Abstract DECAFF is a method for design and control of haptic interfaces that utilizes a DE-Coupled Actuator and Feed-Forward control. In this paper results of an experimental investigation are presented that quantify improved human haptic perception while using the DECAFF system, compared to the traditional haptic interface design and control systems. Perception improvements include the increased stability for rigid surfaces and increased ability of subjects to accurately identify initial contact with virtual surface boundaries. Traditional haptic interfaces employ an actuator directly coupled to the human operator that provides a force proportional to wall penetration distance and velocity. The DECAFF paradigm for design and control of haptic displays utilizes a de-coupled actuator and pre-contact distance sensing as a feed forward control term to improve stability and response performance. A human perception experiment has been performed that compares the touch sensation of the subjects for both the DECAFF system and traditional approaches to haptic display. In the human factors study the quality of rigid body display is evaluated in addition to the sensitivity of touch experienced by the subjects while making initial contact with virtual surfaces.

A number of alternative environmental enforcement tools are available that may be used to enhance the environmental enforcement effort in South Africa.  Current debate focuses on which tools work effectively and the reasons for their success.  The debate is however dominated by issues concerning policy challenges, such as the adoption of alternative tools and necessary arrangements to ensure these tools contribute to overall environmental enforcement performance.  In order to contribute to the debate and stimulate further debate, this article offers a typology of alternative enforcement tool categories, lists the generally argued benefits and disadvantages of both command and control approaches and alternative enforcement tools, offers framework conditions for the successful adoption and use of some of the enforcement tools, and explores empirical and other evidence to determine whether environmental management systems are adequately able to drive sustained and consistent legal compliance.  A South African case study is also presented to illustrate the manner in which a combination of alternative enforcement tools may be integrated with command and control tools to ensure consistent and sustained legal compliance.

The process of training teams increasingly occurs in synthetic environments. However, it is often still modeled after live team training, including the disadvantages of live training, for example, the fact that all teammates must be available. This paper explores overcoming the disadvantages of human teammates in training teams in synthetic environments, while keeping the advantages of learning in a collaborative and cooperative fashion. Simulated teammates are a promising alternative because they are always available, may be modeled after experienced training personnel, and may be more cost effective in the long run. This paper details a research approach towards the definition of requirements for simulated teammates. In our approach, we carry out a set of experiments using confederates as simulated teammates, in a well-controlled simulation of a military command-and-control task The results of a first experiment show slightly better teamwork skills for those teams trained with simulated teammates.
