Dexterity and
Strength Impairments:
Dexterity refers to the skill and grace in which a student makes movements,
especially with her hands. A person with dexterity or strength problems may have
trouble typing, lifting, moving, and/or holding a pointing device such as a
mouse. Though some individuals can hold the mouse, the majority of individuals
with dexterity problems cannot control it with enough accuracy to perform a
desired task.
If a user has a
dexterity problem, the instructional software must be compatible with voice
input devices or accessibility features within the personal operating system
such as "sticky key" options. Sticky-keys allow the user to press key
combinations sequentially rather than simultaneously. |
