Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling electronic devices using remote controllers are inconvenient as they require users to press multiple buttons to select content, making it difficult to navigate and interact with information displayed on screens.
Innovation Solution
A remote controller equipped with sensors such as accelerometers, gyro sensors, and geomagnetic sensors that allow for intuitive control by mapping motion information to a pointer on the screen, enabling absolute pointing and gesture recognition for selecting objects without the need for multiple button presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button-based remote control is used, then device control functionality is achieved, but user convenience and operation speed deteriorate due to multiple button presses required
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a motion-based control system using sensors (accelerometer, gyro sensor, geomagnetic sensor) to detect remote controller movements. This substitution eliminates the need for multiple button presses by mapping physical motion directly to pointer position and content selection, significantly improving user convenience and reducing operation time
Solution Approach 2:
The patent introduces a pointer as an intermediary element between the remote controller and the content selection process. The pointer translates sensor-detected motion into screen position, serving as a mediator that connects physical movement to digital interaction, thereby reducing the complexity of direct button manipulation
2Ease of operation
If motion sensors are added to enable intuitive control, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent makes the remote controller multi-functional by integrating multiple sensor types (accelerometer, gyro sensor, geomagnetic sensor) into a single device. These sensors collectively provide comprehensive motion detection capabilities, enabling the remote to function both as a traditional control device and as a motion-sensing pointing device, thereby justifying the added complexity through enhanced functionality
Solution Approach 2:
The patent combines multiple sensor functions and control modes into a unified remote controller system. By merging motion detection, pointer control, and content selection into a single integrated system, the patent reduces overall system complexity compared to having separate devices for each function

AI summary
A remote controller includes a communicator configured to perform communication with a display apparatus which provides a user interface screen, a sensor configured to sense a movement of the remote controller, and a controller configured to control so that, when a preset event occurs, motion information of the remote controller as sensed at the sensor is mapped with a reference point of a pointer provided on the user interface screen.
