Interaction Design - I understand it as the perfect mix between aesthetics, emotion and feedback.
It's basically how things look, act and react. I recently watched a TV program about a great scientist.
The man whose curiosity led him to the discovery of the relation between electricity and magnetism - Michael Faraday. One of his quotes changed the way I look into design.
"Nothing is too good to be wonderful if it be consistent with the laws of nature"
People like an interface when it feels natural. Intuitive is a personal term though. It's slightly more specific. It could differ from people.
When Samsung released the Samsung Galaxy S3 smartphone, they had a brand new UX strategy and their focus was more on software than the cool features the phone boasted of. The user interface was focused on natural sounds, animations and tactility which sought to resemble the nature around us.
Personally I liked the idea of the Nature UX, as Samsung called it, but I feel more than giving the user a natural experience, it kinda backfired on them. I can explain how. Here is my thought on the same.
When we are familiarized with a concept and when the same is mimicked in order to provide a similar experience, psychologically, we tend to draw comparisons to the original. In this case, Samsung advertised a very earth-like, natural and gesture based interfacing platform in the form of Nature UX. When we use it, we expect a feedback and tactility similar to the original experience. However, somewhere in our head, our rational mind tells us that it is screen with a digital agent attempting to recreate an experience of which we are familiar with.
Keeping this in mind, we draw a line of expectation much lesser than what we draw when we expect a natural response to the original medium. When the experience does not touch this line, that is when we go like "Na..It doesn't really feel that natural".
When the experience a product delivers fails to make it to the the Suspension of Disbelief stage, it leads to an unsatisfactory experience. It's not like the user feel the experience is bad, but he believes it could be bettered somehow.
Ask them how, they will not have an answer.
I like such cases. Given our brain is an extremely complex component, I believe there is no single answer to this.
This is why I consider experience design an ongoing process than a definite solution to anything. There is a limit to how much we can innovate but as long as the human mind keeps growing and unfolding its secrets, there is always room for psychological augmentation through better UX.
There is no completely intuitive experience.
After all, we are only the sum of our experiences.
