In 2011, Ennis-Cole & Smith conducted a case-control study in which a large sample size of 85 participants was recruited between the ages of 10 to 17. The outcomes were positive across all studies as they successfully increased a variety of skills of communication which also increased other skills such as joint attention, self-help, task completion, motivation, and appropriate behavior (Ennis-Cole et al., 2011). Sampath, Agarwal, & Indurkhya conducted a case-control study in 2013, using AutVisComm, an assistive communication system. This assistive communication system was developed in close collaboration with not only teachers but with the parents of children with autism. The study included 24 children with autism (CWA) all of which were 8 years old. The goal of the use of this AT was to help the child learn to request his or her desired object using the application AutVisComm. Each child had two one-on-one sessions per week with a teacher, in which a food item was placed out of reach of the child and close to the teacher.

Finally, if the child still did not respond after a VP the teacher would physically assist the child (Sampath et al., 2013). During the initial
