Handheld Controller Handle Sensors for Finger Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional handheld controllers in virtual reality systems fail to capture detailed hand movements, including individual finger movements and gestures, due to lack of advanced button configurations.
Innovation Solution
Incorporation of detection sensors, such as pressure, capacitive touch, and proximity sensors on the handle of the controller to detect the presence and movement of fingers and the hand, allowing for more nuanced hand interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional button configurations are used on handheld controllers, then the device structure remains simple, but detailed hand movements including individual finger movements and gestures cannot be detected
Solution Approach 1:
The patent replaces traditional mechanical button configurations with optical detection sensors (such as optical sensors, cameras, or proximity sensors) that can detect detailed hand movements, finger positions, and gestures without requiring physical contact. This substitution enables precise measurement of hand movements while maintaining a simpler mechanical structure without multiple physical buttons for each finger movement.
2Adaptability or versatility
If traditional button configurations are used on handheld controllers, then the manufacturing process remains simple, but the ability to capture individual finger movements and gestures is lost
Solution Approach 1:
The patent implements a multi-functional detection sensor system that can simultaneously detect multiple types of hand interactions including individual finger movements, hand gestures, grip strength, and spatial position. This universal detection capability replaces the need for separate physical buttons or sensors for each type of interaction, thereby improving adaptability while actually simplifying the manufacturing process by reducing the number of separate components needed.
3Loss of information
If detection sensors are added to the controller handle, then detailed hand movements can be detected, but the device complexity increases
Solution Approach 1:
The patent combines multiple detection functions into a single integrated sensor system or a small array of multi-functional sensors mounted on the controller handle. By merging detection capabilities (such as combining proximity detection, gesture recognition, and grip strength measurement into one or a few sensor units), the system captures comprehensive hand movement information while minimizing the increase in device complexity compared to using separate sensors for each function.

Implementation Method 1
The detection sensor can be a pressure sensor, a capacitive touch sensor, or a proximity sensor to detect the touch or spatial location of the user's fingers relative to the handle.
Implementation Method 2
The detection sensor can be a pressure sensor, a capacitive touch sensor, or a proximity sensor to detect the touch or spatial location of the user's fingers relative to the handle.
Data Source
AI summary
A handheld controller configured to be held by a user's hand. The handheld controller comprising a main body, and a handle extending from the main body, wherein the handle has a palm side and a finger side. A control button is positioned on the main body or handle, and a detection sensor is on the handle. The detection sensor is positioned to detect the presence of the finger or palm of a user's hand engaging the handle. The detection sensor can be a capacitive touch sensor, a proximity sensor or other detection sensor operative to detect the touch or spatial presence of the user's hand or fingers.
