Okay. Thanks for any few minutes late. I've been acting as I T support as well for the other room. So I'm running back and forth. I work for Adobe Lightroom Adobe document Cloud for a long time. And that's kind of what I bring to these meetings this affect the stability. So it may be a little bit strange to see me onstage not talking about accessibility because that's usually my mission particularly responsiveness and personalization of content. I'm hoping this time together.
How do you say? I'm trapped in this presentation. Custom mine back 26 years. So I think everyone probably knows just stopped on June 15th 1993 with the release of act 1 PDF for The Camel up project several years before that fundamental problem that confronts today's company's ability to communicate. I think we can all say the PDF is being a great success if you think about how it's a huge success and so that's that's a very positive statement. He is a sense PDF
first became available to the public. This is a hugely successful project. However, it was designed and the public was being solved was what I would refer to this is Lil peep a problem the ability to take content may be the other way around. Content Faithfully with all of its imagined. I just want a repeat that no one saying PDF fail today. It's a very very different platform. We have different screen sizes. What I refer to you from watch to wall Mouse trackpad are the touch screen with I'm using oil and punches to talk to my
Amazon Echo or Google home. I'm so it's not the PDF did anything wrong? In fact vs is a real success story. But I do believe that if we don't continue to adopt, it won't necessarily be that big a success story in the future. It's not going to go away. What is the great question as yesterday? Where does pee come from? Pdfwhiz me successful because of his concert of this longevity. They both meet very differently. But PDF is one of being able to to convey that consistency. And so if we do
continue to build them PDF has to retain all the way into the future. I'm telling for PDF PDF. So we've used our secret PDF printing to PDF not converting of creation PDF for printing PDF printing is actually had a very harmful effects on PDF because what it means when you doing I don't think that's a very positive property, but it doesn't mean you lose something. You don't have to just be natural for the low-cost way to produce PDF is being to go for the taking a GDI streaming into a
visual layout whether it's actually having the underlying rendering engine of your Heroes quote. Into the file be the challenges we face in PDF today. So some of the solutions let me just explain why I think this is the problem. Responsiveness very quickly break down if I convert a really quite good scientific journal magazine know I do have hopefully a video here just to have highlight some of the things that I want to just frame this video. This isn't intended to show a success story. This isn't
failure either. It's just this is a this is the iOS version. Most people don't see it because the screen sorry. Hocus Pocus deleted all say let me restart that. Okay, let's try that again. So, you know a lot to consume this content very simple man is just flowing that confidence into a container if I pinch and zoom at least sizes the content for the container some of the aspects of the imagination is doing the bad minimum needed to basically allow us to to to to to solve the problem of at least 15 onto a phone but that's a really great experience only if it does address one
problem solve one problem alone, which is the responsive side of things the reading of it. We have several speakers today talk about math and the ability for map to be understood the datasphere the document if you think about how you have responsibilities in that maybe it is a matter of your teacher allowing your mouth to be displayed at the Highlight. What's being read as your screen be the reason that may be for 80. I'm not a great reader in natural language. I would like to know
if we do math into display math and two if they even got a match weed, does it work for them vda that use methanol to to display a tilite mathematics if it's just drawings on the page, you can't do that. And so you need that rich rich date that I reach semantics in the PDF to achieve that I know it's not just about the youth in the visual appearance of the screen. I'm not communicating with devices both verbally because I'm speaking to him speaking back from Yardley maybe a phone if maybe Siri this maybe some of the assistant
received a business report by email. I want to listen to make a speaker and go so it's not just about your these simple use case in this way. It's not just about accessibility accessibility is really important things that everyone can benefit from How PDF can play a role in that but I don't think we need to figure out how to put more detail earn more semantics in pedia. So that's a little stamps unresponsiveness. You're the part of my personalization. What do I mean by personalization? So there are many types
of fonts in the world and we had this morning and one of the about how is this once a pretty difficult is really painful if I've being deprived of all my phone cases that I like that no one can change them Father then I'm locked and I have to build one copy of the document. But if I don't know if I can consuming differently things much much more accessible while also returning all the visual Fidelity. I wanted to put it in the design of a technical designer who
can actually do that come from So what am I comfortable to read? Isn't that what everyone else finds comfortable to read 10 years from now what I find comfort in college and read have the basically they got the biggest money for the times of mass of 20. What is the largest size? You can read it for PDF this week because you have to move back and forth through this document reading it so nicely comfortable to you depending on the size of the screen on this playing on can be very different as well. It doesn't have to just be it's the context was which I'm
viewing the material as much as it is the specific. Give me up after abuse 11 individual. The Benson studies of late about reading speeds and the ability for people to consume content and they shielded actually in varies a lot from person to person things like character spacing in a huge impact on reading speed and comprehension happened to clean pool filter be visited some of the properties of the studies of used many different characteristics of typography to understand how you can
choose time for a layout this going to start your entire audience. So how do you address that? You know, how do we solve the biggest challenge facing PDF? We do need that visual Fidelity just to be clear this there's no doubt. The PDF says she's purpose in having that base layout. Sepsis, but I'll maybe I'll 3 that the video Fidelity fix content final form is the term that would be using the size of the screen the nature of the use of the needs of the device. How do we
actually address this face? And I think this is this is the biggest challenge in the biggest thing that so Actually, I'm going to prevent pollution today. There is no one solution is that there is no one-size-fits-all solution for each of these individual problems, but I do want to just the whites challenge for PDF. So I talked earlier about printing to PDF and other say that's a very common scenario. I take the visual materials. Are you in today? If you use all the systems and it converts
advice Independence lamp to lose all the bridges semantics of the original content of any visually LazyTown into PDF. I'm about to be a pretty horrific 7-step process. What what you got to be in his new knowledge of what was that in the beginning? What is even worse just because a lot of systems just don't even think about semantics in the first place. They don't even know about that lot that there's a level of cement is a little document systems that
impacts the don't rely on just printing to get to the PDF. so that's the way it's really not so we've had a bit about one of the solutions PDF. So if multiple large instructions pdf was introduced in 1999, the tank says that came in 2001 for a long time does the Franklin is someone in that 15 to 20% of the market today is actually a pretty good. I mean to say how hot it's just the fact that people people say 1520 Seminole Trail of but given how easy it is to print to PDF and how hot it is. Actually we need to continue to Bill
value on it because until now Golden PDF is how do we continue to build features that are available to everyone What flows than an 8-ball potential or immediate compliance go by doing this they may help moving things forward, but they're not going to be enough as I think to really deliver a future of intelligent documents. Picture of little bit on the fundamental issues the PDF faces though. He is a standard PDF Pages. It looks better on my screen. Basically. Let's just look at one paragraph. So we'll we'll move in a little closer
so we can actually see what's in my contacts when I'm laying out this is content in a PDF. I'm just drawing list to a page. I'm just painting at location on the page. I could decide to print all the confidence with all the vowels all of One phone before another fun. It's up to me the author all the offering systems inside how to compose that as long as the canvas looks right to the end. Yogurt, but that's not good enough for her. She using this content. You don't know if we know a lot of information about this content in an old fashioned PDF.
What is a Unicode values for the text is actually in use him not really required very often. And in reality they in the reality is that funds having Coatings and doesn't odie's to be well defined and so the ability to get to a well-defined Unicode value is the important thing, you know, how you get that for the ability to say anything that you want to do with this. You have to know what the text is what it mean. I think it's brought Italian. What does it talk about language? What language is it in
town funny? If it's pronounced it was happening in my absence of all 50 Cent. Content into a smaller box - 8 problems without changing the meaning when you think about understanding. I'm just the obvious pronunciation. What's ambiguity until the rest of languages in the world but most western languages in the world PDF use cutting operations to bring test closer or further Park distinguish between a cow and a space-time PDF actually says a lot about doctor said this upfront a PDF
as a rule that each of these things to make people think about the fundamental rule for making contact machine accessible until my content if I can actually I got you into some type of brake without to do that. We fall again where to buy put my spaces wife for my hyphens because now I know how to float at contents into a about The only reason I know this is a heading is that as a human is that I infer that from sitting styling changes in this case is a
human how to refer to this is a headache again by Sublime confused assistive technology to walk through the headings of the doctor to Lomita navigate to it the ability to build a natural tables of the end-user provide. Navigation through the document to build on the speeches. He's very valuable and it does it means you don't have to isn't all that make all the decisions of friends as to what to put into the document before you take to go to publication. Again, I'm just pointing out here with a paragraph.
How do I differentiate between body text the paragraph versus that the different types of semantics directions to drain hair? Stepping back out in this case antique lace significance. Is it just a visual effect that I is a type of a freezer designer put in to make my document with will be nice to have some significance for it to know that if you're going to say refluff. Do I need to keep that background? Cuz I'm reusing that content. I texted each other to call document just a
touch her reading all that. I mean reading all this more fundamental than just call him to Colin. It's the flow of the paragraph is the flow of Inglewood PDF PDF does the basically these these documents have to have a order at the word level at the Block Level at the the the document level and so country. I can actually get this message out of the document which is really important to have to make that determination really want to get repeat the same as the content being able to identify those is really important.
Dismiss is missing my stuff. So basically we had about data the ability to inject data into the document has is really important in since I'm almost out of time out. Math data table data information that I can use when making good choices. Maybe I'm going to phone and instead of those are really important features that they train tables and namespaces the PD of 2.0 PDF 1.7. You only knew our taxes would they be put in that and then publish the thought of the ISIS stand it
if you would communicate that in a way that allows another of Cosenza opening to understand what it is Peter 2.0 excuses and take this to your apartment complex data into PDF. But the final take my I want to give is this a lot of mainstream music for data and semantics in PDF. Ended the movie unblocked sees the more we bring these into the mainstream. The more of you is actually maybe he's available to end uses the natural impetus. There is for the creative take me to the Best Buy benefits of it isn't a great
