(1) Formulate extensive mapping of physical conditions in farmers to congenital disabilities of CP patients;
(2) Design low-cost, mass customized, highly usable AT prototypes for assisting farmers in extreme environments and reducing ergonomic risk exposure during planting tasks based on available ATs for congenital disabled CP persons;
(3) Preliminarily conduct empirical evaluation of ATs using high-fidelity lab mock-ups of work tasks; and
(4) Provide dual-use potential of the design interventions for assisting farmers in extreme environments and reducing ergonomic risk exposure, as well as supporting and improving CP patients daily living tasks.
