Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In non-contact gesture-based input systems, users face difficulties in recognizing intermediate gesture states, leading to improper inputs as they transition between distinct gestures, causing unintended selections due to ambiguity in gesture recognition.

Innovation Solution

A display device with an input operation detector, display processor, reception processor, and change processor that detects and processes gesture operations, displaying icons in varying forms to indicate movement and selection actions, and gradually changes icon forms during transition states to clarify the user's gesture intentions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If gesture recognition system transitions between distinct gesture states, then gesture operation functionality is improved, but intermediate gesture state recognition accuracy deteriorates

Engineering Contradiction:

Improvegesture operation functionalityVSAvoidintermediate gesture state recognition accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system provides visual feedback by displaying an input operation icon that changes its display form according to the detected gesture state. During intermediate gesture states, the icon gradually transitions between display forms corresponding to different gestures, allowing users to recognize their current gesture state and adjust accordingly, thus preventing improper inputs while maintaining gesture operation versatility

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The input operation icon serves as an intermediary between the gesture recognition system and the user. It visually represents the detected gesture state and provides continuous feedback during transitions, bridging the gap between ambiguous intermediate states and user understanding, thereby improving recognition accuracy without sacrificing gesture functionality

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If gesture transition speed is increased, then input efficiency is improved, but gesture state recognition accuracy deteriorates

Engineering Contradiction:

Improveinput efficiencyVSAvoidgesture state recognition accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The display form of the input operation icon changes continuously or gradually during gesture transitions rather than abruptly switching. This continuous visual feedback maintains the useful action of gesture input while providing sufficient information for accurate state recognition, balancing input efficiency with recognition accuracy

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A display device includes an input operation detector that detects an input operation including a gesture operation, a display processor that displays an input operation icon in a first display form when a first gesture operation is detected and displays the input operation icon in a second display form when a second gesture operation is detected, a reception processor that receives a movement operation when the first gesture operation is detected and receives a selection operation when the second gesture operation is detected, and a change processor that, when a third gesture operation is detected, gradually or continuously changes a display form of the input operation icon between the first display form and the second display form.
