Various anomalies of the flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) muscles of the little finger have been reported in the literature. These include many variations of the FDS and FDP, such as absence of the little finger FDS tendon, aplasia of the FDP to the little finger, an accessory FDS to the little finger, doubling of the tendon, attachments to other superfi...

In this article we present a new isometric input device for multi-fingered grasping in virtual environments. The device was designed to simultaneously assess forces applied by the thumb, index, and middle finger. A mathematical model of grasping, adopted from the analysis of multi-fingered robot hands, was applied to achieve multi-fingered interaction with virtual objects. We used the concept o...

Manipulation of complex simulated entities like cloth in graphical applications can be non-intuitive and awkward for the user due to the high number of degrees of freedom in their motions. In robotics, direct control of a robotic manipulator for a highlydexterous task is similarly tedious because multiple joints have to be controlled simultaneously, in close coordination and often in varying ve...

We describe an unusual case of a 12-year-old boy who presented with a loss of motion in the ring finger caused by 2 separate periosteal chondromas involving the proximal and middle phalanges. Range of motion improved and recurrence did not occur at the 5-year follow-up after marginal excision of both lesions.

The exploitation of finger and hand tracking technology based on infrared light, such as FTIR, Diffused Illumination (DI) or Diffused Surface Illumination (DSI) has enabled the construction of large-scale, low-cost, interactive multi-touch surfaces. In this context, access and security problems arise if larger teams operate theses surfaces with different access rights. The team members might ha...

Visual and somatosensory signals participate together in providing an estimate of the hand's spatial location. While the ability of subjects to identify the spatial location of their hand based on visual and proprioceptive signals has previously been characterized, relatively few studies have examined in detail the spatial structure of the proprioceptive map of the arm. Here, we reconstructed a...

An input (e.g., airplane takeoff sound) to a sensory modality can suppress the percept of another input (e.g., talking voices of neighbors) of the same modality. This perceptual suppression effect is evidence that neural responses to different inputs closely interact with each other in the brain. While recent studies suggest that close interactions also occur across sensory modalities, crossmod...

BACKGROUND People with diabetes mellitus are instructed to clean their skin prior to self-monitoring of blood glucose to remove any dirt or food residue that might affect the reading. Alcohol-based hand sanitizers have become popular when soap and water are not available. The aim of this study was to determine whether a hand sanitizer is compatible with glucose meter testing and effective for t...

We investigated whether gaze direction modified the pattern of finger movement activation in human cerebral cortex using functional magnetic resonance imaging (MRI). Participants performed a sequential finger-tapping task or made no finger movements while maintaining gaze in the direction of the moving hand (aligned conditions) or away from the location of the moving hand. Functional MR signals...
