Assistive Technology Continuum and its Significance

  There are no hard and fast rules for assistive technology, rather the devices must be individually keyed towards the needs of each student.  There are three general levels on the continuum.  The first are low-tech adaptations for using a computer.  They include keyboard labels (for students with visual or attention issues) pointing devices (for students with physical disabilities),  keyguards  (for students who need help targeting keys) and  moisture guards (for those who spill or drool) and magnifying lenses.  Many students needs can be met with these lower technology devices.

Further along on the continuum are mid-level and high tech level  AT devices.  Some of the devices are trackballs,  joysticks, touch screens, head-pointing systems and eye-gaze;  each provides an alternate means of using a mouse.

 

Typically these devices are more for students with fine or gross motor control issues.  While I may not encounter many students with these greater needs; I undoubtedly will come across some and this awareness will better help me meet the individual's needs.
