Abstract
Various techniques for three-dimensional trajectory prediction of a stylus are described. An input device, such as a stylus, includes an integrated Inertial Measurement Unit (IMU) (e.g., 3-axis, 6-axis, 9-axis, . . . ) that generates IMU data that is used to predict a future location of the stylus (e.g., the pen tip) in relation to a surface, such as a display surface. The stylus transmits IMU data to a computing device to perform the trajectory prediction. The IMU data is analyzed (e.g., via a machine learning mechanism, or some other device/component) and a stylus state is determined to be in one of a constant velocity state, a constant acceleration state, a constant angular velocity and velocity state, or a constant angular velocity and acceleration state. A prediction model to perform the trajectory prediction can be selected based on the current state of the stylus.
