Gesture-Controlled Image Display Resolving Screen Space Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable recording and reproducing devices face challenges in providing an intuitive and efficient interface for searching through a large number of images due to limited display space and the need for small input devices, leading to difficulties in operation, especially for unskilled users.
Innovation Solution
A recording and reproducing apparatus that uses a detecting means to recognize gestures of a human body or object, allowing the display to switch and move images accordingly, eliminating the need for physical input devices and enhancing user interaction through intuitive gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If thumbnails are displayed collectively on a narrow display area, then the display area is utilized, but the total number of thumbnails displayed at one time becomes small making file search difficult
Solution Approach 1:
The patent applies three-dimensional arrangement of thumbnails in space rather than traditional two-dimensional flat display. By utilizing depth dimension, the system can display a large number of thumbnails simultaneously within the limited display area, allowing users to browse through many images without scrolling or page switching, thus resolving the contradiction between limited display area and file search efficiency
2Ease of operation
If a cross key or jog dial is mounted for operations, then input functionality is provided, but the case becomes larger correspondingly or the display area becomes narrower
Solution Approach 1:
The patent extracts the input functionality from physical buttons and dials, removing them completely from the device. Instead, it uses a touch panel that integrates input controls directly into the display surface, allowing users to interact with the displayed thumbnails through touch operations. This eliminates the need for separate physical input devices while maintaining full input functionality, thus resolving the contradiction between ease of operation and display area
3Area of stationary object
If a touch panel is mounted to eliminate physical input devices, then display area is increased, but the touch panel can provide only simple input operations reproducing cross key and jog dial functions
Solution Approach 1:
The patent implements dynamic and intuitive touch operations that go beyond static button simulations. Users can directly touch, drag, and manipulate thumbnail images themselves rather than using indirect controls. The touch panel responds to natural gestures like pinching, swiping, and tapping, providing rich and flexible input operations that are more intuitive than reproduced cross key or jog dial functions, thus resolving the contradiction between display area and input operation complexity

AI summary
A recording and reproducing apparatus includes: a recording means for storing a plurality of images in groups; a display means for displaying images stored in the recording means; a detecting means for detecting a part of a human body or an object in a predetermined form; and a display switching means for switching images to be displayed on the display means in accordance with a form of a part of a human body or a form of an object detected by the detecting means.
