WRITING INSTRUMENT, SYSTEM AND METHOD FOR TRANSPARENT MONITORING AND ANALYSIS OF WRITING

The present invention relates to a writing instrument (1) comprising: - a writing element (20) comprises a writing end (21) configured for depositing a writing material on a support; - a plurality of sensors comprising at least: - a force sensor (30) configured to measure a force applied to said writing element (20), and - a movement sensor (43) configured to measure movement of the instrument (1) in a three- dimensional space; - a communication unit (44) configured to exchange data with a remote device via a wireless communication channel; - a control unit (41) connected to the plurality of sensors and to the communication unit (44) configured to control said plurality of sensors and said communication unit (44) in order to transmit to the remote device the measures provided of the plurality of sensors in presence of a connection between the communication unit (44) and the remote device, - a memory unit (42) connected to the control unit (41) and configured to store one or more measures of said plurality of sensors, and - a hollow casing (10) configured to contain at least partially said writing element (20), so as to leave the writing end (21) of the writing element (20) exposed through a first end (11) of the casing (10), and to contain completely said plurality of sensors, the control unit (41), the memory unit (42) and the communication unit (44). Advantageously, the control unit is further configured: - to detect a condition of lack of connection between the communication unit (44) and the remote device, - in such a condition of lack of connection, to detect writing measures corresponding to movement measures having amplitude of movement greater than a threshold, and - to store the writing measures if, within a predetermined period of time, the control unit detects a number of writing measures greater than a predetermined number. La présente invention porte sur un instrument d'écriture (1) comprenant : - un élément d'écriture (20) qui comprend une extrémité d'écriture (21) conçue pour déposer un matériau d'écriture sur un support ; - une pluralité de capteurs comprenant au moins : - un capteur de force (30) configuré pour mesurer une force appliquée audit élément d'écriture (20), et - un capteur de mouvement (43) configuré pour mesurer le mouvement de l'instrument (1) dans un espace tridimensionnel ; - une unité de communication (44) configurée pour échanger des données avec un dispositif distant par l'intermédiaire d'un canal de communication sans f
