Enabling people with intellectual and other disabilities to make verbal requests using cardboard chips with mini objects or pictures and a smartphone.

Only six participants with intellectual, sensory and motor disabilities were studied, so the result does not show the system works for other people with intellectual, sensory or motor disabilities. The participants received a tailored package of chips, RFID tags, a smartphone app, selected activities and staff responses; the study did not separate the contribution of any single component. The study did not assess whether participants liked or understood the system, because they could not sign consent and no satisfaction measure was used. No maintenance or generalization data were reported, so it is unknown whether requests continued without the study setup or transferred to other staff, settings or times. The staff survey was based on a 3-minute video and staff had no connection with the participants, so it does not show day-to-day feasibility. The design was a non-concurrent multiple baseline, and the authors noted it is weaker than a withdrawal design.

Do not conclude that the smartphone alone caused the requests. The participants used a tailored package of cardboard chips, RFID tags, an app and staff responses, and the study did not test maintenance or generalization.
