1. A method comprising:
- generating user output data;
converting the user output data to representations corresponding to light signals; and
performing control functions to at least two current sources to cause generation of electrical outputs in the form of at least a balanced differential signal which, when applied to the skin of a user, stimulate an optic nerve of the user so as to cause the user to perceive the light signals.

Abstract
Systems and techniques for providing data to a user in the form of perceived light signals caused by transcutaneous stimulation of the user'"'"'s optic nerve. User output data, suitably representing data collected, generated, or processed by a data processing device, is used to generate user output data. The user output data is converted to representations corresponding to light signals, and control functions are performed to cause generation of electrical impulses which, when applied to the skin of a user, stimulate the optic nerve of the user so as to cause the user to perceive the light signals.
