Haptic Chair Motion Simulation With Independent Sensory Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia systems primarily stimulate only two senses, sight and hearing, failing to fully engage the human perception of movement which involves three sensory systems: visual, vestibular, and haptic, limiting the immersive experience in audiovisual content consumption.
Innovation Solution
A device with multiple movable parts, including a headrest, armrests, seat, legrest, and backrest, each capable of independent movement and rotation, combined with an array of movable stamps for tactile stimulation, to simultaneously and independently stimulate the vestibular and kinaesthetic senses, enhancing the haptic experience without physically moving the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a Stewart's platform is used to provide motion simulation, then the vestibular sense is stimulated, but the device complexity and cost increase significantly
Solution Approach 1:
The patent divides the haptic chair into multiple independent movable parts (headrest, armrests, seat, legrest, backrest) that can be controlled separately. Each part can be actuated independently to stimulate different sensory systems, replacing the need for a complex Stewart's platform while achieving comprehensive motion simulation through segmented functional modules.
2Reliability
If only vestibular stimulation is provided through seat movement, then motion simulation is achieved, but the haptic experience remains incomplete without kinaesthetic and tactile engagement
Solution Approach 1:
The haptic chair is designed as a multi-functional device where different components serve multiple sensory purposes. The headrest, armrests, seat, legrest, and backrest can be independently actuated to provide vestibular, kinaesthetic, and tactile stimulation, making the device versatile in engaging all three human perception systems for comprehensive motion simulation.
3Adaptability or versatility
If multiple movable parts are added to stimulate different senses, then the haptic experience is enhanced, but the device complexity increases
Solution Approach 1:
The patent implements dynamic control of multiple movable parts where each component (headrest, armrests, seat, legrest, backrest) can be independently actuated and repositioned based on the required sensory stimulation. This dynamic adaptability allows the system to provide comprehensive haptic feedback while managing complexity through independent, modular actuation mechanisms rather than a rigid complex structure.

AI summary
A device for providing the illusion of motion consists of at least two movable parts for stimulating the vestibular sense and the kinaesthetic sense of a user independently from each other. A moving headrest is provided for stimulating the vestibular sense of a user and a moving armrest is provided for stimulating the kinaesthetic sense of a user.
