One of the last lectures of my online Human-Computer Interaction (‘HCI’) course by Scott Klemmer was all about “mental models” and their role within HCI. The proposition that people rely on mental models was first introduced by Scottish psychologist Kenneth Craik who wrote that the mind constructs “small-scale models” of reality that it uses to reason,…

Learning more about direct manipulation and reducing the ‘gulfs’
“Direct manipulation” is one of those Human-Computer Interaction (‘HCI’) terms that sounds intriguing. During the online HCI course instructed by Scott Klemmer which I did recently, I learned a bit more about what direct manipulation means. Direct manipulation is a HCI method which involves continuous representation of objects of interest and rapid, reversible, and incremental actions…

Heuristics – Finding usability problems in designs (part 2)
In my last post I wrote about the use of heuristics to find usability problems in designs. In this post, I’ll look into the individual heuristic principles in more detail. It was UX expert Jakob Nielsen who introduced these “10 Heuristics for User Interface Design” in 1985 and these principles serve as a great context to…

Heuristics – Finding usability problems in designs
As part of my online Human Computer Interaction (‘HCI’) course by Scott Klemmer, I learned a lot about “heuristic evaluation”. Even though I had heard the term ‘heuristics’ used before, I had no clue what this entailed. In his online lecture, Scott explained that heuristic evaluation is a method one can use to review user…

Rapid prototyping – Storyboarding, paper prototyping and digital mockups
In a the online Human-Computer Interaction course that I did recently, I learned quite a bit about “rapid prototyping”. As the name suggests rapid prototyping is all about mocking up ideas quickly, to get user feedback fast. In the lecture on this topic, Scott Klemmer – an Associate Professor of Cognitive Science and Computer Science &…
