Welbourn, L. K. and Whitrow, R. (1988): A Gesture Based Text Editor. In: Jones, Dylan M. and Winder, R. (eds.) Proceedings of the Fourth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers IV August 5-9, 1988, University of Manchester, UK. pp. 363-371.

“This paper describes a text editor which has been designed to mimic the usual pen and paper type of editing. Hand-drawn gestures are used to specify the editing task. The use of gestures as an interface becomes more important with the advent of the electronic paper. The user specifies the editing task and its range by drawing the gesture on a tablet. The 'ink' of the pen appears on a screen, allowing the user to see what is drawn. The recognition of the gesture is on-line in its nature and the results of the edit are displayed immediately. Typically, two horizontal lines drawn through a word will be recognised as a delete operation, and the word will be removed from the display. The editing operations described include deletion, insertion, new paragraph, block moves and page formatting. The editor has been designed to work on both cursive and ascii text. The output document from the editor is directed to a character recogniser for recognition purposes. The choice of gestures and their recognition is described and discussion of the user acceptability given.”
