Sensory substitution is when one of your senses gets replaced by another sense. For example, you might use your sense of sight instead of your sense of touch to tell where something is, or to recognize shapes and objects. This is done by wearing special tools, like goggles or gloves, that turn one type of information into another type of information. For example, a glove might have sensors that turn vibration into light, so instead of feeling something, you can see it!
