Remember 2017? It feels like a different era in the world of technology, especially when we think about the tools that help people communicate. For those relying on Augmentative and Alternative Communication (AAC) apps, finding the right fit was, and still is, a deeply personal journey. Back then, the landscape was a bit less crowded but no less complex, with developers offering a range of features designed to bridge communication gaps.
Looking at a comparison chart from that year, like the one compiled by the University of South Carolina, offers a fascinating glimpse into the features that were considered crucial. We're talking about the nuts and bolts of AAC: how users could access the app (indirectly with a switch, or through audio scanning), the availability of keyguards, and options like 'activate on release.' These might sound technical, but they represent fundamental choices that impact daily usability for individuals with diverse needs.
Then there's the core of the app's design: how information is organized and presented. Category-based layouts versus grammatical-based layouts, the way messages and pages are displayed in a list view, or the presence of a sentence window – these all shape the user's experience. The ability to edit individual messages, hide symbols and text, or have core vocabulary readily available were significant considerations. And let's not forget the visual elements: the option to add photos, use a graphics library, or even create user-stored visual scenes that could link to other pages.
Text-to-Speech (TTS) was, of course, a major player. The distinction between synthesized speech (standard TTS) and digitized speech (user-recorded voice) was important, as was the ability to control voice output for messages, sentence windows, and individual symbols. The inclusion of a child's voice or a pronunciation editor could make a world of difference in personalization and clarity.
Beyond the basic communication functions, the chart highlighted features that added layers of sophistication. Text highlighting as text is read, phrase storage, word completion or prediction – these are the helpers that can speed up communication and reduce cognitive load. Handwriting options, spell check, and the ability to store core vocabulary words were also on the table. And for those who needed to connect beyond immediate conversation, email and social media options were starting to appear.
Editing capabilities also varied. Was editing accessed under settings, within the app itself, or did it require a computer? Could messages and icons be rearranged? The flexibility of a reconfigurable message square layout (2, 4, 8, 16, 32 squares) offered different levels of complexity and visual density.
While the specific apps listed in a 2017 chart might have evolved or been superseded, the underlying principles remain. The quest for intuitive design, robust features, and personalized communication solutions continues. Understanding the features that were available and valued back then helps us appreciate the progress made and the ongoing innovation in the AAC app world.
