SSPT
(Single Switch Performance Test)
Many people with disabilities use single switches to control various items of assistive technology. Overall performance of an assistive technology system is determined by many factors, including how well the individual can activate the switch. The choice and positioning of switches is most effectively accomplished when performance is measured.
SSPT is software to facilitate measurement of the ability to activate a single switch. SSPT software measures the average time required to activate or release the switch (following visual and/or audio prompts) and also can measure the speed of repetitive activations.
SSPT is available in two forms. The Visual Basic program can run on a PC. The Java program can run on a Macintosh or on a PC that has the Java Runtime Environment. SSPT was developed by computer science students at Millersville University of Pennsylvania under the supervision of Blaise Liffick, Ph.D. and is distributed free of charge.
The switch under test is connected to the computer as a mouse button. This is generally done with a traditional computer mouse that has been modified by adding a switch jack. See below.
