Information Display Device Fine Manipulation Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information display devices face difficulties in performing fine manipulations accurately on objects displayed on screens, as existing techniques struggle to precisely control the rotation or state changes of objects based on user input.
Innovation Solution
An information display device with a processor that displays changeable objects and a manipulator with markers, allowing users to input manipulations by setting a starting and destination location, with the processor performing two modes of processing: a normal mode and a fine mode, where the processor changes the object's state more finely in response to input manipulations when the manipulator is shown, using vectors defined by distance and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional finger movement detection is used to change object display state, then the operation is simple and fast, but the manipulation precision is insufficient for fine adjustments
Solution Approach 1:
The system dynamically switches between two processing modes: first type processing for normal operations and second type processing for fine manipulations. The processor determines which mode to apply based on the operation context, allowing users to achieve both fast normal operations and precise fine adjustments without a permanently complex interface
Solution Approach 2:
The system changes the processing parameters by applying different scaling factors to the finger movement vector. In first type processing, a standard scaling factor is used for normal speed. In second type processing, a smaller scaling factor is applied to achieve finer control and more precise manipulation of the object's display state
2Measurement precision
If a manipulator with markers is displayed to enable fine manipulation, then the manipulation precision improves, but the display area for the object decreases
Solution Approach 1:
The manipulator is dynamically displayed or hidden based on the current operation mode. When second type processing (fine manipulation) is needed, the manipulator with markers is displayed to provide precise control references. When first type processing (normal operation) is sufficient, the manipulator is hidden to maximize the object display area
3Adaptability or versatility
If the processor applies uniform processing to all input manipulations, then the system is simple to implement, but it cannot provide both normal speed operations and fine adjustments
Solution Approach 1:
The processor implements dynamic mode switching between first type processing and second type processing. The system determines which processing type to apply based on the operation context, enabling adaptability for both normal-speed operations and fine adjustments without requiring a permanently complex processing logic
Solution Approach 2:
The system changes processing parameters by applying different scaling factors to the same input manipulation. First type processing uses a standard scaling factor for normal operations, while second type processing uses a smaller scaling factor for fine adjustments, allowing the same input to produce different levels of object state change

AI summary
An information display device includes an input interface that accepts an input manipulation including setting a starting location and a destination, and a processor that displays in a display area, an object and a manipulator for use to enter an instruction to change the display state of the object. The processor changes the display state in accordance with a vector to be defined by the distance and direction from the starting location to the destination. The processor performs a first type of processing in response to the input manipulation done on a region other than a region of the manipulator, and a second type of processing of changing the display state in response to the input manipulation done on the region of the manipulator. In the second type of processing, the display state of the object can be changed more finely than in the first type of processing.
