Remote Controller Power Control and GUI Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controllers require cumbersome operations to display or hide graphical user interfaces, and continuous power supply to sensors when not in use leads to increased power consumption.
Innovation Solution
An input device with an operation unit, sending unit, and power control unit that enables graphical user interface display only when the unit is held and operated, and enters a low power state when placed, using angular velocity and acceleration sensors to detect user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the power supply to the angular velocity sensor or acceleration sensor is stopped when the remote controller is not being held, then power consumption is reduced, but holding detection becomes impossible
Solution Approach 1:
The patent applies dynamics by transitioning the sensor system between different operational states based on real-time detection needs. The sensor operates in a low-power state during periods of no activity and automatically transitions to a high-power detection state when a button operation is detected, ensuring reliable holding detection only when necessary while minimizing overall power consumption.
2Ease of operation
If the graphical user interface is displayed when the remote controller is held to reduce volume, then the user can see controls, but the ease of operation is degraded due to unnecessary GUI display
Solution Approach 1:
The patent applies local quality by differentiating between types of operations and providing appropriate GUI responses for each. When a button operation is detected, the GUI is displayed to allow full control functionality. When only holding operations occur (such as volume adjustment), the GUI remains hidden, providing a cleaner view and simpler operation experience tailored to the specific interaction type.
3Ease of operation
If the button operation triggers GUI display, then the user can access controls, but the user must manually activate and deactivate the GUI which is cumbersome
Solution Approach 1:
The patent applies preliminary action by proactively displaying the GUI when button operations are detected, eliminating the need for users to manually activate it. The system anticipates the user's need for controls and automatically makes the GUI available. Similarly, when the remote controller is placed down and no button operations occur, the system automatically deactivates the GUI, saving the user the effort of manual deactivation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves ease of operation by eliminating the need for manual GUI activation/deactivation and reduces power consumption by selectively powering sensors based on usage.
Implementation Method 1
an angular velocity sensor or an acceleration sensor is often used to detect a user operation
Implementation Method 2
an angular velocity sensor or an acceleration sensor is often used to detect a user operation

AI summary
An input device includes an operation unit, a sending unit, and a power control unit. The operation unit is configured to be held by a user and to be operated in a three-dimensional free space so as to remotely operate an information processing apparatus. The sending unit is configured to send a command that disables display of a graphical user interface of the information processing apparatus when the operation unit is placed, and to send a command that enables display of the graphical user interface of the information processing apparatus when a button of the operation unit is operated. The power control unit is configured to cause the input device to enter a low power consumption state when the operation unit is placed.
