Applications of HCI[1]
Human-computer researchers are assets to a number of organizations that develop mission-critical software, Edmunds says. The Federal Aviation Administration, for example, employs an HCI division that studies control towers. Before making changes to the color or the font used in the air traffic control software, they perform rigorous studies to understand how the changes might affect the users. Otherwise, Edmunds says, software changes without the proper research and testing could be disastrous. While other organizations may not dedicate an entire division to HCI, the principles derived from it are applicable to a number of jobs. For example:

  • Product developers may use HCI methodologies to better understand the user of a new electronic device or software the company is planning to launch.
  • User experience developers may employ HCI research to make sure the company’s website or advertisements encourage customers to buy.
  • Data scientists may study HCI to develop data visualization dashboards that best convey information in the most usable way.
  • Software engineers may employ HCI research when developing revolutionary products for new audiences.


HCI Best practices[2]

  • Make elements in your interface legible: If the characters or objects being displayed cannot be perceptible, they cannot be used effectively.
  • Redundancy is important: If a signal is presented more than once, it is more likely that it will be understood correctly. Redundancy does not imply repetition. A traffic light is a good example of redundancy, as color and position are redundant.
  • Similarity confuses: Use distinguishable elements. Signals that appear to be similar will likely be confused. Unnecessarily similar features should be removed and dissimilar features should be highlighted.
  • Use multiple resources: A user can more easily process information across different resources. For example, visual and auditory information can be presented simultaneously rather than presenting all visual or all auditory information.
  • Replace memory with visual information: A user should not need to retain important information solely in working memory or retrieve it from long-term memory. A menu, checklist, or another display can aid the user by easing the use of their memory.
  • Don’t reinvent the wheel: Old habits from other interfaces will easily transfer to support the processing of new ones if they are designed consistently. A design must accept this fact and use the standards already used in similar interfaces.
