Description
Summary:We describe a smartphone/smartwatch system to evaluate anomia in individuals with aphasia by using audio-recording-based ecological momentary assessments. The system delivers object-naming assessments to a participant's smartwatch, whereby a prompt signals the availability of images of these objects on the watch screen. Participants attempt to speak the names of the images that appear on the watch display out loud and into the watch as they go about their lives. We conducted a three-week feasibility study with six participants with mild to moderate aphasia. Participants were assigned to either a nine-item (four prompts per day with nine images) or single-item (36 prompts per day with one image each) ecological momentary assessment protocol. Compliance in recording an audio response to a prompt was approximately 80% for both protocols. Qualitative analysis of the participants' interviews suggests that the participants felt capable of completing the protocol, but opinions about using a smartwatch were mixed. We review participant feedback and highlight the importance of considering a population's specific cognitive or motor impairments when designing technology and training protocols.
