Re: Draft talk Maps for the Web Workshop

Great start Nicoló. I wonder how we can tie your demonstrations and the 
thrust of the paper into the higher level theme of the need for Map 
related semantics in HTML? Could these examples be offered as - a 'here 
is what we can do now with JavaScript and polyfills etc but if we add a 
Map element or upgrade current existing HTML elements it would be better.'?

Just some thoughts about how to bring in some current RQTF/APA concerns 
into the presentation. Thoughts? Jason and Janina?

Thanks

> One of them is about the need for annotations of geolocated data and

> Maps can be either complex or simple, can show a lot of information or 
> few. According to the user needs, maps are often configurable and 
> users switch to different views for the same data.

> Several accessibility related use-cases will be showed with 
> requirements to solve them. Some examples:
> - a wheelchair user wants to know about wheelchair paths on the 
> current map
> - a pedestrian needs to know a path available to reach a specific 
> place safely by feet
> A possible solution to the needs above can be to provide a contextual 
> menu to switch between different views of the same map/area.
> - a blind user needs to hear about the current map size, the 
> boundaries and possibly move the map to highlight a different area
> The boundaries of the map can be read aloud by the Speech Synthesis 
> tool as those information are provided on the screen as text, as well 
> as the extension of the map currently showed
> on the screen. Four HTML buttons can be provided to move the map and 
> change the zoom level to navigate the area, and look for new data.
> - users should be able to change the map unit according to their needs 
> (meters, kilometres, foots, miles, etc.)
> People from different countries are comfortable with specific units 
> and can found problems in reading the map with different units.
> - A blind user wants to navigate the map without feeling frustrated 
> and loose too much time in moving the selected area.
> Map scale is fundamental to have an idea about the extension of the 
> area currently shown on the map. Scale (that can be unified with the 
> idea of ‘zoom’ level) should be available as a text annotation.
> More example will be highlighted during the talk.

> I will be available for modifies until Monday 27 then I will be away
