AI Technical Summary

Technical Problem

Existing information input systems using 6-axis sensors for detecting acceleration and angular velocity in three axes suffer from reduced accuracy compared to 9-axis sensors that include magnetism detection, while 9-axis sensors are more expensive, leading to higher costs.

Method used

An information input system that utilizes a 6-axis sensor to acquire first and second observed values, such as acceleration and angular velocity, and employs an estimation model to derive an estimated value by considering both types of observations, thereby enhancing accuracy without increasing costs.

Benefits of technology

The system accurately acquires user input information with high precision while maintaining cost-effectiveness by leveraging a 6-axis sensor and an estimation model that combines multiple observations to minimize errors.

Abstract

To acquire input information input by a user with high accuracy while suppressing increase in cost.SOLUTION: An information input system 1 includes: an acquisition unit 12 which acquires, from a motion sensor 208, an observation value regarding a motion of a writing instrument 20; an estimation unit 15 which estimates, on the basis of the observation value, an estimation value Ep of the state of the writing instrument 20; a recognition unit 16 which recognizes a trajectory T1 of the writing instrument 20, on the basis of the estimation value Ep; and an output unit 19 which outputs, on a display unit 13, information indicated by the trajectory T1 of the writing instrument 20, as writing information D4 written by the writing instrument 20. The acquisition unit 12 acquires, as observation values, a first observation value Ma and a second observation value Mg different in a kind. The estimation unit 15 derives the estimation value Ep, through an estimation model M which receives the first observation value Ma and the second observation value Mg as pieces of input, using the first observation value Ma and the second observation value Mg as explanatory variables and the estimation value Ep as an objective variable.SELECTED DRAWING: Figure 6
