This paper proposes a new method for grasping an object positioned in a cluttered workspace. The grasping of an object usually relies on the analysis of its contour in order to determine the contact points for the ngers of the gripper. The planning of the positioning of the real gripper in the workspace at the chosen points is often considered as a separate problem. The method proposed in this ...

1 of 3 DESCRIPTION A previously healthy 82-year-old lady presented with abnormal sensation in her fi ngers which she described as ‘feeling like bananas’. There was an additional history of deteriorating handwriting and a sense of imbalance when walking dating back 6 months. She obtained a score of 26 out of 30 on the mini mental state examination. She had gait ataxia, being unable to perform ta...

This paper presents a glove-free method for tracking hand movements using a set of 3-D models. In this approach, the hand is represented by ve cylindrical models which are t to the third phalangeal segments of the ngers. Six 3-D motion parameters for each model are calculated that correspond to the movement of the ngertips in the image plane. Trajectories of the moving models are then establish...

One hazard of interdisciplinary research is that important results in one fi eld may be unknown or totally ignored in another. To ensure that this does not happen, editors and reviewers have an even more diffi cult job and greater responsibility than usual. Scheffer et al.’s (2009) recent review is a case in point. The authors identify ‘early warning signals’ such as critical slowing down in si...

Capacitive tactile sensors are constructed and installed to the ngers of the HKUST hands for measurement of position, force and direction of principle curvature of contact point. The hardware and software for signal processing are designed such that the contact information is sent to the motion control computer in real time. Experiments in rolling and sliding contact motions are then performed ...

Systemic questioning did not reveal morning stiffness, rash, alopecia, dryness in eyes or mouth, or bloody diarrhea. Only occasional pain in joints of hands and feet were described. Family history was uneventful. In physical examination, vital signs were within normal ranges. Widespread erythema was present on both hands, with a more reticular pattern on the dorsal part of the right forearm. Fi...

In this paper we describe our configurable hotspot framework for ubiquitous interaction. A camera points to a physical space, the user defines interaction areas, and designs gestures by combining hotspots (rectangles) that detect simple 2D motions (left_right, top_bottom, etc.).
