Controllers (figs 31 – 36)
There are 4 types of PRIMARY CONTROLLERS.
a.
4-way joysticks - the basic system, the sim-
plest most reliable and easiest to use. Can be
operated by hand, chin or foot. (figs 31, 32,
33, 34 & 35)
Fig 36 is a computer game type joystick
adapted with our 9 way connector as an ex-
ample of what can be used
b.
Sip and puff - (fig 32), where severe quadri-
plegia prohibits the use of a joy- stick. Each sailor
requires a personal module to guard against spread
of infection. This is an unnecessary added expense
which can be avoided for most sailors who are bet-
ter off using a joy- stick.
c.
Paddle switches - great for people with severe
CP and the like who have difficulty with fine finger
movements and insufficient control of their breath
for sip and puff.
d.
Push Button – 4 closely nested push buttons that can be operated under a thumb or finger.
