The aim of this work is to describe and validate a technique for measuring the posture of all the segments of the hand in a non-invasive way. The technique uses digital photographic images to reconstruct 3-D location of markers drawn on the skin. The markers are defined to obtain joint rotation angles with physiological meaning. Different experiments have been developed in order to analyze the accuracy and repeatability of the angle measurements. Although the placement of markers does not require any special care, the errors due to their location are lower than deg in all cases, thus assuring the repeatability of the technique.
