<p>Products for people who are non-verbal often use symbols to help users communicate. These symbols are in fact peoples' language. Unfortunately many of these symbols are both subject to copyright AND are not interoperable. That means end-users can only use one device, and cannot use apps or content from a different company. If we enabled mapping to open sets of symbol codes that, in turn, map to open or proprietary symbol sets, then they can be interoperable. At the user end, the user agent can load the symbols that the user knows. Symbol sets might still be proprietary but they would also be interoperable. That means the end user could use them across different devices, or any compatible content or applications. This is addressed further in the issue paper on symbols for people who are non-verbal.p>
