The WOZ Math Recognizer: A Mathematics Handwriting Recognition Wizard of Oz Tool

by Jared N. Bott, Joseph J. Laviola , 2011
"... Mathematical handwriting recognition is an important method of mathematics input for computers. While strides in recognition have been made in recent years, recognition is still at a level where mistakes are common and often inexplicable from the user’s point-of-view. As a result, recognition mistak ..."

mistakes can cause user distraction and frustration. In order to explore this area, we developed a Wizard of Oz mathematics handwriting recognition tool, the WOZ Math Recognizer. The WOZ Math Recognizer supports controlled symbol and position accuracy and batch and real-time recognition modes. We present

Wizard of Oz Experiments

SketchWizard: Wizard of Oz Prototyping of Pen-based User Interfaces

by Richard C. Davis, T. Scott Saponas, Michael Shilman, James A. Landay - IN PROC. OF UIST , 2007
"... SketchWizard allows designers to create Wizard of Oz prototypes of pen-based user interfaces in the early stages of design. In the past, designers have been inhibited from participating in the design of pen-based interfaces because of the inadequacy of paper prototypes and the difficulty of developi ..."

describes the SketchWizard system and presents two evaluations of our approach. The first is an early feasibility study in which Wizard of Oz was used to prototype a pen-based user interface. The second is a laboratory study in which designers used SketchWizard to simulate existing pen-based interfaces

Children’s Emotion Recognition in an Intelligent Tutoring Scenario

by Tong Zhang, Mark Hasegawa-johnson, Stephen E. Levinson
"... This paper presents an approach to automatically recognize emotion which children exhibit in an intelligent tutoring system. Emotion recognition can assist the computer agent to adapt its tutorial strategies to improve the efficiency of knowledge transmission. In this study, we detect three emotiona ..."

) integrates the various information sources together for final decision. The effectiveness of the proposed approach has been tested on data collected by Wizard-of-Oz (WoZ) experiments. Our emotion recognition was speaker-independent, and yielded 91.3 % accuracy. The test results showed that the spectral

Recognition of Emotion in a Realistic Dialogue Scenario

by R. Huber, A. Batliner, J. Buckow, E. Nöth, V. Warnke, H. Niemann - in Proc. Int. Conf. on Spoken Language Processing , 2000
"... Nowadays modern automatic dialogue systems are able to understand complex sentences instead of only a few commands like Stop or No. In a call-center, such a system should be able to determine in a critical phase of the dialogue if the call should be passed over to a human operator. Such a critical p ..."

Bootstrapping language models for dialogue systems

by Karl Weilhammer, Matthew N. Stuttle, Steve Young - In Proc. of the International Conference on Spoken Language Processing. Version: 1.0 (Final) Distribution: public TALK D6.4 (Part II) 20th December 2006 Page 59/60
"... We report results on rapidly building language models for dialogue systems. Our base line is a recogniser using a grammar network. We show that we can almost halve the word error rate (WER) by combining language models generated from a simple task grammar with a standard speech corpus and data colle ..."

collected from the web using a sentence selection algorithm based on relative perplexity. This model compares very well to a language model using “in-domain ” data from a Wizard Of Oz (WOZ) collection. We strongly advocate the use of statistical language models (SLMs) in speech recognisers for dialogue
