Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing haptic-feedback technologies struggle to effectively present information mapped in space without relying on vision or audition, limiting their ability to convey spatial information effectively.
Innovation Solution
A haptic-feedback presenting apparatus and system that includes a mapping-information acquisition part, a region detection part, and a haptic-feedback arithmetic part, which acquires and processes spatial information to determine if it exceeds a threshold, and calculates and presents haptic feedback to the user based on this determination, adjusting the intensity and direction of the feedback accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If haptic feedback is used to present spatial information, then information can be transmitted without vision and audition, but the ability to convey complex spatial information effectively is limited
Solution Approach 1:
The haptic feedback is segmented into multiple independent actuators arranged in a matrix pattern, where each actuator can be controlled independently to represent different spatial locations. This segmentation allows complex spatial information to be broken down into discrete haptic signals that can be processed and transmitted effectively without losing spatial relationships.
Solution Approach 2:
The patent transitions from traditional one-dimensional or two-dimensional information presentation to three-dimensional spatial haptic feedback. By arranging actuators in a three-dimensional matrix and mapping spatial coordinates to haptic actuator positions, the system adds a spatial dimension to information transmission, enabling effective conveyance of spatial data through touch alone.
2Loss of information
If haptic feedback intensity is increased to improve information perception, then user awareness increases, but user comfort may deteriorate
Solution Approach 1:
Different regions of the haptic feedback device apply different vibration intensities and patterns tailored to the specific spatial information being conveyed. Critical spatial locations receive stronger or more distinctive haptic signals, while less important areas use milder feedback. This localized differentiation maintains user comfort while ensuring important spatial information is clearly perceived.
Solution Approach 2:
The haptic feedback system dynamically adjusts vibration intensity, frequency, and pattern based on the importance and type of spatial information being transmitted. The control system modulates feedback parameters in real-time, increasing intensity only when necessary for critical information and reducing it for routine spatial data, thereby maintaining optimal balance between information awareness and user comfort.

AI summary
An object of the present technology is to provide a haptic-feedback presenting apparatus, a haptic-feedback presenting system, and a haptic-feedback presenting method capable of presenting information mapped in space without vision and audition. A haptic-feedback presenting apparatus according to the present technology includes a mapping-information acquisition part, a region detection part, and a haptic-feedback arithmetic part. The mapping-information acquisition part acquires mapping information that is information mapped in space. The region detection part sets a detection-target region, and determines whether or not the mapping information included in the detection-target region satisfies a condition, such as being a threshold or more. The haptic-feedback arithmetic part calculates a haptic feedback to be presented to a user on the basis of a determination result from the region detection part.
