Solution Overview

Problem

Information processing devices worn by users face inefficiencies in data communication when acquiring and displaying augmented reality information, as they often waste resources by requesting and discarding information for objects that have left the user's field of view during data retrieval.

Innovation Solution

The device identifies an attention region and a peripheral region within the user's field of view, requesting and receiving information only for objects within the attention region during the time the user is likely to be paying attention, and optionally for objects in the peripheral region, optimizing data communication by reducing unnecessary data transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the information processing device requests and receives related information of all objects within the user's field of view from a server, then the user can potentially access information about all visible objects, but data communication becomes inefficient and wasteful when the user's view changes during data retrieval

Engineering Contradiction:
Improveinformation utilityVSAvoiddata communication efficiency
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent applies local quality by differentiating between objects in the attention region and peripheral region, requesting detailed information only for attention region objects while requesting minimal information for peripheral region objects. This selective information acquisition based on spatial location resolves the contradiction by optimizing data communication efficiency without sacrificing information utility where it matters most.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by continuously monitoring the user's line of sight and dynamically adjusting which objects are classified as attention region versus peripheral region objects. This dynamic classification allows the system to adapt information requests to the user's current viewing state, ensuring information is retrieved efficiently based on real-time attention patterns rather than static field-of-view assumptions.

Inventive Principle:
Principle #15Dynamics

2Loss of information

If the information processing device acquires related information for all objects in the field of view, then comprehensive information is available, but processing time increases and data may be discarded if the user's view changes during acquisition

Engineering Contradiction:
Improveinformation completenessVSAvoiddata acquisition time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent applies partial action by requesting only the necessary portion of information - detailed information for attention region objects and minimal information for peripheral region objects. This partial information acquisition strategy resolves the contradiction by obtaining sufficient information for the user's current needs without the time cost of acquiring complete information for all objects in the field of view.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent implements preliminary action by pre-classifying objects into attention and peripheral regions based on the user's current line of sight before initiating data requests. This preliminary classification enables the system to prioritize information acquisition for objects the user is actually looking at, reducing overall data acquisition time while maintaining information completeness for relevant objects.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the device requests information for objects that may leave the field of view during data retrieval, then no information is lost, but unnecessary data transfer occurs when the user's view has already changed

Engineering Contradiction:
Improveinformation delivery reliabilityVSAvoiddata transfer waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent applies local quality by implementing different information request strategies for different spatial zones - attention region objects receive full information requests while peripheral region objects receive minimal information requests. This spatial differentiation resolves the contradiction by ensuring reliable information delivery for objects the user is actually viewing while minimizing data transfer waste for objects likely to leave the field of view.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements self-service by enabling the information processing device to autonomously determine which objects warrant detailed information requests based on their position relative to the user's line of sight. This autonomous decision-making resolves the contradiction by eliminating unnecessary data transfer for objects that will not be viewed, while maintaining reliable information delivery for objects in the attention region.

Inventive Principle:
Principle #25Self-service

AI summary

An information processing device according to one embodiment includes a detection unit that detects an attention region corresponding to a user's sense of sight, an identification unit that identifies a first object overlapping the attention region from one or more objects existing in a space where the user is located, a request unit that makes a request for first object information related to the first object to another computer during a first time period where the first object overlaps the attention region, and a receiving unit that receives the first object information transmitted from the another computer in response to the request during the first time period.
