My condolences on the passing of your father and thank you for bringing this to HN. I write this to further contextualize his impact. In the late 90's, my career was in haptics (touch:haptics as vision:graphics) -- at first focusing on haptic rendering of 3D scenes for virtual environments (e.g. medical, military simulation) and then landing at Immersion to make consumer devices. We leveraged Microsoft's ActiveAccessiblity feature to allow "feeling" the Desktop, an experience which, via technology transfer, is now in many Lexus cars. Both in appreciation of this technology, as well as understanding how haptics can be vital to accessibility, I represented IMMR as a member of the W3C WAI [1]. And in that role, I went to accessibility conferences. While in college, I knew some blind users of screen readers, these conferences were my first time being exposed to Braille readers, the software and hardware companies behind them, and their large community of users. I became personal friends with blind users and directly saw how this technology enabled them to be valuable contributors to teams and society. Their performance with these tools is so impressive. It's easy to forgot now with Social Media and Politics, but at that time of the rise of the Internet, the prevailing spirit was that the Internet would connect us all, independent of geography, socioeconomics, and disability. Your father's groundwork and continuing dedication prevented disenfranchisement at a time when things moved very quickly. I fear the modern Web may be leaving people behind (I have not been close to it for >20 years, so that may be baseless). I lost my father a few years ago from COVID. While I look at pictures and videos, it's really his creations and the people whose lives he enriched that I reflect on the most. I never met David Holladay, but I have witnessed his impact. Coming full circle, I recently realized that my current work in making Text User Interfaces for finance can improve access to users' financial information, via screen reader or braille device. Ironically, we are using Braille runes to allow sighted people to see graphs in text environments [2]. We will carry out this work in memoriam. Amen.
