Caleigh Avramis- Human Interaction 9/6

In the article Human-Computer Interaction, Dix, Finlay, Abowd, and Beale discuss how accurately understanding human perception and capabilities can help software designers create more interactive systems.

These studies consist of complex analysis’ that study human subsystems, input-output channels, and our sensories. Through our understanding of these processes, this helps create a more accurate of the model human processor. The authors show how this influences HCI with softwares and displays each of their usefulness, usability and use. This give us a better understanding of how these programs effect our cognitive behaviors and what becomes stored in our memory. These can range from temporary working memory or permanent long term memory.

Furthermore, breaking down these human processes can explain how they directly effect our HCI. For example, understanding our visual perception can show how some people read slower from computer screens than books. While this is a more negative interaction, our sensory motion to touch also has a vast importance to those who cannot see and use Braille to understand words. While there is a complexity to this interaction, the authors emphasize how its important for the progression of software designs in the future. The most efficient way to understand HCI is by understanding the usefulness of what programs are gaining more interaction online.
