Control Interfaces & Switches

Phyl specializes in supporting teams with learners that have significant physical challenges. Phyl guides the team in identifying the appropriate control interfaces or switch to access communication devices, allow access to computer technologies, and improve independence in accessing the environment.

In addition, Phyl assists teams with devising customized teaching lessons to use with these learners to teach step-by-step motor learning to develop appropriate access – an essential component when providing supports in this area.

Some examples of assistive technology supports in this area include:

	Mechanical Switches: These switches are activated by the application of force. Examples: Jelly Bean Switch, Leaf Switch, Paddle Switch, Wobble Switch, Plate Switch, Membrane Switch.
	Electromagnetic Switches: These switches are activated by the receipt of electromagnetic energy, such as radio waves or light. Examples: Infared switch, Sound Switch, Touch Switch.
	Proximity Switches: These switches are activated by a movement close to the detector in the switch, but without actual contact. Examples: Airtouch Switch, Untouchable Buddy.
	Pneumatic Switches: These switches are activated by the detection of respiratory airflow or air pressure. Examples: Sip-and-Puff Switches.
	Phonation Switches: These switches are activated by sound or speech. Examples: Voice-Activated Switch, Infared/Sound/Touch Switch.
	Switch Arrays: These switches can perform more than one action. Examples: Dual Rocker Switch, Slot Switch, Joystick.
	Chord Keyboards: These switches are an array of switches or keys with each one to be pushed by one finger.
