Being able to visually navigate pages and get sound feedback as you move seems valuable. This is a bit different to what most visually impaired people do which is navigate by sound and structure alone. So as Jonathan says, it implies different requirements. It seems that SVG or XHTML, and a bit of SMIL, are a likely way to solve this easily, although it isn't a trivial problem. It could of course be done more or less just in SMIL for visual presentation, but it would seem a bit artificial. (You define layout regions for each image or letter in peepo, and then you use interaction events to play a sound - less ideal than the integrated approach). The SVG 1.2 working draft says The SVG Working Group may produce a W3C Note which defines an SVG+SMIL profile, similar to the XHTML+SMIL profile [XHTML+SMIL]. Alternatively, SVG could include more of the SMIL elements within the SVG namespace (e.g. the par, seq, audio and video elements). -- http://www.w3.org/TR/SVG12/#xml-integration There are demos of doing this that I have seen, although I couldn't find one in 15 minutes of looking. Maybe X-smiles has one... cheers Chaals On Thu, 5 Dec 2002, Jonathan Chetwynd wrote: > >unfortunately onclick does not suit our users, ie how do you click a >link which has an associated sound, by onmouseover, having to learn to >click a separate symbol takes up huge amounts of screen, visit peepo >and imagine where would the extra symbols fit, we are advised that 80 >pixels is a minimum size for a graphic. > >jonathan >On Wednesday, December 4, 2002, at 02:11 PM, David Poehlman wrote: > >> on click perhaps? >> >> ----- Original Message ----- >> From: "Jonathan Chetwynd" <j.chetwynd@btinternet.com> >> To: <w3c-wai-ig@w3.org> >> Sent: Wednesday, December 04, 2002 8:21 AM >> Subject: sound on event: a possible way? >> >> >> >> http://www.peepo.com/w3/sound-on-event/test.html >> >> could those following this thread please comment on this method*? >> >> thanks >> >> Jonathan >> >> >> *active ingredient: >> link.innerHTML= '<object><embed src="' + thisSound + '.wav" width="0.1" >> height="0.1" /></object>' >> this surprisingly updates itself, allowing sound on event >> > -- Charles McCathieNevile http://www.w3.org/People/Charles tel: +61 409 134 136 SWAD-E http://www.w3.org/2001/sw/Europe ------------ WAI http://www.w3.org/WAI 21 Mitchell street, FOOTSCRAY Vic 3011, Australia fax(fr): +33 4 92 38 78 22 W3C, 2004 Route des Lucioles, 06902 Sophia Antipolis Cedex, France
