The Safe and Sound wristband is supposed to promote the idea that sensory-friendly environments for people with varying sensitivities to light, sound, smells, and other things should be supported. This device focuses on sound-sensitivity for those with autism. The wristband collects analog data provided by spatial sounds and converts it to a sort-of meter made by the pixel graphic on the Circuit Playground Express. This acts as a visual representation that lets others know if an area may be too loud for the individual. The sensitivity may also be altered and fine-tuned to each specific user, as every user will have a varying sensitivity.
Many people do not care about others' sensitivity or ask, "why should I care?" To me, we should be striving to make the world a more comfortable place for everyone, including those with disabilities. Taking extra steps to ensure areas are safe spaces for these individuals may seem small to us but are tremendous to those that need them. The first step to making this sort of change is by raising awareness and making sure others are aware to begin with.
