Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content display technologies lack intuitive and simple methods for users to control the content displayed on flexible or deformable devices, such as mobile terminals and navigation systems, which limits user interaction and information access.
Innovation Solution
A method and apparatus that detect user input deformation of the device's housing to perform geometric transformations, such as changing the scale or rotation of content, allowing different content to be displayed based on the deformation location, enabling users to control the display of content through physical manipulation of the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button or touchscreen controls are used, then device structure is simple, but user interaction is not intuitive and information access is limited
Solution Approach 1:
The patent applies the dynamics principle by making the housing deformable rather than rigid. The housing can dynamically change its shape in response to user manipulation, enabling intuitive interaction without adding complex control components. The deformable housing itself becomes the control interface, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The deformable housing serves dual purposes: it is both the structural enclosure and the user interface. By deforming the housing, users directly control content display without needing separate control mechanisms. This self-service approach allows the housing to provide both protection and interaction functionality, improving ease of operation without increasing overall device complexity.
2Loss of information
If uniform scaling of content is applied, then content coherence is maintained, but additional information cannot be displayed
Solution Approach 1:
The patent applies local quality by implementing non-uniform scaling where different portions of the content are scaled at different rates. The first portion of content is scaled at a first rate while the second portion is scaled at a second rate, allowing selective expansion of information-rich areas while maintaining coherence in other areas. This resolves the contradiction by allowing information access without completely sacrificing content coherence.
Solution Approach 2:
The content is segmented into multiple portions that can be independently scaled. By dividing the content into a first portion and a second portion, the system can apply different scaling operations to different segments, enabling display of additional information while maintaining the overall structure and coherence of the original content through selective scaling of segments.
3Adaptability or versatility
If the display area is fixed, then device structure is simple, but content flexibility and user control are limited
Solution Approach 1:
The patent makes the display area dynamic by coupling it to the deformable housing. As the housing deforms, the display area dynamically adjusts its shape and size to match the housing contours. This dynamic adaptation provides content display flexibility without requiring complex independent display control systems, as the display structure passively follows the housing deformation.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides structural protection, enables user interaction through deformation, and defines the display area boundaries. This multi-functionality allows the display area to be flexible and adaptable without adding separate control mechanisms, as the housing itself orchestrates all three functions.

AI summary
A method, apparatus and computer program comprises: displaying, first content (41) on a display (15); detecting a user input wherein the user input comprises deforming (e.g. folding or bending) at least a portion of a housing (25) of an apparatus (1); and in response to detecting the user input, performing a geometric transformation on the content (51) such that after the geometric transformation second content (43), different to the first content (41) is displayed on the display (15); wherein the location of the deforming within the housing of the apparatus (45) determines a location within the content for performing the geometric transformation.
