Dynamic Button Resistance Feedback for Realistic VR Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality systems provide tactile feedback but do not account for the changing state of the target object during user operations, limiting the sense of reality.
Innovation Solution
An information processing apparatus that includes a button with a movable range, detecting the push-in position and providing resistance force feedback based on criteria such as the number of pressing actions, past maximum push-in position, and duration of pressing, to enhance the realism of tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tactile feedback using a vibrator is provided, then basic tactile feedback is achieved, but the sense of reality is insufficient because the state of the target object is not reflected
Solution Approach 1:
The patent applies dynamics by making the resistance force characteristic change dynamically based on the virtual object's state. The resistance force is not fixed but varies according to the number of pressing actions, past maximum push-in position, and duration of pressing, allowing the tactile feedback to adapt and reflect the changing state of the virtual object, thereby improving the sense of reality without requiring complex hardware changes
Solution Approach 2:
The patent changes the parameters of the resistance force based on multiple factors including the number of pressing actions, past maximum push-in position, and duration of pressing. By adjusting these parameters dynamically, the system provides more realistic tactile feedback that reflects the virtual object's state changes while maintaining relatively simple processing
2Reliability
If static resistance force is provided, then device structure is simple, but the changing state of the target object cannot be reflected
Solution Approach 1:
The patent implements feedback by using the detected push-in position information and operation history (number of pressing actions, past maximum push-in position, duration of pressing) to dynamically adjust the resistance force. This feedback mechanism ensures that the tactile feedback accurately reflects the virtual object's state, improving both the sense of reality and the quality of operation feedback

AI summary
An information processing apparatus that is connected to a device having a button that can be pressed within a prescribed movement range, detecting the push-in position when the button is pressed, and being capable of presenting a resistance force against a pressing force of the button and that determines control information indicating the magnitude of the resistance force to be presented, which relates to the push-in position of the button on the basis of a determination standard that includes at least one of the number of pressing actions, past maximum push-in position, and duration of pressing operation of the button of the device.
