Just in time! Out today in Smashing Magazine: a wonderful and very readable article describing how and why accessibility APIs work.

"Microsoft Active Accessibility" (MSAA) is Window's application programming interface (or API) for communicating accessibility information. AutoCAD is apparently saying that they pass object, name, and state information to the API that can then be used by assistive technologies. If it doesn't work with JAWS, however, they are probably not sending enough of the right information, or that they have actions that can't be completed by keyboard alone - if you can't get to an object, it can't send information about it and you can't operate it.
By the way, Microsoft is replacing MSAA with Microsoft UI Automation. (This is a (fairly technical) comparison article from Microsoft: https://msdn.microsoft.com/en-us/library/ms788733.aspx<https://urldefense.proofpoint.com/v2/url?u=https-3A__msdn.microsoft.com_en-2Dus_library_ms788733.aspx&d=DwMFAg&c=lDF7oMaPKXpkYvev9V-fVahWL0QWnGCCAfCDz1Bns_w&r=rhLenV33VPpmkT7iP0-OkUlRYw9YWn3HMLHZVP2q9y8&m=dEQJDxW4WqUBXH1z0iSRgA4Q5DQ9FM_GNdoCNwauqXw&s=1DXROGmSPfYKECJOPlRtMkRfS00IWnzdKK86PgphUgM&e=>) I'm not sure that AutoCAD should be proud that they're still using the older and more limited MSAA.
