Display Device Grip Detection to Block Wearable Controller Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality systems, the user's motion of holding a display device with a wearable controller can be erroneously recognized as an operation on the controller, leading to unintended operations.
Innovation Solution
An information processing device connected to a display device includes a control unit that prevents input reception via the controller when the user holds the device with a hand wearing the controller, using sensors to determine the user's grip and adjust controller functionality accordingly.

1Ease of operation
If a wearable controller is used to convert user hand motion into virtual space motion for controlling HMD or HHD, then the user can perform control operations on the display device, but the user's motion of holding the display device can be erroneously recognized as an operation on the controller, leading to unintended operations
Solution Approach 1:
The system dynamically adjusts controller sensitivity and input recognition thresholds based on detected hand posture and device holding state. When the sensor detects that the user's hand is in a holding posture (with fingers wrapped around the device), the system automatically reduces or disables input recognition to prevent erroneous operations, while maintaining normal operation sensitivity when the hand is not in a holding state.
Solution Approach 2:
The system changes operational parameters (input sensitivity, recognition thresholds, and control responsiveness) based on the detected state of the user's hand. By monitoring finger position and hand posture through sensors, the system adjusts the parameters that govern controller input recognition, effectively distinguishing between intentional control operations and accidental inputs caused by holding the device.
2Speed
If the controller continuously monitors user input to enable precise control operations, then the control responsiveness is improved, but false inputs from holding motions increase unintended operations
Solution Approach 1:
The system implements continuous feedback monitoring of hand posture and device state through sensors. This feedback loop allows the system to real-time distinguish between intentional control inputs and accidental inputs caused by holding motions, dynamically adjusting input recognition to maintain responsiveness while filtering out false signals.
Solution Approach 2:
The system performs preliminary detection of hand posture and holding state before processing controller inputs. By pre-assessing whether the user's hand is in a holding configuration, the system can proactively prevent false inputs from being registered, while still maintaining rapid response to legitimate control operations.

AI summary
An information processing device connected to or integrated into a display device configured to receive an input via a controller includes a control unit configured to control, in a case where a user holds the display device with a user's hand wearing the controller, the display device not to receive the input via the controller, or not to execute any processing upon reception of the input via the controller.
