Human Computer Interactions

Human Computer Interactions A pragmatic approach to interaction modeling is presented by which a designer can describe how the user gets tasks done with a newly developing system. The notation proposed allows an interaction designer to make explicit both how user actions cause visible or noticeable changes in the state of the machine and how the user is expected to use feedback to generate their next action.
Answers the following questions:

  • Specifies the visible system state that leads the user to take some action.
  • Makes explicit the state of the goal stack at the start and end of the unit and the mental processes (recall, recognition, or affordance) required.
  • Can describe the intimate connection between goal, action, and the environment in user-machine interaction.
Provides the following benefits:

  • Demonstrate the completeness of Human Interaction scenario analysis
  • Models can be presented for some well-known problems in interaction design.
  • Ensures the target will accept or use site features or other elements.

Human Computer Interaction is just in it's inception phase currently, although it has been a long standing practice in the Information Architect domain, validating the practices of many Architects the world over. Eye movement tracking has been successful in validating that users are more attracted to buttons and pictures and will read these first, and studies about Usability have proven that websites with more than three deep pages will just not do. Users in the modern era of Search engines are more apt to Search a site than meander down a list of sub navigation to an even further list of possibilities.With the introduction of Iconography, and the widespread use of it throughout the internet and in OS applications, companies are starting to see the usefulness in utilizing it to increase the speed and ease of buying and checking out on their websites and in their web based applications. Iconography has always been a religion I live by! Just think about how that MS “Word” icon on your desktop lets you know intuitively that you will open Word and begin. Notice the way you identify and use icons everyday in your world and you will see a whole new way of short hand communication that proliferates our lives. From the Starbucks brand, to the PDF icon, it all lets you know something in the most shorthand way of speaking to your brain there is, Iconography.
