Haptic Interaction-Based VR Simulator for Tactical Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tactical training platforms provide insufficiently realistic visual and sensory experiences, leading to doubts about the effectiveness of training due to discrepancies between simulated and actual equipment, and require a large number of sensors on the haptic interaction glove to track hand position, direction, and shape.
Innovation Solution
A virtual reality simulator that uses a minimal number of sensors to determine the position, direction, and shape of a virtual hand synchronized with a haptic interaction glove, delivering a more realistic haptic stimulus by designating a haptic stimulus application region based on contact with virtual objects within a virtual tactical training environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large number of sensors are used on the haptic interaction glove to track hand position, direction, and shape, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the hand tracking function into three independent sensor modules: acceleration sensing for position, gyroscope sensing for direction, and distance sensing for shape. Each sensor type uses a minimal number of units strategically positioned to capture specific aspects of hand movement, avoiding the need for a dense array of sensors while maintaining comprehensive tracking capability
Solution Approach 2:
The patent makes each sensor serve multiple functions: the acceleration sensor not only tracks position but also contributes to determining hand orientation when combined with gyroscope data; the distance sensor between fingers serves both shape determination and contact detection purposes. This multi-functionality reduces the total sensor count while preserving measurement precision
2Device complexity
If existing tactical training platforms use simple visual and sensory UIs, then device complexity is reduced, but realism of haptic stimulus deteriorates
Solution Approach 1:
The patent applies local quality by providing differentiated haptic feedback to specific regions of the hand based on contact detection. When a virtual object is contacted, the system identifies which finger or hand region is involved and applies haptic stimulus locally to that specific area, creating realistic tactile sensations without requiring complex global UI systems
Solution Approach 2:
The patent implements a closed-loop feedback system where hand position, direction, and shape are continuously tracked, contact with virtual objects is detected in real-time, and haptic stimuli are dynamically adjusted based on contact state. This feedback mechanism enhances training realism by providing immediate tactile response to user actions, compensating for the simplicity of the overall UI architecture

AI summary
The present disclosure proposes a haptic interaction-based virtual reality simulator and a method for operating the same, wherein a virtual tactical training environment is implemented through a virtual display device (for example, HMD), and a haptic stimulus is delivered on the basis of the position, direction, and shape of a virtual hand displayed while being synchronized with a haptic interaction glove worn by a tactical trainee inside the virtual tactical training environment, thereby improving the effect of the tactical training.
