Americans with Disabilities Act - Compliance Assessment Toolkit on Smartphone

The Americans With Disabilities Act (ADA) and other accessibility standards specify the requirements for assessing the architectural barriers for the built environment. And, the ADA -- Compliance Assessment Toolkit (ADACAT)provides simple pass-fail assessments of those requirements. Measurement Kit is the principal component of the ADACAT, which consists of various measuring instruments like, measuring tape, sound-level meter, light-level meter, magic slope block, etc. In this essay, we show that most of the instruments in the Measurement Kit can be effectively implemented as a software application on a smartphone equipped with sensors like, accelerometer, gyroscope, and microphone. Detailed algorithms have been presented and the experimental results show that an iPhone or iPod Touch 4:0 application can serve as measuring tape, sound-level meter, as well as slope meter, making the ADACAT both cheaper and more portable.
