Impact Computing Corporation apply technical expertise spanning the areas of visualization, geographic information systems (GIS), user interface design, modeling and simulation, web technologies, and advanced R&D for a variety of commercial and government customers. Graphical User Interface (GUI) Design is highly "user-centric", relying heavily on rapid prototyping and user feedback to ensure an operationally relevant, intuitive and easy-to-use solution. Impact is actively involved in the development of advanced capabilities for the modeling and simulation domain, such as course of action (COA) analysis and optimization, semantic mediation using probabilistic ontologies, sensitivity and stochastic analysis services, and modeling of cognitive processes such as deception. The firm is able to analyze very complex, multi-dimensional datasets iin order to design innovative visualization paradigms that help users rapidly extract actionable information. Situational awareness and spatio-temporal visualization are essential to applications as diverse as supply chain management, air traffic control, logistics, law enforcement, military combat, and homeland security. The Impact team possesses an extensive background in building effective GIS solutions for users across a wide array of these application domains. The Impact Computing team is experienced in developing robust Service Oriented Architectures (SOAs) with well-defined web service components and interfaces, particularly in architecting plug-and-play frameworks that allow for integrated use of a heterogeneous collection of software components and tools. Examples of the advanced R&D initiatives undertaken by Impact includes modeling of spatio-temporal dynamics, adaptive learning technologies, behavioral modeling and innovative extensions to the wiki paradigm
