Haptic Feedback Device Translating Video to Tactile Sensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current haptic technologies are underdeveloped and primarily focused on vision-based interaction, lacking advanced touch-sense feedback systems that could enhance user experience, particularly for visually impaired individuals and those seeking supplementary sensory exploration beyond visual means.
Innovation Solution
A haptic feedback device and method that utilizes video input from multiple image-capture devices to generate haptic cues on a haptic feedback interface, allowing users to experience events or environments through touch, leveraging the higher sensory resolution of the sense of touch to provide enhanced haptic sensations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vision-based interaction technology is used, then visual information is effectively transmitted, but touch-sense feedback and sensory resolution are underutilized
Solution Approach 1:
The system segments video information into distinct tactile representations by mapping different visual elements (objects, movements, scenes) to corresponding haptic patterns on the feedback interface, allowing independent processing and presentation of multiple sensory dimensions
Solution Approach 2:
The patent introduces a haptic feedback interface as an intermediary device that translates visual video data into tactile sensations, bridging the gap between visual information sources and tactile sensory perception without directly modifying the original video content
2Measurement precision
If rudimentary tactile presentation systems are used, then basic touch feedback is provided, but advanced haptic sensation and sensory resolution are not achieved
Solution Approach 1:
The system adds a tactile dimension to traditional visual video consumption by mapping two-dimensional video content onto a multi-dimensional haptic feedback interface that can represent spatial, temporal, and textural properties through touch
Solution Approach 2:
The patent replaces simple mechanical tactile indicators (like raised dots or spikes) with a more sophisticated haptic feedback system that uses controlled mechanical actuation to generate nuanced tactile sensations corresponding to video content
3Ease of operation
If haptic feedback interface is added to provide enhanced sensation, then user experience is improved, but device complexity increases
Solution Approach 1:
The haptic feedback interface is designed to work with multiple types of video content and usage scenarios, providing universal tactile feedback mechanisms that can represent various visual elements (motion, objects, scenes) through a single integrated system
Data Source
AI summary
A device for providing haptic sensation includes a haptic feedback interface. A plurality of videos each recording a real time or near-real time event in a three-dimensional real-world area from a different viewing angle is received and a user input via a mode selector in form of a gesture or a physical touch input is received to indicate a selection of an image-capture device is received. A plurality of different motion of a plurality of objects in an upcoming scene of a captured video is detected based on a look-ahead buffer of the video. A plurality of different haptic cues that includes the one or more movable haptic cues is generated based on the determined haptic feedback. Further, movement of the one or more movable haptic cues is controlled on the haptic feedback interface such that an inter-movement among the plurality of objects is discernible by tactioception.
