What is User Experience (UX)?

Why do we need to learn  Interaction Design (a subset of UX)?

UX vs Interaction Design
  1. We need skills and the knowledge of how to design products and services that are more efficient and pleasurable to use.
  2. An understanding of both the human user and user experience is the key to limiting, and potentially eradicating all of the frustrating, time-consuming and poorly designed technology in this world. These poorly designed technologies restricts our productivity and sometimes even test the limits of our sanity.
  3. An understanding of the user and their limitations, capabilities and quirks is imperative to aid you in your task of designing products free from the mistakes committed by your competitors, so you can get one step ahead of the pack.
  4. Designing a technology which is very user-friendly is always a good thing. This ultimately improves everyone’s quality of life, your end user’s as well as yours as a successful business owner when you will have so many happy customers.


The three key pillars of a successful interaction design are:

  1. Understanding the technology
  2. Understanding human psychology and sociology
  3. Finally, understanding the relation between first two, technology and human psychology and sociology.

What is Computer Vision?

We use our eyes to figure out how fast we are moving relative to other objects in the immediate surrounding, to figure out where are the lane lines and where do we need to make a turn exactly. We use our eyes to perceive the world around us. Eyes are the sensors and our brain the system that takes in the signals from our eyes and finally helps us make sense of what the eyes capture. There is no vision without the brain. Without the brain, it’s just some data, an input signal with no interpretation.

Likewise, Computer Vision is a system of sensors (Camera, LIDAR etc) and algorithms (image classifiers using deep learning, image analysis etc) that helps make sense of the signals coming from these sensors.

Another aspect that is also important to mention is “Vision” here mean two different things:

1. Making sense of the scene in front of you. Already explained above.

2. The prediction. In the sense that Steve Jobs was a great visionary. He was able to see the future, like what’s coming. Here, a good example would be the system that the Predator had in that old movie, which he used to predict the trajectory of an object thrown at him and then he used that predicted trajectory to shoot it down in mid flight. The Tesla auto-pilot predicting a crash is a perfect example of such a vision system.
