Luz, Saturnino, Masoodian, Masood and Rogers, Bill (2008): Interactive visualisation techniques for dynamic speech transcription, correction and training. In: CHINZ08 - the ACM SIGCHI New Zealand Chapters International Conference on Computer-Human Interaction 2008. pp. 9-16. Available online
As performance gains in automatic speech recognition systems plateau, improvements to existing applications of speech recognition technology seem more likely to come from better user interface design than from further progress in core recognition components. Among all applications of speech recognition, the usability of systems for transcription of spontaneous speech is particularly sensitive to high word error rates. This paper presents a series of approaches to improving the usability of such applications. We propose new mechanisms for error correction, use of contextual information, and use of 3D visualisation techniques to improve user interaction with a recogniser and maximise the impact of user feedback. These proposals are illustrated through several prototypes which target tasks such as: off-line transcript editing, dynamic transcript editing, and real-time visualisation of recognition paths. An evaluation of our dynamic transcript editing system demonstrates the gains that can be made by adding the corrected words to the recogniser's dictionary and then propagating the user's corrections.

A set of user interface design techniques for computer-assisted speech transcription are presented and evaluated with respect to task performance and usability. These techniques include error-correction mechanisms which originated in dictation systems and audio editors as well as new techniques developed by us which exploit specific characteristics of existing speech recognition technologies in order to facilitate transcription in settings that typically yield considerable recognition inaccuracy, such as when the speech to be transcribed was produced by different speakers. In particular, we describe a mechanism for dynamic propagation of user feedback which progressively adapts the system to different speakers and lexical contexts. Results of usability and performance evaluation trials indicate that feedback propagation, menu-based correction coupled with keyboard interaction and text-driven audio playback are positively perceived by users and result in improved transcript accuracy.

Masoodian, Masood, McKoy, Sam and Rogers, Bill (2007): Hands-on sharing: collaborative document manipulation on a tabletop display using bare hands. In: Proceedings of CHINZ07, the ACM SIGCHI New Zealand Chapters International Conference on Computer-Human Interaction 1-4 July 2007, 2007, Hamilton, New Zealand. pp. 25-31. Available online
Working on electronic shared documents on a tabletop display is an effective form of collaborative work, which is likely to become a common practice in the future. A limiting factor in using tabletop displays at present, however, is their lack of support for multiple direct input by several users, or their reliance on expensive devices for supporting multiple user inputs. This paper describes a simple set of hardware and software solutions for creating a back-projection tabletop display with bare hand input mechanism to allow users to gesture at and select positions in a shared collaborative document. The system provides for a mixture of private and public workspaces for each collaborator.

Although the 2D desktop metaphor has been the dominating paradigm of user interfaces for over two decades, 3D models of interaction are becoming more feasible due to advances in computer output hardware and software technology. However, conventional input devices such as a mouse or track-pad generally restrict direct manipulation interaction to a 2D paradigm. More sophisticated 3D input devices such data-gloves have been available for some time, but these tend to be expensive or restrictive in their use. In this paper we describe a simple and inexpensive single camera-based video input system which allows 3D interaction with existing computer application using bare hands.

Apperley, Mark, Fletcher, Dale and Rogers, Bill (2002): The stretchable selection tool: an alternative to copy and paste. In Interacting with Computers, 14 (3) pp. 195-209
Copy and paste, or cut and paste, using a clipboard or paste buffer is the principal facility provided to users for transferring data between and within application software. This mechanism is clumsy to use where several pieces of information must be moved systematically, for example, when filling a form or building a table. We present an alternative, more natural user interface facility to make the task less onerous, and to provide improved visual feedback. Our mechanism -- the stretchable selection tool (SST) -- is a semi-transparent overlay augmenting the mouse pointer to automate paste operations and provide information to prompt the user. Two prototype implementations are described, one of which functions in a collaborative software environment allowing users to cooperate on multiple copy/paste operations. We also present the results of an informal user evaluation contrasting the SST with traditional cut and paste, and with another multiple copy/paste system.
