Sensorimotor predictions and tool use: Hand-held tools attenuate self-touch

Human survival requires quick and accurate movements, both with and without tools. To overcome the sensorimotor delays and noise, the brain uses internal forward models to predict the sensory consequences of an action. Here, we investigated whether these sensory predictions are computed similarly for actions involving hand-held tools and natural hand movements. We hypothesized that the predicti...

A Self-Referenced Hand-Held Range Sensor

Due to its portability and great maneuverability, a handheld range sensor is a flexible solution or complement to efficiently digitize the 3-D shape for a wide variety of objects. This paper firstly presents a review of the existing hand-held technologies. Although the designation encompasses various system configurations, the structured light pattern, if any, and sensor positioning are key ele...

Operating hand-held vibrating tools and prevalence of white fingers.

Hand-transmitted vibration levels (HTVLs) and the prevalence of vibration-induced white finger (VWF) and numbness of the hands were investigated in eight groups of subjects operating various hand-held vibrating tools. The prevalence rates of Raynaud's phenomenon (RP) and numbness of the hands in 1,027 males and 1,301 females not occupationally exposed to vibration were compared to those of the ...

The Performance Leader in Hand-Held Network Tools

Design of a training tool for improving the use of hand-held detectors in humanitarian demining

Purpose The purpose of this paper is to introduce the design of a training tool intended to improve deminers' technique during close-in detection tasks. Design/methodology/approach Following an introduction that highlights the impact of mines and improvised explosive devices (lEDs), and the importance of training for enhancing the safety and the efficiency of the deminers, this paper considers ...
