Submersible Audio Light Sensor vs VO Starter

The Submersible Audio Light Sensor (SALS) app works with the SALS probe, a Bluetooth Low Energy device, purchased separately from the American Printing House for the Blind. One end of the probe detects light in either air or liquids and the other end coverts detected light to sound (in the form of a tone) and sends the data to the app downloaded on an iPhone or iPad. Use of the app and probe alert a student with visual impairment or blindness that a chemical reaction has taken place (e.g., a precipitate has formed, pH has changed) in a beaker or test tube. Differences in luminance between the surfaces of objects in air (e.g., rocks or pH paper) can also be detected by the probe and app.

VO Starter teaches new blind and visually impaired iOS users how to use their device with Apple's built in screen reader, VoiceOver. Learning a new device can be challenging, and learning a new device and a new screen reader can take time and patience. VO Starter provides a step by step guide to learn to use the iPhone, while keeping lessons quick, and easy to learn.
