comment Is there an intuitive way of creating Boolean rules without requiring knowledge of Boolean logic?
There are several questions in UX SE already that are related to this question.Intuitive interface for composing boolean logic. Good solution for boolean filters.Does the average web user know about Boolean algebra

comment Color Emotion Naming Convention Standard?
Part II - Examination of the relationship between Pleasure-Arousal-Dominance model of emotion and hue, brightness, and chroma. See page 402+. Similar research using valence-arousal.

comment Color Emotion Naming Convention Standard?
Part I - There is (almost) a century of research on this topic. As Aadam points out, there are cultural differences in the meaning of color. However, 'meaning' and 'emotion' are not the same thing. I'll attempt to answer the question as it is posed where mood is related to emotion. First, the relationship between emotion and color depends on your model of emotion. Second, 'color' can be broken down into hue, chroma, and brightness. The rest of my comment references research into this topic. Whether the UI framework color names are based on this research is unknown.

comment Why are messages on the road printed in reverse?
Part II - Putting the words in traditional order would mean one of two things: (1) assume constant letter size - the driver will be past the words at the end of the message by the time the driver needs to read the message, or (2) assume letter size variable letter size - the words at the beginning of the message would have to be much larger than the words at the end of the message because the words at the beginning of the message have to be readable sooner and from a larger distance than the words at the end of the message.

comment Why are messages on the road printed in reverse?
Part I - The minimum recommended preview time is 3s. See page 20-2. Guidelines for the minimum visual angle of horizontal signing are described here on page 3.. These two values and the average travel speed of a vehicle on the road where the sign appears gives you the reason for the reverse ordering of words in a message.

comment Do signs printed on the road offer a significant advantage for the user over signs on a post?
Part II - Look at the values in the % Change column in the section titled 'Signs'. The negative values in this section indicate greater effectiveness than the pavement marking signs referenced in the other section. This means the pavement marking signs were more effective in getting drivers to obey the posted speed limit but enhanced road-side signs were more effective than pavement markings.

comment Do signs printed on the road offer a significant advantage for the user over signs on a post?
Part I - The answer to the question is 'Yes, signs printed on the road offer a significant advantage for users overs signs on a post' in certain conditions and when 'user' means 'anybody that benefits from drivers obeying the speed limit.' This is a summary of speed countermeasure research up to 2009.. Look at the section titled 'Surface Treatments and Markings'. The values in the % Change column are negative (mostly). The negative values mean drivers reduced speeds compared to the baseline, i.e., signs on a post.

Pavement markings (which is the phrase you want to use when searching for this topic) are effective in controlling driver speeds. See page 14 of this research summary. The reasons for using roadside elevated signage instead of pavement markings are mentioned in the research too. The answers below cover most of those reasons.

comment How best to provide contact info in a member directory while preventing 'data harvesting'?
Agree. None of the ideas will keep anybody that values the data from getting it. Regarding the 'Encrypt customer IDs in the URL...' You should not put anything in the URL that has any tie to authentication or contact information anyway. Regardless of your scheme for keeping unwanted visitors away from the contact data, do not put a customer ID in the url. (You probably know that but including it in the list suggests the ID might appear in the URL.)

comment Is the state of 'flow' equivalent to user engagement?
According to the researcher most active in the investigation of user engagement (UE), UE and flow are not the same thing. See page 24 for a comparison of flow and UE. This paper describes a comparison of UE and Flow measurement scales. They conclude the two constructs are distinct.

comment There is some research done about cognitive workload vs 3D movements?
There has been research on the mental workload associated with 3D displays. Examples include controlling a surgical robot, identifying places in the human body, and flying an airplane. 3D displays are associated with lower mental workload in the first 2 situations.

Unless you are asking about mental workload associated with 3D displays, perhaps you should ask the question at Cognitive Science Stack Exchange. If you are asking about 3D displays then see my other comment.

comment How long does it take a user to find and click an object in a list?
You can simulate the actions and get time estimates using CogTool. It is based on ACT-R and some form of GOMS.

comment How do users react to a browser request for geolocation?
@EvilClosetMonkey Understood...and the ubiquity of web site's detecting a desktop browser location without asking permission was the source of my question. When would asking permission to do something most sites do already be necessary? I do not understand the context in which this question would be asked.
