Biofeedback Game Audio-Visual Control for Heart Rate Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer games often fail to maintain a gamer's heart rate within a target zone, leading to either excessive excitement or ennui, which can detract from the gaming experience.
Innovation Solution
A system that uses biometric feedback from heart rate sensors to dynamically adjust audio and video aspects of the game, such as music, sound effects, lighting, and background images, without altering the game's action or difficulty level, to sustain the heart rate within a target zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the game difficulty level is increased to maintain player engagement, then player excitement is improved, but heart rate may exceed the target zone
Solution Approach 1:
The patent segments the control of heart rate into two independent systems: one controlling game difficulty (action parameters) and another controlling audio-visual feedback (presentation parameters). This allows the difficulty to remain challenging while the audio-visual elements independently regulate heart rate through biofeedback mechanisms.
Solution Approach 2:
The patent implements a closed-loop feedback system where heart rate sensors continuously monitor the player's physiological state, and the system dynamically adjusts audio and visual presentations based on this feedback. This ensures the heart rate remains within the target zone while maintaining game engagement through adaptive presentation rather than adaptive difficulty.
2Ease of operation
If the game music and sound effects are intensified to increase excitement, then player engagement is improved, but heart rate may exceed the target zone
Solution Approach 1:
The patent applies dynamics by making the audio and visual presentations dynamically adjustable based on real-time heart rate feedback. The music tempo, sound effect volume, and visual intensity are continuously modulated to match the player's physiological state, creating an adaptive experience that maintains engagement while regulating heart rate.
Solution Approach 2:
The patent changes physical parameters of the game presentation (audio volume, music tempo, visual brightness) in response to heart rate measurements. By adjusting these parameters dynamically, the system can intensify or calm the presentation to match the player's heart rate, maintaining engagement within safe physiological limits.
3Object-affected harmful factors
If the game action and difficulty are modified to regulate heart rate, then heart rate is maintained within target zone, but the gaming experience is degraded
Solution Approach 1:
The patent extracts the heart rate regulation function from the game action itself and places it in the audio-visual presentation layer. This separation allows the game action to remain unchanged and engaging while the audio-visual elements independently handle the physiological regulation, avoiding any degradation of gaming experience.
Solution Approach 2:
The patent introduces audio and visual presentations as intermediary elements between the game action and the player's physiological state. These intermediaries serve as the mechanism for heart rate regulation, allowing the actual game action to remain intact while the presentation layer mediates the physiological response.

AI summary
A biometric sensor such as a heart rate sensor sends signals representative of a video gamer's physical state, e.g., heart rate, to a computer game system, which can vary aspects of the game to maintain the heart rate of the gamer within limits.
