2. Usability vs User Experience
Usability; ease of use
User Experience; usability + function + beauty + charm + story
3. Usabilty
Usability is the ease of use and learnability of a human-made object. The object of use can be a
software application, website, book, tool, machine, process, or anything a human interacts with.

4. User Experience
User experience (UX) is the way a person feels about using a product, system or service. User
experience highlights the experiential, affective, meaningful and valuable aspects of human-computer
interaction and product ownership, but it also includes a person’s perceptions of the practical aspects
such as utility, ease of use and efficiency of the system. User experience is subjective in nature, because
it is about an individual’s feelings and thoughts about the system. User experience is dynamic, because
it changes over time as the circumstances change.(Wikipedia)
7. Interaction Design
In design, human–computer interaction, and software development, interaction design, often
abbreviated IxD, is "the practice of designing interactive digital products, environments, systems, and
services." Like many other design fields interaction design also has an interest in form but its main
focus is on behaviour. What clearly marks interaction design as a design field as opposed to a science
or engineering field is that it is synthesis and imagining things as they might be, more so than focusing
on how things are.
Interaction design is heavily focused on satisfying the needs and desires of the people who will use the
product. Where other disciplines like software engineering have a heavy focus on designing for
technical stakeholders of a project.(Wikipedia)
8. Progressive Disclosure
Progressive disclosure is an interaction design technique often used in human computer interaction to
help maintain the focus of a user's attention by reducing clutter, confusion, and cognitive workload.
This improves usability by presenting only the minimum data required for the task at hand. The
principle is used in journalism's inverted pyramid style, learning's spiral approach, and the game
twenty questions.(Wikipedia)
9. Von Restorff Effect
The Von Restorff effect (named after Hedwig von Restorff), also called the isolation effect, predicts
that an item that "stands out like a sore thumb" (called distinctive encoding) is more likely to be
remembered than other items.
For instance, if a person examines a shopping list with one item highlighted in bright green, he or she
will be more likely to remember the highlighted item than any of the others.(Wikipedia)

10. What We Should Ask?
"If I asked my customers what they want, they want a faster horse" H.Ford
Instead of asking consumers what they want, ask them what's going to disturb them and what will
make them happy, and then design the product according to the data.
