Research Paper How do legally blind people “see”? In the United States, to be considered legally blind, a person must have the low visual acuity of 20/400 or lower. Not only does the person have almost an inability to see, but there are barely any treatments that can fix or correct blindness. That, today, is a huge problem as many activities of our generation involve sight because people considered normal do not have blindness and sight is huge and very important sense, which cripples the visually impaired as they cannot do many things without their sense of vision. And not only that, but there are very little ways for people diagnosed with blindness to fit back into society. …show more content…
Sensors can detect, predict, change factors, and have long lives and reliability. In all, there are five main types of sensors, temperature, IR, UV, touch, and proximity. They all are very different and play very different roles in a variety of things. The first type, IR sensors, emit radiation to detect an environment’s phase. All objects that are infrared emit thermal radiation, but IR sensors emit radiation not visible to humans. IR sensors are used in several ways from heating ice and food, to meteorology, to even identify molecules and their bonds in spectroscopy (engineersgarage.com). What makes these types of sensors so reliable is that they ready to be bought anywhere and they are easy to interface. UV sensors, or ultraviolet sensors, measure the power of ultraviolet radiation. They are a form of electromagnetic radiation that has longer than x-ray wavelengths and only receive one type of signal, as well as send other types of signals back. Another type of sensor, proximity sensors, can detect objects without touching them. They are long lasting and reliable because they do not make any contact with the object it is detecting. The different types of proximity sensors include capacitive proximity sensors, ultrasonic proximity sensors, and inductive proximity sensors. It works by sending electromagnetic radiation then awaits the signal to see if anything changed or different
