Using the hand units instead of a flat keyboard for computer input has many
advantages. Here are some of them.
B e C om f or t a b le Wh il e W or k in g
To increase your working comfort you can:
♦
Reduce unnatural arm and elbow bends by tilting the hand units
and spreading them comfortably apart.
♦
Lean back in your chair while working by using the LapLander™
to place the hand units on your lap.
♦
Adjust the arch of your fingers, relative to your hand, by moving
the finger board up, down, forward or backward.
♦
Rest your hands on the palm supports. The supports come in
two sizes: large and small. They support your hands in a
relaxed position and eliminate wrist motions.
See the Ergonomic Suggestions section for more details and an
illustration.

To type on the hand units, you move the fingers only slightly in one
of 5 directions: north, south, east, west and straight down. You
move the thumbs in 4 directions: east, west, straight down and up.
This reduces the repetitive downward pecking motions of fingers
required to operate a flat keyboard and therefore reduces repetitive
stress exposure.
In c r e a s e You r Ef f ic ie n c y
You can easily touch-type all the keys on the hand units. Minuscule
finger movements access all the standard keys, the function keys
and the mouse, so blind reaches are eliminated. This reduces
finger workload and can also boost your productivity.
