We describe the use of human cortical control signals to operate two assistive technology tools--a virtual keyboard speller and a computer-simulated digit. The cortical signals used for control are local field potentials recorded through an implanted neurotrophic electrode. In this system, the patients' cortical signals are transmitted wirelessly to a(More)
The relationship between emotions and learning was investigated by tracking the emotions that college students experienced while learning about computer literacy with AutoTutor. AutoTutor is an animated pedagogical agent that holds a conversation in natural language, with spoken contributions by the learner. Thirty students completed a multiple-choice(More)
Individuals with profound paralysis and mutism require a communication channel. Traditional assistive technology devices eventually fail, especially in the case of amyotrophic lateral sclerosis (ALS) subjects who gradually become totally locked-in. A direct brain-to-computer interface that provides switch functions can provide a direct communication channel(More)

OBJECTIVE To determine whether or not patients undergoing procedures in the Day Surgery Unit (DSU) are satisfied with the environment and the care received. METHOD Discharge questionnaire. RESULTS Overall, patients treated in the Day Surgery Unit were very pleased with the care that they received. As a result of concerns expressed in a pilot study,(More)
Local land-use policy is increasingly being recognized as fundamental to biodiversity conservation in the United States. Many planners and conservation scientists have called for broader use of planning and regulatory tools to support the conservation of biodiversity at local scales. Yet little is known about the pervasiveness of these practices. We(More)
UNLABELLED The term insufficiency fracture implies inadequate bone and is applied to some subchondral knee magnetic resonance images. We reviewed bone mineral density, body mass index, meniscal extrusion, comorbidities, and demographics in 32 knee insufficiency fracture patients. Only five were osteoporotic. Meniscal extrusion was predominant. PURPOSE The(More)
The paper presents a study in which participants learned computer literacy by having a spoken conversation with AutoTutor, an intelligent tutoring system with conversational dialogue. Thirty students completed a multiple-choice pre-test, a 35-minute training session, and a multiple-choice post-test. After completing the post-test, students reviewed their(More)
