Evaluation of the CyberGlove(TM) as a Whole Hand Input Device

We present a careful evaluation of the sensor characteristics of the CyberGlove(TM) model CG1801 whole hand input device. In particular, we conducted an experimental study that investigated level of sensitivity of the sensors, their performance in recognized angles, and factors that affect accuracy of recognition of flexion measurements. Among our results, we show that hand size differences between the subjects of the study did not have a statisical affect on the accuracy of the device. We also analyzed the effect of differect software calibration approaches on accuracy of the sensors

The Simple Virtual Environment Library: Verson 2.0 Users Guide

The Simple Virtual Environments (SVE) C library provides a framework for the development of virtual environment (VE) applications. The library provides the default components of simple VE applications (such as fly-throughs), allowing these applications to be quickly implemented, and allows applications to selectively alter, enhance, or replace components such as user interactions, animations, rendering, and input device polling. The library also allows the hardware and software configuration (devices used and placement in the workspace, location of remote servers, directories, etc.) to be given at run-time using an initialization file. Therefore, SVE provides support for rapid prototyping as well as complete implementation of simple and complex VE applications

The Behavior of Interchange Heterozygotes in Oenothera

Virtual environment (VE) applications involve many different tasks, including interfacing with input and output devices, providing responsive user interaction, and simulating a dynamic environment. The variety and number of tasks lends the application to a distributed computing system, where different tasks are performed by different computing resources. A critical issue that arises from such a design is how information is communicated between tasks. In particular, for virtual environments, how information is communicated promptly is the critical issue. In this work, we describe a pattern of communication common between VE tasks which is not addressed by other communication protocols, namely the communication of state information that continuously changes. We describe a new protocol based on an updatable queue abstraction which allows obsolete state information to be discarded, and compare a prototype implementation of that abstraction with a standard communication protocol

The Simple Virtual Environment Library

The Simple Virtual Environments C library (SVE) provides basic functions to create virtual reality applications on Silicon Graphics workstations, including load/save/render routines of (hierarchical grouped) objects and an event-callback mechanism.It also provides several default callback routines to minimize the programming effort needed for an average VR application (like walkthroughs). The functionality of the current version is rather moderate, but is easy to use and extendable to personal needs

Consequences of CKD on Functioning

CKD is highly prevalent in the U.S. and throughout the world,(1) with approximately 13% of adults affected.(2) In addition, according to recent estimates, almost half of patients with CKD stage 3-5 are 70 years of age or older.(2) In the United States, the number of prevalent ESRD cases continues to rise in patients aged over 65. In light of the demographic characteristics of patients with CKD and ESRD, there has been considerable focus on associations between CKD and cardiovascular outcomes.(3) Until recently, less attention had been paid to other consequences of CKD in general and among older individuals with CKD in particular, but there is now solid evidence linking CKD with impairments of physical function, cognitive function, and emotional function and quality of life. This review will summarize available literature on these topics, focusing specifically on physical functioning and frailty; cognitive function; emotional health, including depression and anxiety; and health-related quality of life
