An investigation on data entry effectiveness & efficiency
Developing fast and efficient means for text entry is one of the most pressing research topics in today!
Although the QWERTY layout is entrenched for physical keyboards, soft keyboards are easy to implement and customize.
To develop a statistically reliable analysis of possible factors that may have influence on the input efficiency and error rateof the soft keyboard and give design guideline on this issue.
Mouse C/R ratio
Large: the size of keys on standard physical keyboard
Small: that of general electronic dictionaries
Mouse C/R ratio
High: the highest in the tested computer.
Low: adjusted one which is the lower bound that one can bear
Click “Backspace” when ever testee notices error and count the number of “Backspace” clicked as error
Errors may not be noticed immediately.
Sequence of the words or letters may be changed, due to other reasons unrelated to the keyboard.
