I became a guerrilla UX fighter back in 1995.

Me in my guerrila days

I've been underground for many years, but recently decided to ditch the Kalashnikov, get out the trenches, and take a more formal approach to the topic.

Currently taking an MSc in Human-centred Interaction Design at City University, London.

I specialise in complex system, cognition and aesthetics; my current role is a UX/Product designer.

comment How to show the relationship between two input fields with different units
Why use a combo for two options instead of radio buttons? It's 2 clicks with low visibility, vs 1 click with high visibility.

comment Are buttons perceived as rectangles first?
Although I see where you are coming from, I wouldn't rush to conclude a button saying 'post' is unclear without knowing what the app actually does, who uses it, and what other actions are available. On a smoke detector a button saying 'Shhhh...' would be crystal clear to most people - context plays a massive part in cognition.

comment Which part(s) of the overall user experience is best represented by the NPS?
You can argue that ones recommendation for a peer is the outcome of functionality, reliability and usability of the system, but one that is much more due to emotional response than a conscious reasonable one.

comment Why most web designer don’t embed the image sizes in the html document
Aye - it's dynamic loading rather than image sizes.

comment Why most web designer don’t embed the image sizes in the html document
I don't think this is a UX question - more of an implementation question. Anyhow, I don't really understand the problem... could you provide a reference to a page where this happens? This seems to be a dynamically loading images issue rather than a size issue. But I can't be sure as I'm not really sure how to replicate this issue or where.

comment UX to view and search through large set of hierarchical data
@myradon Not sure I understand the question. Consider a tree with all nodes/leafs shown. Now in the query field the user types 'a'. Say it isn't flex-search, so only items starting with 'a' are considered matches. Basically, any non-match is hidden (taken away from the tree). Does this make sense?

comment Four states, one checkbox - any way for it to make sense?
@DA01 You're right - radio buttons are for a single choice, not multiple ones. Wasn't attentive enough with the terms but I'm afraid I can't edit the comment now. Thanks for spotting that.

comment Four states, one checkbox - any way for it to make sense?
Just to expand on this answer: Checkboxes should be used with yes/no questions. For multichoice you can either use a select(drop down) - less space but less option visibility; or use a radio button group.

comment User options - selecting the right control based on the number of options available
This one will be hard to answer without more details - sometimes a radio group of 5 options is the right solution, sometimes a dropdown. How often users switch? Where in the interface the options show (is space an issue?), etc.

comment Is there a better way than zebra stripes
This answer is nearly as good as it gets. I just feel I should add that zebra-striping is essentially an implementation of Gestalt's law of enclosure. From visual design perspective very pale, low-contrast background will do the job - both in the OP image and the one on this answer you could argue that the grey raws can be toned down yet achieve the same effect.

comment Close button place depending on OS
"one of the points of creating a web application rather than a native application is for cross-platform portability" - I see where you're coming from but this is a dangerous argument. Following this logic, a Save keyboard shortcut on a web application should always be CTRL-S even for Mac users who use CMD-S. Portability should follow usability, not the other way around.

comment Forms: pattern to create/convey dependencies between fields?
Also, any one can use a line of text. Making this interactive would require users to learn how to achieve such task.

comment Forms: pattern to create/convey dependencies between fields?
Have a look at this image showing a simple equation in a graphical form (quite a bit of genetic AI uses this type of notation). You are probably to end with something similar to the graphical form on your interface (replacing the * and + signs with AND and OR). I'd ask myself which notation is clearer - the graphical or the plain textual one?

comment Forms: pattern to create/convey dependencies between fields?
I can totally understand, but it's worth remembering that sometimes a (visual-)verbal form is easier to interpret than a pure visual one, and I suspect that such might be the case with logic. One visual solution would be to allow users to select questions, group them, apply a logic operator (AND or OR) than ditto for the groups - essentially creating a visual hierarchy. But doubt interpreting this would be easier than a simple logic line of letters and brackets.

comment Forms: pattern to create/convey dependencies between fields?
I can think of various ways to achieve this, but if honest (and considering a really complex logic some may wish to have), I doubt any will be better than simply providing a test field to type in the condition as they would in a programming language. For instance, the pass condition field may have the value A and B and C and (D or E or F). You can obviously go further and provide more natural syntax like so:A is correct and B is correct...

comment Organizing UX bookmarks folder
This question appears to be off-topic because it is not really about user experience; it's about organisation of articles, and many opinions may appear here, with no definite answer.

comment Visual feedback of “no new data” after pull-to-refresh
Here's some interesting theory to why people do this, and possibly why providing a feedback may not help here.

Just out of interest, how exactly do you se the model?
