However, it is unclear to what degree these opportunities have been realized in practice. We conducted a field study to explore the use of one such application, TalkingTiles, by individuals with aphasia. Following a training session and one week of use, we conducted interviews with participants, their partners, and their caregivers at a local support facility. We found that TalkingTiles can be effective in supporting communication when used in concert with other communication methods, and when time can be invested in customizing the app. We discuss our findings, and implications for design with respect to customizability, simplicity, and the limitations of interactive surfaces in supporting communication.enaugmentative and alternative communicationaphasiaConference Paper
