Rotation-Based Icon Selection for Touch Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices with touch panels and displays require multiple touch operations and screen movements for selecting albums and moving images, leading to user fatigue and inefficiency.
Innovation Solution
An information processing apparatus that uses a motion sensor to detect the rotation of the device, allowing icons to be selected based on the device's angle, with the controller determining the appropriate icon to display and interact with based on the rotation angle, thereby simplifying the selection process by integrating touch panel inputs with rotational movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple touch operations and screen movements are used for selecting albums and moving images, then the selection functionality is achieved, but user fatigue increases and operation efficiency decreases
Solution Approach 1:
The patent introduces a third dimension (device rotation angle) to the traditional two-dimensional touch interface. By detecting the rotation angle of the device, the system maps spatial orientation to interface state changes, allowing users to select between album view and moving image view by simply rotating the device rather than performing multiple touch operations to navigate through screens or menus.
2Adaptability or versatility
If the interface requires multiple screen movements for selection, then all options can be accessed, but the interface complexity and operation steps increase
Solution Approach 1:
The device rotation detection mechanism serves multiple functions: it detects user intent to switch between different content types (albums vs. moving images), it automatically adjusts the display interface accordingly, and it provides a unified interaction paradigm that works regardless of the current screen state. This single multi-functional mechanism replaces what would otherwise require multiple specialized controls and navigation steps.
