Haptic Display Regions Mapping Luminance to Prevent Monochrome Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displays with haptic feedback struggle to accurately convey gradational images, leading to erroneous recognition by users, as the haptic resolution exceeds human perception, resulting in feedback similar to touching a monochrome image.
Innovation Solution
A display system with a monitor that includes input detection regions and haptic feedback regions, where a data processor determines haptic output values based on image data and input detection results, allowing for precise haptic feedback corresponding to the luminance or color of each pixel, preventing erroneous recognition of gradational images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If haptic feedback is provided for each pixel of the image, then haptic feedback resolution is improved, but the user cannot identify gradation and may erroneously recognize the image as a monochrome image
Solution Approach 1:
The display screen is divided into multiple haptic feedback regions, and each region provides haptic feedback independently based on the luminance or color characteristics of the corresponding image area. This segmentation allows the system to provide differentiated haptic feedback for different regions while maintaining overall gradation information, preventing the user from perceiving the image as monochrome.
Solution Approach 2:
Different haptic feedback characteristics are applied to different haptic feedback regions based on their corresponding image content. Regions with different luminance or color values receive different haptic feedback intensities or patterns, preserving the local quality and gradation information of the original image while providing tactile feedback.
2Manufacturing precision
If haptic feedback intensity corresponds to color intensity of each pixel, then haptic feedback detail is improved, but feedback becomes similar to monochrome image touching when resolution exceeds human perception
Solution Approach 1:
The patent transitions from providing haptic feedback at the pixel level to providing feedback at a coarser regional level. By mapping multiple pixels to a single haptic feedback region and aggregating their color information, the system preserves essential image gradation details while avoiding the harmful effect of excessive resolution that causes erroneous monochrome recognition.

AI summary
A display includes: a monitor that includes an input/output region and performs haptic feedback when detecting an input from an operator while an image is displayed, the input/output region being obtained by superimposing a first region for displaying an image, a second region including a plurality of input detection regions each for detecting an input from an operator, and a third region including a plurality of haptic feedback regions each for performing haptic feedback to the operator; and a data processor that determines a haptic output value in each of the plurality of haptic feedback regions on the basis of image data of an image being displayed on the first region and a detection result of an input from an operator in each of the plurality of input detection regions.
