From the Publisher:
Written by the author of the best-selling HyperText & HyperMedia, this book provides an excellent guide to the methods of usability engineering. Special features: emphasizes cost-effective methods that will help developers improve their user interfaces immediately, shows you how to avoid the four most frequently listed reasons for delay in software projects, provides step-by-step information about which methods to use at various stages during the development life cycle, and offers information on the unique issues relating to informational usability. You do not need to have previous knowledge of usability to implement the methods provided, yet all of the latest research is covered.

Usability Engineering

Usability Engineering: Scenario-Based Development of Human-Computer Interaction is a radical departure from traditional books that emphasize theory and address experts. This book focuses on the realities of product development, showing how user interaction scenarios can make usability practices an integral part of interactive system development. As you'll learn, usability engineering is not the application of inflexible rules; it's a process of analysis, prototyping, and problem solving in which you evaluate tradeoffs, make reasoned decisions, and maximize the overall value of your product.

Usability Engineering: Scenario-Based Development of Human-Computer Interaction

User involvement is a widely accepted principle in development of usable systems. However, it is a vague concept covering many approaches. This study first clarifies the nature of user involvement and its expected benefits, and secondly reviews three streams of research, to evaluate the benefits and problems of varied user involvement approaches in practice. The particular focus of this study is on the early activities in the development process. An analysis of the literature suggests that user involvement has generally positive effects, especially on user satisfaction, and some evidence exists to suggest that taking users as a primary information source is an effective means of requirements capture. However, the role of users must be carefully considered and more cost-efficient practices are needed for gathering users' implicit needs and requirements in real product development contexts.

User involvement: A review of the benefits and challenges

A survey of seventy-seven highly motivated industrial designers and programmers indicates that the identification of specific, potential problems in a human-computer dialogue design is difficult.

A credit application and routing system includes a central processor having and executing a program. The system includes data input capabilities for selectively receiving credit application data from respective applicants at remote locations, and routing capabilities for selectively forwarding the credit application data to remote funding sources and selectively forwarding funding decision data from the funding sources to the respective applicants. The computer program includes routines for receiving a credit application from at least one remote application input and display device, for selectively forwarding a received credit application to at least one funding source, for receiving a funding decision from the at least one funding source, and for forwarding a received funding decision to the at least one remote application input and display device. The system can also obtain credit report data from credit bureaua, and analyze and summarize the credit report data. A computer readable storage medium has a substrate physically configured to represent the computer program which causes a computer to provide the credit application and routing system.

The novel notepad of the invention provides a convenient interface into the capabilities of computer technology from paper based information. The notepad has a form factor similar to a clipboard wherein the board portion includes a digitizing tablet and the clip portion includes an optical scanner. A battery-powered embedded processor and associated peripherals provide for capturing and storing information in a variety of forms including at least scanning information, digitized stylus information and audio annotation. An important feature of the invention is the linking of these different forms of information via software so that while the information is readily available for efficient processing, it is also combinable so as to recreate the annotated document through conventional means.

There was more than athletic talent being pressed to peak performance at the 1984 Olympic Games in Los Angeles. Behind the scenes, a multilingual Olympic Message System ran round-the-clock keeping more than 10,000 athletes and officials in contact with families and friends, both far and near.

An interactive computer system having a processor executing a target computer program, and having a speech recognizer for converting an utterance into a command signal for the target computer program. The target computer program has a series of active program states occurring over a series of time periods. At least a first active-state image is displayed for a first active state occurring during a first time period. At least one object displayed in the first active-state image is identified, and a list of one or more first active-state commands identifying functions which can be performed in the first active state of the target computer program is generated from the identified object. A first active-state vocabulary of acoustic command models for the first active state comprises the acoustic command models from a system vocabulary representing the first active-state commands. A speech recognizer measures the value of at least one feature of an utterance during each of a series of successive time intervals within the first time period to produce a series of feature signals. The measured feature signals are compared to each of the acoustic command models in the first active-state vocabulary to generate a match score for the utterance and each acoustic command model. The speech recognizer outputs a command signal corresponding to the command model from the first active-state vocabulary having the best match score.

Reliable and secure transmission of information over the Internet is provided in a financial transaction processing system. The system electronically integrates data captured in heterogeneous information systems and transmits that data reliably and securely over the Internet between multiple diverse servers. The system includes at least one local computer system which electronically captures information input by a user of the computer system. The local computer system can access one or more remote servers via the Internet for form a dynamically reconfigurable wide area network (WAN). The remote servers electronically transfer data to heterogeneous information systems translated into their natural communications protocol and data format.

The invention relates to a computer program product for a stylus-based user interface for computers. The invention is a process for separating a stylus-based application program from the procedures used to implement stylus-based, user driven error correction processes. This separation allows error correction procedures to be used by many applications, providing consistency in the user interface and saving application development costs through reuse of these procedures.
