Foot Gesture Control for Immersive Game Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control methods for electronic devices and games primarily rely on hand-operated controllers, which do not incorporate foot actions, limiting immersive experiences, especially in applications like Virtual Reality games and sport video games where foot gestures could provide more natural and responsive control solutions.
Innovation Solution
A foot-gesture-based control system that utilizes sensors to detect foot tilt angles and touch states, allowing users to control game characters' movements in four directions by changing foot tilt states, enabling natural and immersive control experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand-operated controllers are used for control, then control precision is maintained, but user immersion and natural interaction are reduced
Solution Approach 1:
The patent replaces hand-operated mechanical controllers with a foot gesture recognition system that uses sensors (accelerometers, gyroscopes, pressure sensors) to detect foot movements. This substitution enables natural foot-based interaction while maintaining control precision through sophisticated gesture recognition algorithms that process sensor data to determine user intent.
Solution Approach 2:
The system introduces foot gesture recognition technology as an intermediary between the user and the game character control. Sensors embedded in footwear or the ground act as mediators that capture foot movement data and translate it into control commands, enabling natural foot-based interaction without direct hand controller involvement.
2Ease of operation
If foot gestures are used for control, then user immersion is enhanced, but control detection accuracy becomes more difficult
Solution Approach 1:
The patent segments foot gesture detection into multiple independent sensor measurements (acceleration, rotation, pressure) that are processed separately and then integrated. This segmentation allows the system to accurately detect complex foot gestures by analyzing individual sensor inputs and combining them to determine user intent, thereby improving detection accuracy while maintaining immersive foot-based control.
Solution Approach 2:
The system implements feedback mechanisms where sensor data from foot movements is continuously monitored and processed to provide real-time control responses. The feedback loop refines gesture recognition by comparing detected patterns against known gesture profiles, improving detection accuracy over time while maintaining natural immersive interaction.

AI summary
Foot-gesture-based movement control method for a game character includes a four-way movement start control process, including: determining the game character being in a non-moving state; obtaining foot tilt angles and tilt states of left and right feet of a user; determining a tilt state change of each foot of the user; and generating movement start controls in first, second, third, and fourth directions for the game character, respectively when the right foot is detected changing from a leveled state to a positively tilted state and changing from a leveled state to a negatively tilted state, the left foot is detected changing from a leveled state to a positively tilted state and changing from a leveled state to a negatively tilted state.
