Eye-gesture-based Multi-Context Interaction

Eye gestures have been acknowledged as a crucial real-time input channel for human-computer interaction, especially for people with disabilities who lack fine motor skills. However, existing eye-gesture-based interactions mainly rely on gaze duration, which can cause visual fatigue and is not user-friendly for those with disabilities. To address these issues, we propose acceptable interactive paths based on eye gestures in multiple contexts, such as reading and selection, to assist impaired individuals in interacting efficiently and naturally in their daily work. In the selection context, cursor movement is accomplished by fixation position, while single and double clicks of the left mouse button are executed through blink frequency. In the reading context, page scrolling is controlled by the vertical coordinates of the fixation position. In experiments, we set up reading and selection contexts to evaluate and compare the constructed interaction paths with the existing system. The experimental results demonstrate that the interaction paths proposed in this paper are efficient and natural.
