The information from the CD, Boardmaker Plus activity and reading Carolyn's Blog got me thinking about the importance of a switch or switches for a person's life to become more independent. Questions from class:
What is a switch? " A switch is a mechanical device that closes an electrical circuit to turn object on and off."
Who uses switches and why? Anyone that is not able to complete the specific task independently could use a switch.
Criteria for selecting a successful switch.
- Position of the user to access switch
- Movement Pattern- Is there a voluntary part of the body that can move or not helps determine type pf switch
Control site - what part of the body (i.e arm, knee) or action (i.e breath, blink, motion or infrared rays) will make the switch work
Types of switches - Simple or speciality.
I wonder how many people in the world should have switches and either don't know about them or don't have access to them? How tells those that need them, they are available?
