VR Controller Knob and Positioning Module for Precision Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handheld controllers for virtual reality systems lack precision and efficiency due to their traditional gaming handle design, which is not optimized for image creation or business use.
Innovation Solution
A handheld controller with a holding portion, a pivotally connected knob, and a positioning module that allows for wireless transmission of angle and position data to a head-mounted display, enabling precise control of virtual reality systems by rotating the knob and moving the controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional gaming handle design is used for virtual reality controllers, then the device structure is simple and easy to manufacture, but the operation precision and efficiency are insufficient for image creation and business use
Solution Approach 1:
The controller is divided into distinct functional modules: holding portion for basic support, knob for rotational control generating angle data, and positioning module for spatial tracking generating position data. This segmentation allows each component to specialize in specific control tasks, improving overall operation precision while keeping individual components relatively simple
Solution Approach 2:
The controller integrates multiple control modalities into a single device: positional control through the positioning module, rotational control through the knob, and directional control through the holding portion orientation. This multi-functionality enables precise control for both gaming and professional applications like image creation, resolving the contradiction between precision and complexity
2Productivity
If traditional buttons are used for controlling virtual reality actions, then the device structure is simple, but the control efficiency and precision are insufficient
Solution Approach 1:
The controller transitions from static button pressing to dynamic continuous control. The knob provides continuous rotational input for precise angular adjustment, and the positioning module provides continuous spatial position data. This dynamic control enables more efficient and precise manipulation compared to discrete button presses, particularly for tasks requiring fine adjustments
Solution Approach 2:
The controller generates real-time angle data from knob rotation and position data from the positioning module, providing continuous feedback to the virtual reality system. This feedback mechanism allows users to make precise adjustments and immediately see the effect, significantly improving control efficiency for tasks like image creation where precision is critical

AI summary
A handheld controller is suitable for controlling a virtual reality system. The handheld controller has a pointer direction corresponding to the virtual reality system. The handheld controller includes a holding portion, a knob, and a positioning module. The holding portion is suitable to be held by a hand of a user. The knob is pivotally connected to the holding portion on a rotation axis. The rotation axis is coaxial with or parallel to the pointer direction. The positioning module is connected to the holding portion and is configured to provide a position of the holding portion in a three-dimensional space. In addition, a control method is also provided here.
