comment How does the visual size of a text input field affect users' expectation of how much they should write?
Research on survey design has been looking at this type of problem for a while. Social Science Computer Review is full of research on the effect of input widgets on response rate and quality. This is an example that is not behind the pay wall. In the context of online surveys, field size does affect the response. It can change the response format (see Couper 2001 in SSCR). It can depress response rate.

comment Should a user be informed if their Do Not Track request is honoured?
I'm assuming that '...honours the DNT requests...' means the visitor has set the browser to 'do not track.' Clarifying because the DNT can be set to 'track me.' If a site honors DNT then each session for the same visitor would trigger a "not tracking you" message. Right? Also, a 'site' is many servers. Not all are directly under the site's control. All servers will decide whether to honor the DNT request. This makes a single message from a site potentially meaningless because some servers will honor the request while others will not.

comment When is using haptic feedback for button presses a good idea?
Haptics in mobile devices is complex. Are you asking about haptics in specific applications like IM, games, or accessibility?

comment research: dark or light UI better outside
This model of daylight readability assumes negative contrast polarity will degrade readability. See page 24. This research on legibility manipulated several factors including contrast polarity. They summarize the effect of the color-related factors as 'Color difference was found to play a minor role in legibility under daylight ambient conditions.' I do not have access to the full paper and am unable to provide more details about the effect of contrast polarity in detail.

comment Thermostat UIs make me guess and think too hard
There is research on thermostat usability and mental models. See Kempton.Me‌​ier.Peffer.Sachs.

comment Studies on the efficiency gains of Vimium-esque keyboard shortcuts
Yes. This has been studied and this type of UI improves learning and use of hot keys. However, the results of the research may be influenced by demand characteristics of the experimental setting. A field study would be more conclusive. MS may have done that type of research because Office has this type of UI for showing hot keys. The same authors wrote this paper which explains the problem of learning 'expert techniques'.

If you are searching for more references, use the term 'display polarity' as shown in Table 1 and this abstract from recent research on this question.

comment Studies about negative readability
The author of this research wrote "Some evidence for an effect of halation was found in the current experiment. The mean RT for light text on a dark background was x=17559.24, while the mean RT for dark text on a light background was x=16909.33." This is not the same as "there is limited to no evidence that black text on White background is have higher redability than white text on black background" as suggested by the answer above.

comment A/B testing in user test
Good summary of within-subjects experimental design. Here are a couple of references ref1 ref2 on threats to internal validity of that type of design. As the second reference says - this type of design is common in behavioral science research.

comment Do you know any good source for human-robot interactions?
Georgia Tech has a lab looking at the area of research too.

comment What do dark and light dashboards communicate to users?
I agree. RPG is one example of a culture with color preferences. A related question was asked last year. The answers touch on some of the data found in research like this.

comment What UX guidelines should one keep in mind when designing the GUI for a automobile center stack/console?
Try 'human factors', ivis, 'driver performance', 'driver distraction' as a starting search. The research methodology also provides useful search terms: 'occlusion protocol' 'occlusion method' driver 'secondary task'

Before you start, please familiarize yourself with the research in this domain. The OEM probably follows the standards and guidelines created by organizations that do research on this problem.

comment Is there any attempt to standardize a “cancel” action in elevator buttons?
This question may be a duplicate of a question asked 2 years ago.. Also, a column in Forbes about this question.

comment What is the most intuitive way to rotate an object in 3D space
This is the oldest research on this topic.. These 1 2 are more recent. The ideas you mention have been tried. The 'best' interaction depends on the task.

comment Would it be risky to gamify school?
Yes. I would gamify learning because [it has already been done] (intellimedia.ncsu.edu) and done well. That's not the same as gamifying school but school is much more than learning the subjects being taught.

comment Colour stripes in chart
This research suggests there is no performance penalty for pattern coding compared to color coding of bars in a bar chart. There is a difference is preference for color coding over pattern coding.

comment How to measure the difficulty of a question
Item-response theory and test development are the place to find more information. In the U.S., ETS is a test development organization. This is a link to a page on their site explaining test and test item development. Click on the Watch Now link (next to the big Q) for a video about evaluating questions in a test.

comment Are Visual Programming Interfaces effective for non-tech users?
I agree based on my experience with visual languages in a few domains. They work OK but there are other representations of process logic that work equally well. @Abektes, one point of confusion in a visual/diagrammatic language is the meaning of nodes and connections between nodes. You need to decide (1) whether nodes are objects, processes, or the result of a process (a system state) and (2) what the connection between two nodes means. Not surprisingly, people interpret diagrams differently and the meaning of nodes and connections is, often, at the root of the differences.
