Biofeedback Game Controller Modulating Inputs via Physiological Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biofeedback-modulated video games require multiple training sessions and regular practice to maintain physiological self-regulation skills, with limited adherence to home-based training, limiting their utility.
Innovation Solution
A new type of video game controller using wireless motion-sensing technologies with accelerometers, gyroscopes, and infrared LED tracking cameras modulates player inputs based on physiological signals, such as EEG and heart rate, to encourage self-regulation of physiological activities by dynamically adjusting the controller's motion and position sensing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biofeedback-modulated video games require multiple training sessions and regular practice to maintain physiological self-regulation skills, then the training effectiveness is improved, but the adherence to home-based training deteriorates
Solution Approach 1:
The system dynamically modulates game parameters in real-time based on physiological feedback, creating an adaptive training experience that adjusts to the player's current state without requiring rigid structured sessions
Solution Approach 2:
The system implements continuous physiological feedback loops where game parameters are automatically adjusted based on real-time measurement of physiological signals, enabling self-regulated practice without external supervision
2Adaptability or versatility
If motion-sensing input devices are used to modulate player inputs based on physiological signals, then player engagement is enhanced, but device complexity increases
Solution Approach 1:
The motion-sensing controller serves multiple functions: it detects player movements for game control, senses physiological signals for feedback, and integrates both data streams to modulate game parameters, eliminating the need for separate dedicated devices
Solution Approach 2:
The system combines motion-sensing capabilities with physiological signal detection into a single integrated controller unit, merging previously separate functions into one device

AI summary
New types of controllers allow players to make inputs to a video game or simulation by moving the entire controller itself. This capability is typically accomplished using a wireless input device having accelerometers, gyroscopes, and an infrared LED tracking camera. The present invention exploits these wireless motion-sensing technologies to modulate the player's movement inputs to the videogame based upon physiological signals. Such biofeedback-modulated video games train valuable mental skills beyond eye-hand coordination. These psychophysiological training technologies enhance personal improvement, not just the diversion, of the user.
