Robot teleoperation systems have been limited in their utility due to the need for operator motion, lack of portability and limitation to singular input modalities. In this article, the design and construction of a dual-mode human machine interface system for robot teleoperation addressing all these issues is presented. The interface is capable of directing robotic devices in response to tongue movement and/or speech without insertion of any device in the vicinity of the oral cavity. The interface is centered on the unique properties of the human ear as an acoustic output device. Specifically, we present: (1) an analysis of the sensitivity of human ear canals as acoustic output device; (2) the design of a new sensor for monitoring airflow in the aural canal; (3) pattern recognition procedures for recognition of both speech and tongue movement by monitoring aural flow across several human test subjects; and (4) a conceptual design and simulation of the machine interface system. We believe this work will lay the foundation for a new generation of human machine interface systems for all manner of robotic applications.

The focus of this research is to address the criticality and vulnerability of commercial shipping in the Straits of Mallacca by designing and evaluating competing systems architectures that could provide sufficient maritime domain protection. The category of primary concern was the introduction of a weapon of mass destruction (WMD) in a cargo container. The Maritime Domain Protection (MDP) physical architecture alternatives combined five separate systems: 1) a land-based cargo inspection system, 2) a sensor system, 3) a C3I (command and control, communications, and intelligence) system, 4) a force response system, and 5) a sea-based cargo inspection system. Individual models for each system were developed and combined into an overarching integrated architecture model to evaluate overall performance. Study results based on current technology showed that while solutions were found to effectively reduce risk in the WMD threat scenario, effective suppression came at great expense and included the participation of commercial shipping companies. A range of alternative cost-effective solutions were also found, but with limited performance. Future work involves using the developed architecture as a test bed for evaluating the overall impact and effectiveness of new technologies and research (such as smart containers) on MDP and homeland security.
