The HCC Multimodal Interfaces (MI) technical area is about integrating humans, computational devices, and environments in a seamless manner, leveraging the unique capabilities of each to satisfy system-level requirements. MI technologies include speech and natural language interfaces, multimedia systems, adaptive and intelligent interfaces and displays, ubiquitous computing, and mobile and wearable computing. Investments are selective, guided by NASA requirements.
NASA's planned missions will require dramatic advances in the functional bandwidth and reliability of operator-system interfaces. We must find ways to couple humans and computers into cooperative, efficient systems. Team interfaces that reflect mixed-initiative models of content, activity, and dialogue will require advances in spoken and visual languages, flexible movement among levels of abstraction, and expert coordination of multiple representations.
Multimodal interfaces go far beyond simple displays and voice-response systems. They help decision makers accomplish high-bandwidth, heterogeneous, real-time data integration and interpretation. Applications include remote science, model-based (predictive) control, onboard system management and procedure execution, and information management for ground operations.
A representative example might be an intelligent maneuvering system for the International Space Station. The ISS will offer serious challenges to humans performing intricate docking and assembly maneuvers. An intelligent maneuvering system could enhance the performance of astronauts by integrating telerobotic systems with software for monitoring, scheduling, and decision support. Such an intelligent system would reduce the probability of mishaps, while freeing operators from routine monitoring and manipulation tasks.
Another broad area of application is enhancement of air traffic safety and capacity. A new generation of human-centered performance aids is needed both on the ground and in the air. In the cockpit, a new generation of displays and interfaces could mitigate information overload and improve situation awareness. NASA is also developing human-centered systems that can assist pilots in flying severely damaged aircraft by reconfiguring the flight-control computer system.
Interfaces must be useful even under difficult conditions, and their safety and reliability must be established in advance through rigorous design and testing. Engineering design of such flexible, robust performance-enhancement systems is beyond the state of the art. MI tasks are developing better models of attention, memory, conceptual structure, decision-making, learning, and higher-level perception needed for principled design and testing of novel human-computer systems. These will permit early, reliable design choices (minimizing life cycle cost) and reduce system risk.
