Abstract
Official abstract text for this publication.
A method of detecting a point of contact between a tip of an instrument and a writing support, the instrument being one of a pen and an eraser, and the method comprising determining, with the aid of a magnetic object fixed without any degree of freedom on the instrument, the height of a point of the instrument with respect to a bearing face of a tablet. The bearing face constituting the writing support or supporting the writing support. The method further includes: comparing the height determined with a preconfigured contact threshold, and detecting a point of contact between the tip of the instrument and the writing support if the height determined is less than the contact threshold and, in the converse case, detecting no point of contact between the tip of the instrument and the writing support.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for detecting a point of contact between a tip of an instrument and a writing support, the instrument being one of a pen and an eraser, the apparatus comprising: a network of magnetometers able to measure the height of a magnetic object fixed without any degree of freedom on the instrument with respect to a bearing face of a tablet, the bearing face constituting the writing support or supporting the writing support, a computer programmed…
