Mobile Terminal Display Motion-Based Image Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminal apparatuses face difficulties in smoothly viewing and diagnosing diagnostic images due to small display panels and the inability to use multiple display changeover operations simultaneously, making it challenging to navigate between image groups and modalities.
Innovation Solution
A mobile terminal apparatus equipped with an orientation sensor that detects different motion modes to control the display unit, allowing for seamless switching between diagnostic images within and between image groups using linear movement, shaking, and rotational motions, enabling efficient navigation of diagnostic images stored on the device and accessed from a server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a control window is displayed beside the diagnostic image to enable image changeover, then image navigation capability is improved, but the display area for the diagnostic image becomes considerably small making it difficult to view
Solution Approach 1:
The patent extracts the control window from the display area, removing it completely to allow full-screen display of diagnostic images. Image changeover is achieved through motion detection instead of traditional control interfaces, eliminating the need for a separate control window and maximizing the display area for medical images.
Solution Approach 2:
The patent replaces the mechanical control interface (mouse, keyboard, control window) with a motion-based control system using acceleration sensors. Doctors can navigate images by physically moving or shaking the mobile terminal, substituting the need for a control window and traditional input devices.
2Productivity
If multiple display changeover operations are used together for diagnosis, then diagnostic efficiency is improved, but the system cannot support multiple operations simultaneously making diagnosis difficult to perform smoothly
Solution Approach 1:
The patent implements dynamic control where different motion modes (translation, rotation, shaking) trigger different image changeover operations. The system dynamically responds to the type and intensity of motion detected, enabling flexible and intuitive navigation through diagnostic images without complex operation coordination.
Solution Approach 2:
The patent changes the control parameter from button presses or menu selections to physical motion parameters (acceleration, orientation, shaking intensity). This allows multiple operations to be performed smoothly by varying the motion parameters, enabling doctors to navigate between image groups and modalities through natural hand movements.

Function Achieved in This Case
Enables easy viewing and smooth diagnosis by utilizing multiple motion modes to changeover diagnostic images, improving user interaction and reducing the complexity of navigating through multiple image groups and modalities on a mobile terminal.
Implementation Method 1
an orientation sensor for detecting first and second motion modes of the display unit with a difference in movement from one another

AI summary
In a mobile terminal apparatus, a display unit displays a diagnostic image read from an image storage device. The image storage device stores plural image groups, each of which includes plural diagnostic images. Movement of the display unit is detected. Assuming that the display unit is moved in a mode of transverse movement while a first diagnostic image included in a first image group is displayed on the display unit, then changeover is carried out to display a second diagnostic image being included in the first image group and different from the first diagnostic image. Assuming that the display unit is moved in a mode of a single shake different from the mode of transverse movement while the first diagnostic image is displayed on the display unit, then changeover is carried out to display a third diagnostic image being included in an image group different from the first image group.
