Solution Overview
Problem
Users wearing VR devices face inconvenience due to the inability to visually identify button presses, leading to potential incorrect button activations, which hampers the efficiency and accuracy of interactions with VR systems.
Innovation Solution
A VR control method and apparatus that acquires sensor data from VR wearable devices in three-dimensional space within a set time period, determines the moving trajectory based on this data, and controls VR execution devices to perform corresponding operations, displaying these operations on the VR display, allowing users to visually perceive and adjust their movements for accurate interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users interact with VR devices using button presses on touch handles, then control operations can be performed, but users cannot visually identify button presses leading to incorrect activations
Solution Approach 1:
The system provides visual feedback by displaying the movement trajectory of the VR wearable device on the VR display device. This allows users to see their device movements in real-time, enabling them to verify and adjust their input actions, thereby preventing incorrect button activations while maintaining ease of operation.
Solution Approach 2:
The patent replaces the traditional mechanical button-pressing interaction with a motion-based control system. Instead of relying on tactile button presses that cannot be visually confirmed, the system uses sensor data to detect device movements in three-dimensional space and translates these movements into control instructions, substituting mechanical interaction with visualizable motion tracking.
2Measurement precision
If sensor data is continuously acquired for trajectory determination, then accurate control is achieved, but unnecessary data storage occurs
Solution Approach 1:
The system implements periodic data acquisition by setting a specific time period for acquiring sensor data, bounded by a first time point when a first control instruction is received and a second time point when a second control instruction is received. This periodic approach ensures accurate trajectory determination only when needed, preventing continuous data collection and reducing unnecessary storage.
Solution Approach 2:
The system preliminarily determines the time period for data acquisition based on control instructions before actually collecting sensor data. By establishing the acquisition window in advance based on when control instructions are received, the system prepares to collect data only during relevant intervals, avoiding unnecessary data storage while maintaining trajectory accuracy.

AI summary
The present disclosure relates to a VR control method, device and electronic equipment. The method includes: acquiring sensor data indicative of a movement of a VR wearable device in three-dimensional space within a set time period, and the set time period is determined by a first time point at which a first control instruction is received and a second time point at which a second control instruction is received (101); determining a moving trajectory of the VR wearable device within the set time period based on the sensor data within the set time period (102); and controlling a VR execution device to perform operations corresponding to the moving trajectory and to display operation effects corresponding to the moving trajectory on the VR display device (103). According to the solution provided by the present disclosure, actions of a body can be detected so as to control the operation of the VR execution device, and prevent the user from manually pressing different buttons on the handle to trigger different operation, and thereby ensure that the VR execution device can perform the action that the user really wants, to improve the variety of the VR execution device input modes and facilitate interactions between the user and the VR display device.
