研究目的
To design and evaluate a camera-based human-computer interface using a virtual keyboard assistant for individuals with severe motor impairments, such as those with Amyotrophic Lateral Sclerosis (ALS), to enable computer access and improve quality of life.
研究成果
The virtual keyboard assistant, integrated with a camera mouse system, provides an effective and user-friendly interface for individuals with severe motor impairments. It enables tasks such as internet browsing, social media access, music playback, and text-to-speech functionality. Experimental results show improved accuracy and reduced task completion times after training, indicating its potential to enhance quality of life and computer accessibility. Future work should focus on incorporating EEG-based control for more intuitive interaction.
研究不足
The system relies on camera-based tracking, which may be affected by lighting conditions or occlusions. It is evaluated with a small sample size of 15 subjects, and future work is needed to integrate EEG signals for more advanced control. The virtual keyboard design is non-traditional, which might require adaptation for users familiar with QWERTY layouts.
1:Experimental Design and Method Selection:
The study involves designing a virtual keyboard assistant integrated with a camera mouse system for human-computer interaction. The camera mouse software tracks body movements via a webcam to control the computer cursor. The virtual keyboard is developed in Visual Studio IDE using vb.net with Windows Forms and Microsoft Office Access Database Files.
2:Sample Selection and Data Sources:
15 subjects, including those with and without prior knowledge of HCI interfaces, are selected for evaluation. Tasks include typing, logging into Gmail, adding music to a playlist, searching on Google, and adding helper commands.
3:List of Experimental Equipment and Materials:
A computer with a webcam (specific model not mentioned), Visual Studio IDE, vb.net programming language, Windows Forms, Microsoft Office Access Database Files, and the Camera Mouse software (open-source from the official web page).
4:Experimental Procedures and Operational Workflow:
Subjects use the camera mouse to register a body part (e.g., eye) as the pointing device. They perform predefined tasks using the virtual keyboard, with performance measured in time and accuracy before and after training.
5:Data Analysis Methods:
Data on task completion time and accuracy (based on threshold values) are recorded and analyzed to assess system usability and effectiveness.
