To me the 1st approach is more seducing. As you said the user can have an overview of how many results the search produced, allowing him/her to: Guess quickly if more filtering is required (quality) Figure out if the website proposes a large offer (quantity) How many time it will take to review everything (cognitive load) As Dominik said, few ...

I think you're referring to toggle switches here. That being said, Radio buttons let users select one option from two or more choices whereas a toggle switch mimics a physical switch that allows users to turn things on or off. You can also refer to these UX guidelines by Microsoft on when to use which control: Guidelines for toggle switch control ...

Start with a glass table and place it under an overhead light. Use onion paper (or some other semitransparent paper) and regular pens/pencils. Put a digital camera under the table point up at the bottom of the paper. As the participant draws on the paper, their shadow may indeed be be captured by the camera, but the point of the writing tool, and any opaque ...

You might want to consider a traditional classroom solution of using a document camera. Picture an old school overhead projector, but instead of projecting the image on the wall, it transmit digitally and you can put it up on a digital screen. Once it's in digital format, you can use any screen capture software to record this. Yes, the writers hand will ...

I don't think there's a conclusive detailed study on usage of night/day modes. I have generally seen developers preferring night mode for their editors/IDE. As an example, you can have a look at various types of night mode here - ColorSublime As far as readability is concerned, there are studies which demonstrate that dark colored text on lighter ...

Think about what it means to be staring at that loading spinner: The user doesn’t want to do any of this. He has no interest in managing his utilities. It’s something he might have to do from time to time, but he’s hardly happy about it. This had better be a smooth experience. The system has failed. Few people go straight to support without a problem ...

I love data visualisation and information experience design questions. Choosing an interactive visualisation to showcase your data is definitely a step in the right direction. We as humans, remember a lot from sight... visual and immersive content helps us understand or make sense of data we normally cannot digest. So should you really impress your ...

Look up the "Locus of Control" part of Shneiderman's "Eight Golden Rules of Interface Design" http://faculty.washington.edu/jtenenbg/courses/360/f04/sessions/schneidermanGoldenRules.html "7. Support internal locus of control. Experienced operators strongly desire the sense that they are in charge of the system and that the system responds to their ...

Nowadays mobile phones are most used interface worldwide that runs on battery. The effort to save the battery as much as possible is a challenging task for mobile manufacturers. For this purpose all mobile phones are built with LED notification lights and some use vibrations instead of fully relaying on screens. The LED notification lights only glows when a ...

There are lots of alternative interfaces Thanks to the minaturization of technologies there are a lot of alternative interfaces to the high-power LED/LCD/OLED screen in the markeet already. Voice input and input. The Amazon Echo device has a voice input/output interface capable of performing a lot of different tasks for users in a hands-free manner. ...

The Apple Watch interacts with its user via vibrations. And the user can interact with it via voice (though the screen is still active for voice input). What I find interesting about the Apple Watch's interface is how it takes advantage of multiple interaction types, including, but not exclusively, screen.

Sure. The Altair was programmed via switches, and the iPod shuffle also uses switches only. No screens in either case.

Just one page loading needed elements makes your life not easier: Seo: Isnt possible anymore as bots wont get all elements. Your websites will apear as just one single page - the starting page with its keywords. No mpre keywords possible. Thats the complete opposite of a landingpage.... Users: Cant use search engines to jump directly into your pages. They ...

I personally like something like the following (the key is small and with sort of a fading arrow) that can be found on this persons site on android arsenal I think the key is something that indicates that one can pull down which is symbolized by a downward arrow and a dotted tail or sort of a fading pattern. The tab around it is a nice touch but i am not ...

I would suggest to include (y/n) in the question itself, like this: Do you wear glasses? (y/n): If user enters a wrong answer, just display back the same question again. I believe this will be self-explanatory: Do you wear glasses? (y/n):5 Do you wear glasses? (y/n): .. What's your height? (cm):172

I agree with Paul. If you have chosen CLI, then I guess your users understand what should be entered. But manual or typo errors will occur. Humans make mistakes. Even for boolean inputs "yes" may not be accepted in place of "y". This scenario can extend to integers as well, where user might type a comma instead of a dot. The UI should let the user handle ...
