Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing information processing technologies face challenges in displaying projected information on a plane due to shading effects caused by objects like hands or pens, making it difficult to see the projected content.

Innovation Solution

An information processing device and method that sets an input auxiliary region based on sensing results, allowing the display of a starting point of input within this region to avoid shading, using a control unit to manage the projection and display of input information, including the use of a projector and sensors to recognize and adjust for the presence of operators like hands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If information is projected on a plane using a projector, then information display is achieved, but visibility is reduced due to shading from shielding objects like hands or pens

Engineering Contradiction:

Improvevisibility of projected informationVSAvoidshading effect from shielding objects

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary display element (such as a display device or augmented reality overlay) that shows input information in a position not affected by shading from shielding objects. This intermediary displays the input information at a location separate from the direct projection path, allowing users to view input data even when shielding objects block the original projection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the projector projects information directly on the plane, then simple display is achieved, but the input information becomes difficult to see when shielding objects are present

Engineering Contradiction:

Improveease of viewing input informationVSAvoidvisibility of input information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent moves the display of input information from the two-dimensional projection plane to another dimension or spatial location that is not blocked by shielding objects. This could involve displaying information in three-dimensional space, on a different plane, or using a display device positioned where shielding objects do not interfere with visibility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Device complexity

If the projection system uses a fixed projection path, then system simplicity is maintained, but shading from operator objects blocks the projected content

Engineering Contradiction:

Improveprojection system complexityVSAvoidshading obstruction

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces dynamic adjustment capabilities to the projection system, allowing it to adapt its projection path or display location based on the presence of shielding objects. The system can dynamically change the projection angle, position, or switch to alternative display methods when obstruction is detected, making the system flexible enough to overcome shading issues without requiring complete system redesign.
