The Assistive Technology Continuum

Students are different and this is evident when trying to decide which technology is right for that specific student.  The assistive technology continuum is the full range of technology from low tech to high tech.  Low-tech is where the consideration for assistive technology should start and progress to medium-tech and finally to high-tech solutions.  Students must be treated individually as there are no hard and fast rules to determining which technology fits with a specific student.

There are major types of alternative keyboards and characterisitics of students who would benefit from such keyboards.  Here is a chart that explains the adaption, type, and student characterisitc that would benefit most.

Low Tech Adaption:                  Type:                      Student characteristics:

Keyboard Label                     Larger letter                    Have visual/perceptual issues/low vision
                                               High contrast colors       Have low vision
                                               Braile                              Blind/Braile Reader
                                                 
                                               Blank        Have cognitive deficits/visual perceptual/attention issues 


Selecting/Pointing Devices      Handheld dowel              Unable to isolate a finger
                                                  Mouthsticks                    Good head control
                                                  Chinsticks/Headsticks

Keyguards                                  Acrylic or metal             Need targeting assistance
                                                                                          Use selecting/pointing device
                                                                                          Need wrist support

Moisture Guards                         Transparent                   Tendency to spill/drool
                                                    Printed with key labels  Have low vision

  1. I like how you included that teachers should consider low tech devices first before moving on to high tech devices. I feel it is very easy for IEP teams to suggest iPads or other tablet devices before considering other low-tech options first.
