'touch-based' originates from the combination of 'touch' and 'base,' where 'touch' refers to the sense of physical contact and 'base' implies a foundational or primary aspect.

'Touch' and 'base' have been used in English for centuries, with 'touch' deriving from Old French 'touchier' and 'base' from Latin 'basis.'

Initially, 'touch' referred to physical contact, and 'base' meant foundation. Together, they evolved to describe technology that relies on touch.
