Haptic Feedback Discrimination for Multi-Controller Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face difficulties in distinguishing multiple remote controllers and providing corresponding haptic stimuli, such as vibration, to each controller, resulting in a limited ability to create an immersive and realistic experience for multiple users.
Innovation Solution
An information processing apparatus that acquires pointer information from sensor data, discriminates input devices based on their characteristics, and generates haptic stimulation signals to be output to the correct device when specific conditions are met, allowing for a deeper sense of realism and intuitive haptic interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single haptic output system is used for multiple controllers, then device complexity is reduced, but the ability to provide differentiated haptic feedback to each user deteriorates
Solution Approach 1:
The system segments the haptic feedback capability by assigning different vibration patterns, intensities, and types to different input devices based on their identification. Each controller receives customized haptic feedback through the same physical output mechanism, achieving differentiation without requiring separate hardware systems for each user.
2Speed
If pointer information from multiple input devices is processed without discrimination, then processing speed is improved, but the accuracy of delivering haptic feedback to the correct device deteriorates
Solution Approach 1:
The system performs preliminary discrimination of input devices by analyzing characteristics of pointer information (such as position, movement pattern, or timing) before generating haptic feedback. This preliminary identification step ensures that each haptic output is accurately directed to the corresponding input device while maintaining efficient processing through automated characteristic-based differentiation.
3Ease of operation
If haptic feedback is provided to all input devices uniformly, then ease of operation is improved, but the sense of realism and immersion for each user deteriorates
Solution Approach 1:
The system applies local quality by providing customized haptic feedback characteristics (different vibration patterns, frequencies, or intensities) to each identified input device based on its specific characteristics. This allows the same haptic output mechanism to deliver differentiated feedback that enhances realism and immersion for each user while maintaining ease of operation through automated differentiation.

AI summary
There is provided an information processing apparatus, an information processing method, and a program that enable a predetermined haptic stimulus to be presented to a number of corresponding input devices on the basis of inputs from the input devices and thereby realize an intuitive haptic interface that gives a deeper sense of realism. The information processing apparatus includes: an acquisition unit configured to acquire a plurality of pieces of pointer information on the basis of one or a plurality of pieces of sensor data; a discrimination unit configured to discriminate an input device corresponding to each pointer on the basis of characteristics of the plurality of pieces of pointer information; and a generation unit configured to generate a predetermined haptic stimulation signal to be output to an input device corresponding to a pointer in a case in which a position of the pointer satisfies a predetermined condition.
