Recipe for an Usable System! Recipe for an Usable System! Presentation Transcript

  • Recipe for an Usable System ! - September 5 th , 2003
  • Usability
    • It is very common ‘term’ in software but is relevant to any product.
  • Why is it Important ?
    • For an User: it can make the difference between performing a task accurately and completely or not, and enjoying the process or being frustrated.
    • For the developer: usability is important because it can mean the difference between the success or failure of a system.
    • For Management: software with poor usability can reduce the productivity of the workforce
    • ” In all cases, lack of usability can cost time and effort, and can greatly determine the success or failure of a system”
    Contd…
  • Why is it Important ?
    • Given a choice, people will tend to buy systems that are more user-friendly.
  • Some ways to improve usability
    • shortening the time to accomplish tasks
    • reducing the number of mistakes made
    • reducing learning time
    • improving people's satisfaction with a system
  • Ingredients of Usability!
    • Information Design
    • Interaction Design
    • Sensorial Design
  • Sensorial Design
    • Tactile Senses
    • Visual Senses
    • Olfactory Senses
    • Auditory Senses
    Touch, Kinesthetic, Sense of Direction… Smells, Tastes Voice, Music, Sounds Writing, Photography, Typography, Graphic Design, Iconography, Animation, Illustration & so on.
  • Interaction Design
    • Synonym for Experience | vital factor to determine one
    • Have we come across Interaction Design in our daily routine
      • Conversations
      • Most Storytelling
      • Applications
      • Building and Decorating a House
      • Games (of all kinds)
    • It’s the smooth interaction makes a good experience
    • Interactivity is all around us and a deep part of our lives. It has been around for hundred of thousands of years. It is merely new to electronic media.
    Contd…
  • Interaction Design
    • Components of Interactivity
      • Feedback (Responsiveness)
      • Control (Navigation, Accessibility etc.)
      • Productivity (Creation Tools)
      • Communications (Discussion Forums, Chat, Storytelling Engines etc)
      • Adaptivity (Customization, Personalization, Psuedo-Intelligence, etc.)
  • Information Design
    • What is Data?
      • Data is the product of discovery, research, gathering, and creation.
      • It is the raw material we find or create that we use to build our communications
    • To have informational value, it must be organized, transformed, and presented in a way that gives it meaning.
    • So, Information Design is all about Organizing & Presenting the data into a valuable & Meaningful information
    Contd…
  • Information Design
    • The trend is transiting from Age of Data to Age of Information
    • It is imperative to know which media work well for what kinds of messages:
      • text, sound, voice and music, animation, video, illustrations, photographs, and diagrams, video, and other forms
    Contd…
  • Information Design
  • Knowledge & Wisdom
    • A bit on Knowledge:
      • The information when experienced provides Knowledge.
      • The knowledge is communicated through compelling interactions
      • Knowledge can be segregated as
        • Personal – unique to one person’s experiences, thoughts or point of view
        • Local – Knowledge shared by few people
        • Global – limited, process-based
    • Wisdom
      • Accumulated knowledge is wisdom
      • We cannot create wisdom or share it, Ultimately it is an understanding that must be gained by one’s self
  • Organizing Things
    • The first step in transforming data into information is to explore its organization.
    • Traditional ways to organize data
      • Alphabets
      • Locations
      • Time
      • Continuums
      • Numbers
      • Categories
      • Randomness
  • Advanced Organizations
    • Vietnam War Memorial in Washington, DC
    • let me describe an example where the organization of data can provide an intense emotional reaction.
  • Multiple Organizations
    • Almost all organizations are actually nested, multiple organizations
      • Most Directories, Catalogs, etc.
    • “ All people learn differently and have varying skills”
      • For example, they may know the street they need to go to, but not where to find it on a map (this is where street indexes come in handy) .
  • Summary
    • Usability of an system is determined by the combination of three disciplines:
      • information design, interaction design, and sensorial design.
    • It is not possible to separate this relationship or ignore their concerns.
    • The goal of all of these processes is clear communication in appropriate forms.
    • This is done by creating compelling experiences and understanding the component of experience
  • Conclusion
    • Well written is not enough…
      • Well-written" meant things like clarity of text and accuracy of grammar, spelling, and punctuation.
    • These are essential, but the ultimate goal of ours should be to provide a good experience to the user - using our system.
