  2. 2. Usability <ul><li>It is very common ‘term’ in software but is relevant to any product. </li></ul>
  3. 3. Why is it Important ? <ul><li>For an User: it can make the difference between performing a task accurately and completely or not, and enjoying the process or being frustrated. </li></ul><ul><li>For the developer: usability is important because it can mean the difference between the success or failure of a system. </li></ul><ul><li>For Management: software with poor usability can reduce the productivity of the workforce </li></ul><ul><li>” In all cases, lack of usability can cost time and effort, and can greatly determine the success or failure of a system” </li></ul>Contd…
  4. 4. Why is it Important ? <ul><li>Given a choice, people will tend to buy systems that are more user-friendly. </li></ul>
  5. 5. Some ways to improve usability <ul><li>shortening the time to accomplish tasks </li></ul><ul><li>reducing the number of mistakes made </li></ul><ul><li>reducing learning time </li></ul><ul><li>improving people's satisfaction with a system </li></ul>
  6. 6. Ingredients of Usability! <ul><li>Information Design </li></ul><ul><li>Interaction Design </li></ul><ul><li>Sensorial Design </li></ul>
  7. 7. Sensorial Design <ul><li>Tactile Senses </li></ul><ul><li>Visual Senses </li></ul><ul><li>Olfactory Senses </li></ul><ul><li>Auditory Senses </li></ul>Touch, Kinesthetic, Sense of Direction… Smells, Tastes Voice, Music, Sounds Writing, Photography, Typography, Graphic Design, Iconography, Animation, Illustration & so on.

It has been around for hundred of thousands of years. It is merely new to electronic media. </li></ul>Contd…
  9. 9. Interaction Design <ul><li>Components of Interactivity </li></ul><ul><ul><li>Feedback (Responsiveness) </li></ul></ul><ul><ul><li>Control (Navigation, Accessibility etc.) </li></ul></ul><ul><ul><li>Productivity (Creation Tools) </li></ul></ul><ul><ul><li>Communications (Discussion Forums, Chat, Storytelling Engines etc) </li></ul></ul><ul><ul><li>Adaptivity (Customization, Personalization, Psuedo-Intelligence, etc.) </li></ul></ul>
  10. 10. Information Design <ul><li>What is Data? </li></ul><ul><ul><li>Data is the product of discovery, research, gathering, and creation. </li></ul></ul><ul><ul><li>It is the raw material we find or create that we use to build our communications </li></ul></ul><ul><li>To have informational value, it must be organized, transformed, and presented in a way that gives it meaning. </li></ul><ul><li>So, Information Design is all about Organizing & Presenting the data into a valuable & Meaningful information </li></ul>Contd…
  11. 11. Information Design <ul><li>The trend is transiting from Age of Data to Age of Information </li></ul><ul><li>It is imperative to know which media work well for what kinds of messages: </li></ul><ul><ul><li>text, sound, voice and music, animation, video, illustrations, photographs, and diagrams, video, and other forms </li></ul></ul>Contd…
  12. 12. Information Design
  13. 13. Knowledge & Wisdom <ul><li>A bit on Knowledge: </li></ul><ul><ul><li>The information when experienced provides Knowledge. </li></ul></ul><ul><ul><li>The knowledge is communicated through compelling interactions </li></ul></ul><ul><ul><li>Knowledge can be segregated as </li></ul></ul><ul><ul><ul><li>Personal – unique to one person’s experiences, thoughts or point of view </li></ul></ul></ul><ul><ul><ul><li>Local – Knowledge shared by few people </li></ul></ul></ul><ul><ul><ul><li>Global – limited, process-based </li></ul></ul></ul><ul><li>Wisdom </li></ul><ul><ul><li>Accumulated knowledge is wisdom </li></ul></ul><ul><ul><li>We cannot create wisdom or share it, Ultimately it is an understanding that must be gained by one’s self </li></ul></ul>
  14. 14. Organizing Things <ul><li>The first step in transforming data into information is to explore its organization. </li></ul><ul><li>Traditional ways to organize data </li></ul><ul><ul><li>Alphabets </li></ul></ul><ul><ul><li>Locations </li></ul></ul><ul><ul><li>Time </li></ul></ul><ul><ul><li>Continuums </li></ul></ul><ul><ul><li>Numbers </li></ul></ul><ul><ul><li>Categories </li></ul></ul><ul><ul><li>Randomness </li></ul></ul>

  17. 17. Summary <ul><li>Usability of an system is determined by the combination of three disciplines: </li></ul><ul><ul><li>information design, interaction design, and sensorial design. </li></ul></ul><ul><li>It is not possible to separate this relationship or ignore their concerns. </li></ul><ul><li>The goal of all of these processes is clear communication in appropriate forms. </li></ul><ul><li>This is done by creating compelling experiences and understanding the component of experience </li></ul>
  18. 18. Conclusion <ul><li>Well written is not enough… </li></ul><ul><ul><li>Well-written&quot; meant things like clarity of text and accuracy of grammar, spelling, and punctuation. </li></ul></ul><ul><li>These are essential, but the ultimate goal of ours should be to provide a good experience to the user - using our system. </li></ul>
