On the application of text input metrics to handwritten text input
Janet C. Read · 2005
This paper describes the current metrics used in text input research, considering those used for discrete text input as well as those used for spoken input. It examines how these metrics might be used for handwritten text input and provides some thoughts about different metrics that might allow for a more fine grained evaluation of recognition improvement or input accuracy. Text Input Methods Users spend a significant amount of carrying out text input activities. This time comprises thinking time, input time, and correction time and, more often than not, this time is spent at a keyboard, either a QWERTY keyboard or a reduced keyboard (as found on mobile phones). It is therefore, unsurprising that most of the work on text input has focussed on these two paradigms. There are several other methods for entering text at a computer, these include gaze typing and spoken input and, with the advent of the PDA and, more recently, the tablet PC, users can use handwritten text that is created with a stylus or pen.
