Existing Formula Entry Methods

This section discusses existing methods for entering formulae into a computer. Take the following formula as an example:

$$\int^{20}_{10}{\frac{4x^3}{\ln{x}}}dx$$

Either the formula can be turned into some linear form, and then typed at the keyboard, or some system could be used where the 2D nature of the formula is preserved.

The paper by Kajler and Soiffer  gives a good overview of the techniques and considerations involved in making interfaces for computer algebra systems. They predominantly discuss window based, template style entry systems, though they do have a section on alternative input methods, such as pen and tablet or voice.
