The NavChair Assistive Wheelchair Navigation System
Simon P. Levine,David A. Bell,Lincoln A. Jaros,Richard C. Simpson,Yoram Koren,Johann Borenstein +5 more
TL;DR: The NavChair Assistive Wheelchair Navigation System is being developed to reduce the cognitive and physical requirements of operating a power wheelchair for people with wide ranging impairments that limit their access to powered mobility.
Proceedings ArticleDOI
An assistive navigation system for wheelchairs based upon mobile robot obstacle avoidance
TL;DR: The VFH method has been adapted for use in human-machine systems and the shortcomings of the wheelchair platform have been overcome, and interesting aspects of its application to a power wheelchair are described.
PatentDOI
Method for adaptive control of human-machine systems employing disturbance response
TL;DR: Adaptive control of a system with a human in the loop is accomplished by sensing human operator reactions to a disturbance in the system and characterizing the operator response to the disturbance as discussed by the authors. But the human response is characterized in one of several forms by predicting a response based on a model quantifying a response on statistics or merely measuring a response for accumulation of data to be employed by an artificial intelligent system.
Patent
Method and system for sharing object information
TL;DR: In this article, a system for locating and identifying categories of biological objects at a geographical location is described, where a visual or an aural characteristic of one or more biological objects sighted is compared with visual or aural characteristics of known biological objects stored in a database.
Proceedings ArticleDOI
An identification technique for adaptive shared control in human-machine systems
TL;DR: In this paper, the authors present a modeling approach to monitor human control behavior in real time, and preliminary experimental results evaluate its ability to distinguish human control behaviors in a simulated system.
