This study presents a framework for adding natural interaction (touch, gesture, voice) to existing desktop applications without extensive re-coding. This enhances user experience by integrating multi-modal capabilities seamlessly.
Area of Science:
- Human-Computer Interaction
- Computer Science
- Software Engineering
Background:
- Traditional human-machine interaction relies on mouse and keyboard interfaces.
- Modern input devices enable touch-, gesture-, and voice-based interactions in consumer electronics.
- Integrating natural interaction into existing desktop applications often requires substantial redesign and recoding.
Purpose of the Study:
- To present a novel framework for transparently integrating multi-modal interaction capabilities into existing desktop applications.
- To enable the use of natural interaction modalities in applications without requiring significant re-design or re-coding.
- To classify applications that would most benefit from natural interaction modalities.
Main Methods:
- Development of a software framework to intercept and translate natural interaction inputs.
- Integration of the framework with existing desktop applications.
- Experimental evaluation of the framework's effectiveness and performance.
- Classification of application types based on their suitability for natural interaction.
Main Results:
- The proposed framework successfully adds multi-modal interaction capabilities to existing applications.
- The framework operates transparently, requiring minimal changes to the original application code.
- Experimental observations validated the framework's effectiveness in enhancing user interaction.
- A classification of applications was developed, identifying those that gain the most from natural interaction.
Conclusions:
- The presented framework offers an effective solution for incorporating natural interaction into legacy desktop applications.
- This approach reduces the barrier to adopting multi-modal interfaces in diverse software.
- The findings provide valuable insights for developers seeking to enhance user experience through natural interaction.
