Game Controller Involuntary Reaction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videogame consoles lack the ability to dynamically adapt game elements to a user's emotional response, relying primarily on voluntary inputs and failing to effectively incorporate involuntary physical reactions for enhanced gameplay experience.
Innovation Solution
Integration of a system that utilizes MEMS accelerometers and gyroscopic sensors in hand-held controllers, combined with camera and microphone inputs, to detect and analyze involuntary user reactions such as sudden movements and facial expressions, allowing the game to adjust its environment and intensity of scares based on the player's emotional response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the game system uses multiple sensors (accelerometers, gyroscopes, camera, microphone) to detect user emotional responses, then the ability to detect involuntary physical reactions is improved, but the device complexity increases
Solution Approach 1:
The game controller is designed to perform multiple functions: it serves as both a voluntary control device and an involuntary reaction detector. The same accelerometer and gyroscope sensors that track controller orientation are also used to detect sudden involuntary movements, eliminating the need for separate dedicated sensors and reducing overall system complexity.
Solution Approach 2:
The patent combines multiple detection modalities (accelerometer data, gyroscope data, camera facial expression analysis, and microphone audio analysis) into a unified emotional response detection system. These diverse data streams are merged and processed together to comprehensively assess user emotional state, improving detection accuracy while leveraging existing components.
2Adaptability or versatility
If the game dynamically adjusts audio-visual output based on user emotional response, then the adaptability of the game is improved, but the processing requirements and system complexity increase
Solution Approach 1:
The game system dynamically adjusts audio-visual output in real-time based on continuously monitored user emotional responses. The scare intensity, audio volume, and visual effects are modified on-the-fly rather than being fixed, allowing the game to adapt to the user's emotional state and maintain optimal engagement levels.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where user involuntary reactions are continuously detected, analyzed, and fed back to adjust game parameters. This feedback loop enables the game to respond to user emotional state in real-time, creating an adaptive experience that evolves based on player response without requiring complex manual intervention.
3Measurement precision
If the system analyzes user reactions within a predetermined period after audio-visual events, then the timing precision for emotional response detection is improved, but the processing time requirements increase
Solution Approach 1:
The system establishes a predetermined analysis period window in advance of detecting and evaluating user reactions. By pre-defining the time window for reaction analysis, the system can efficiently process data within known temporal bounds, reducing unnecessary processing while maintaining accurate timing for emotional response detection.

AI summary
A method of user interaction with an entertainment device comprises generating an audio-visual output for use with audio-visual reproduction equipment, initiating an audio-visual event as part of the generated audio-visual output, receiving input data from one or more game control devices associated with the entertainment device, analysing the received input data to evaluate an involuntary physical response by a user interacting with the or each game control device occurring within a predetermined period associated with the initiation of the audio-visual event, and adjusting subsequently generated audio-visual output responsive to the evaluation of the user's involuntary physical response.
