Add Accessibility Considerations to Use Cases

[mmccool]

As discussed in APA/WoT Joint call Oct 14, 2020

• Added accessibility (and internationalization) considerations to template

• Smart Buildings

  • ISO standard for smart door locks (also credentials; TODO)

• Professional users

  • Eg disabled farmers in Ag use case

• Automotive

  • Disabled drivers or passengers

• Transportation

  • When is the next bus?
  • When is my stop
  • Where is my taxi?

• Logistics

  • Package delivery - where should it go?
  • Lockbox - package is available, notification

• Existing accessibility use cases

• NEW Use cases

  • Publishing, including recipes

• Overlap with internationalization

  • Text direction
  • Personalization for people using symbol sets rather than speech (but... multiple systems...); APA task force

• Discovery

  • Eg find accessible doors, trigger lifts, etc.

Overarching:

• User interfaces will almost always raise accessibility issues

  • relatively well understood, especially if can map onto web browser platforms

• Vertical integration needs, e.g. for an API

  • ex: second screen synchronization tolerances e.g. for lip reading
  • middleware (devices are accessible, but middleware might not be...) See:

• https://www.iso.org/standard/60821.html - ISO/IEC 24752-1:2014 Information technology — User interfaces — Universal remote console — Part 1: General framework - relates also to "semantic annotation" for UIs used by IoT devices

• Semantics

  • Possibility to infer UI requirements from higher-level semantics, may not need explicit "modality" annotation in all cases (but would still be nice)

Regarding personalization for people using symbol sets, please see the video from the personalization task force of the APA: https://www.w3.org/2020/10/TPAC/apa-personalization.html

Let's aim to update the use cases, discussing things in this issue, then aim to meet and review again later this year, perhaps in December. This time works, so... Dec 9 at 9am Eastern.
