Re: Summary and Minutes of meeting of 24 January 2020

Hi Jeanne, Shawn, Bruce, Chuck,

Sorry I missed this call today, spending an inordinate amount of time in Dr.s offices seems to have thrown my schedule off, and I missed the agenda email yesterday.

To answer briefly some things I saw in the minutes:

Font: The values for font size and weight that are hard-coded for the FPWD are based on contrast sensitivity function as relates to visual angle which is embodied in the CSS reference px. Also based on readability research by NASA, DOD, FAA, Legge, Lovie-Kitchin, Stone, and others. 

VideoGames: Yes, I have reviewed research relating to video games. It is often less relevant. we are concerned about READABILITY first and foremost. If it does not show relation to reading speed, readability, critical contrast, or critical print size, such research is not particularly applicable.

IP: I want to mention that what is thus far presented is the "first step most basic approach". On the advice of my patent attorney, there is some IP that I need to make some filings on to ensure it is placed either in public domain or remains royalty free for the W3C. I have some further due diligence to attend to there.

Lookup Table & Pseudocode: just FYI, there are some minor changes that have not made their way into the google doc or GitHub, I plan to attend to these issues over the weekend. Namely, I had removed the soft black clamp from the posted pseudocode in the interest of simplicity, but in further testing, I think it needs to be there along with some slightly modified constants — these changes ARE in the live javascript example page, but I have not adjusted the pseudocode nor the github document to match. The changes are fairly minor but improve tracking and stability of results.


Please direct any questions on these or other visual readability issues to me and I will respond as quickly as practical.


Thank you,

Andy

We discussed what should go into the FPWD and the disclaimers that we want to include more automation for analyzing the fonts and font weights. We agreed to simplify that tab because the information is confusing for people who are not into color terms.  We discussed the various sources for new research in color perception and the tools being developed. We agreed that we should reach out to these groups once the FPWD is published so we can get their feedback.
