Existing brain-computer interface (BCI) control of highly dexterous robotic manipulators and prosthetic devices typically rely solely on neural decode algorithms to determine the user's intended motion. Although these approaches have made significant progress in the ability to control high degree of freedom (DOF) manipulators, the ability to perform activities of daily living (ADL) is still an ongoing...
The ability of robotic systems to effectively address disaster scenarios that are potentially dangerous for human operators is continuing to grow as a research and development field. This leverages research from areas such as bimanual manipulation, dexterous grasping, bipedal locomotion, computer vision, sensing, object segmentation, varying degrees of autonomy, and operator control/feedback. This...
This paper presents the experimental validation of software-based safety features implemented during the control of a prosthetic limb in self-feeding tasks with a human patient. To ensure safe operation during patient controlled movements of the limb, velocity-based virtual fixtures are constructed with respect to the patient's location and orientation relative to the limb. These imposed virtual fixtures...
In 2005, 52% of taxpayers filed their federal returns electronically. This is far short of the IRS goal of having 80% of returns filed electronically by 2007. Using the e-commerce technology adoption literature, this exploratory study investigates factors that differentiate e-filers from non-e-filers. People who e-file perceived e-filing to be less useful measured as convenience, and less expensive...
