RE: Points of Information and Clarification Regarding House Subcommittee Hearing on Internet and ADA
First I would like to thank the Chair for the opportunity to add comments to the record of the House subcommittee hearing on the Internet and the ADA.
I spoke with you after the hearing last week, providing information on some of the topics and questions raised during the hearing. As per our discussion, I am sending this follow-up note so that the information can be included in the formal record of the hearing. These notes simply repeat or elaborate on the topics we discussed after the hearing.
For your records I am Gregg C. Vanderheiden, Ph.D., Professor in the Industrial Engineering Department, and Director of the Trace Research & Development Center at the University of Wisconsin-Madison. I am the principal investigator for the Rehabilitation Engineering Research Center on Information Technology Access, funded by the National Institute on Disability and Rehabilitation Research, U.S. Department of Education. I also work with the Partners for Advanced Computational Infrastructure (PACI) Program funded by the National Science Foundation.
The Trace R&D Center focuses on ways to make standard information technology and telecommunication systems more accessible for people with all types of disabilities. Trace works closely with the W3C's Web Accessibility Initiative and I co-chair and co-edit the W3C-WAI Web Content Accessibility Guidelines. I was also a member of the Electronic and Information Technology Access Advisory Council (EITAAC) of the US Access Board.
Another area of inquiry at the hearing that was not clearly covered was whether the Web Accessibility Guidelines allow the use of graphics, or discourage their use. The answer is that graphics, icons or color are not barriers to accessibility. In fact, the Web Accessibility Guidelines encourage the use of graphics. They make the Web easier for many individuals with different types of disabilities (as well as other users). The guidelines do say, however, that where information is presented ONLY in graphic form, that the information should also be available in text form and that information that is conveyed with color should also be available in another way.
It should be noted that this alternative text (which has been required for the past 2 years as part of standard HTML) is usually invisible to a reader who has graphics turned on. Thus the use of alternative text would not alter the appearance of the Web page at all. The text only appears when the graphics are turned off (or before the graphics are loaded). Incidentally, the text is also visible to search engines, which makes the pages easier to find using search engines. It is also useful to anyone using phone browsers, or with slow Internet connections.
During the hearing clarification was sought (but not received) on whether the Web accessibility guidelines require Web sites to provide at least one mode of presentation that minimizes the cognitive and memory ability required of users.
The answer is no. This requirement is not part of the W3C Web Content Accessibility Guidelines or requirements proposed by EITAAC for the Web content. Rather, the statement referred to above is from the EITAAC general guidelines that apply to all electronic and information technology. That clause is meant to cover a wide range of products, from copiers to phones. The clause from the EITAAC report that addresses Web accessibility (and would be used to interpret any general guidelines) was located lower in the report and specifies the use of Priority 1 and 2 guidelines (only)of the W3C-WAI Web Content Accessibility Guidelines.
The appropriate EITAAC report item for Web access is:
18.104.22.168 Web content shall conform with level 'Double-A', satisfying all Priority 1 and 2 checkpoints, of the World Wide Web Consortium (W3C) 'Web Content Accessibility Guidelines 1.0' available at http://www.w3.org/TR//WAI-WEBCONTENT
The language in the Web Content Accessibility Guidelines that applies to this is:
14. Ensure that documents are clear and simple so they may be more easily understood. 14.1 Use the clearest and simplest language appropriate for a site's content. [Priority 1]
(There are also two Priority 3 guidelines in the W3C guidelines for this area. However the EITAAC did not include any Priority 3 items in its recommendations so they would not be included.: - 14.2 Supplement text with graphic or auditory presentations where they will facilitate comprehension of the page. [Priority 3] and - 14.3 Create a style of presentation that is consistent across pages. [Priority 3] ")
Clarification was sought during the hearings as to whether Web accessibility requires a "One-size-fits-all" or " least-common-denominator" approach (i.e. whether Web accessibility mandates a single presentation format or mandates a format that is very simple and basic).
Neither of these approaches is required or recommended by the guidelines. In fact the guidelines specifically caution against that approach. Instead the guidelines recommend that pages be created in rich but flexible ways that allows users with different constraints to be able to view and use the content. (This includes both those who have a disability and those that are just using mobile technologies like phones to access the Web).
A common misunderstanding is that accessibility regulations restrict the way information on the Web is presented. There are no guidelines or regulations that outlaw a particular form or technology from be used to present information on the Web. The closest thing that will be found is a recommendation that W3C technologies or other technologies developed in an open fashion be used. However, this is not a requirement, and the guidelines simply state that if other non-accessible technologies are used, that the information be available in some accessible fashion as well.
11. Use W3C technologies (according to specification) and follow accessibility guidelines. Where it is not possible to use a W3C technology, or doing so results in material that does not transform gracefully, provide an alternative version of the content that is accessible.
In most cases, the alternate accessible form is a short text phrase that only appears if requested.
During the hearing, a concern was raised regarding whether companies would be forced to tear down their Web sites or carry out extreme or burdensome conversions.
First - it should be noted that the vast majority of all information and services on the Web can be made accessible for something on the order of 00.01% to 01% of the cost of creating and providing the information or service in the first place - especially if accessibility is addressed from the beginning of development. This would be far below any likely determination of an "undue burden" threshold.
For those situations where excessive effort is required for some reason or portion of the site the "undue burden" clause of the ADA would come into effect.
Again - it should be noted that in almost all cases, making Web sites and services accessible to people with disabilities also makes them more useable to people (without disabilities) who use small pocket computers, PDAs, cell phone browsers, and other mobile browsing technologies.
The suggestion was made during the hearing that 'hundreds of millions of existing pages would be torn down' from the Web if there were requirements for Web accessibility.
The Web relies on URL's being "persistent," in other words, having stable addresses. W3C Recommendations emphasize building a stable Web for today and for the future; no W3C Recommendation has ever suggested removing pages from the Web, for accessibility or for any other reason. To do so would create a far worse accessibility problem for Web users, including people with disabilities, since people would encounter "dead links"-no information at all-when trying to access pages that had been removed.
If a site to which the ADA applied could not be made accessible with a reasonable amount of effort, the undue burden provisions of the ADA would apply, and no site would need to be removed. Therefore this scenario is not a logical consequence of requirements for Web accessibility. It is not what is being sought by the disability community and removal of pages if there was not an undue burden to make them accessible does not make economic sense.
During the hearing the assertion was made that the Internet was not a public accommodation because the examples listed in Title III were all physical places.
It should be noted that the examples do not anywhere specifically say that they must be physical places. The actual terms used were "place" or "establishment". In addition, of the 12 examples listed in Title III all but 3 of them are activities that are being carried out on the Web today. The 3 that are not on the Web all require the physical presence of one's body. They are
(1) an inn, hotel, motel; or other place of lodging, . . .
(2) a restaurant, bar or other establishment serving food or drink;
(7) a terminal, depots or other station used for specified public transportation;
Four of the 12 deal with entertainment and exhibition
(3) a motion picture house, theater, concert hall, stadium or other place of exhibition or entertainment;
(8) a museum, library, gallery or other place of public display or collection;
(9) a park, zoo, amusement park or other place of recreation;
(12) a gymnasium, health spa, bowling alley, golf course or other place of exercise or recreation.
The Internet is (or soon will be) a location of entertainment that is used more than all of the listed examples in this area combined. It is used for viewing movies, concerts (live and recorded), watching games (live and recorded) and exhibiting things of all types --- including collections from museums and art galleries that are not otherwise viewable by the public. There are libraries and entertainment sites of all types. Many more and of much greater variety than are available in any but one or two cities in the US. The only items in this list that are not available on the Internet again are those things that require physical body presence. And even here, virtual reality sites are beginning to break new ground
The remaining examples cited are also all commonly available on the Web:
(4) an auditorium, convention center, lecture hall or other place of public gathering;
The Internet has created a whole new categories of gathering places including chat rooms, joint video meetings, distance education classrooms, remote lecture halls and more
(5) a bakery, grocery store, clothing store, hardware store, shopping center or other sales or rental establishment;
Sales of goods and services via the Internet is well established and rising quickly. In many cases goods are available via the net that cannot be obtained otherwise in local communities or via any catalog that a person would have (or in many cases - that they would qualify to receive in the mail). In addition, an increasing number of sales establishments exist only on the Internet making access or use via any other means impossible. Thus the Internet not only an example of sales and rental establishments - but it is an example of unique sales (and rental?) establishments that are not otherwise available locally or at all.
(6) a laundromat, dry cleaner, bank, barber shop, beauty shop, travel service, shoe repair service, funeral parlor, gas station, office of an accountant or lawyer, pharmacy, insurance office, professional office of a health care provider, hospital, or other service establishment;
Although not all of the service establishments listed here are available on the Internet, all those that do not require physical presence are. Travel services on the Internet are so good and cost effective for consumers that they threaten local travel agencies. They are also available at hours that local agencies are not. Accountants, lawyers, insurance and even medical advice and care are available via the Internet. Again, for many localities, there is no other local equivalent to what is available to a person via the Web.
(10) a nursery, elementary, secondary, undergraduate or postgraduate private school, or other place of education;
The Internet is certainly a place of education. Both formal, and informal education is conducted via the Web. And use of the Web is rapidly becoming a requirement for any high or secondary school education.
(11) a day care center, senior citizen center, homeless shelter, food bank, adoption agency or other social service center establishment;
Social services are increasingly being offered via the Web. Again, it may be the only way for people in outlying communities to access social service information and services.
The question was raised as to whether regulation was needed - or whether industry was already working on access.
A couple of observations can help to shed some light on this question. First - it should be remembered, that all of the companies working on more accessible Web technologies, Web sites, etc., in any serious and concerted fashion are aware of the ADA, and most are aware of the Justice Department's ruling. Thus there is already a regulatory motivation in effect. Further, it is known that many of these companies would reduce their efforts significantly if there were no mandates and they knew that there would be no future mandates for the accessibility of their material.
An interesting parallel to this was observed with Section 508 the first time it came out. Section 508 required that computers and information technology purchased by the government be accessible to people with disabilities. A number of companies began gearing up accessibility efforts. Employees within companies told their management about the regulations and the fact they should be creating more accessible products to better compete for government contracts. Later, when the initial 508 was only sporadically enforced and companies were not seeing accessibility provisions showing up in government RFPs, I began receiving calls from company employees saying that their companies were scaling back accessibility efforts as a result of the lax enforcement of the regulations.
I have heard similar rumblings with regard to Internet companies' behavior if the Internet were suddenly to be declared an accessibility-regulation-free environment.
Several presenters suggested that economic motivations might cause industry to make their technologies accessible even without any regulation. The Trace Center has done extensive work with industry (including building access features into standard products) and has not found this to be the case. Trace has also just completed a three-year study looking at why companies do or do not incorporate accessibility features into their main product line. This research also supports the position that companies will not engage in substantive, long term accessibility efforts across their main mass-market products in the absence of either regulation or the fear of regulation.
Although other (non-regulatory) motivations have led to particular actions or caused features to appear, these efforts have not been maintained or applied across product lines. Companies also often provide particular access features for a product but omit other key access features resulting in a product that is only partially useful or useful only for people with some disabilities. Unfortunately, the piece that they do not provide access to is sometimes the "front door". In the context of the Web this appears as Web site that is largely accessible except that a person cannot use any of it because a few pages at the front are impassible.
Even when access is easy to implement it is very hard to accomplish in the absence of a strong motivator. Everyone in these companies is so busy that they are only getting to those things that are absolute financial homeruns or absolute necessities. Side markets, additional markets, diverse markets (such as people with disabilities) often end up on the list of "important things to do" that people never get to.
This is best illustrated by a story once told to me by a vice president of a large technology corporation.
It started when he asked me, "Why don't you just pass a law that requires us to do this." After asking him to repeat what he said, I told him how surprised we were to hear him say that and asked him why he said it. He said, "Two reasons".
"First," he said, "I think this is a really important thing for us to be doing. I only wish that I could present it to my colleagues as well as you did. Be that as it may, I'm going to take these materials back, and I'm going to set it right on top of my desk as a very important thing to do. However, also on my desk will be about six other stacks. Furthermore, two of them are likely to be smoking, and one of them is going to be on fire. I'll start putting out the fire, and one of the smoking stacks will burst into flame and another one will start smoking. I will spend the rest of today putting out the fires and hopefully a couple smokers. When I go home tonight, I'm likely to still have a couple smokers. And in the morning my secretary will bring in four more stacks - at least one of which will be on fire and one of which will be smoking. This is the way the rest of the week, the month, and the year will go. A year from now, your materials will still be sitting on the corner of my desk. It will still be just as important -- and I'll still be putting out fires. It's just the way my job works.
"But if you pass a law that says our company must do this, then your stack will start to smoke...." (he paused for effect)
"Also, if you pass a law, you solve another problem for us. Things are so competitive in our industry that we are afraid to ever take time out to work on anything that we don't know that our competitors are also looking at (unless it will let us leapfrog them in the market). If you pass a law that says we all have to do this, then we don't need to be afraid to take time out to address these issues - even if it is small."
That company was a not an Internet company but his analysis sounds to be even more true in the area of Internet.
Disclosure Statement: "I am a Professor at the University of Wisconsin and direct a research and development center with funding from the US Department of Education, National Institute on Disability and Rehabilitation Research, the US National Science Foundation, and industry. Last year I was asked by the National Federation of the Blind if I would consult with them in their complaint against America On-Line. I agreed to consult, and I have had one phone call with NFB staff on this matter back in November 1999 and none since. At the time I told them that I would also be available to answer questions for AOL should they ask. Also, I had asked that any fees that might be involved be donated directly to charity - so I have no financial interest in that case.
