Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively integrate eye gaze direction into haptic feedback, limiting the immersive experience in human-computer interactions by not synchronizing haptic effects with the user's visual focus.
Innovation Solution
A system comprising a detector to determine eye gaze direction, a processor to generate haptic effects based on this direction, and a haptic output device to provide tailored haptic sensations, enhancing the user's experience by matching haptic feedback with their visual attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If eye gaze detection is integrated into haptic feedback systems, then the immersive experience and realism are improved, but the device complexity increases
Solution Approach 1:
The patent combines eye gaze detection functionality with haptic feedback delivery by integrating a detector (camera) and processor that work together to synchronize visual attention tracking with tactile output. This merging of detection and feedback systems creates a unified immersive experience while managing complexity through integrated architecture.
Solution Approach 2:
The system uses a multi-functional processor that handles both eye gaze detection processing and haptic effect generation based on the detected gaze direction. This universal processing approach allows one component to serve multiple functions, improving adaptability without proportionally increasing overall device complexity.
2Reliability
If haptic effects are synchronized with eye gaze direction, then user engagement and realism are enhanced, but the processing requirements and system complexity increase
Solution Approach 1:
The system implements a feedback loop where the detector continuously monitors eye gaze direction and the processor adjusts haptic effects in real-time based on this feedback. This closed-loop approach ensures accurate synchronization between visual focus and tactile feedback, improving reliability through continuous adaptation.
Solution Approach 2:
The processor pre-processes eye gaze data to determine direction and selects appropriate haptic effects before delivering tactile output. This preliminary processing approach ensures accurate synchronization by preparing the haptic response in advance based on detected gaze direction, reducing latency and improving timing precision.

AI summary
Systems, electronic devices, and methods provide haptic sensations as a function of eye gaze. A system may include a detector configured to determine a direction of an eye gaze of a user of the system, a processor configured to generate signal representative of a haptic effect based on the direction of the eye gaze, and a haptic output device configured to receive the signal from the processor and output the haptic effect to the user. A method for providing a haptic effect to a user of a system may include determining a direction of an eye gaze of the user of the system, generating a haptic effect based on the direction of the eye gaze, and outputting the haptic effect to the user.
