Web usability
Dark Patterns
Disguised ads: Adverts that are disguised as other kinds of content or navigation, in order to get you to click on them.
Forced continuity: When your free trial with a service comes to an end and your credit card silently starts getting charged without any warning. In some cases this is made even worse by making it difficult to cancel the membership.
Friend spam: The product asks for your email or social media permissions under the pretence it will be used for a desirable outcome (e.g. finding friends), but then spams all your contacts in a message that claims to be from you.
Hidden costs: You get to the last step of the checkout process, only to discover some unexpected charges have appeared, e.g. delivery charges, tax, etc.
-
Misdirection: The design purposefully focuses your attention on one thing in order to distract you attention from another.
-
First impressions matter: what is the most important thing here? Where to go next? Where am I? How do they call ? Where did they put ?

Usability testing
- Studies and research: identify user and investigates how the product can be used and in which circumstances
- Ideation: problems and opportunities identified by research inspires solutions -> goal of this phase
- Prototyping: identify limits and restrictions as well as the potential of generated solutions
- Evaluation: validate (in the lab / field) of the prototyped concepts with the users
5 participants, narrowed down prototypes, heuristic evaluation
