comment An intuitive way to look around in web based first person 3D
In the human factors literature, the principle you are asking about is response-effect compatibility. This article is relevant to your question.

comment What are best practices of algorithms for suggesting products in auto-suggest search pattern?
The inputs into a recommender depend on what you are recommending. Inputs can be explicitly requested from your use or implicit, I.e., behaviors you believe indicate interest in a product or associations between product. Product attributes that create groupings of products depend on your own model of what is important about a product. For example, 'product color' might be useful for recommending paint but not for recommending books. Start reading here for an introduction.

comment What is the difference if any between increasing font size on a high res display and using a normal font size on a comparatively lower res display?
The benefit (if any) of a higher resolution display depends on the task. See 1 and 2 for examples. The earliest research on this question compared digital displays to paper. It's a big topic. This is a good place to find more recent research.

comment How much computer literacy user should be expected to have for using an ERP?
Microsoft has published research on designing user interfaces for illiterate and semi-literate populations in emerging economies. It might be relevant to your problem. See this and this for a start.

Build a prototype on CogTool. This will give you task completion time estimates.

comment How to handle roles access permissions
Another option is what SharePoint does - display a message saying the user does not have permission and provide a link that will request access to that section of the site.

comment how to feel on touch screen
There are many ways of communicating shapes and textures on a touch screen device. A good starting point for learning about this technology is Disney Research.

comment How many characters to show before truncate a review on mobile device?
For example, the average comments length on Stack Overflow is 146 characters. The truncation rule for those comments would be different than the truncation rule for a product review on an ecommerce site - assuming the reviewers are more verbose.

comment Universal Human-Interface Guidelines
The US Department of Defense has produced MIL-STD-1472 that is supposed to be independent of any platform. Another document worth reviewing (although it is quite old) is Boff & Lincoln Engineering Data Compendium Human Perception and Performance. Search for Boff Lincoln here and you will find links to pdfs for each volume. I would link directly to them but the documents are >100MB each.

comment Color choice for maximum legibility of text on glass
There has been quite a bit of human factors research on a related problem: HUDs. Similar to text on a glass door, HUD symbology is presented against a changing background. As you would expect, the legibility of HUD text and symbols depends on more than the text color. The other source of research on this topic is from the earlier days of the web. This paper is a good example and available for free. It cites some of the HUD research.

comment Standards for and measuring contrast of solid color fills
Two comments: (1) In the example images on SO Meta, white is the background which means the foreground-background contrast tools will work for your purposes. (2) ColorBrewer will help you find colors for large area fills. It is based on color perception research in maps (i.e. solid fill colors in adjacent areas). You can find the papers describing the research here.

comment Should I ask the user to enter their age or their birthday?
@FighterJet: I was not convinced until I read the last sentence in your comment. Now I know you are right. Brilliant argument! However, please explain how collecting date of birth satisfies the Legitimate Purpose and Data Proportionality principles of the EU's Data Protection Directive. The app needs the user's age - not DOB. Collection and storage of DOB, being PII, is the subject the Data Protection Directive. The UX designer should know this and adhere to these principles. The question asked by the UX designer is either naive or willfully disregards data security of PII.

comment Should I ask the user to enter their age or their birthday?
This is not a UX question. Rather it is a data security question. Date of birth is definitely PII. Age is less so. You should not collect date of birth unless your service cannot operate without it and you can guarantee it will be stored securely.
