Search User Interfaces

Abstract: This book focuses on the human users of search engines and the tool they use to interact with them: the search user interface. The truly worldwide reach of the Web has brought with it a new realization among computer scientists and laypeople of the enormous importance of usability and user interface design. In the last ten years, much has become understood about what works in search interfaces from a usability perspective, and what does not. Researchers and practitioners have developed a wide range of innovative interface ideas, but only the most broadly acceptable make their way into major web search engines. This book summarizes these developments, presenting the state of the art of search interface design, both in academic research and in deployment in commercial systems. Many books describe the algorithms behind search engines and information retrieval systems, but the unique focus of this book is specifically on the user interface. It will be welcomed by industry professionals who design systems that use search interfaces as well as graduate students and academic researchers who investigate information systems.

User interface for presenting media information

Abstract: A user interface and methods for using a user interface for controlling processing of time-based media files. In one exemplary method, a graphical representation of a time line for a time-based media is displayed along with a graphical representation of a current time along the graphical representation of the time line. A start graphical indicator and a stop graphical indicator is also displayed along the graphical representation of the time line. A portion of the time-based media may be selected for presentation by dragging or positioning at least one of the start graphical indicator and the stop graphical indicator along the graphical representation of the time line. In another aspect of the invention, an exemplary method allows for the adaptive control of a portion of the interface which indicates time relating to a time-based media. An input speed is determined where this input is to change the portion and the rate at which the change to this portion occurs is dependent upon the input speed. Other aspects of the present invention relating to the interface for controlling the processing of time-based media files are also described.

Combining gestures and direct manipulation

Abstract: A gesture, as the term is used here, is a handmade mark used to give a command to a computer. The attributes of the gesture (its location, size, extent, orientation, and dynamic properties) can be mapped to parameters of the command. An operation, operands, and parameters can all be communicated simultaneously with a single, intuitive, easily drawn gesture. This makes gesturing an attractive interaction teehnique. ~pically, agestural interactions completed (e.g. the styIus is lifted) before the the gesture is classified, its attributes computed, and the intended command performed. There is no opportunity for the interactive manipulation of parameters in the presence of application feedback that is typical of drag operations indirect manipulation interfaces. This lack of continuous feedback during the interaction makes the use of gestures awkward for tasks that require such feedback, The video presents a two-phase interaction technique that combines gesture and direct manipulation. A two-phase interaction begins with a gesture, which is recognized during the interaction (e.g. while the stylus is still touching the writing surface). After recognition, the application is informed and the interaction continues, allowing the user to manipulate parameters interactively, The result is a powerful interaction which combines the advantages of gesturing and direct manipulation.

JUPlTER: a telephone-based conversational interface for weather information

Abstract: In early 1997, our group initiated a project to develop JUPITER, a conversational interface that allows users to obtain worldwide weather forecast information over the telephone using spoken dialogue. It has served as the primary research platform for our group on many issues related to human language technology, including telephone-based speech recognition, robust language understanding, language generation, dialogue modeling, and multilingual interfaces. Over a two year period since coming online in May 1997, JUPITER has received, via a toll-free number in North America, over 30000 calls (totaling over 180000 utterances), mostly from naive users. The purpose of this paper is to describe our development effort in terms of the underlying human language technologies as well as other system-related issues such as utterance rejection and content harvesting. We also present some evaluation results on the system and its components.

A picture of search

Abstract: We survey many of the measures used to describe and evaluate the efficiency and effectiveness of large-scale search services. These measures, herein visualized versus verbalized, reveal a domain rich in complexity and scale. We cover six principle facets of search: the query space, users' query sessions, user behavior, operational requirements, the content space, and user demographics. While this paper focuses on measures, the measurements themselves raise questions and suggest avenues of further investigation.
