Hand-drafted Input Shape Recognition for Seamless Object Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies lack an efficient method for users to seamlessly switch between drawing shapes and selecting objects using hand-drafted inputs, requiring mode switching and complicating the interaction process.
Innovation Solution
A display apparatus and method that recognizes hand-drafted inputs as shapes, determines if they are object selecting shapes, and allows users to select objects by displaying a corresponding display component, enabling selection without mode switching through the use of an enter button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hand-drafted input is used to draw shapes, then users can create geometric figures, but users cannot select objects using the same input method
Solution Approach 1:
The patent enables the hand-drafted input method to serve dual functions: drawing shapes and selecting objects. The shape recognition unit determines whether a hand-drafted input is a shape or an object selection gesture, allowing the same input method to perform multiple operations without requiring mode switching, thereby resolving the contradiction between input versatility and operational simplicity
2Ease of operation
If mode switching is required to select objects, then object selection can be performed, but the interaction process becomes complicated
Solution Approach 1:
The patent merges the shape drawing function and object selection function into a single unified process. By recognizing hand-drafted inputs as either shapes or selection gestures based on predefined criteria, the system eliminates the need for separate modes, allowing users to perform both operations continuously without switching, thus reducing time loss and simplifying interaction
3Measurement precision
If hand-drafted input is recognized as shape only, then shape drawing is accurate, but object selection using hand-drafted input is not enabled
Solution Approach 1:
The patent applies different recognition criteria to different regions or patterns of hand-drafted inputs. The shape recognition unit analyzes specific characteristics of the input (such as enclosed areas, stroke patterns, or positional relationships) to determine whether it represents a shape or an object selection gesture, enabling accurate differentiation while maintaining both functions within the same input method

AI summary
A display apparatus includes circuitry to receive input of a hand drafted input, convert the hand drafted input into a shape, and determine whether the shape is an object selecting shape that is preset to be available for selecting an object displayed in the object selecting shape on a display. In a case that the shape is determined to be the object selecting shape, the circuitry displays, on the display, a display component to be operated for receiving selection of the object. In a case that the display component is operated, the circuitry causes the object to be a selected state.
