This paper presents a new haptic rendering method for streaming point cloud data. It provides haptic rendering of moving physical objects using data obtained from RGB-D cameras. Thus, real-time haptic interaction with moving objects can be achieved using noncontact sensors. This method extends "virtual coupling"-based proxy methods in a way that does not(More)
The empirical mode decomposition (EMD) has seen widespread use for analysis of nonlinear and nonstationary time-series. Despite some practical success, it lacks a firm theoretical foundation. This work addresses this. The original EMD algorithm is slightly modified, in a way that facilitates its analysis. We prove three theorems that give conditions for the(More)
Current DBS therapy delivers a train of electrical pulses at set stimulation parameters. This open-loop design is effective for movement disorders, but therapy may be further optimized by a closed loop design. The technology to record biosignals has outpaced our understanding of their relationship to the clinical state of the whole person. Neuronal(More)
— In robot-assisted surgery, surgical tools interact with tissues that have nonlinear mechanical properties. For situations where a pre-specified trajectory of tool positions (or applied forces) is desired, there are many controller designs that might be used. Four candidates are comparatively evaluated here, via computer simulation involving a nonlinear(More)
large number of Brain-Computer Interfaces (BCIs) are currently under development , or being proposed, for both medical and non-medical applications. These applications include advertising, market surveys, focus groups and gaming. For example, in 2008, the Nielsen Company acquired Neurofocus, for the development of neural engineering technologies aimed at(More)
