Assessing the effectiveness of pen-based input queries

In this poster, we describe an experiment exploring the effectiveness of a pen based text input device for use in query construction. Standard TREC queries were written, recognised, and subsequently retrieved upon. Comparisons between retrieval effectiveness based on the recognised writing and a typed text baseline were made. On average, effectiveness was 75% of the baseline. Other statistics on the quality and nature of recognition are also reported. Categories and Subject Descriptors H.3.3 [Information Storage and Retrieval]: Information Search and Retrieval – search process; H.5.2 [Information Interfaces and Presentation]: User Interfaces – input devices and strategies; I.7.5 [Document and Text Processing]: Document Capture – graphics recognition and interpretation. General Terms Measurement, Performance, Experimentation. Keywords Tablet PC, handwriting recognition.
