Replicating Input Stroke Speed for Animation Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses struggle with simplifying the process of applying animations to drawing objects, particularly in moving objects along user-drawn strokes with variable speeds, which is cumbersome due to the need for multiple steps and menu interactions, especially on small electronic devices with poor input device operability.
Innovation Solution
An information processing apparatus that records and replicates the movement stroke and speed of an input tool, allowing for seamless switching between drawing and stroke input modes, and selecting behavior types based on partial areas or stroke shapes, enabling intuitive and efficient animation application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a preset speed is used for moving a drawing object along a stroke, then the animation can be applied with simple input, but the user cannot control the moving speed to match their drawing speed
Solution Approach 1:
The system automatically uses the stroke input speed as the object movement speed without requiring separate speed settings. The stroke itself serves dual purposes: defining the movement path and determining the movement speed, eliminating the need for users to manually configure speed parameters.
2Adaptability or versatility
If the preset speed is changed through menu items, then the moving speed can be adjusted, but the user operation becomes bothersome and complex
Solution Approach 1:
The speed control function is extracted from the menu system and integrated directly into the stroke input process. By capturing the temporal characteristics of the stroke input itself, the system eliminates the need for separate speed configuration menus, reducing operational steps while maintaining speed adjustability.
3Adaptability or versatility
If multiple input modes and behavior types are provided, then the system becomes more versatile, but the device complexity increases
Solution Approach 1:
The stroke input mechanism serves multiple functions: it defines the movement path, determines the movement speed, and can trigger different behavior types based on the stroke characteristics. This multi-functionality reduces the need for separate controls for each parameter, simplifying the overall system structure while maintaining versatility.

AI summary
An information processing apparatus is provided which includes an input information recording unit for recording, when a movement stroke for an object is input, information on moving speed and movement stroke of an input tool used for inputting the movement stroke, and an object behavior control unit for moving the object, based on the information on moving speed and movement stroke recorded by the input information recording unit, in such a way that the movement stroke of the input tool and a moving speed at each point in the movement stroke are replicated.
