For privacy protection, we should not collect the exact key the user input. However, to analyze the mood and cognition condition of the user we need more information. So I classified the data and put them into the following categories: Alpha-Numeric, Space, Backspace, switchToNumber, switchToLetter, Punctuations, Symbols.

Alpha-Numeric: all numbers and the English alphabet.

Space: the "space" key

Backspace: the "Backspace" key

switchToNumber: the "switchToNumber" key, this key enable the user to switch to the number keyboard

switchToLetter: the "switchToLetter" key, this key enable the user to switch to the letter keyboard

Punctuations: 14 punctuations in English grammar: (.?!,:;-[]{}()'")
