Interaction is defined as a dialogue or a relationship between people and objects, systems, spaces, and services. It happens on a daily basis with everything designed around us.

To begin my exploration with Interaction Design, I am starting with the basic type of interaction, the most common thing we do when interacting with a system or object is pressing buttons or clicking. This kind of “input” manifested by pressing the buttons is performed by us “the users” to the system, requesting it to perform a “function”.

Some of the daily examples portrayed in the photos below are iPhone Home Button, AC Remote Control, Water Dispensers, and Light Switches.

What makes these interactions effective?

As part of this exploration, for our course on Cognitive Science of Interaction Design, we discussed a few factors to consider if an interaction is good:

  1. Discoverability — The ability to understand what operation can this object or system do
  2. Usability — The ease of use of the object at hand
  3. Feedback — The reception of signals of what happened
  4. User-Centered — Intentions or needs or goals are met
  5. Emotional Qualities — Understanding the emotional qualities of what is designed

To understand more these qualities, the below model “How do you…feel-know-do?” Created by Bill Verplank presents a classic feedback loop to portray the relationship between the user and the system through “Feeling” and “Doing”.
