Which method of mobility assistance utilizes air pressure to activate movement?

The method of mobility assistance that utilizes air pressure to activate movement is indeed the sip and puff system. This system works by allowing a user to control a device through inhaling or exhaling air from a straw-like apparatus. When the individual sips (inhales) or puffs (exhales) into the device, it generates air pressure that can activate switches or sensors, enabling movement or operation of various mobility aids, such as wheelchairs or other assistive technologies.

This technique is particularly beneficial for individuals with limited mobility or strength in their limbs, as it provides a way to navigate and operate devices using breath control. It exemplifies how adaptive technologies can enhance independence for those with disabilities, making it an essential consideration in the design of mobility assistance devices.
