Wearable Controller Sensor Auto-Calibration During Gameplay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing controller apparatuses require manual calibration of sensors, which can interfere with user operations and is undesirable, especially when temperature changes necessitate recalibration during gameplay.
Innovation Solution
A controller apparatus with a determination section to assess whether sensors are not touched by the user's fingers, allowing for automatic calibration without user awareness, using a processor to set threshold values and calibrate sensors based on detected values and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calibration process is implemented to ensure sensor accuracy, then sensor measurement precision is improved, but user operation convenience deteriorates due to interruption of gameplay
Solution Approach 1:
The controller performs calibration automatically without user intervention. The determination section autonomously detects whether fingers are touching sensors, and the calibration section autonomously executes calibration when conditions are met, eliminating the need for manual user operations during calibration.
Solution Approach 2:
The system performs calibration in advance or during idle moments when sensors are not being used, rather than waiting for user-triggered calibration requests. By monitoring sensor states continuously, the system can calibrate during natural pauses in gameplay before accuracy degradation becomes noticeable.
2Reliability
If calibration is performed during application execution to maintain sensor accuracy under varying temperatures, then sensor reliability is improved, but user operation convenience deteriorates due to interference with gameplay
Solution Approach 1:
The controller autonomously determines when calibration is needed by monitoring sensor states and environmental conditions, and automatically executes calibration without requiring user awareness or intervention, maintaining reliability without disrupting gameplay.
Solution Approach 2:
The calibration timing and execution are dynamically adjusted based on real-time sensor states and environmental conditions. The system flexibly performs calibration during appropriate moments when sensors are naturally unused, adapting to ongoing gameplay rather than following a fixed schedule.
3Ease of operation
If automatic calibration is implemented to eliminate user intervention, then ease of operation is improved, but device complexity increases due to addition of determination and calibration sections
Solution Approach 1:
The determination section utilizes the existing sensor detection capability already present in the controller, making the sensors serve dual purposes: both for gameplay input detection and for determining calibration readiness. This reduces the need for entirely separate determination hardware.
Solution Approach 2:
The calibration section is integrated into the existing controller processing unit rather than being a separate external device. The determination and calibration functions are merged with the controller's existing microcontroller and sensor processing architecture, minimizing additional hardware complexity.

AI summary
A controller apparatus attached to a hand of a user and having a plurality of sensors, the controller apparatus includes: a determination section configured to determine whether or not each of the sensors meets a predetermined condition specifying that a finger of the user is not touching the sensor; and a calibration section configured to calibrate the sensor found to meet the predetermined condition as a result of the determination.
