Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face limitations in recognizing hand-drawn objects due to slow recognition speed and complex processing, making it inconvenient for users to input various diagrams or graphs through touch input.
Innovation Solution
An electronic device and method that allows for rapid recognition and generation of various objects based on a user's touch input pattern, enabling the creation of complex shapes by determining the trajectory of touch inputs and modifying or generating objects accordingly, including basic and complex forms like charts and graphs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional hand-drawn object recognition is used, then various diagrams or graphs can be input through touch input, but the recognition speed is slow and the processing process is complex
Solution Approach 1:
The patent segments the object recognition process into distinct phases: trajectory detection, vertex identification, shape classification, and object generation. By dividing the complex processing into modular segments with specific algorithms for each phase, the system achieves faster processing while reducing overall complexity
Solution Approach 2:
The patent changes key parameters such as touch input sensitivity thresholds, trajectory sampling rates, and shape matching criteria to optimize recognition speed. By adjusting these parameters dynamically based on input characteristics, the system maintains high-speed recognition without sacrificing accuracy
2Adaptability or versatility
If complex shapes are generated from scratch, then various objects can be created, but the operation becomes time-consuming and complex
Solution Approach 1:
The patent pre-defines a library of basic geometric shapes and object templates that can be rapidly instantiated. By preparing these shapes in advance with predetermined properties and relationships, the system can generate complex objects by combining pre-defined elements rather than creating them from scratch, significantly reducing generation time
Solution Approach 2:
The patent implements a hierarchical object structure where complex objects are composed of nested simpler shapes and elements. Basic geometric shapes serve as building blocks that can be nested within each other to form increasingly complex structures, allowing versatile object creation through systematic composition rather than manual construction

AI summary
An electronic device is provided. The electronic device includes a touch screen that receives the touch input from a user and displays an object and a control unit that determines an object having a shape corresponding to a trajectory of the touch input, determines whether a previously generated object is present in a position in which the touch input is received, modifies the previously generated object based on the determined object when the previously generated object is present, and generates the determined object when the previously generated object is absent.
