Today, people are able to input data into calculating machines through speech and gestures, including drawing and typing.

Additionally, machines can gather biomarker data produced by the person. We can also issue a simple command to transmit a large block of previously prepared data.

These input mechanisms have certain potential disadvantages:

-They are somewhat inaccurate -They are slow. (Although triggering a larger file transmission makes up for the speed deficit, under many circumstances.)

We can receive more information through sensory input than we can transmit out.
