An assistive technology device is defined as:
“any item, piece of equipment, or product system, whether acquired commercially, modified, or customized, that is used to increase, maintain, or improve functional capabilities of individuals with disabilities.”

A tandem bicycle, for an autistic child that has problems with his motor skills.  The child and a parent may both paddle, stop and steer, but the child steering will take effect only after the parent approves the child intention. 

A Need-Knower with a hand tremor is looking for an assistive device that will minimize the tremor impact on everyday activities involving the use of the hand.

Help us provide an adaptive and modular assistive solution that will help make the effective lifting, holding, and moving items more stable for that person.

Our Need-Knower needs, due to a disability, an XBOX and PS  game controller designed to be used only by the right hand. 

In order to address the single-handed controllers at large, the design should allow (  although not necessarily in the same instance)  to operate as a left only single-handed controller as well.
