Claims20
A writing instrument comprising a body and a removable cap, the body being provided with a writing tip and a position detection device, the position detection device being configured to provide data for determining a position of the body in a 2D space or a 3D space, the position detection device comprising a tip pressure sensor, an inertial measurement unit, and a network of radio antennas configured such that the position of the body in the 2D space or 3D space is tracked by sensor fusion, wherein the network of radio antennas provides radio antenna data of the writing instrument, the radio antenna data being used for radio location of the body, the removable cap configured to protect the writing tip, the removable cap being provided with an auxiliary position detection device, the auxiliary position detection device comprising an auxiliary inertial measurement unit and at least one auxiliary radio antenna.
A method for tracking and positioning a writing instrument in a space, comprising:
- providing a writing instrument including a body, the body being provided with a writing tip and a position detection device, the position detection device being configured to provide data for determining a position of the body in a 2D space or a 3D space, the position detection device comprising a tip pressure sensor, an inertial measurement unit, and a network of radio antennas configured such that the position of the body in the 2D space or 3D space is tracked by sensor fusion, wherein the network of radio antennas provides radio antenna data of the writing instrument, the radio antenna data being used for radio location of the body;
- tracking the position of the body of the writing instrument in the 2D space with the position detection device by collecting radio antenna data, tip pressure sensor data and inertial measurement unit data of the writing instrument by the position detection device and sending the collected data by the position detection device to an electronic smart device;
- processing data provided by the position detection device by sensor fusion;
- collecting radio antenna data of the electronic smart device;
- and
- comparing the collected radio antenna data of the writing instrument to the collected radio antenna data of the electronic smart device to determine radio location of the body.
