CONTROLERS
(figs 26 – 31)
7.1
There are 4 types of PRIMARY CONTROLLERS.
(a) 4-way joysticks - the basic system, the
simplest most reliable and easiest to use.
Can be operated by hand, chin or foot. (figs
26, 27, 28, 30 &31)
Fig 31 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 29), where severe
quadriplegia prohibits the use of a joystick.
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 better off
using a joystick.
(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 fin-
ger.
