What does the term "sip-and-puff switches" refer to in assistive technology?

The term "sip-and-puff switches" refers to a system for hands-free interaction in assistive technology. These devices are designed to help individuals with limited mobility control various electronic devices, including computers, wheelchairs, and other assistive devices, by using their breath. The user can sip (inhale) or puff (exhale) into a straw-like apparatus, which sends signals to the connected device. This allows individuals who are unable to use their hands to interact effectively and maintain independence.

The functionality of sip-and-puff switches makes them particularly valuable in creating accessibility for those with severe physical disabilities. They provide an alternative means of communication and control, emphasizing inclusivity within technology. Other options, such as visual aids, complex keyboard designs, and traditional mouse control, do not embody the unique hands-free capability that sip-and-puff switches offer, making them less relevant in the context of assistive technology focused on enabling individuals without the use of hands.
