Abstract

Large-screen human-computer interaction technology is reflected in all aspects of daily life. The dynamic gesture tracking algorithm commonly used in recent large-screen interactive technologies demonstrates compelling results but suffers from accuracy and real-time problems. This paper systematically addresses these issues by a switching federated filter method that combines particle filtering and Mean Shifting algorithms based on a 3D sensor. Compared with several algorithms, the results show that the one-hand and two-hand large-screen gesture tracking based on the switched federated filtering algorithm work well, and there is no tracking failure and loss of target. Therefore, the switching federated tracking positioning algorithm can be well applied to the design of human-computer interaction system and provide new ideas for future human-computer interaction.

Summary

Introduction

The definition of human-computer interaction technology is based on a certain software program through the corresponding input and output devices, and the organic combination of computer and human operations is employed to realize the related technology of interactive communication [1– 17]. The current large-screen human-computer interaction technology is mainly divided into the following categories: (1) infrared frame touch interaction; (2) capacitive touch-based electronic screen touch interaction; (3) speech recognition interaction; (4) computer vision interaction. These types of technologies have their own advantages and disadvantages in terms of cost, accuracy, interactivity, etc. This paper proposes a large-screen interactive imaging system with switching federated filter method based on 3D sensor and validates the tracking results with the independently developed gesture position tracking platform.
