Solution Overview
Problem
Multifunctional image display devices face limitations in controlling applications using gestures, as existing technologies can only sense predefined gestures for a limited range of functions, restricting the versatility of gesture-based control.
Innovation Solution
An image display device equipped with a sensing unit, display unit, collection unit, and controller that can sense and match user input gestures with predefined control gesture information to execute specific events, allowing for optimized gesture control tailored to each application, including text-based and condition-based control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single predefined gesture is used for controlling multiple functions, then the device complexity is reduced, but the adaptability and precision of gesture control for specific applications deteriorates
Solution Approach 1:
The gesture control system is segmented into application-specific gesture sets. Each application defines its own unique gestures through the collection unit, which stores and manages multiple gesture types specific to different applications. This segmentation allows the system to maintain low overall complexity while achieving high adaptability for specific applications.
Solution Approach 2:
The gesture control system dynamically adapts to different applications by selecting and executing gestures specific to the currently running application. The controller dynamically switches between different gesture sets based on the application context, enabling the system to optimize gesture control for each application without requiring a completely different system for each application type.
2Adaptability or versatility
If multiple predefined gestures are supported for different functions, then the adaptability improves, but the difficulty of detecting and measuring specific gestures worsens
Solution Approach 1:
The gesture detection system applies local quality by tailoring gesture recognition parameters to each specific application. Each application defines its own gesture characteristics (such as hand shape, movement trajectory, and duration) that are optimized for that particular application's control needs. This localized approach improves detection accuracy for each application while maintaining overall system adaptability.
Solution Approach 2:
The system incorporates feedback mechanisms where the sensing unit continuously monitors user input and compares it against the predefined gestures for the current application. The controller provides feedback by confirming gesture recognition and executing the corresponding application-specific function, thereby improving the accuracy and reliability of gesture detection for each application.
3Ease of operation
If gesture control is enabled for all applications, then the ease of operation improves, but the loss of information increases due to ambiguous gestures
Solution Approach 1:
The system performs preliminary action by establishing the current application context before accepting gesture input. The collection unit pre-loads and prepares the gesture definitions specific to the currently running application, ensuring that when a gesture is detected, the system immediately has the correct reference framework to interpret it unambiguously. This preliminary setup prevents gesture ambiguity while maintaining ease of operation.
Solution Approach 2:
The collection unit serves as an intermediary between the sensing unit and the controller. It acts as a mediator that manages the mapping between detected gestures and application-specific functions, ensuring that gesture information is accurately transmitted and interpreted in the correct contextual framework. This intermediary layer prevents information loss by maintaining clear gesture-application relationships.

AI summary
The present invention provides an image display device comprising: a sensing unit for sensing an input gesture of a user; a display unit for outputting visual information among the executed data of an application when the application is executed; a collection unit for collecting control gesture information included in the executed data; and a control unit for executing an event of the application which is included in the executed data and corresponds to the control gesture information if the control gesture information and the input gesture sensed by the sensing unit are matching while the application is executed.
