This paper discusses the motivation, design, implementation, and some sample applications of a new input device, called the Monkey, that can be used for real-time control of digital human models.
We present the case study of a complex, mixed-initiative scheduling system to illustrate <i>Work-Centered Design</i> (WCD), a new approach for the design of information systems. WCD is based on theory of distributed cognition and extends established user-centered methods with abstract task modeling, using innovative techniques for work ontology and… (More)
This tutorial presents many of the user interface issues a developer must deal with when developing virtual reality (VR) systems, including virtual body definition and control, choosing interaction devices and techniques, system evaluation criteria, and choosing a development environment.
Carroll and Campbell  and Suchman  have also argued that software embodies user work processes, but stopped short of examining the profound implications for organizations and businesses. They need to respond to accelerating change in the world by improving their work processes continuously, and in some cases by reengineering them completely. Often an… (More)
Tissue expansion is an ideal reconstructive procedure for burn scar alopecia. Donor tissue is generated in situ, allowing for the use of hair-bearing tissue to reconstruct an area of alopecia. The process of tissue expansion results in a redistribution of the remaining hair follicles to replace the area of alopecia.
Bony fish swim with a level of agility that is unmatched in human-developed systems. This is due, in part, to the ability of the fish to carefully control hydrodynamic forces through the active modulation of the fins' kinematics and mechanical properties. To better understand how fish produce and control forces, biorobotic models of the bluegill sunfish's… (More)
Our objective was to demonstrate how software methods for information systems can function as an integral part of advanced methods for reengineering and continuously improving business processes. We report the feasibility of version 0.3 of the tools for a User-Centered Development Environment with Distributed Application Services. Our approach was to derive… (More)
Since the summer of 1994, a group of partners, led by Boeing and including Carnegie Mellon University, Virtual Vision, and Honeywell have developed or provided significant design input on several generations of wearable computer systems, head-mounted displays (HMDs), and field-tested several application prototypes using these systems. Some of these… (More)
