The Accessible Platform Architectures (APA) WAI-Adapt Task Force (WAI-Adapt) invites implementation and welcomes comment on the Candidate Recommendation of the WAI-Adapt: Symbols Module. The purpose of this specification is to support Augmentative and Alternative Communication (AAC) symbols in web content. Millions of users comprehend AAC symbols better than standard text, but there are multiple AAC symbol sets and they are not mutually comprehensible. To solve this issue and make it possible for content creators to support AAC users in web content, this specification defines the appropriate use of Blissymbolics Communication International (BCI) concept indexing as specified by the W3C Alternative and Augmented Communication (AAC) Symbol Registry in web content, provided guidance on associating an appropriate BCI index value with a span of text corresponding to the defined concept expressed as standard text, and it is anticipated that user agents will display the corresponding AAC symbol from the user’s preferred symbol set by allowing the user to configure for their preferred AAC symbol set and cache that symbol set locally. Please send comments by 28 February 2023.
