Touch Panel Display Interface Positioning via Device Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large touch panel displays on portable electronic devices make it difficult to operate input keys due to the increased range required for finger movement, especially when using a QWERTY keyboard, which can be cumbersome for one-handed operation.
Innovation Solution
An information processing apparatus equipped with a tilt detector, touch panel display, and controller that moves the display position of the operator interface based on the device's posture, allowing the interface to be easily accessed and operated by tilting the device, thereby reducing the size and reconfiguring the input keys for easier use with one hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display size of objects on the touch panel is increased, then the visual clarity and visibility are improved, but the range required for finger movement to operate input keys increases, making operation more difficult
Solution Approach 1:
The operator interface dynamically changes its display position and configuration based on the detected apparatus posture. When the device is tilted, the controller moves the operator interface to a position that is easier to access with the user's finger in the tilted orientation, making the system adaptive rather than static
Solution Approach 2:
The display position of the operator interface is locally adjusted based on the global apparatus posture. The interface is moved to specific regions of the display (e.g., lower portion when tilted forward, side portions when tilted sideways) to optimize accessibility for the current viewing and operating context
2Adaptability or versatility
If a QWERTY keyboard is displayed on a large touch panel, then the character input capability is improved, but the keyboard occupies a large area requiring two-handed operation, reducing ease of use for one-handed operation
Solution Approach 1:
The operator interface changes its configuration dynamically based on apparatus posture. When the device is tilted to a posture suitable for one-handed operation, the controller reconfigures the interface to display smaller input keys in a compact arrangement that can be operated with one hand, while maintaining full character input capability
Solution Approach 2:
The display parameters of the operator interface (position, size, configuration) are changed based on the detected apparatus posture. The controller adjusts these parameters to optimize the interface for the current operating context, enabling one-handed operation when appropriate

AI summary
The present invention provides a technique for making it easy to operate an operator interface displayed on a touch panel display. A tilt detector detects the position of the apparatus. The touch panel display displays an image of the operator interface and senses touch by a touching object, where a predetermined process is performed in response to a touch action on the operator interface. A controller moves a display position of the image of the operator interface on the touch panel display in a direction in which an information processing apparatus tilts, according to changes in the apparatus posture detected by the tilt detector.
