. of Commerce?
• Languages
• Localization

13
Web services

• Applications put together using building blocks
• Example google maps API
• Example (maybe) paypal service
• XML frequently used as format for interface
• Other?

14
Capability versus Productivity

• Capability
• can it be done
• Productivity
• do it better, faster, cheaper
• Example XML, etc. can be used to produce
  interfaces for multiple platforms from same
  content in more efficient, less error-prone way.

15
Grab bag

• Technology wireless plus gps (add more
  functionality to cell phone/PDA)
• Technology touch, gesture, eye-movement
• Problem identification
• individual voice, non-invasive DNA, etc.
• in mass image recognition issues of speed and
  accuracy
• Problem understanding of complex data
  visualization techniques for combining data
  sources

16
Homework

• Post constructive comments on other proposals.
• Work on final project
• Remember that you need to test with user(s) and
  report

17
Final presentation

• Repeat purpose, audience, technology
• Describe implementation
• Diagrams as appropriate
• Demonstrate program
• Report on users responses/feedback
• Describe what you would do for a production
  version of application
• Scale up issues
• Performance
• Hard copy to hand in
• Charts (compressed format)
• Other
