Haptic Feedback Wearable for Motion Sickness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing motion sickness are inadequate, particularly in scenarios where visual and inertial perceptions of motion conflict, and there is a need for a wearable device that provides effective directional feedback without medication side effects and enhances neural rehabilitation.
Innovation Solution
A wearable device using transducers that convert electrical signals into tactile sensations such as pressure, vibration, or airflow, providing a third motion perception input by actively indicating direction and magnitude of motion through haptic feedback, thereby reducing the conflict between inertial and visual perceptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medications are used to reduce motion sickness, then motion sickness is reduced, but side effects such as sleepiness occur
Solution Approach 1:
The patent replaces the chemical mechanism of medications with a mechanical/physical haptic feedback system. Transducers provide tactile sensations that directly communicate motion information to the user's somatosensory system, eliminating the need for pharmacological intervention and its associated side effects while maintaining motion sickness reduction effectiveness
Solution Approach 2:
The haptic feedback system introduces a new intermediary (tactile feedback through transducers) between the conflicting sensory inputs. This intermediary provides a third channel of motion perception that helps resolve the conflict between visual and inertial signals without requiring chemical mediation through medications
2Reliability
If existing motion sickness reduction methods are used, then some relief may be provided, but they are not ideal and lack effectiveness in resolving sensory conflict
Solution Approach 1:
The haptic feedback system dynamically adjusts its operation based on real-time motion data from sensors. The controller continuously monitors motion parameters and modulates transducer output accordingly, allowing the system to adapt to varying motion scenarios and provide optimal feedback for different types and intensities of motion-induced sensory conflict
Solution Approach 2:
The system implements a closed-loop feedback mechanism where sensors detect motion, the controller processes this information, and transducers provide appropriate haptic feedback. This continuous feedback loop enables the system to respond adaptively to changing motion conditions and effectively resolve sensory conflict across diverse scenarios
3Productivity
If conventional isolated neural rehabilitation routines are used, then specific therapies can be applied, but they lack connection and overall effectiveness
Solution Approach 1:
The patent merges multiple isolated rehabilitation therapies into a single integrated system. Conventional rehabilitation routines are combined with haptic feedback delivery and synchronized brain stimulation, creating a unified connected approach that enhances overall rehabilitation effectiveness while managing system complexity through coordinated integration
4Loss of information
If haptic feedback transducers are activated to provide directional indication, then directional feedback is provided, but energy consumption increases
Solution Approach 1:
The system activates only the necessary subset of transducers required to provide accurate directional feedback at any given moment. Rather than operating all transducers continuously, the controller selectively activates specific transducers based on the current motion context and directional information needs, reducing overall energy consumption while maintaining feedback accuracy
Solution Approach 2:
The haptic feedback system operates periodically rather than continuously, activating transducers only when motion events occur that require feedback. This periodic operation synchronized with actual motion events reduces energy consumption compared to continuous operation, while maintaining directional feedback accuracy when needed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reduces motion sickness by providing a third motion perception input that acts as a 'tie-breaker' between inertial and visual cues, enhancing sensory inputs and improving neural rehabilitation by synchronizing haptic feedback with rehabilitation routines.
Implementation Method 1
The device provides haptic feedback using transducers that convert electrical signals to a tactile sensation such as pressure, vibration, electrical stimulation (including all types of waveform signal), temperature, or airflow

AI summary
A device for motion sickness reduction, directional indication, and neural rehabilitation that provides three modes of operation. The device operates by providing haptic feedback using transducers that convert electrical signals to a tactile sensation such as pressure, vibration, electrical stimulation, temperature, or airflow. The transducers are located at different locations on the body of a user, and actively change their operation to indicate a direction of motion or rotation to the user through haptic (tactile) feedback. This tactile feedback can be used to reduce motion sickness, provide directional indication, and enhance neural rehabilitation.
