The Human Activity Assistive Technology (HAAT) model is a widely used theoretical framework for the provision of assistive technology (AT) (Giesbrecht, 2013). The purpose of this model is to help prescribe a solution for individuals with disabilities by using an assistive technology system. The HAAT model helps guide assessment, prescription, and evaluation (Giesbrecht, 2013). Using this framework to guide Juan's assessment, prescription, and evaluation process will be beneficial and will further allow therapists to predict successful outcomes for Juan.
