Stylus-Based User Interface for Text: Entry and Editing

摘要

In any new system, the methods by which a user manipulates textual informationare important. This thesis explores the utility of stylus-based input for several text-related tasks, and informally studies a number of user interaction techniques. We describe a system for entering text with a stylus and investigate user interface techniques for interfacing with a text recognizer, concluding that a stylus is a feasible input device for entering small amounts of text. We also implement a simple text editing system utilizing gestural commands and explore the interactions of a stylus with some additional user interface techniques: scrolling and on-screen buttons. We discuss some alternatives in the design of such an editing system, including the use of 'markup editing.' We conclude that stylus-based systems can be easy to use and learn and lend themselves to the incorporation of knowledge about users' tasks. (Copyright (c) 1991 Aaron Goodisman.)
