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 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.

comment How do users react to a browser request for geolocation?
What does 'request of geolocation' mean? On the desktop, the client location can be determined by the IP address in the request header. In a mobile app, the location can be determined in several ways.

comment Cognitive strain by reading data in tables?
There is plenty of research on the effect of the difficulty of acquiring information on decision making. A simple summary is 'If the user can make a decision without the information and the benefit of acquiring additional information is outweighed by the difficulty of acquiring the information then the user will make the decision without acquiring additional information.' In the situation you describe, a table that is difficult to read may be ignored unless it is the only source of information on which to base a decision.

comment Original design choice of back and forward directions?
While reading an answer to this question, I saw the reference to Olsson. Is there any evidence that Olsson designed these controls? I've found nothing to support it.

comment What is the origin of the eject symbol?
Agree the symbol suggests movement. In the context of a cassette player, the horizontal line is the cassette and the arrow suggests movement of the cassette up, i.e., out of the play loop and into the hands of the operator.
