Table 6.

Summary of features that support person-centered communication (PCC) in the evaluated communication apps (cApps; this table describes PCC features found in the evaluated cApps during the 2015 review and in the 2017 replication review, as well as evaluates the percentage of cApps with a PCC feature between the 2015 and 2017 reviews. Data were extracted from the Canadian App Store description and during the prepurchase review of the cApps. Feature categories were not mutually exclusive; therefore, 1 app could have several built-in features and/or custom features).

aAAC: augmentative and alternative communication.

bPercent change calculation: ([percentage of 2017 apps with the feature−percentage of 2015 apps with the feature]/percent of 2015 apps with the feature)*100. A negative percentage indicates a decrease in the percentage of cApps with the person-centered communication feature over the 2-year period.

cFeatures that support vision loss include high-resolution images, zoom function, and large pictures/text.

dFeatures that support hearing loss include volume control, earbud option, speech rate adjustment, voice customizations, and speech-to-text function.
