Building on the observation that finger orientation is an inherent part of human's interaction in the real world, exploiting finger orientation for multitouch tabletop interaction would facilitate more natural interaction techniques. We motivate this by means of examples where the finger orientation improves or enriches interaction. Afterwards, we present a simple and fast approach to detect th...

There are a variety of tasks in which the amount of lime available to make decisions does not always allow a careful consideration of all oi the options. AIRPLAN is being developed to assist with one such task, managing the launch and recovery of aircraft on a carrier. This paper describes attempts to represent AIRPLAN's knowledge in a way that enables it to provide as much assistance as possib...

The purpose of this paper is to provide a synthesis and overview of a multipart research study involving the design, exploration, and validation of an enterprise architecture and framework. The methodology includes the use of two case studies and validation through a national conference. While the authors have reported on the elements of this research, only recently has its completion allowed f...

The BSP model provides a unified framework for the design and programming of scalable servers for time-critical computing. This paper describes some of the recent developments in the area of

Three dimensional user interfaces can help users in time-critical situations to improve their ability to solve problems. But they also may distract them from fulfilling their tasks with efficiency and effectiveness. This requests to control and limit the distraction caused by usage of those interfaces. Therefore it is necessary to measure and compare distraction caused by three dimensional user...
