Creating User Interfaces Another example. Classwork/homework: work on VoiceXML project
HTML5 and Accessibility • http://www.w3.org/Talks/2014/0317-HTML5-A11Y/?utm_source=html5weekly&utm_medium=email • My source for this was a newsletter: HTML5 Weekly: http://html5weekly.com/issues/131
Proposal • Due today • Level [at least] of rock, paper, scissors or family greeting • Can use a built-in grammar • Consider use of JavaScript
Caller id and question • http://faculty.purchase.edu/jeanine.meyer/tellme/callerIDmajor.xml • Uses session.callerID • Groups of answers • The nomatch condition handled differently from noinput
Examine code • Uses say-as element • What do you think it does without this? • Older example split up number into digits • Group choices of area of interest that have common value • one-of • tag
Possible Improvements • Improve on say as telephone by breaking up number and saying area code. • Use an external grammar. • ?
Production system • Capture name in some way • Invoke server-side code to store phone number (called ID) and name and area of interest • Transfer to another number
Mixed initiative • The VoiceXML feature for handling utterance with more than one result • Example given in tutorial: celebrity and location.http://help.voxeo.com/go/help/xml.vxml.tutorials.mixed • Example given in Microsoft tutorial: City and State • Note: can be more than two things. • Elements: <initial>, <field> and <filled> but in different arrangement, <catch>
Suggestion for mastering mixed initiative • Study example(s) • Download and upload to your account the dead celebrity location files. Test. • Change list of people and locations. Test. • Change subject: prompts AND list of people, locations, filler text. • Add a third field.
Voxeo • It is free! • Documentation and many examples are there. • Problem: website has old documentation (need to support legacy users). Make sure you are looking at most up-to-date examples. • Look at: http://help.voxeo.com/go/help/xml.vxml.bestprac.vui • More?
Classwork/homework • [proposal] • Work on project • Always look at file source • Confirm latest • Checks [some] errors • Legal XML may not be legal VoiceXML. Check in the documentation what are valid parent and child elements. • If system reports internal error, try again. May be timing problem • Do repeat testing!
