Half Mirror Visual Tactile Integrated Presentation Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to provide a realistic experience of two-dimensional and three-dimensional object textures due to separate visual and tactile information presentation units, leading to incomplete cross-modal effects and limited tactile information handling.
Innovation Solution
A visual sense-and-tactile sense integrated presentation device using a half mirror with a visual sense presentation body on one side and a tactile sense presentation body on the other, optically aligned to coincide the virtual image with the tactile sense presentation, along with a finger illuminator to enhance realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If visual information display unit and tactile information presentation unit are separately arranged, then device complexity is reduced, but the portion actually touched by user differs from displayed object portion, failing to achieve cross-modal effect
Solution Approach 1:
The patent merges the visual information display unit and tactile information presentation unit into a single integrated presentation unit. This allows the same physical location to simultaneously provide both visual and tactile information, enabling the cross-modal effect where the portion touched by the user corresponds exactly to the displayed object portion.
Solution Approach 2:
The patent adds a tactile dimension to the visual display by integrating tactile information presentation capabilities within the visual display unit itself. This multi-dimensional approach allows simultaneous engagement of visual and tactile senses at the same spatial location, creating enhanced cross-modal perception.
2Adaptability or versatility
If image information output means and tactile information output means are stacked, then tactile information can be output while overlapping with image display, but tactile information output means cannot be easily replaced and image becomes shadow of user's hand
Solution Approach 1:
The patent segments the presentation unit into functionally independent modules: a visual information display module and a tactile information presentation module. This modular segmentation allows each module to be independently replaced or upgraded without affecting the other, solving the replacement difficulty issue while maintaining overlapping visual-tactile information output.
Solution Approach 2:
The patent introduces a half-mirror as an intermediary optical element that allows the visual display to be viewed while the tactile output means remains accessible below. This intermediary structure enables simultaneous access to both visual and tactile information without one obscuring the other, preventing the shadowing problem.
3Adaptability or versatility
If image information output means and tactile information output means are stacked, then tactile information can be output while overlapping with image display, but image of portion actually touched may not be easily seen
Solution Approach 1:
The half-mirror acts as an intermediary that separates the visual and tactile paths optically. It reflects the visual display upward while allowing tactile output to occur below, ensuring that the displayed image remains clearly visible and does not become obscured by the user's hand or the tactile output mechanism.
4Adaptability or versatility
If tactile information presentation unit is added to create cross-modal effect, then realistic texture experience is improved, but device complexity increases
Solution Approach 1:
The patent combines visual and tactile information presentation functions into a single integrated presentation unit, reducing overall device complexity compared to having completely separate units. This merging maintains the cross-modal effect while simplifying the system architecture.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a more realistic experience of object textures by synchronizing visual and tactile senses, allowing for various tactile presentations and avoiding shadow issues, thus improving the cross-modal effect and usability with three-dimensional objects.

AI summary
A visual sense-and-tactile sense integrated presentation device includes a half mirror, a visual sense presentation body that presents visual information about an object and is disposed on a mirror surface side of the half mirror, and a tactile sense presentation body that presents tactile information and is disposed to face the visual sense presentation body across the mirror surface of the half mirror at an optical distance from the half mirror equal to an optical distance between the half mirror and the visual sense presentation body.
