Systems, methods and techniques for providing sensory input to a subject through non-invasive brain stimulation are generally described. In some examples, an input signal related to an environment may be received. In various further examples, a communication to the subject may be determined in response to the input signal. In some examples, an output signal corresponding to the determined communication may be generated. Some further examples may comprise non-invasively stimulating a portion of the subject's brain with the output signal with a stimulation subsystem positioned outside of the subject's scalp. In various examples, the stimulation of the portion of the subject's brain may be effective in producing a sensory response perceivable by the subject.
