We have read the journal’s policy and the authors of this manuscript have the following competing interests: Co-author, Kaylin White, MS, is a part-time consultant at MapHabit, Inc., the company that developed the assistive technology (the MapHabit System) that is used in this feasibility study. Ms. White receives compensation from MapHabit, Inc. Co-author, Samuel S. Han, B.A., is a part-time consultant at MapHabit, Inc., the company that developed the assistive technology (the MapHabit System) that is used in this feasibility study.

The recruitment of subjects participating in the study was done independently of the authors, and carried out initially by the LuMind IDSC Foundation, a national support entity for families with Down syndrome. Statistical analyses of all data were carried out independently of the authors by a biostatistical resource department of an academic health center. Other than sharing the costs necessary to carry out the study, neither MapHabit, Inc., nor any MapHabit Inc. employees have any financial link to the LuMind IDSC Foundation, or to the independent biostatistical resource used in the study. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
