Currently Weave is not able comply to a WCAG level of accessibility as it is a mapping application and some level of vision is required to view the site. If Weave is configured to provide a text only interface (Grid Based) then compliance can be achieved.
Weave also provides comprehensive tooltips on many parts of the interface allowing users to get or find functions easily. The tooltips are configurable and allow a site to change the content of the tooltips to suit the needs of that site. Weave also provides keyboard shortcuts such as the ability to navigate around the map using the arrow keys and the plus and minus keys to zoom in and out for example.
