AAC symbols need to be bespoke, personalised and relevant to the time of communication as well as the setting and task being undertaken. However, this is not always possible in the time available with on the spot conversations. Where there is time to adapt symbols the process often has to be carried out in special programs. To over come the need to search out these special programs or apps Tom Lam has developed a very simple online application that allows those looking for symbols on our web site or from any other site to add elements to the original symbol. Changing the usage of a symbol to fit the needs of a particular language (Lundalv et al, 2006) is also important and may require arrows going in different ways such as from left to right to denote past in Arabic but future in English.
We provided examples of how this could be done in a previous blog and now you can experiment and develop your own symbols using the ‘Symbol Creator’ on the Tawasol symbols website. It is possible to add borders, background colours, text labels, arrows , plus or minus symbols that can provide plurals or signs for more or less. Other symbols can be added on top of the first symbol in miniature to offer gender differences etc but as this is on the web it is not possible to change the order that you add things so the first item will go to the back and so on. But you can delete any of the symbols when you highlight them and re-upload to get the order right! We are looking into how we can make this process easier.
Resizing is possible but the canvas has been set to 500×500 pixels to fit with the original size of all the Tawasol symbols. However, you can save the results in several formats and carry out any other adaptations in other graphical packages. Because the Symbol Creator is online it is important to save the final version as a download as soon as possible! This process will wipe what has been done but you can always upload the image again.
Although the tool will not offer all that can be achieved with a sophisticated commercial program, it will provide an instant method of adapting symbols. There are other online options such as those offered by ARASAAC for symbol creation and phrase making.
Of course, this is only the beginning of a process as Amy Speech and Language Inc demonstrate in their examples of communication boards or stories for symbol users and Lessonpix has a sharing page that provides more resources.
The exciting bit is when one can generate text to symbol sentences that make sense or symbol to text sentences that allow both the symbol user and their friends and family communicate more easily across the airwaves! Have fun with the Text2Picto beta online text to symbol processor. (Sevens et al 2015) to learn more about the issues of sentence generation.
