Solution Overview

Problem

Conventional glass-type terminals waste resources and time by processing all objects within the user's viewing angle, rather than focusing on specific objects of interest, due to the mismatch between the user's actual viewing angle and the camera's recognition range.

Innovation Solution

A glass-type terminal with a camera, infrared light emitting part, and controller that selectively processes and tracks specific objects of interest by displaying a marker on the display unit, allowing the user to intuitively select and receive visual information related to those objects, even when they are out of the camera's recognition range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If image processing is performed on all objects within the user's viewing angle, then comprehensive object recognition is achieved, but resource consumption increases and processing time is extended

Engineering Contradiction:
Improveobject recognition accuracyVSAvoidimage processing efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent segments the field of view into multiple regions and selectively performs image processing only on specific regions containing objects of interest, rather than processing all objects uniformly. This is achieved by dividing the viewing angle into first, second, and third regions, with different processing strategies applied to each region based on object importance and user interest.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different image processing qualities and levels to different spatial regions. High-priority objects in the first region receive full processing, while objects in other regions receive reduced or no processing. This local differentiation of processing quality optimizes resource allocation while maintaining recognition accuracy for important objects.

Inventive Principle:
Principle #3Local quality

2Loss of information

If image processing is performed on all objects within the viewing angle, then complete object information is obtained, but processing time is excessive and resources are wasted

Engineering Contradiction:
Improveobject information completenessVSAvoidimage processing time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent extracts and identifies objects of interest from the complete field of view, then focuses processing resources only on those extracted objects. The controller identifies specific objects within the viewing angle and performs detailed image processing only on those objects, rather than processing all objects equally, thereby reducing processing time while maintaining information completeness for relevant objects.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies partial action by performing complete image processing only on selected objects of interest while using reduced or no processing on other objects in the field of view. This selective partial processing maintains information quality for important objects while significantly reducing overall processing time and resource consumption.

Inventive Principle:
Principle #16Partial or excessive action

3Loss of information

If the terminal processes all objects in the viewing angle, then comprehensive visual information is provided, but resource consumption increases

Engineering Contradiction:
Improvevisual information completenessVSAvoidresource consumption
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent segments the viewing angle into multiple regions and selectively processes only those regions containing objects of interest. By dividing the field of view and applying different processing strategies to each segment, the system maintains visual information completeness for important objects while reducing energy consumption through selective processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by providing high-quality visual information processing only in specific local regions where objects of interest are located, while reducing or eliminating processing in other regions. This spatial differentiation of processing quality ensures information completeness where needed while minimizing overall energy consumption.

Inventive Principle:
Principle #3Local quality

AI summary

An eyewear type terminal includes a main body, a camera, an infrared light emitting part, a display unit and a controller. The main body is wearable on a user's head. The camera is coupled to the main body, and obtains a first image using at least one image sensor. The infrared light emitting part is disposed to be spaced apart from the camera at a predetermined distance, and transmits infrared light using at least one infrared light emitting device. The display unit outputs the first image, and displays a marker moving along a first input signal on the first image when the infrared light emitting part is driven. The controller obtains a second image of an object existing in the area where the marker is displayed using the at least one infrared light emitting part and the camera, when a second input signal is sensed, and outputs visual information related to the obtained second image to be adjacent to the object.
